Pit furnace RJ3 series

heat treatmentcarburizingoxidation

Application：forging parts, casted parts,pressure vessel,Train railway,special steel plate,shaft,rotary parts,centrifugal fan impeller Ceramic fiber module has been main insulation materials for the pit type electric resistance furnace of my company, the appearance can be designed into round pit type resistance furnace, or polygon pit type resistance furnace according to customers' requirements . In order to save the workpiece lifting space ,pit type resistance furnace is often installed underground, only the furnace door system is placed on the ground. The furnace can be designed into gas carburizing furnace, gas nitriding furnace, less oxidation furnace type and so on according to the heat treatment process. 2. Structure It consists of furnace body, furnace lining, heating elements, furnace cover, furnace cover lifting mechanism, hot air circulation system (optional), carburizing and nitriding device (optional), intelligent process control system, etc. 3. Features 1).The furnace lining contains brick structure, fiber structure, composite structure and other materials. 2).Product can be configured with hot air circulation system, rapid cooling system. 3).To meet the customers on different heat treatment process, different kinds of furnace atmosphere control system (including carbon control instrument, oxygen probe, electromagnetic valve, etc.) can be figured . 4).The furnace can be designed to be deep pit furnace especially for long axial workpiece.
