POSCO started supporting the team last year after CEO Ohjoon Kwon watched the team take the bronze medal at the 2017 World Championships. As shown in the documentary, the athletes were playing on insufficient sledges that would often break down and cause injuries. Some players were fixing their own sledges between matches, others made do with what they had. CEO Kwon knew POSCO had the solutions for the team and started a project with sledge-maker Massive Blade to revamp the sledges for the team. Now, ahead of the 2018 PyeongChang Winter Paralympics, the team is equipped and ready with the world’s leading technology.

Parallel: A Documentary

Parallel was directed by Kyungman Kim in 2012. He wanted to make the movie to document the para ice hockey players’ endurance and grit in overcoming their physical limitations through the sport. “However, as I started editing the footage and putting it all together, I noticed how happy the players looked on the ice. That’s when I decided the documentary was going to be about happiness – what it really means to be happy. That’s what I want to share with viewers,” said director Kim.

That’s exactly what the movie delivers. Of course, the players face challenges every day due to their injuries and physical conditions, but the interviews in the documentary reveal the players to be genuinely happy and grateful for their sport. Seunghwan Jung, one of the players, says, “I used to wish I had legs all the time, but when I started playing hockey, the thought just never crossed my mind. In a way, the sport has allowed me to accept myself… understand myself.”

For many of the players, playing para ice hockey has been a healing process, but it doesn’t end there. The team is as competitive as any other Olympic team, and even with a lack of spectators and interest in the sport, the national team has produced impressive results. In the 2010 Vancouver Winter Paralympics, the team placed 6th, and then 7th in Sochi in 2014. This is even more remarkable given the poor equipment, especially the sledges, they were using at the time.

POSCO Gives Ice Sledges a Technological Makeover

In order to qualify as a para ice hockey player, a person must have a physical impairment in the lower part of their body, but this can come in many different forms. As a result, one of the biggest challenges teams face is finding sledges that fit, protect and enhance each player. Before POSCO signed on as a sponsor, the Korean National Team relied on expensive imported sledges from Canada that were heavy and susceptible to structural damage from harsh contact. On average, 5 to 7 sledges required repair work during a single game. In an attempt to produce the first domestic sledge, POSCO’s researchers jumped on board to provide sledge-producer Massive Blade the materials for a lightweight, strong and corrosion resistant sledge.

Researchers at POSCO’s Research Institute of Industrial Science & Technology (RIST), came up with a way to use magnesium as the main material for the sledge frame. Magnesium is one of the lightest materials available as it is one third lighter than aluminum, but it is extremely hard to treat and bend into shape. RIST not only developed the technology to treat magnesium, but also applied it to sledges for the first time in history. POSCO also provided its advanced high-manganese anti-vibration steel and stainless steel to finish off the new sledges, fit for a national team.

RIST researchers developed a processing technology to increase the moldability of magnesium.

Outfitted with the new sledges, the team beat out strong European teams in the 2017 World Championships to place 3rd, and just last month, they won a four-nation friendly tournament in Japan. Now, they have their eyes on an Olympic medal in PyeongChang.

Regardless of the results, POSCO will continue to support the Korean National Para Ice Hockey Team so they can continue doing what makes them and others around them happy.

Para ice hockey, previously called ice sledge hockey, may not be common to everyone, but many consider it the highlight of para-athletic events. A team is composed of athletes who have a physical impairment in the lower part of their body, so instead of wearing skates, they glide through the rink on ice sledges (also known as sleds).

Watch any para ice hockey match, and it will be surprising to see that there is as much, if not more physical contact than regular ice hockey. Although these athletes may be limited in their everyday movement, on ice, they appear to be flying on their sledges.

The thrill and intensity of the sport are just some of the reasons why steel-company POSCO continually supports the Korean national team and para-athletics in general. It is also why POSCO joined the mission to create specially-made sledges for the Korean National Para Ice Hockey Team.

Ice Sledges Make or Break the Match

Due to the nature of the sport, the sledges have to withstand various forms of physical contact such as body checking. They also have to move in complete unison with the players, almost like an additional limb, because it determines the player’s’ steering and control of direction.

So, the sledges have a direct impact on performance.

Some members of the Korean national team have been playing for over 18 years, and they know better than anyone the importance of their sledges in relationship to performance and results. Ideally, a sledge has to be light yet strong, able to absorb shock from external contact and fit the athlete’s body perfectly.

All of the sledges the Korean ice hockey team used were previously imported from Canada. The sledges were heavier and often could not withstand harsh contact. On average, 5 to 7 sledges were damaged during a game and required repair work.

That’s why Massive Blade, a company that specializes in ice sports equipment, decided to make the sledges domestically in Korea. When POSCO heard that Massive Blade was looking for a light and strong material to build the sledges out of, researchers jumped on board the mission to produce these new and improved sledges.

The First Domestic Sledge, Built with POSCO’s Technology

This first-of-its-kind sledge was made with POSCO’s new high-strength magnesium alloy, high-manganese anti-vibration steel and stainless steel. Meaning, they replaced the heavy aluminum alloys that made up the previous sledges with POSCO’s advanced materials.

Magnesium

Magnesium has a high specific strength (also known as the strength-to-weight ratio) and is about two-thirds lighter than aluminum. The downside is that it is challenging to mold, so it is not widely used despite its phenomenal lightweight and specific strength qualities. This is where POSCO’s Research Institute of Industrial Science & Technology (RIST) stepped in to provide a solution

RIST has been researching magnesium and its production technology for application in mountain bike frames and car frames for 3 years. As a result, RIST also owns the necessary equipment and machinery for processing and producing magnesium parts. In order to develop their technology for processing magnesium, RIST researcher Lee Mok-Young said they had to first identify the characteristics of the material, maintain the proper heat treatment temperature and optimize the accompanying tools for molding magnesium. The molding tool is a new, innovative technology that ultimately decides whether magnesium can be shaped into the necessary parts.

When the processing technology is applied to magnesium, it results in a material that is approximately twice as moldable as regular magnesium. As a result, magnesium was able to be applied to sledges for the first time ever.

High-Manganese Anti-Vibration Steel

High-manganese anti-vibration steel is another material that helped enhance the sledges. They applied it to the parts of the sledge with the most exposure to contact such as the front bar and bucket brackets to prevent injuries as well as to minimize structural deformities. High-manganese anti-vibration steel is widely used in buildings for shock absorption, and according to Kim Sung-Gyu, director of the Gwangyang Steel Commercialization Promotion Team, the anti-vibration properties of the steel make it possible to contain vibrations from external force within the metal. This means less shock is transferred to the players, minimizing the risk of injury.

Stainless Steel

Finally, POSCO’s stainless steel was applied to the sledge blades. There are two blades at the bottom of every sledge, and each blade is 3mm thick. It is important to use high-strength steel so that the thin blades can stay sharp and carry the weight of the sledge and player throughout the whole game. Plus, the blades have to hold the frame 8.5cm to 9.5cm above the ice so that the puck can pass through freely under the sledge. The length of the blade also cannot exceed one-third of the total length of the sledge.

That’s a lot of work for just two blades, and that’s why POSCO’s stainless steel was applied. Besides the fact that it has optimal high-strength, hardness and ductility qualities, stainless steel is corrosion resistant, an important factor for blades constantly exposed to water and ice.

Aside from choosing the right materials, POSCO’s RIST researchers spent the most time trying to understand the difficulties and discomfort the para-athletes face on the sledges. It is true the sledges have to be light and strong, but there are further limitations to gauge precise movement and direction during an intense and dynamic game.

That’s why the researchers scrapped the project in its final stages multiple times to start over. During the process, they made numerous models and constantly talked with the players, coaches and the director. Not only that, the RIST researchers also consulted POSCO’s engineers about technical issues related to the materials. The finished product is really the accumulation of intensive research and running back and forth between the rink, the RIST research lab and POSCO offices.

National team members are adjusting to the new, upgraded sledges

The result of their collaboration is a sledge that is 34 percent lighter and capable of absorbing greater shock than the previous sledges.

The players are already adjusting to their new equipment and it won’t be long until they can test them out in an actual match. POSCO will continue to support para-athletes and the Korean National Para Ice Hockey Team so they can focus on their intensive training without worrying about sledge malfunctions and injuries.

TO (a safe) VICTORY!
