Heat treatment equipment for stainless steel pipe

Abstract

The invention discloses heat treatment equipment for a stainless steel pipe and relates to equipment for improving the quality of a metal product. The equipment comprises ammonia decomposing equipmentand a heat treatment device, wherein a pressurizing pump is arranged between the ammonia decomposing equipment and the heat treatment device. Because the pressurizing pump is arranged between the ammonia decomposing equipment and the heat treatment device, an ammonia decomposing gas can be pressurized to a certain value so as to meet the working requirement, and the invention overcomes the defectof explosion hazard of a hydrogen compressor, reduces the maintaining cost and the production cost, prolongs the service life of the heat treatment equipment and has higher practicability.

Description

technical field [0001] The invention relates to a device for improving the quality of metal products, in particular to a heat treatment device for metal products. Background technique [0002] In order to keep the outer surface of the stainless steel pipe bright and free of oxidation after annealing, the hydrogen nitrogen atmosphere generated by the ammonia decomposition equipment is often used as a protective atmosphere during the heat treatment process to minimize the oxidation or decarburization heat treatment process, but in the process of use, It is necessary to increase the pressure of the ammonia decomposition gas to meet the needs of the work. Now the hydrogen compressor is commonly used to pressurize it. Because the hydrogen compressor has high requirements for explosion-proof safety, the investment cost and operating cost are increased. In terms of safety and maintenance caused a lot of trouble. Contents of the invention [0003] The purpose of the present inven...
