Problems solved by technology
[0003] At present, there have been some methods to improve the deep drawing performance of cold-rolled base materials for deep drawing. The main method is to solve the problems of wrinkling and cracking of the plate by improving the processing method of deep drawing. Without improving the raw materials for making the plate, it cannot be passed. Improving the deep drawing performance of the cold-rolled base material for deep drawing by improving the steelmaking process

The invention relates to a steelmaking process of a cold-rolled base material for deep drawing. The steelmaking process comprises a feeding process, a slagging process, a blowing process, a tapping process, an argon blowing process and a continuous casting process, so that a desulfurizing agent and a dephosphorizing agent can be added through a feeding device, and thus the sulfur content and the phosphorus content in molten steel are reduced; a removing agent is added through the feeding device, and thus the content of impurities in the pure molten steel is reduced; the purity of the pure molten steel is improved through the adjusting effect of a first slag stopping plug and a second slag stopping plug; and the total amount and speed of blowing argon are controlled and adjusted through anargon blowing device, and thus the bubble density of the pure molten steel meets the preset condition. Therefore, the molten steel smelted by the steelmaking process is stable in chemical components and high in purity, so that the deep drawing performance of the cold-rolled base material for deep drawing can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a steelmaking process of a cold-rolled base material for deep drawing. Background technique [0002] The cold-rolled base material is the hot-rolled plate that is taken to the cold-rolling plant for cold-rolling after hot-rolling. It is the main product of hot-rolled strip steel and provides raw materials for the cold-rolling process. Deep drawing refers to the metal plastic processing method in which the metal sheet is stamped into deep parts on the die of the press. The quality of deep drawing depends on the deep drawing performance of the metal sheet. Therefore, it is particularly important to improve the deep drawing performance of the cold-rolled base material for deep drawing. [0003] At present, there have been some methods to improve the deep drawing performance of cold-rolled base materials for deep drawing. The main method is to solve the problems of wrinkling and ...
