[0026] Taking the preparation of ZGM110 type (output: 5-8t / h, grinding disc diameter: 1100mm, rotation speed: 50r / min, power: 110KW) coal mill lining as an example, the invention will be further explained in conjunction with the drawings. The output of ZGM110 type :5~8t / h, grinding disc diameter: 1100mm, speed: 50r / min, power: 110KW.
[0027] A preparation method of tungsten carbide ceramic / heat-resistant alloy-based heat-resistant and wear-resistant composite material includes the following steps:
[0028] Step 1. Cut the tungsten carbide ceramic waste (1) into a composite reinforcement of the required shape and size, select YG8 tungsten carbide ceramic waste, and process it into a tungsten carbide ceramic with a size of Φ5mm×8mm through wire cutting Reinforcement, sandblasting after degreasing, and finally cleaning;
[0029] Step 2: Weld an iron nail (2) to one end of the tungsten carbide ceramic reinforcement treated in step 1, using a vacuum brazing process, and the brazing mate...
