Abstract

The invention discloses a manufacturing technique and equipment for a high-performance composite roller shaft. The manufacturing technique comprises the steps that a mandril installed in a combined water-cooling crystallizer is integrally heated to 840-1100 DEG C through an induction heater; molten liquid of a working layer of the roller shaft is poured into the mandril, and then the mandril is continued to be heated for 10-50 minutes; a lifting device is stared so as to lift the heater at a certain speed for 5-15 minutes, and the heater is stopped in the position of a heat-insulating ring; and heating is continued for 10-50 minutes, feeding is conducted on a dead head, and after heating is stopped, cooling is conducted for 30 minutes to 24 hours through water. When the composite roller shaft is manufactured through the manufacturing technique, the number of controllable technological parameters is small, the interface of a composite layer is easy to control, the technique is simple, the efficiency is high, the power consumption is low, the cost is low, the composite layer is free of composition segregation, and the service life of the roller shaft is long; the defect of a centrifugation method that structure segregation is prone to occurring is overcome, and the problems of a CPC method and an ESR method that the production technique is complex, and the cost is high are solved.

Description

technical field [0001] The invention belongs to the technical field of metal pressure processing, and in particular relates to a high-performance composite roller shaft manufacturing process and equipment, which are suitable for manufacturing composite rollers in the steel rolling industry. Background technique [0002] Roller parts are widely used in metallurgy, mining, electric power, petrochemical, building materials and other fields. They are bulky and consumable key components of rolling deformation, crushing, grinding and supporting, conveying, guiding and other equipment. The annual consumption is more than 5 million tons, worth 10 million More than 100 million yuan. Shaft parts are the key components of equipment, and the annual consumption is hundreds of billions of yuan. The existing manufacturing process has problems such as high cost, low efficiency, poor quality, and short service life, resulting in huge waste and pollution. [0003] The roll is known as the "...
