Example Embodiment

[0019] Such as figure 1 , figure 2 As shown, the diamond saw blade of the present invention is composed of a steel substrate 1 and an alloy bit 2 impregnated with diamond particles 3, wherein the alloy bit 2 is composed of the following components by weight: 15 grams of tungsten powder and 25 grams of cobalt powder , 45 grams of copper powder, 15 grams of tin powder, 25 grams of iron powder, the purity of the above metal powder is 99.65%.

[0020] The production method of the present invention is as follows: 15 grams of tungsten powder with a purity of 99.65%, 25 grams of cobalt powder, 45 grams of copper powder, 15 grams of tin powder, 25 grams of iron powder and diamond particles are fully mixed and put into the mold together. Inside, heated at a temperature of 850°C, and the hot pressing pressure is 350kgf / cm 2 , At 4 tons / cm 2 It is formed under the pressure of a high pressure to obtain an alloy cutter head, and finally the alloy cutter head is brazed on the outer peripheral ...

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 ...
