Pre pumping box type vacuum furnace
Pre vacuum box vacuum furnace and known as the horizontal vacuum annealing furnace, box type vacuum furnace, box type protective atmosphere furnace, heat treatment furnace, vacuum, vacuum atmosphere box type furnace, vacuum box atmosphere furnace, box type electric furnace, box type muffle furnace, box type vacuum dryer, box type resistance furnace, vacuum quenching furnace, copper box type light vacuum annealing furnace.
This equipment is mainly used in mechanical parts and mould materials workpieces in a protective atmosphere without or little oxidation of bright quenching or annealing and copper, copper pieces of bright annealing heat treatment.
Derived atmosphere protection furnace. To furnace infusion with methanol as organic liquid, the main organic liquid, after pyrolysis to form a protective atmosphere for carbon steel, alloy, alloy steel workpieces with little or no oxidative quenching heating and bright annealing with protective atmosphere box type furnace. Can be used for carburizing, nitriding and other purposes. In particular, annealing, applicable to all sorts of small parts, small parts, spring, mould spring, mould for less without oxidation and decarburization heat treatment.
Pre pumping box type vacuum furnace
Vacuum heat treatment is the combination of vacuum technology and heat treatment technology of new type heat treatment technology, heat treatment pre pumped vacuum box vacuum furnace is lower than the atmosphere of a big pressure, including low vacuum, moderate vacuum, high vacuum and ultra high vacuum, vacuum heat treatment actual also belong to the controlled atmosphere heat treatment. Vacuum heat treatment refers to the heat treatment process of full and partial in the vacuum state of that vacuum heat treatment can achieve almost all conventional heat treatment involved in the heat treatment process and heat treatment quality can be greatly improved. With the conventional heat treatment compared to vacuum heat treatment at the same time, realization of no oxidation, no decarburization and carburization, can remove the phosphorus particles from the workpiece surface, and degreasing gas removal effect, so as to achieve the bright surface purification effect.
Pre pumped vacuum box type furnace is mainly composed of a furnace shell, lining, a furnace tank, furnace cover, a heating element, a temperature sensor and vacuum component part.
Furnace shell with steel plate, angle steel welding, steel plate is made from high-quality A3 steel lining the quality of high purity aluminum silicate refractory fiber folded block, fixed with heat resistant steel anchor, to avoid erosion of the airflow of the fiber. The whole fiber lining can ensure the shell outer wall temperature in the furnace up small, lining storage less heat, warming fast, obvious energy saving effect, long service life. The electric heating element is made of 0Cr27AL7Mo2 high resistance band, and is installed on the furnace wall refractory fiber folding block. Tank furnace is made of austenitic heat resistant steel, furnace cover is arranged at the edge of the vacuum pipe, furnace tank on the other side is provided with a pipeline, a stainless steel ball valve control N2 into pipeline with valve, pneumatic valve and vent valve, vacuum table. The parts to be processed are placed in the furnace.
The furnace can be welded with the imported material SUS310S heat resistant steel plate, in order to increase the strength. The furnace cover is provided with a vacuum pressure gauge, a thermocouple seat, a safety valve and an exhaust pipe. A high vacuum butterfly valve is arranged on the exhaust pipe. Between the furnace and the furnace cover, the silicone strip is sealed with heat resistant and temperature resistant. Another use of forced water to ensure that the temperature is too high to ensure that the temperature is too high. And a sealed thermocouple temperature measurement base for measuring the temperature in the furnace tank.
