Pilot scale production method of low-carbon Fe-Mn-Al-Si series TWIP (Twining Induced Plasticity) steel

Abstract

The invention provides a pilot scale production method of low-carbon Fe-Mn-Al-Si series TWIP (Twining Induced Plasticity) steel, mainly comprising two technical processes of smelting and rolling the TWIP steel, wherein a smelting link in the pilot scale production of the TWIP steel is finished by a combined smelting manner of a 0.5-ton non-vacuum induction furnace and a 2.5-ton electro-slag refining furnace. The TWIP steel is produced by the combined smelting manner of the 0.5-ton non-vacuum induction furnace and the 2.5-ton electro-slag refining furnace and the manner is basically confirms to an accrual large production condition; the conventional situation of utilizing a 10-Kg experiment furnace to smelt the TWIP steel is changed and an industrial progress of the TWIP steel is propelled; and smelting and rolling technical parameters in the pilot scale production are provided.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and relates to a steel smelting process, in particular to a pilot-scale production method of low-carbon Fe-Mn-Al-Si series TWIP steel. Background technique [0002] According to the general production process of iron and steel, TWIP steel can be prepared by the technical route of smelting → blanking → hot rolling → cold rolling. However, in the research on the production process of TWIP steel, first, the research and reports on smelting are the least. Generally, a small amount of experimental steel is prepared in the laboratory for research purposes, and there is a lack of smelting process and parameters for large-scale production of TWIP steel; There are also few related studies on the hot rolling process, and there is a lack of hot and cold rolling process control methods to achieve the target thickness. Contents of the invention [0003] The purpose of the present invention is to ove...
