How To Protect Tungsten Carbide Rolls On The Rolling Mill During Production
2. The pressure should be reasonable. Pay attention to the compression ratio between the base metal and the finished product during the rolling process. If the compression ratio is too large, the roll will be overloaded and easy to cause roll ring cracks.
3. The matching method of the roll and the roll shaft is very important, because the roll is brittle and difficult to process, it cannot be connected by a key, but it must be ensured that it cannot slip under the working condition of strong torque, otherwise the roll will be cracked.
4. There must be a proper gap between the upper and lower rolls, and the pressing rolls cannot be used to pursue the negative difference of the steel bars. On the one hand, the longitudinal ribs will be ugly, and on the other hand, the rolls will be easy to crack.
5. Active roll rolling must have excellent technology. During the production process, it must be ensured that the front stage of the roll is not fed smoothly, there is no violent anti-tensile load, and the subsequent stage discharge is natural, and there is no mandatory stretching discharge. It is best Do not use a powered straightening machine, because the linear speed of the straightening machine must be faster than the linear speed of the roll, which will cause the steel bars to damage the roll groove or pass, which shows that there are cracks and drops on both sides of the pass.
6. Finally, the material of the carbide roll itself should be the best.
