Warm rolling process of stainless steel profile

Abstract

The invention discloses a warm rolling process of a stainless steel profile. The warm rolling process of the stainless steel profile specifically comprises the following steps that a material passes through the space between two beryllium copper wheels, a bolt is rotated, adjustment is carried out on the distance between the two beryllium copper wheels according to the production requirement of the material, the beryllium copper wheels are driven to rotate while the material moves, a copper electric brush in contact with the outer circular surfaces of the beryllium copper wheels is connected with a power supply to form a complete loop, and the material between two contacts is heated; and extruding and deforming are carried out on the material through four rollers, water mist is sprayed out through four water mist nozzles, the sprayed water mist is directionally and accurately sprayed to the outer circle faces of the rollers for cooling, air cooling is carried out on the outer circle faces of the rollers through high-pressure air, the water mist on the outer circle faces of the rollers is blow-dried and deposited into water stains, cooling is carried out on the rollers, the outer circle faces of the rollers are dried, the steps are repeated, and controlling is carried out on the temperature of the rollers. According to the warm rolling process of the stainless steel profile, the material deformation resistance is reduced, the material processing pass is reduced, the production cost is reduced, temperature control over the rollers is controlled, and the stability of roller gaps is kept.

Description

technical field [0001] The invention relates to the technical field of austenitic stainless processing, in particular to a warm rolling process for stainless steel profiles. Background technique [0002] Cold working technology is a commonly used processing technology for austenitic stainless steel, which is often used to control the dimensions, structure and mechanical properties of austenitic stainless steel profiles. Austenitic stainless steel (304, 316, etc.) is a metastable supersaturated solid solution at room temperature. It will undergo deformation-induced martensitic transformation under a certain amount of deformation at room temperature, thereby increasing the deformation resistance of the material and increasing the difficulty of material deformation. , making it difficult to process large amounts of deformation. Continued processing must be annealed, increasing the rolling process (drawing distance), increasing production costs. The maximum temperature of aust...

Problems solved by technology

[0003] The purpose of the present invention is to provide a warm rolling process for stainless steel profiles, which solves the following problems: in the traditional warm rolling process, austenitic stainless steel is prone to deformation-induced martensitic transformation during the deformation process, and the deformation resistance of the material is large. The deformation is difficult; the traditional warm rolling process cannot realize the temperature control of the rolls and cannot maintain the stability of the roll gap
