Box-type resistance furnace operating procedures, Box-type resistance furnace operating procedures
 
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

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

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
