Trolley furnace belongs to gap type variable temperature furnace, which is mainly used for steel ingot heating or workpiece heat treatment before forging, so its furnace type can be divided into trolley type heating furnace and trolley type heat treatment furnace. The furnace consists of a hearth, a movable trolley and a furnace door.
Bell - type furnace is used for bright annealing and heat treatment of workpiece equipment, belongs to the intermittent variable temperature furnace, furnace temperature in 650 ~ 1100 ℃, according to the provisions of the heating system changes with time. According to the loading of bell-type furnace, the furnace is divided into two categories: square bell-type furnace and circular bell-type furnace. The heat source of bell-type furnace is mostly gas, followed by electricity and light oil. Generally consist of an outer cov, an inner cover and a furnace platform, wherein that combustion device is mostly arranged on the out cover, the outer cover is provided with a heat insulation layer, and a workpiece is generally arranged in the inner cover for heating and cooling.
Well cementite furnace is a new type of energy-saving periodic operation type heat treatment furnace, which is mainly used for gas carburizing of steel parts and is suitable for heat treatment of rod and long shaft parts. The structure of the well furnace is as follows: the furnace body is a cylindrical deep well, and the workpiece is vertically loaded into the furnace by a special crane for heating.
High temperature mesh belt type heat treatment furnace is generally protected by muffle mesh belt will realize the continuous conveying of parts in the furnace sintering furnace. It is mainly use for sintering pow metallurgy products and reduction of metal powder and presintering, sinter or heat treatment process of electronic products in protective atmosphere or air, and is suitable for heat treatment of small parts.
