Furnace door for heat treatment furnace

Abstract

The invention relates to the accessories of the heat treatment furnace equipment and specifically discloses a furnace door for a heat treatment furnace. The furnace door comprises a furnace door main body, four links, a speed-down motor, a rolling shaft and a rotary disc; a refractory fiber layer is arranged at the inner side of the furnace door body, a lug boss is arranged on the refractory fiber layer, a chain wheel is sleeved on the rolling shaft, and a chain is arranged on the chain wheel; the rolling shaft is arranged at the upper part of the furnace mouth side of the body of the heat treatment furnace, a furnace door frame is arranged at the furnace mouth side of the body of the heat treatment furnace, the rotary disc is arranged at the bottom of the furnace door frame, and the speed-down motor is arranged at the top of the body of the heat treatment furnace; the speed-down motor is axially connected with the rolling shaft by virtue of a belt, the rolling shaft is connected with the four links by virtue of the chain, and the rolling shaft is axially connected with the rotary disc by virtue of the chain; the four links are arranged at the two sides of the furnace door main body, pulleys are further arranged at the two sides of the furnace main body, and slide rails corresponding to the pulleys are arranged on the furnace door frame.

Description

technical field [0001] The invention relates to accessories for heat treatment furnace equipment, in particular to an electric four-link horizontally pressed furnace door for the heat treatment furnace. Background technique [0002] The heat treatment furnace is the key equipment to realize the heat treatment process. Whether the mechanical properties, physical properties, chemical properties and service life of the processed workpiece can achieve the expected effect depends on the performance of the heat treatment furnace used, that is, the uniform temperature performance of the furnace. The furnace uniform temperature of the heat treatment furnace mainly depends on the layout of the furnace door and temperature control area The intelligent control of the mode and temperature system, the sealing of the furnace body, etc., so the sealing of the furnace door of the heat treatment furnace is very important. [0003] When the current furnace door is opened and closed, the refr...

AI Technical Summary

Problems solved by technology

[0003] When the current furnace door is opened and closed, the refractory fibers in the furnace door are often sheared and rubbed, causing the refractory fibers to be easily damaged and have a short life. When the refractory fibers are damaged, the sealing effect of the furnace door will become poor, resulting in The thermal insulation performance is reduced, so that the mechanical properties, physical properties, chemical properties and service life of the processed workpiece cannot reach the expected effect. The solution is to replace the refractory fiber on the furnace door, which wastes artificial and material resources. It takes up production time, affects work efficiency and increases the operating cost of the enterprise
