Rolling technology for stainless steel wire rod

Abstract

The invention discloses a rolling technology for a stainless steel wire rod. The technology comprises the following technological steps of blank preparation, heating treatment and groove rolling. The stainless steel wire rod is rolled from rough to fine through rough rolling, intermediate rolling and secondary intermediate rolling; rough rolling comprises five rolling steps; according to the first rolling step, corner machining is carried out on a square billet; according to the second rolling step, the blank with the machined corner is machined to be in an oval shape; according to the third rolling step, the oval blank is machined to be in a round shape; according to the fourth rolling step, the round blank is machined to be in an oval shape; according to the fifth rolling step, the oval blank is machined to be in a round shape. Intermediate rolling comprises nine rolling steps; secondary intermediate rolling comprises five rolling steps. According to rough rolling, intermediate rolling and secondary intermediate rolling, the oval blank and the round blank are converted, and finally a semi-finished product with the round section is formed. When pre-finish rolling, finish rolling, spinning, controlled cooling, packaging and groove rolling are carried out, the square billet with the machined corner after the first rolling step is directly transited to be in the oval-round hole type, the deformation degree is even, defects are small, the size of the blank capable of being rolled is diversified, and the range of a rolled-out part is expanded.

Description

technical field

[0001] The invention relates to a stainless steel wire rod rolling process. Background technique

[0002] The current stainless steel wire rod rolling process includes billet preparation, heat treatment, pass rolling, pre-finishing rolling, finishing rolling, spinning, cooling control, and packaging. After multi-pass corner processing, after multi-pass conversion between square and rectangular, it is finally rolled into a round shape. The final spinning deformation is not high, and there are many defects. The billet that can be rolled is single, and the rolled piece Narrow range. Contents of the invention

[0003] The purpose of the present invention is to overcome the defects existing in the prior art and provide a stainless steel wire rod rolling process, which has relatively uniform deformation of the wire rod, reduced defects, diversified sizes of rolled blanks, and expanded range of rolled products.

[0004] To achieve the above object, the technical...
