Product Details

Pit type carbonitriding heat treatment furnace

Brief

Pit type carbonitriding heat treatment furnace is new type and energy-saving batch type furnace,working temperature is 950℃,using the following heat treatment, carburizing, nitriding and carbonitriding, the workpiece is vertically loaded in furnace tank for heating, not easy to deform. Pit type furnace is usually placed under the ground plane in the workshop, also is placed above the ground plane, or ground level fluctuation in each half.

Application field

Mainly used for rod and long axis steel mechanical parts.

Structure

Pit type carbonitriding heat treatment furnace is mainly composed of furnace shell, furnace lining, heating device, muffle tank, loading frame, the furnace cover, and furnace cover lifting mechanism., etc. Furnace body is cylindrical deep well.

Advantages

1.The workpiece is vertically loaded in furnace tank for heating, not easy to deform;

2.Good sealing performance, easy operation and maintain, long working service life.

3.Using advanced protective atmosphere control system, including carbon control instrument and oxygen probe, ensure that the workpiece carbonitriding layer uniform and high precision.
