Cover type annealing furnace

Abstract

The invention provides a cover type annealing furnace. The cover type annealing furnace comprises an annealing furnace outer cover, an annealing furnace inner cover, a furnace table base, a furnace table fan, a material column and a tray; the annealing furnace outer cover and the annealing furnace inner cover are both mounted at the top of the furnace table base; the furnace table fan is mounted at the bottom of the furnace table base; an output shaft of the furnace table fan penetrates through the furnace table base to fix with a fan impeller; the material column is a hollow column, and is vertically fixed on the furnace table base; the fan impeller is covered in the material column; the tray is annularly wound on the side wall of the material column, and is communicated with the material column; through holes are uniformly formed in the surface of the tray; and a positioning buckle is vertically upwards arranged in the radial direction. The cover type annealing furnace has a more excellent insulation effect, effectively heats castings, facilitates reduction of the heat consumption, and reduces the treatment cost.

Description

technical field [0001] The utility model belongs to the field of heat treatment equipment, in particular to a bell annealing furnace. Background technique [0002] With the rapid development of my country's foundry industry, the competition among casting manufacturers is becoming more and more fierce. Only high-quality and low-consumption castings can be competitive in the market. Heat treatment is one of the important processes that determine the energy consumption of the production process of casting performance. When using a bell annealing furnace, the outer cover is raised during use, and the outer cover is gradually put into it and then lowered. However, the current bell annealing furnace has a poor thermal insulation effect and needs continuous heating, which increases the processing cost and has a fixed effect on the casting. slightly worse. [0003] Therefore, developing a bell annealing furnace capable of solving the above problems is an urgent problem for those skil...
