The Roll Material of the Universal Continuous Rolling Mill for Ribbed Reinforcing Steel Bar
Rolls used in the rolling process of ribbed reinforcing steel bar in a universal continuous rolling mill are one of the most important components of the entire production line, and the selection of rolls is an important measure to improve product quality and line speed. This article briefly introduces the roll material of the universal continuous rolling mill for ribbed reinforcing steel bar.
Rolls used in the universal continuous rolling mill for ribbed reinforcing steel bar operate under high stress and high speed, and the workpiece is a solid material, so the roll material must have the following characteristics:
First, the roll material should have a certain strength and wear resistance. It is generally required that the roll material can withstand resistance to bending stress, wear can be abrasion-resistant with rollers running in opposite directions, and can have excellent hardness when subjected to extrusion in the cross direction.
Second, the roll material should have good thermal performance.
Rolls used in the universal continuous rolling mill for ribbed reinforcing steel bar work at high processing temperatures and high rolling speeds. The roll material has poor thermal conductivity. The surface of the roll material has a high temperature while the inner part of the roll material has a low temperature. However, a large temperature difference between the surface and the inner part of the roll material will cause thermal fatigue cracking; therefore, the roll material should have good thermal conductivity and high thermal stability.
Third, the roll material should have good metallurgical performance.
Rolls used in the universal continuous rolling mill for ribbed reinforcing steel bar work at high temperatures for a long time. The roll material needs to have good metallurgical performance and can withstand the high temperatures. In addition, due to the rolling contact between the roll and the roll, it is necessary to select a roll material with a large elastic modulus.
In conclusion, roll material with these characteristics needs be selected for universal continuous rolling mill for ribbed reinforcing steel bar. The roll material should have good strength and wear resistance, thermal performance and metallurgical performance. Only in this way can it provide a better guarantee for the production process.
