The hollow shaft is a very critical part of the mill. It bears the entire grinding body and the operating load of the grinding body. It runs continuously under the action of alternating stress. It is the weakest link of the mill body and the most difficult part to control the manufacturing quality. . For this reason, many manufacturers use super-audio frequency induction hardening machines to carry out quenching heat treatment on the hollow shaft, and the effect is good, which meets the needs of the work.
The hollow shaft is quenched and heat-treated by a super-audio frequency induction hardening machine. The sensor is a copy sensor made according to the specifications of the hollow shaft, which can ensure the uniformity of the hollow shaft quenching to the greatest extent, avoid the occurrence of uneven temperature defects, and ensure the hollow shaft. The quenching quality of the shaft makes the surface of the hollow shaft after quenching have a hardened layer of about 2-3mm. It is this layer of hardened layer that greatly improves the hardness, wear resistance and service life of the hollow shaft, which meets the needs of the work.
Our super audio frequency induction hardening machine is a high-tech product produced with advanced technology. It is small in size, light in weight, does not take up too much production space, and can move the working position at any time to facilitate production needs. Even better, it has many advantages such as fast heating speed, good heating effect, long service life, simple operation, safe production, energy saving and environmental protection when quenching and heat treating the hollow shaft.
