Introduction of Pit-type Tempering Furnace

Pit-type tempering furnace is a type of steel and steel plate welded into the furnace, the main purpose for general metal parts in the air for tempering and aluminum alloy die casting, piston, aluminum plate and other light alloy parts quenching, annealing, aging heat treatment.

Structure:

Pit-type tempering furnace structure, the shell is made of steel plate and steel made of cylindrical furnace body. The inner surface of the furnace cover is made of stainless steel plate. The lining of the furnace is made of energy-saving microporous refractory heat preservation bricks. Furnace lining and shell sandwich aluminum silicate fiber cotton insulation, gap filled with expanded insulation powder. Resistance wire using 0Cr25Al5 high-resistance alloy wire wound into a spiral installed in the furnace chamber on the shelving wire brick. Stainless steel charging basket is placed in the furnace chamber. The lid of the furnace is lifted and lowered by a manual lever. In order to make the workpiece uniform heating, installed in the furnace cover with heat-resistant stainless steel shaft and wind blade made of hot air circulation fan, the workpiece in the heating process, the hot air in the tempering furnace up and down circulation to ensure uniform heating of the workpiece. In order to ensure that the operation of the lifting mechanism near the installation of limit switches, this switch and tempering furnace control cabinet power interlock, the furnace cover is closed (when working) on the power supply. When the furnace cover is opened, the limit switch cuts off the control power supply, so the power supply of the heating element is cut off at the same time to ensure the operation. Pit-type tempering furnace factory supporting automatic temperature control cabinet, thermocouple.

Use:

Pit-type tempering furnace is an energy-saving cycle operation type tempering furnace for use in long shafts, connecting rods, rigging and other suspended heating type workpieces and general metal parts in the air for tempering, but also for aluminum alloy die castings, pistons, aluminum plates and other light alloy parts quenching, annealing, aging heat treatment.
