Enameled steel plate and production method thereof

Abstract

The invention discloses an enameled steel plate. The enameled steel plate comprises components including, by weight percent, smaller than or equal to 0.05 of C, smaller than or equal to 0.03 of Si, smaller than or equal to 0.40 of Mn, smaller than or equal to 0.020 of P, smaller than or equal to 0.015 of S, and larger than or equal to 0.020 of Alt. The invention further discloses a production method of the enameled steel plate. According to the enameled steel plate and the production method thereof, by optimizing and controlling the component content and the parameter of the rolling technology, the production cost of the obtained enameled steel plate is low, and no precious metal element needs to be added. The defects in the quality aspects such as swelling upheaval, cold crackle, fish scale crackle, scale crackle, pitted bubbles and holes do not exist, the market prospect is wide, and the requirement of social development is met beneficially. The production method of the enameled steel plate is suitable for industrialized production, and the preparation method is simple.

Description

technical field

[0001] The invention relates to the technical field of metallurgical plates, in particular to an enamelled steel plate and a production method thereof. Background technique

[0002] Enamel steel plate is a composite material made of high-quality steel and special functional inorganic non-metallic materials, which are enameled by a new electrostatic dry powder enamelling process and fired at high temperature. The obtained enamel products are widely used in household appliances, subway decoration and other fields due to their advantages of corrosion resistance, easy cleaning and beautiful appearance.

[0003] Enamel steel directly affects the performance of enamelled steel plate. The pearlite in the internal structure of the steel decomposes into free carbon when the sintering temperature is high, which affects the performance and quality of the enamel steel plate. After sintering, the expansion and swelling appear, and the enamel surface appears cold burst, f...
