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.

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 edge of the steel substrate to obtain a diamond saw blade.

[0021] When the diamond saw blade of the present invention is used, the diamond saw blade is assembled on the main shaft of the motor. After the motor is changed speed, the diamond saw blade is driven to rotate at a high speed. When the diamond saw blade rotates, the alloy cutter bit cuts into the furnace body brick and the furnace body brick. The material is much harder than metal, which can quickly wear away the alloy and expose the diamond particles. Diamond is much harder than the furnace brick. The diamond particles can quickly cut the furnace brick into debris and follow the high-speed rotating saw. At the same time, the diamond particles prevent the furnace body brick from further abrading the alloy cutter head. The furnace body brick has a lateral feed motion relative to the main shaft. The saw blade continuously cuts the furnace body brick, thus realizing the saw blade cutting furnace body. brick.
