1. Types of Skate Shoes
Skate shoes are skates worn when skating. Skating events can generally be divided into three categories: speed skating, figure skating and ice hockey. Project characteristics and requirements, skate shoes are also mainly divided into three categories:
1. Speed skating skate shoes
Speed skates can be divided into ‘ There are two types of high-speed skating knives
, ‘high-speed skating knives’ and ‘short-track speed skating knives’. The high-speed skating knives have long bodies, narrow and flat blades, large skating area, low frictional resistance, and short shoe waists, which are convenient for athletes to lower their center of gravity and reduce air. resistance.
The short track speed skating blade has a short blade, the bottom of the blade has an arc, and the contact area with the ice surface is small, which is convenient for athletes to slide forward in the curve. When the size is very large, the skates will not touch the ice surface. At present, the knife holders of the special short-track speed skates are mostly movable, for athletes to choose according to their own habits and preferences.
2, Ice hockey shoes
The hockey knives are short in height, large in curvature, and thick in blade. Features of high strength. It should be noted that the ice hockey goalkeeper’s skate is different from other athletes’ skates. It is made of all-metal, and the blade is short and flat. This design is to prevent the ball from leaking into the net.
3. Figure skating shoes
The body of the figure skating blade is generally shorter, but slightly longer than the ice hockey blade, and there are several ice teeth at the front of the blade , allowing players to control the balance, the middle and front arcs are similar to the hockey knife (non-goalie version). At the same time, figure skating shoes are mostly designed with a high waist to provide sufficient support when jumping.
Figure skating shoes are different according to the requirements of amateur and professional, and the practice is also different. The amateur basically uses PVC bottom + PVC leather, and the professional basically uses leather bottom and leather, and the inner thickness is thicker and harder. Harden.
The difference between the two and three kinds of skate shoes
The difference between the three kinds of skate shoes is mainly due to different design features, which is also the difference caused by different project features :
1. The main feature of speed skating is fast speed, so the speed skating blade is very long, the blade is narrow and flat, so that the skating area is large and the friction resistance is small, and the waist of the shoe is short in order to lower the body. center of gravity, reducing air resistance.
2. Ice hockey is very confrontational. Therefore, the toe cap of ice hockey shoes is very hard, the waist of the shoe is high, the upper is very thick, and the body of the skate knife is very short.
3. Figure skating is very difficult and requires high stability. Therefore, the blade is wider and there is a groove in the middle.
Three, what kinds of materials are there for the skates?
The skates of the skates are relatively sharp, generally made of steel, and its material is mainly There are the following types:
1. Carbon tool steel
Carbon tool steel is generally used by beginners, and the different quality of skates mainly depends on Carbon content, although the hardness of the blades used in the same project are all to the same standard, but due to the different grades of steel, under the same conditions, higher grade steel will keep the blade edge life longer.
2, stainless steel, high-grade carbon steel or high-speed tool steel
Generally used by skilled or intermediate enthusiasts, the steel for skates is of higher grade, and its Has strong corrosion resistance and enables skaters to improve frequent jumps and spins. This type of ice blade is usually coated with a layer of titanium compound. After grinding, the maximum hardness on both sides can reach Rockwell hardness 85, which reduces the friction between the blade and the ice. After cold working, it has very high hardness and good corrosion resistance. .
3. Powder alloy and coated high-speed steel
Generally used for international competitions, skate shoes for international competitions, the skates generally have to be durable. Grinding, anti-corrosion, working surface suitable for different ice surface hardness, suitable for frequent jumping, sliding, and not easy to connect and desolder with soles, etc., and the coated high-speed steel is characterized by a thin nitride coating on both sides of the blade. Titanium or titanium carbide, the blade is made of bimetallic composite steel as a whole. After grinding and sharpening, a blade with high hardness and roughness like a mirror surface is formed on both sides, thus greatly improving the life of the blade of the blade without reducing the toughness of the blade.
4. Powder metal tool steel
It has the absolute best sliding speed and wear resistance, and only a few foreign companies produce it.
