Equipment inspection: Before starting the furnace, a comprehensive inspection should be carried out on the equipment to check whether there are tools or other conductive substances in the electrical control box. If there are forgotten workpieces in the furnace, they should be removed in time. In case of loosening, the safety shield must be complete and effective. Special personnel should be responsible for the inspection of electrical appliances and instruments. Only when it is confirmed that there are no hidden dangers in the equipment can the furnace be allowed to work.Mine pressure plate vacuum hardening Furnace start-up: adjust the temperature control indicator number of the temperature control instrument to the position required by the process, then turn on the main power switch of the equipment, turn on the instrument and the heating furnace switch, and the Hongda box-type resistance furnace starts to heat up to the process temperature. After the heating furnace is raised to the process temperature, the temperature shall be measured and calibrated according to the requirements of the temperature calibration technical regulations. When adjusting the instrument temperature, pay attention to: surface temperature = furnace temperature - correction value.Hardenability and Vacuum Heat Treatment of Carburized Steel Furnace charging: According to the structural characteristics of the parts and the size of the batch, the amount of furnace charging varies. The number of furnaces is determined according to the size of the effective heating zone.Low alloy wear-resistant steel and its vacuum heat treatment process Out of the oven: It can be out of the oven after fully insulated according to the process requirements. Pay attention to cut off the power supply of the heater when operating out of the furnace, and remove the parts in the furnace to prevent accidents such as burns.Application of Vacuum Heat Treatment in Fastener Manufacturing
