What are the technical indicators of the characteristics of the tungsten carbide corrugated roller? The process of the tungsten carbide corrugated roller is different from that of the traditional corrugated roller. First of all, the hardness of the front matrix heat treatment is different, the precision of the spray front tooth type is high, and the grinding is completed on the automatic numerical control
1, corrugated roller 50CrMo alloy steel forging;
2, corrugated roller basic body medium frequency quenching hardness >HRC58 tooth height deviation ≤0.025mm
3, tungsten carbide coating thickness 0.06 -- 0.08 mm; Top runout tolerance ≤0.025mm
4, tungsten carbide coating microhardness > HV1250-1400 tooth thickness deviation ≤0.03mm
5, binding strength >75MPa tooth profile deviation ±0.02mm
6, visible metallographic porosity <1% tooth side axis equal deviation ≤0.03mm
7, the optimized design of economic corrugated tooth top cylindrical bus straightness ≤0.02mm tooth deviation ±20 "in the middle and high roller height deviation of the middle and high value of ±5%
