Quick cooling structure of large high-temperature resistance furnace

Abstract

The invention discloses a quick cooling structure of a large high-temperature resistance furnace. The quick cooling structure comprises a freezing tower, at least two vacuum stop valves and a high-temperature pipeline fan, wherein the freezing tower, the high-temperature pipeline fan and the large high-temperature resistance furnace are sequentially communicated through pipes to form a closed loop, at least one vacuum stop valve is arranged on the pipe between the freezing tower and the large high-temperature resistance furnace, and at least one vacuum stop valve is arranged on the pipe between the high-temperature pipeline fan and the large high-temperature resistance furnace. The problem that at present, the large high-temperature resistance furnace is too long in temperature reduction time and accordingly influences a workpiece or a material production period and hinders improvement of enterprises' capacity is solved by means of the quick cooling structure of the large high-temperature resistance furnace.

Description

technical field [0001] The invention relates to a rapid cooling structure, in particular to a rapid cooling structure of a large high-temperature resistance furnace. Background technique [0002] The resistance furnace is a device that uses electric current to heat the electric heating element or heating medium in the furnace, thereby heating the workpiece or material and performing related processes. As a common heating equipment, resistance furnace has been widely used in industry and experiment. [0003] In the prior art, the cooling of the resistance furnace basically adopts natural cooling or double-layer water cooling on the furnace wall, and the cooling time is relatively long, especially for large-scale high-temperature resistance furnaces. However, natural cooling takes nearly 100 hours. Even if it is a resistance furnace with a double-layer water-cooling structure on the furnace wall, due to the heat insulation effect of the insulation material in the furnace, the...
