The roll mold process produced by the company is as follows:
The first step is to add appropriate processing according to the size of the workpiece, and the cutting bar will be cut according to the ratio of the roll lower material size 3: 2-2.5 (forging ratio)；
In the second step, the raw material is heated to 850 ° C to 1000 ° C for forging the raw material, repeatedly forging to the designated amount of the designated material (the workpiece will be repeatedly heated, forged 2-4 times) After the forging, the organization is more tetabed, so that the workpiece improves wear resistance in use, and then heats up to 780 ° C and 830 ° C after surgery for 72 hours；
In the third step, the machine is roughly processed, and the shape, inner hole, hole lathe cuts, the shape, and the shape of the drawings are left in the drawing, and the logo is processed in the designated position；
In the fourth step, quenching, after filling the workpiece to the quenching furnace, gradually warming up to 930-980 °, physically cooling, the hardness of the workpiece is still unstable, and the low temperature tempering will be turned to the standard；
In the fifth step, the hardness detection is used to detect the hardness of the workpiece (58 ° -62 °), and the roll is finished after the hardness is reached, and the finishing includes planar finishing, inner hole finishing, well-finishing。
In order to ensure product quality, every step of processing is striving for fine, professional quality inspectors control each process, return to customers most assured, the most satisfied product!
