Method for manufacturing steel sheet for grinding and cutting granite stones

Abstract

The invention discloses a method for manufacturing a steel sheet for grinding and cutting granite stones, which comprises the following steps of: firstly, heating refined special steel U75V billets serving as a raw material; secondly, cogging, perform rough rolling and finish rolling; thirdly, slow cooling, leveling, aligning, drawing and performing cold treatment at room temperature; and finally, cutting, punching, nitriding and packing and the like to obtain the steel sheet for grinding and cutting the granite stones. The steel sheet has higher mechanical properties such as tensile strength, rigidity, wear resistance and the like; compared with the product produced from other materials, the steel sheet is more wear resistant and safer and the product quality is more stable and reliable;compared with imported products, the cost is lower and the applicability is higher; and the steel sheet is suitable for stone industries to reduce production cost, improve cost performance and enhance market competitive power.

Description

technical field [0001] The invention relates to a cutting tool for stone processing, in particular to a method for manufacturing a steel sheet for grinding and cutting granite stone. Background technique [0002] Granite is cut into a plate shape and polished, it is a decorative material for the construction industry, it is a modern urban construction, especially for public construction facilities, such as stadiums, stations, subways, buildings, squares, as well as homes, offices, shopping malls Commonly used materials for decoration and decoration of modern buildings such as shopping malls, supermarkets, and beautification of the environment. In my country's traditional stone processing production, after the introduction of foreign modern large-scale stone plate processing equipment and production technology in the past ten years, with the rapid development of my country's national economy and the increasing improvement of people's living standards, residents' attention to ...

Problems solved by technology

The reheating process causes the raw materials to be seriously decarburized again. If it is used in the cutting of stone saw blades, it will easily cause low tensile strength. The severe decarburization caused by the second heating will cause a huge change in the chemical composition, which will seriously change the mechanical properties of the old rails, resulting in It breaks, deviates, and the tension of the saw blade is loose, which causes the equipment to stop halfway to replace the saw blade, which seriously affects the production efficiency of stone materials, product quality and other adverse phenomena. In order to fill in the correct selection, use steel materials that meet the mechanical properties of sand saw equipment
