Embodiment Construction

[0041] The invention provides a glass-lined steel plate with excellent anti-scale explosion performance and a manufacturing method thereof. The mass percentages of chemical components in the steel are: C: 0.011% to 0.060%, Si: 0.08% to 0.20%, and Mn: 0.60% to 1.8%, P≤0.035%, S: 0.010%~0.045%, N: 0.003%~0.009%, Ti: 0.035%~0.20%, Cr: 0.05%~0.25%, Als: 0.005%~0.050%, Ti / C: 1.5 to 3.5, and the rest are iron and unavoidable impurities. The continuous casting slab smelted according to the above composition ratio is heated to 1180-1250°C, and two-stage rolling is adopted. The rolling temperature in the rough rolling stage is ≥1100°C; 840 ~ 900 ℃, cumulative deformation ≥ 70%. After rolling, the steel plate is air-cooled or water-cooled to 600°C and slowly cooled in the pit.

Abstract

The invention provides a glass-lined steel plate with excellent anti-scale explosion performance and a manufacturing method thereof. The mass percentages of chemical components in the steel are: C: 0.011% to 0.060%, Si: 0.08% to 0.20%, and Mn: 0.60% to 1.8%, P≤0.025%, S: 0.010%~0.045%, N: 0.003%~0.009%, Ti: 0.035%~0.20%, Cr: 0.05%~0.25%, Als: 0.005%~0.050%, Ti / C: 1.5 to 3.5, and the rest are iron and unavoidable impurities. The continuous casting slab smelted according to the above composition ratio is heated to 1180-1250°C, and two-stage rolling is adopted. The rolling temperature in the rough rolling stage is ≥1100°C; 840 ~ 900 ℃, cumulative deformation ≥ 70%. After rolling, the steel plate is air-cooled or water-cooled to 600°C and slowly cooled in a pit. The obtained steel plate has excellent anti-scale explosion performance.

Description

technical field [0001] The invention relates to a glass-lined steel plate and a production method thereof, in particular to a glass-lined steel plate with excellent anti-scale explosion performance and a production method thereof. Background technique [0002] The so-called glass-lined refers to the coating of glass-lined enamel with high silicon content on the surface of metal (steel) and firing at high temperature to make the enamel adhere to the surface of the steel plate. Therefore, the glass-lined steel plate has the dual advantages of glass-like chemical stability and metal strength. It is precisely because of the unique properties of glass-lined steel plates that glass-lined steel plates are widely used in chemical, pharmaceutical, dye, pesticide, organic synthesis, petroleum, food manufacturing and defense industries to replace expensive stainless steel and non-ferrous metals. [0003] As the main manufacturing material of glass-lined equipment, the performance of s...
