Problems solved by technology

In the existing technology, the use of conventional heat treatment, forging, cutting and other processes often leads to low wear resistance or insufficient strength and elasticity of steel products, and it is difficult to meet the comprehensive requirements of skateboards for performance.
The deformation of the skateboard edge caused by poor strength and wear resistance, and the lack of elasticity of the front wing of the skateboard will directly affect the service life and performance of the finished sled and skateboard, and it is also not conducive to the level of athletes in the competition.

Abstract

The invention provides structural steel for a sled alloy sliding board. The manner that overall annealing is performed firstly, then local annealing is performed, and coating depositing is performed is adopted, the sled sliding board structural steel is made to acquire sufficient strength and hardness, and meanwhile, the elastic performance of a front wing part is also guaranteed. The process thatdiamond coating depositing is performed after heat treatment can remarkably enhance the abrasion resistance of a structural steel product, and therefore the performance of the sled sliding board is improved, and the service life of the sled sliding board is prolonged. Special alloy elements and matching are adopted for the structural steel for the sled alloy sliding board, on the basis of conventional ice skate blade steel, the contents of Mn, Ni, Cr, Co and Al are all adjusted, especially according to the relationship of strength, hardness and elasticity, the content of the Cr element is reduced, and therefore the final structural steel product acquires good comprehensive performance.

Description

technical field [0001] The invention relates to the field of ice and snow sports equipment, in particular to a section steel for a sled alloy skateboard. Background technique [0002] As one of the seven major events of the Winter Olympics (ice hockey, curling, biathlon, skating, skiing and bobsleigh, sled), modern sled sports can be divided into rudderless and ruddered, single sled and wide sled , riding and horizontal, as well as traction, electric and sailing. The bottom slide of the sled is usually made of section steel. The slide is a pair of left and right parallel arrangements, and the length must not exceed 45 centimeters. The front wings of the slide need to maintain a certain degree of elasticity to facilitate turning and manipulation. [0003] In order to meet the requirements of sled sports, the steel used for the sled board needs to have good mechanical properties and surface quality. There should be no cracks, air bubbles, inclusions and other defects on the ...
