Externally heat furnace nitrate salt bath furnace

Externally heat furnace nitrate salt bath salt bath furnace is a common one of containing the high temperature salt bath salt bath furnace, salt bath furnace temperature, nitrate furnace, salt bath furnace, salt bath hardening furnace, the crucible salt bath furnace , bath crucible furnace, no transformer salt bath furnace, electrode salt bath heaters. Externally heated furnace with molten nitrate liquid medium workpiece, such as nitrate class, bases, oils and low melting point metals and alloys, nitrate furnace heating the workpiece, heating speed, less oxidation and decarbonization. Suitable for railway locomotives, ball mill liner, Ball, Crusher hammerhead Obey body wear-resistant materials, all kinds of metal machinery parts non-oxidizing heating, tempering heating, isothermal quenching, hardening, isothermal quenching and other processes and a variety of chemical treatment.

Nitrate furnace externally heated by a furnace bath heaters, stainless steel crucible, electric components and automatic temperature control cabinet composition, the use of nitrate were parts quenching, tempering heating temperature quenching and other processes, liquid chemical heat treatment furnace body welded from steel and steel plate, cold-rolled sheet steel stove surface, lining using energy-saving ultra-light high-intensity firebrick, dissecting home silicate fiber, filled with insulation, insulation powder expansive between the lining and the furnace shell, the whole structure standard energy-saving lining, high temperature resistance wire using thicker diameter resistance wire wound into a spiral according to the average temperature Busi law, placed on the lining of the dormant silk brick, put silk brick front upturned using 20 ° anti-out silk brick, resistance wire is not easy to fall out. Heat-resistant crucible made of stainless steel plate welded tight. In the crucible installed by stirring motor side, in the composition of the porous diversion holes at the bottom of the crucible, the salt solution by mixing system quickly cycle up and down churn, reach any point within the salt solution temperature uniform. Nitrate furnace by automatic temperature control electric cabinet with the use of automatic thermostat allows any process within a very short time rapidly cooled to a temperature isothermal hardening required quenching the workpiece.

According to the operating temperature of the furnace, usually used as sodium chloride, potassium chloride, barium chloride, sodium cyanide, potassium cyanide, sodium nitrate, potassium nitrate and other salts as the heating medium. Salt bath furnace heating speed, temperature uniformity. The workpiece is always in Heated salt solution, the surface and the workpiece with a layer of salt film came out, it is possible to prevent surface oxidation and decarbonization. Salt bath furnaces can be used for carbon steel, alloy steel, tool steel, tool steel and aluminum alloy quenching, annealing, tempering, cyanide, aging heat treatment, heating can also be used when less oxidized steel precision forging heating. Salt bath furnace heating medium vapor harmful, must ventilation.
