Embodiment Construction

[0021] see figure 1 , the composition of a patterned steel plate provided by the embodiment of the present invention is by weight percentage: C: 0.020-0.065%, Si≤0.40%, Mn: 0.20-0.70%, P≤0.025%, S≤0.015%, Als: 0.02 ~0.06%, N≤0.010%, the rest is iron and unavoidable impurities.

[0022] Description of the main alloy elements of the present invention:

[0023]C is the most economical and effective element for improving steel strength, but excessive C content will deteriorate the weldability of the steel. The weather-resistant patterned steel plate of the present invention must have good weldability, and the C content of the present invention is designed to be 0.040-0.075%.

[0024] Si is beneficial to improve the strength and yield point of steel, and is also an important element affecting the surface quality of hot-rolled strip steel. In order to ensure the good surface quality of the steel plate, the Si content of the present invention is designed to be 0.25-0.45%.

Abstract

The invention discloses a checkered steel plate and a production method thereof, and belongs to the technical field of steel rolling. The checkered steel plate is characterized in that the checkered steel plate comprises the components of, by weight, 0.020-0.065% of C, no more than 0.40% of Si, 0.20-0.70% of Mn, no more than 0.025% of P, no more than 0.015% of S, 0.02-0.06% of Als, no more than 0.010% of N, and the balance iron and unavoidable impurities. According to the checkered steel plate and the production method thereof, the demands of batched stable production of thin specification checkered steel plates can be met.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a patterned steel plate and a production method thereof. Background technique [0002] Checkered steel plate has good anti-skid and wear resistance, and is easy to clean, so it is widely used in construction, shipbuilding, transportation, machinery manufacturing and other fields. Due to the particularity of the patterned steel plate, it is very different from other steel types in production, and there are special requirements for the quality of the plate shape, the integrity of the pattern, and the height of the bean. [0003] However, in the process of producing patterned steel plates in the prior art, there are problems such as pattern rolls falling off the pattern resulting in incomplete patterns (scrap steel accidents occur in severe cases), coiling flat coils, and uneven pattern bean heights after leveling, resulting in a high rate of quality change and rejection of pa...
