Embodiment 1

[0008] Preparation of 4mm thick ice hockey blade slab material

[0009] First, according to the mass ratio C: 0.7%; Mn: 0.6%; Cr: 14%; Co: 1%; After electroslag remelting, the electroslag ingot is obtained, and then forged into a cuboid billet with a forging ratio of 3:1 and a forging temperature of 1080°C. The thickness of the rolled slab was 4 mm. The hot-rolled slab is subjected to quenching and tempering treatment. The quenching process is 1030°C for 20 minutes and then oil cooling, and the tempering process is 350°C for 10 minutes to obtain ice hockey skate slab materials that meet the requirements, and then cut according to needs. The surface is polished to obtain a hockey blade. After performance testing, the hardness of the material reaches 60HRC, and the impact toughness is 120J / cm 2 , The bending strength is 4450MPa, and the performance fully meets the application requirements.

Embodiment 2

[0011] Preparation of 6mm thick ice hockey blade slab material

[0012] First, according to the mass ratio of C: 1.0%; Mn: 0.8%; Cr: 16%; Co: 1.5%; After electroslag remelting, the electroslag ingot is obtained, and then forged into a cuboid billet, the forging ratio is 3:1, and the forging temperature is 1230°C. Then the forged billet is hot-rolled into a slab. The thickness of the rolled slab was 6 mm. The hot-rolled slab is subjected to quenching and tempering treatment. The quenching process is 1050°C for 20 minutes and then oil cooling, and the tempering process is 400°C for 10 minutes to obtain ice hockey skate slab materials that meet the requirements, and then cut according to needs. The surface is polished to obtain a hockey blade. After performance testing, the hardness of the material reaches 61HRC, and the impact toughness is 116J / cm 2 , The bending strength is 4500MPa, and the performance fully meets the application requirements.

Abstract

The invention discloses a method for preparing ice hockey blade material, which belongs to the field of metal materials. According to the mass ratio of the present invention C: 0.7-1.0%; Mn: 0.6-0.8%; Cr: 14-16%; Co: 1-1.5%; N: 0.1-0.15%, the ratio of Co to N is 10:1, and The amount is Fe for batching, and then the induction melting furnace is used to melt the ingot to obtain the ingot, and the ingot is electroslag remelted to obtain the electroslag ingot, and then forged into a cuboid billet, the forging ratio is 3:1, and the forging temperature is 1080-1230°C , and then hot rolling the forged body into a slab, the temperature of the hot rolling is 1150°C-1200°C, and the thickness of the slab after hot rolling is 4-6mm. The hot-rolled slab is subjected to quenching and tempering treatment, the quenching process is 1030‑1050 °C, and oil cooling is performed after holding the heat for 20 minutes. The tempering process is 350-400° C., and the heat preservation is 10-15 minutes, and the ice hockey blade slab material whose performance meets the requirements is obtained. The invention has simple process and low cost, and is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of metal materials and relates to a method for preparing ice hockey blade materials. Background technique [0002] Ice skates are the basis of ice sports. For ice hockey, ice hockey skates are required to have high impact toughness, bending strength and certain hardness, so as to ensure that the skates have considerable wear resistance and small surface roughness. Although researchers have modified and strengthened the skates by various methods such as surface modification and changing the radian to improve their overall performance, but from the perspective of application effects, the performance of ice hockey skates is still not fully satisfactory due to the low performance of the main material of the skates. or training needs. Especially for domestic ice hockey skates, it is difficult to reach the level of some imported brand skates in terms of sharpening cycle and overall service life. Therefore, it is urgent to...
