Heat-controllable tubular gas heat treatment furnace

Abstract

A heat-controllable tubular gas heat treatment furnace is characterized in that the heat-controllable tubular gas heat treatment furnace comprises a gas furnace (1) and a heat treatment furnace (12), one end of the heat treatment furnace (12) is supported on the gas furnace (1), the other end of the heat treatment furnace (12) is supported on a support (17), a condensation end at the upper ends of gravity assisted heat tubes is positioned in the heat treatment furnace (12) to heat the hearth of the heat treatment furnace (12), and an evaporation end at the lower end of a straight tube type gravity assisted heat tube traverses through the furnace walls of the heat treatment furnace (12) and the gas furnace (1), is positioned in the gas furnace (1) and is used for absorbing heat generated by the gas furnace (1); and the gas furnace (1) and the heat treatment furnace (12) are respectively connected with a ventilation unit for realizing the uniformity of the respective internal temperature. The heat-controllable tubular gas heat treatment furnace has the advantages of simple structure, flexible heat supply mode, utilization of all waste heats, energy saving, environmental protection and simple making process, and can be widely applied in the current industrial production.

Description

technical field [0001] The invention relates to a heat treatment furnace, especially a heat treatment furnace that does not use electric energy, specifically a controllable heat pipe gas heat treatment furnace that can use heat energy generated by gas combustion or industrial waste gas heat energy to heat the heat treatment furnace. Background technique [0002] As we all know, heat treatment is a very important process in the production of metal parts, and modern industrial production has higher and higher requirements for heat treatment efficiency, precise control of heat treatment temperature and energy saving. 70% of the parts in the machinery industry need to be heat treated, 70%-80% of the parts in the automobile and tractor industries need to be heat treated, and 100% of the tools, cutting tools and bearing products need to be heat treated, even if some civilian light industrial metal products are used Most of the service life is also improved by heat treatment. The ...
