The invention discloses a production method of low-
silicon and low-carbon deep
punching / drawing steel, bottom-blowing
argon is performed in the whole process of converter
smelting, and a single
slag / double
slag technique is adopted to pour out the dephosphorized
slag, high-basicity slag is produced in later period, the dualistic basicity of final slag R is more than 3.5, the terminal temperature of
molten steel is 1620 DEG C to 1650 DEG C, and tapping ( P ) is less than 0.012 percent. The
molten steel is refined by adopting low-
silicon and low-carbon high-basicity reductive slag in a LF furnace refining
station, thus to manufacture reductive slag for desulphurisation, and the ( Al ) in the
molten steel is less than 0.005 percent. The molten steel refined by the LF furnace is vacuum-treated by a RH
vacuum furnace, the carbon and the
silicon in the molten steel is circularly removed, the molten steel is continuously casted into a
casting blank through a CSP sheet bar conticaster, the
casting blank is sent into CSP sheet bar heat
continuous rolling mill and rolled into a coiled sheet after being heated in a roller
hearth soaking furnace, a
hot rolled coiled sheet is coldrolled into cold rolled coiled sheet through a cold tandem mill or a single mill after being acidwashed, and leveled through a leveling
machine after being annealed by a cover furnace, and a leveling divided coil is stretched and divided. The production method has the advantages that the production cost of the working procedure is saved, the consumption of the
refractory consumption of the converter is reduced, the equipment investment is saved, the process of the production technique is steady and smooth, the n value of the cold rolled plate is bigger than 0.23, the r value thereof is bigger than 2.1, and the deep
punching performance and the
extensibility are good.
