Abstract

The invention discloses a bell-type heating resistance furnace system comprising two oppositely arranged support frames; a heating cover capable of vertically moving is arranged between the two support frames; and a bearing trolley capable of moving back and forth is arranged below the heating cover. According to the bell-type heating resistance furnace system disclosed by the technical scheme, workpieces are quenched by horizontally entering a quenching tank after being heated, so that the phenomena of nonuniform product hardness, unqualified structure and easily generated cracks caused by overlong transfer time and inconsistent quenching liquid entering time are avoided, and the heat treatment effect and product percent of pass are improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a bell jar type heating resistance furnace system. Background technique [0002] At present, the heat treatment and quenching heating device of heavy industrial long shaft and large rod mainly adopts well type resistance furnace for heating. However, the heating of the pit furnace requires a very high factory building and a deep foundation pit, resulting in high investment and construction costs for the manufacturer. And when using the pit furnace to heat the long shaft rod, the workpiece is vertically suspended in the pit furnace for heating. When the workpiece is heated to temperature and quenched, the workpiece is lifted from top to bottom in the pit furnace. When the workpiece enters the quenching tank for quenching, the workpiece enters the quenching liquid from bottom to top for quenching, so that the long-axis large rod will appear first out of the furnac...
