Quenching and cooling of vacuum quenching furnace

Quenching and cooling of vacuum quenching furnace

The depth of the quenching pool is 1.5 times greater than that of the loading frame, which can ensure that the workpiece is quenched and cooled in the quenching pool. An electric heating tube is used for heating in the quenching pool. And it is automatically controlled by a temperature measuring instrument. The pool has a water inlet to cool the water temperature, and a circulating water pump is installed in the pool to circulate hot water to make the temperature even. Refractory fiber cotton sand sealing knives are embedded around the furnace mouth. After the furnace door is closed, it is closely attached to the insert knife at the furnace mouth to ensure no heat dissipation. The heating element adopts strip-shaped electric heating elements, which are respectively arranged on both sides of the furnace, and the material is 0Cr25AL5 alloy wire, which has a long service life.

Aluminum silicate refractory fiber material for vacuum quenching furnace

The base frame is used for storing furnace parts and is welded by section steel. The furnace door shell is formed by welding steel, and the inner lining is made of high-quality all-fiber structure.

The furnace door and the furnace body are sealed with aluminum silicate refractory fiber material.

The electric stove is equipped with two trolleys. The lifting mechanism is composed of a hoist, a loading frame, a lifting hinge, a rolling wheel, etc. The winch is installed on the side of the base frame, adopts a low-speed ratio reducer, and has a self-locking device, which can ensure that the loading frame stays at any position and decelerates to run, preventing the loading frame from quickly hitting the quenching tank when it is lowered. The loading frame is made of section steel according to user requirements. The lifting device frame adopts steel cable towing.
