Mill roll is an important part of the rolling mill, and we use the pressure that mill roll is rolling to generate to rolling steel. In the course of work, the mill roll should withstand the huge friction. Therefore, we have high requirements to the mill roll's quality. How to improve its quality? We can improve the hardness and wear resistance and other aspects to do it. And high frequency induction heating equipment can meet your requirements.
Mill roll's quenching depth is usually 3-5mm, and this depth determines that it can only use the equipment for quenching heat treatment. After hardening, the surface of the mill roll has hicker toughness region under the hard layer with good compression of internal stress, so that the anti-fatigue and breaking capacity are higher.
This equipment has the advantages of small volume, light weight, high efficiency, excellent processing quality and environmental protection. And it is gradually replacing the out of the coal-fired stoves, gas stoves, oil stoves and ordinary resistance furnace, which is a new generation of metal heating equipment. Better is the machine can not only be used for surface quenching of metal parts, but also can be used for parts of the hole quenching, which is that the traditional heat treatment equipment can not be achieved.
