Embodiment Construction
[0019] Below in conjunction with specific embodiment, this case is described in further detail.
[0020] This case involves a preparation method of a new type of cost-effective granite universal saw blade, the steps are as follows:
[0021] 1) Preparation materials:
[0022] a. Prepare the carcass material: the carcass material is mainly composed of 45-55% Fe-Cu-Sn pre-alloyed powder and 45-55% Fe-Cu pre-alloyed powder. The particle size of the two pre-alloyed powders is 300 -400 mesh; weigh the above two pre-alloyed powders according to the weight ratio and mix evenly to obtain the carcass material;
[0023] Wherein the ratio of each trace element of Fe-Cu-Sn pre-alloy powder is 80-83% Fe, 15-17% Cu, 2-3% Sn; the ratio of each trace element of Fe-Cu pre-alloy powder is 80% -85% Fe, 15-20% Cu;
[0024] b. Prepare diamond: mix diamonds with a particle size of 35 / 40-50 / 60 evenly;
[0025] c. Prepare the intermediate layer blank: the intermediate layer blank is composed of 10...
