Safety high-temperature annealing furnace

Abstract

The invention discloses a safety high-temperature annealing furnace, aiming at overcoming the safety performance problem of an annealing furnace, improving the safety coefficient of the annealing furnace and enhancing the utilization efficiency of heat. In order to achieve the effects, the safety high-temperature annealing furnace comprises a furnace body shell arranged below the ground, a furnace cover is arranged on the top of the furnace body shell, a heating element is distributed at the furnace side, the furnace cover is connected with a hydraulic lifting mechanism, a furnace cover support is profile steel erected on a guide rail combination, a preventive rod opening is formed in the side wall of the furnace body shell, close to the position of the furnace cover, and a ceramic preventive rod is arranged in the preventive rod opening. The safety high-temperature annealing furnace is specially used for metal cables. After the furnace cover is opened, the ceramic preventive rod in the preventive rod opening extends to protect a furnace mouth and prevent people or other articles from accidentally falling into the annealing furnace.

Description

technical field [0001] The invention relates to an annealing furnace used for a wire drawing system, in particular to a safe high-temperature annealing furnace. Background technique [0002] Heat treatment furnaces are divided into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are mainly used for annealing of large carbon steel and alloy steel parts; tempering of surface quenched parts; heat treatment processes such as stress relief annealing and aging of weldments. Heating methods include electric heating, oil, gas, coal, and hot air circulation. For ordinary small and medium-sized enterprises, well-type annealing furnaces are commonly used, such as special annealing furnaces for metal cables, which are used for heat treatment of metals at rated temperatures [0003] However, in the specific use process, the safety of such an annealing furnace still has a little problem. Because the temperature...

[0003] However, in the specific use process, the safety of such an annealing furnace still has a little problem

Because the temperature of the annealing furnace is very high when it is working, it cannot be cooled immediately after the work is completed. At the same time, such high temperature not only affects other processes, but also leads to danger.

Although the strict company system can prevent people from falling into the furnace, the safety factor still needs to be improved

In addition, the annealing furnace after use, on the one hand, the temperature is too high and needs to be cooled down, on the other hand, a lot of heat energy is actually wasted, which is a pity
