Abstract

The invention relates to a production method of glassed steel, belongs to the technical field of production of cold-rolled plates and strips, and provides the production method of glassed steel. The production method comprises the steps of casting molten steel into a billet, and carrying out hot rolling, acid pickling and cover annealing, so as to obtain glassed steel, wherein the annealing temperature of cover annealing is 690 DEG C to 730 DEG C. Through adoption of the production method, glassed steel with good fish scaling resistance and mechanical properties can be obtained even though alloy elements are not added and production is carried out with low carbon aluminum killed steel with low cost, and glassed steel has good cost decreasing and benefit increasing capabilities and market potentials.

Description

Technical field [0001] The invention relates to a production method of enamel steel, and belongs to the technical field of cold-rolled strip production. Background technique [0002] The enamel product is a composite material made by melting and sintering the electrodeless oxide paint (enamel) on the surface of the enamel steel substrate. It has wear resistance, corrosion resistance, high temperature resistance, easy washing, non-toxic and sanitary cleaning And other characteristics, so it is widely used in the manufacture of household utensils, sanitary ware, water heater tanks, chemical reaction tanks and architectural decorative panels. The enamel steel plate needs to meet the mechanical forming and processing performance required by the enamel product, and has good adhesion to the enamel, without defects such as scales, pinholes, and bubbles. At present, the application of enamel products continues to expand, and the quality requirements for enamel steel are becoming more an...
