Product Description

Product Description

Box-type resistance furnace is an industrial furnace that uses current to heat the electric heating element or heating medium in the furnace to heat workpieces or materials. It is a heating furnace that uses electric current to generate heat energy through resistive materials.

Box-type resistance furnaces are used in the machinery industry for heating before metal forging, metal heat treatment heating, brazing, powder metallurgy sintering, glass ceramic roasting and annealing, low melting point metal melting, sand molding and drying of paint film layers, etc.

Box type is a heating furnace with a box-shaped furnace. The product is fixed during the entire heating process of heating, holding and cooling, and the feeding and discharging are carried out through a single door or trough. Also known as intermittent production furnace.
 

Application fields

Box-type resistance furnaces are mainly used for quenching, normalizing, annealing, aging and heat treatment of various mechanical parts in the automobile manufacturing industry.

Working principle

Box-type resistance furnaces convert electrical energy into heat energy through heating coils or resistance wires, and transfer heat energy through the air in the box.

Box-type resistance furnace is an electric furnace that uses Joule heat generated by current passing through conductors as the heat source.
Box-type resistance furnace uses electricity as the heat source, converts electrical energy into heat energy through electric heating elements, and heats metal in the furnace. The resistance furnace has a high thermal efficiency compared to the flame, which can reach 50-80℅. The thermal system is easy to control, the working conditions are good, and the furnace body has a long life. It is suitable for heating workpieces with strict requirements, but the power consumption is high.
According to the heat transfer mode, box-type resistance furnaces are divided into radiation resistance furnaces and convection resistance furnaces. Radiation resistance furnaces mainly use radiation heat transfer, and the convective heat transfer effect is small; convection resistance furnaces mainly use convective heat transfer, often called air circulation resistance furnaces, which rely on hot air for heating, and the furnace temperature is usually lower than 650°C. .
According to the way of electric heat generation, resistance furnaces are divided into two types: direct heating and indirect heating.
