Heat treatment furnce that equip closeness style salt bathtub to all

摘要

To the subject innovation relates to a gas to the carburizing heat treatment (爐) having a closed salt bath integrally, the heated workpiece with the heating furnace 10 for heating the product (workpiece) to heat treatment quenching (quenching) to be used in industrial and it consists of a one-piece closing the salt bath (20) for, by eliminating the problems associated to the contact with an external air in the process of entering the bath 20 is heated workpiece salt, inhibiting defects and increase the efficiency of the heat treatment than that placed the object as to obtain a quality product, the proximity configured integrally with the heating chamber 10 and the salt bath 20, and consists of a closed all of the heating chamber 10, and a salt bath (20) , configure the salt bath 110, a gas passage also the atmospheric gas to be filled in is passed into the 20 salt bath 20, an atmosphere of, the opening and closing door heating chamber (10) a formation (100) therebetween, and a salt bath 20, so as to restore the gas pressure inside the Is integrally configure a gas pressure control device 300 is provided with a combustion device (310), and a salt bath (20) salt and a heating chamber 10 by configuring the discharge gate 200 to the rear tub 20 is fully enclosed configuration and completely solve the problem of oxidation during processing due process embraces the processed tonghagi the discharge door (200) to the heat treatment conditions would have to have an effect, so as to obtain an excellent product.
