Product Description

The products are operated by a pre vacuum vacuum atmosphere protection. When the furnace is pumped to a certain vacuum level, the furnace is filled with high purity nitrogen or carburizing atmosphere to protect and heat, so as to achieve the goal of no oxidation heating. Because of the use of mixing fan, the furnace has a high uniformity of furnace temperature. The equipment is mainly used for the quenching of mechanical parts and bright annealing of silicon steel sheet and copper material. In order to improve the production efficiency, the user can choose a more than one pot of work.


1.the design of the structure is reasonable, the furnace temperature is uniform and the temperature difference between up and down in the working area is small, and it is especially suitable for the heating and heat treatment of the shaft type long workpiece.

2.using energy-saving furnace lining, fast heating, small loss of air furnace, more than 20% of the old product.

3.furnace cover is open and integral two, the workpiece can be hooked in the furnace or hooked out of the furnace. It is convenient for users to choose according to different needs.

4.The control system can be equipped with conventional control instruments or instruments controlled by microprocessor programs as required.

5.when the process is needed, the protection atmosphere can be put into the furnace to achieve less oxidation heating.

6.each product is equipped with safety interlock and overtemperature protection device, and the operation is reliable and safe.

7.different well heating furnaces, tempering furnaces, quenching tanks and cleaning machines can be selected to form a well type heat treatment furnace production line, and expand the scope and production capacity of the furnace.

PS:Our company can provide customized design according to user requirements.


How to use it

Pit type gas nitriding furnace is mainly used for the gas nitriding of carbon steel parts, die quenching and other heat treatment. The equipment is equipped with a drop device and can also be treated with gas nitrocarburizing (soft nitriding). When no ammonia gas and drip device are used, it can be used as a general well type tempering furnace.
