Description

Sealing structure of box-type tempering furnace

Technical Field

The utility model relates to a seal structure of box tempering furnace belongs to tempering furnace technical field.

Background

The tempering furnace is a common heat treatment device and is generally used for tempering metal parts in air and quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy castings, pistons, aluminum plates and the like. The temperature of the heating furnace is very high, so that the sealing and the pressing of the furnace door become a problem which is very troublesome in the use of various domestic heating furnaces. The most common pressing mechanism for domestic heating furnaces is to press the furnace door frame by utilizing the component force generated by the inclined plane of the furnace door leaning against 1.5-3 degrees. The mechanism has the advantages of simple and easy structure and low price, and is widely used by domestic manufacturers at present. However, the structure has the defects of poor sealing and easy burnout of the fire furnace door frame and the furnace door frame. The local burning loss of the door frame and the furnace door frame can cause more serious fire leakage, thereby forming vicious circle, greatly influencing the uniformity of a temperature field in the furnace, influencing the heating quality of workpieces, and greatly reducing the service life of the furnace door. It is known that foreign heating furnaces do not adopt such a structure.
