Box type tempering furnace is a national standard cycle operation box furnace, the top of the furnace installed with a hot air internal circulation fan, mainly for alloy steel products, various metal parts of the tempering heat treatment, and aluminum alloy, copper solid melting, annealing, aging and other light alloy heat treatment.

Structural features:

The outer shell of box type tempering furnace is welded by national standard steel plate and section steel. The lining is made of ultra-light weight and high-aluminum energy-saving insulation brick and combined with aluminum silicate fiber cotton composite lining for insulation.The electric heating elements of box tempering furnace are designed for long life, high temperature resistance and high tolerance of 0Cr25Al5, which are arranged on both sides of the furnace and the bottom of the furnace.The door of the furnace is lifted by electric or hydraulic pressure. Small box tempering furnace can also use the hand-cranked furnace door. When the door is opened, the circuit breaker protection device stops the electric heating.Microcomputer temperature control system is adopted to control the tempering process with high precision, and the whole process of tempering heat treatment from the furnace to the furnace is completed automatically.
