Problems solved by technology

At present, all enamelled steel for subway decoration in China uses cold-rolled enamelled steel, but the production process of cold-rolled enameled plate is complicated, the production efficiency is low, and the manufacturing cost is high, and there is no hot-rolled enameled steel as its substitute on the market
[0003] The Chinese invention patent application with the publication number CN201310548310.2 discloses a hot-rolled thin plate enameled steel with a yield strength of 330 MPa and its manufacturing method, and the Chinese invention patent application with the publication number CN200510047758.1 discloses a hot-rolled double-sided enameled steel With steel plates and their manufacturing methods, the deep drawing performance of the steel plate is not considered in their design, and the deep drawing performance index is not mentioned in the performance of the steel plate, and the steel of this strength level can no longer adapt to and meet the requirements of the current subway enamel.

Abstract

The invention discloses sheet enamel steel for subway decoration and a production method thereof. The thickness of the sheet enamel steel is 1.0 to 2.0mm, wherein the sheet enamel steel comprises the following chemical components in percentage by weight: 0.001 to 0.003 percent of C, less than or equal to 0.10 percent of Si, 0.05 to 0.10 percent of Mn, less than or equal to 0.010 percent of P, less than or equal to 0.005 percent of S, 0.01 to 0.02 percent of Als, 0.20 to 0.25 percent of Ti, 0.010 to 0.020 percent of N and the balance of Fe and inevitable impurities. The production method of the sheet enamel steel for the subway decoration comprises the following steps: carrying out desulfurization on molten iron, combined blowing on the top and bottom of a converter, continuously casting plate blanks, soaking through a soaking pit furnace, hot continuous rolling, controlled rolling and controlled cooling, reeling, washing with acid, detecting quality, processing and forming, shot blasting, washing with alkaline, spraying enamel and firing enamel. Through the hot rolled enamel steel, the excellent cooperation of high strength and high deep-drawing property is achieved; the enamel steel is liable to form and weld, low in production cost, high in efficiency and wide in application prospect.

Description

technical field [0001] The invention relates to the field of enamelled steel manufacturing, in particular to a thin-plate enameled steel for subway decoration and a manufacturing method thereof. Background technique [0002] With the rapid development of the national economy and the continuous expansion of the urban area, the subway has become the best means of transportation to solve urban congestion, and has been put into use in many cities in our country. With the construction of subways in major cities across the country, subways and subway stations need a large amount of colored enamel steel as facade decoration materials. At the same time, enamelled steel is a non-combustible material, safe and fireproof, which greatly improves the safety factor of the subway. At present, all enamelled steel for subway decoration in China uses cold-rolled enamelled steel, but the production process of cold-rolled enameled plate is complicated, the production efficiency is low, and the...
