Abstract

The invention provides an online control method for continuous casting of a small square billet through dynamic soft press and heavy press. The method comprises the steps that a casting temperature field is tracked and calculated in real time; a pulling-straightening roller conducting soft press and the press degree of the pulling-straightening roller conducting soft press are primarily determined; the position of the solidification tail end is determined; a pulling-straightening roller conducting soft press and heavy press and the press degree of the pulling-straightening roller conducting soft press and heavy press are determined; the pulling-straightening roller conducting soft press and heavy press and the press degree of the pulling-straightening roller conducting soft press and heavy press are transmitted to an automatic roller gap control system, so that the press degree of online soft press and the press degree of online heavy press of each pulling-straightening roller are controlled remotely. The press degree of online soft press and the press degree of online heavy press of the pulling-straightening rollers are controlled online, and therefore the internal quality problems such as center segregation, loosening and shrinkage of a continuous casting slab can be effectively solved, the press efficiency is improved, and the press effect is stabilized.

Description

technical field [0001] The invention relates to the field of continuous casting, and more specifically, relates to an on-line control method for dynamic soft reduction and heavy reduction of billet continuous casting. Background technique [0002] In the billet continuous casting process, such as figure 1 As shown, the molten steel passes through the crystallizer 3 from the ladle 1 and the tundish 2 to form a cast slab 100 with the outer shell solidified and the center as the molten steel after being cooled and crystallized once, and is pulled out from the lower mouth of the mold 3, and the cast slab 100 forms a bend in the mold 3. Moon side 30. After the cast slab 100 is pulled out from the lower mouth of the crystallizer, after secondary cooling, after being straightened by the stretching and straightening rolls (note that only a part of the stretching and straightening rolls are shown in the figure), it passes through the pre-cutting roller table to reach the hot cutting...
