Problems solved by technology

[0004] However, the structural design of most existing heat treatment furnaces for seamless steel pipes is relatively complicated, and the heat treatment process is single. Usually, one heat treatment furnace can only be used to treat one heat treatment process, so that the economic utilization rate of the heat treatment furnace is not high and cannot meet the requirements of production. Different properties of seamless steel pipes

Abstract

The invention relates to the technical field of heat treatment furnaces, particularly a combustible-gas heat treatment furnace for producing seamless steel tubes, which is provided with a thermal insulation furnace shell, wherein the top of the thermal insulation furnace shell is provided with an inlet; the inlet is provided with a sealed vacuum furnace door; an alloy vacuum chamber prepared from circulating drum tubes is arranged in the inner cavity of the thermal insulation furnace shell; a cavity formed between the thermal insulation furnace shell and alloy vacuum chamber is a combustion chamber; the left and right sides of the thermal insulation furnace shell are respectively provided with a circulating motor; and the output end of each circulating motor is provided with a circulating fan positioned in the combustion chamber. The combustible-gas heat treatment furnace for producing seamless steel tubes has the advantages of compact structure, high universality and high economic utilization ratio, and can be used for producing seamless steel tubes with different structures and performance requirements.

Description

technical field [0001] The invention relates to the technical field of heat treatment furnaces, in particular to a gas-fired heat treatment furnace for producing seamless steel pipes. Background technique [0002] Seamless steel pipes have a hollow cross-section and are widely used as pipes for transporting fluids, such as transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipes are lighter in weight under the same flexural and torsional strength; at the same time, seamless steel pipes are also widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes , automobile transmission shaft, bicycle frame and steel scaffolding used in construction, etc., the material utilization rate is high, the manufacturing process is simple, and the processing time is reduced. [0003] It is precisely because of the particularity of the use of seamless steel pipes that heat t...
