Company Introduction

We are a comprehensive furnace supplier of heat treatment furnaces. 
We can supply the following products: box type furnace, bogie hearth furnace, hot air circulation oven,well type furnace, hood type furnace, tube type furnace, mesh belt furnace, continuous type roller type, continuous roller hearth furnace, tiltable roller furnace, push rod furnace, steel strip furnace, aluminum alloy quenching furnace, pit type heat treatment furnace,aging furnace, brazing furnace, laboratory furnace, crucible furnace, and aluminum melting and holding furnace.
The pit type heat treatment furnace treats the workpieces under protective atmosphere, control atmosphere, or

vacuum status and with energy mediums such as electricity, natural gas, coal gas, industrial fuel oil and others


Applicationat treat furnace 

The pit type heat treatment furnace is mainly used for tempering heat treatment of middle and small size metal parts and alloy parts.

The working temperature is less than 650℃. The furnace is equipped with ventilator device and air guide system.

The pit type heat treat furnace adopts SCR and PID control to ensure high control accuracy

and stable performance.

electrical control system

Temperature control: the furnace is PID control which adopts Shanghai Guolong intelligent temperature

controller to control the temperature.

The heating control loop has over-temperature alarm and send sound-light alarm when the heating zone is over-temperature.

The SCR, AC connector, intermediate relay, stroke switch, operating switch, button and signal indicate light adopt

Delixi Brand which has good accuracy and long service life.

Electrical control cabinet: the cabinet is made according to industrial standard.

The connection line from the control cabinet to the main circuit of the furnace body

is insulated with copper coreand all wire numbers are clearly printed.



Installation and maintenance


Install the furnace according to the drawing. Check the heating element whether there is any

phase break, circuit break and short circuit. Test whether the insulation resistance of the heating

element is within the specified range.


Check whether all wiring is loose phenomenon Regularly; Check the stroke switch regularly to

prevent the furnace from being damaged due to the improper action.


Furnace working conditions:

1) The average monthly humidity in the area is no more than 90%;

2) No explosive hazard, no corrosive gas or electric dust;

3) No obvious vibration or turbulence; heavy surface slope is not higher than 5℃;

4) The control cabinet surface should keep clean;

5) Check whether the instrument is working correctly regularly;
