Large-standard high-speed resin heavy duty grinding wheel for grinding steel billet

Abstract

The preparation method for the large-standard high-speed resin heavy duty grinding wheel for grinding a steel billet comprises the steps that a dedicated binding agent for a high-performance modified high polymer matrix phenolic resin grinding wheel is prepared by using phenolic resin, xylok resin, butyral resin, iron pyrite, cryolite, light magnesium oxide, barite, 400 # carborundum and calcium carbonate, dedicated formulas for a grinding layer and a core layer are separately designed by using grinding materials such as fused alumina zirconia, aluminium oxide sintered corundum, black silicon carbide, furfural, dibutyl ester, fibers and steel rings, and the large-standard high-speed resin heavy duty grinding wheel for grinding the steel billet is prepared by adopting a dual-phase reinforced composite technology and structure. According to the large-standard high-speed resin heavy duty grinding wheel for grinding the steel billet, the linear velocity is equal or greater than 90 m / s to 120 m / s, the maximum diameter is 925 mm, the thickness is 125 mm, and the tensile and breaking strength and the grinding efficiency of the grinding wheel are greatly improved. When the large-standard high-speed resin heavy duty grinding wheel for grinding the steel billet is under heavy duty, the adaptability of the condition of grinding range is wide, and the linear velocity is high. The grinding efficiency reaches a thickness of 1 cm at a time, the problems that an existing grinding wheel cannot adapt to a steel billet, and the heavy duty grinding of steel is difficult are solved well, and the increasing development requirements of the iron and steel industry are met.

Description

technical field [0001] The invention relates to a large-scale high-speed resin heavy-duty grinding steel billet grinding wheel and a preparation method thereof. Background technique [0002] Special steel is the manufacture of special steel, which is a strategic basic industry of the national economy. In order to adapt to the continuous transformation and upgrading of high-end machinery and equipment, aerospace, automobiles, engines, and shipbuilding industries, and to improve the manufacturing level of the steel industry, billet grinding is especially important for the steel industry. The key process of special steel production is to identify the quality of steel plates through grinding, and process them to the specified specifications. The grinding load of the grinding machine is large, which is convenient for mechanization and automation, so the grinding efficiency is greatly improved, and the amount of metal removed per hour can be as high as 500-800Kg: this process is t...
