Abstract
The invention discloses low-carbon steel and a manufacturing method thereof. The low-carbon steel comprises the following components of, in percentage by weight, 0.010-0.060% of C, 0.05-0.5% of Mn, 0.01-0.08% of Al, less than or equal to 0.06% of limiting element, namely Si, less than or equal to 0.03% of P, less than or equal to 0.01% of S, less than or equal to N, and the balance Fe. According to the low-carbon steel and the manufacturing method thereof, the technical problems of high energy consumption, low steel plate yield and a high yield ratio in the prior art are solved, so that the technical effects of reducing the energy consumption and the yield ratio and improving the yield of the steel plate are realized.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to a low-carbon steel and a manufacturing method thereof. Background technique [0002] Low-carbon aluminum-killed steel is a common carbon steel, which is widely used in hardware, home appliances, automobiles, construction and other industries due to its low production cost and excellent formability. In order to obtain good formability, it is necessary to ensure that the low-carbon steel plate has a high degree of purity, and at the same time ensure a reasonable whole-process manufacturing process. [0003] At present, low-carbon steel is mainly rolled in the conventional austenite zone in the conventional hot rolling production line, which has the problems of high energy consumption in the production process, low steel plate yield and high yield ratio. Contents of the invention [0004] By providing a low-carbon steel and its manufacturing method, the present invention so...
