High-Precision and High Temperature Box type Resistor Furnace is the national box-type energy-saving cycle operation box furnace, mainly used for high-chromium, high manganese steel pieces, wear-resistant liner quenching, heat treatment and various mechanical parts. The products comply with the China Aviation Industry, the Ministry of military standards, GJB509-88 industry standard box-type furnace.
Structure description:
The shell are welded by steel plate and steel form. the box-type furnace lining material from the ultra-light 0.6g/cm3 energy-saving insulating refractory brick building, there are aluminum silicate fiber insulation in the sandwich, furnace shell and lining silicate insulation between the layers packed powder insulation expansion, electric components using high alloy products 0Cr27Al7Mo2 deviation .Furnace walls and placed in the dormant brick on the bottom, use the best bottom plate put in a piece of silicon carbide stainless steel cladding, and this may prevent the furnace bottom of the workpiece impact. Furnace Door movements through electrical and worm reducer and the drive sprocket chain conducted, and through electromagnetic brake. Furnace Door upper part of a circuit device, when Furnace Door open at the box-type furnace that power supply to ensure operator safety. On top hole with three thermocouples, in the use of thermocouple will be inserted into the furnace, through counters to control the temperature control box furnace temperature and over-temperature protection. To improve temperature uniformity, box-type heating furnace using three districts, in accordance with temperatur wires arrangement law layout heating elements for the heat loss compensation furnace mouth, I District II District III district heating elements of the different layout, furnace insulation in the process of heating and maintaining three districts temperature consistent. Made of silk around the resistivity map all in the form of technical papers should be properly safeguarded for future maintenance replacement. Microcomputer box-type furnace matching three districts procedures automatic temperature control cabinet, the Big Three microcomputer using district heating were conducted on the three high-precision temperature control and automatic operation control of the Furnace Door, mainly for the automatic control and automatic temperature records.
