Problems solved by technology

[0002] At present, for the cutting and processing of high-strength refractory bricks used in high-temperature furnaces, some manufacturers use traditional grinding wheels for smoothing and metal saw blade processing, and the efficiency of this method is very low; generally large-scale steel factories use diamond saws imported from abroad. The raw materials are expensive, the price is high, and the use of foreign products is not only costly, but also the processing tools are subject to foreign companies, which makes the work progress of domestic steel mills very passive.

Abstract

A diamond saw bit for machining the refractory brick of high-temp furnace is prepared through proportionally mixing the fine particles of W, Co, Cu, Sn and Fe with diamond particles, stirring, loading in mould, high-temp and -pressure pressing to obtain alloy knives, and welding them onto circumference of a steel disc.

Description

technical field [0001] The invention relates to a diamond saw blade, in particular to a diamond saw blade used for processing refractory bricks of a high-temperature furnace body; at the same time, it also relates to a manufacturing method of the diamond saw blade. Background technique [0002] At present, for the cutting of high-strength refractory bricks used in high-temperature furnaces, some manufacturers use traditional grinding wheels for smoothing and metal saw blade processing, which is very inefficient; generally large-scale steel factories use diamond saws imported from abroad. The raw materials are expensive and the price is high, and the use of foreign products is not only costly, but also the processing tools are subject to foreign companies, which makes the work progress of domestic steel mills very passive. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a diamond saw blade that can quickly ...
