Application

·   HARDUN series pit gas carburizing furnaces are mainly used for carburizing of steel parts to

      increase surface hardness、wear resistance and fatigue resistance.

· It can be used for carburizing of low-carbon steel and alloy steel, and also quenching-and

      tempering of medium–carbon steel.

Product   Feature 

·  Furnace lining of HARDUN series pit gas carburizing furnace is high quality and

    energy saving.

·  There is a sealing fan to increase furnace pressure and temperature uniformity.

·  The carbon atmosphere is even, carburizing speed is high, and carburizing layer is well

     distributed.

·  With novel design of muffle pot, the uniformity of carbon potential and furnace temperature is

      increased.

· We adopt microcomputer to control temperature craft, it is very accurate.

·  Users can choose ordinary or automatic carbon potential control instrument .

·  As for temperature control unit, users can choose home made or imported ones.

·  Users can choose quick cooling system with air.

·  According to customer's requirements, the furnace and hardening oil tank、water tank、

   retarded cooling pot、tempering furnace can make up a production line .

· For  HARDUN series pit gas carburizing furnaces, custom sizes and shapes can be made

     to order.
