Description
Technical Field
The invention belongs to the technical field of steel rolling equipment, and particularly relates to a steel billet cutting type cogging mill.
Background
In the current steel rolling production technology, the cogging of the steel billet (i.e. the continuous reduction of the section of the steel billet until the billet is favorable for rolling) is to directly roll the steel billet heated to the steel rolling temperature by a relatively large rolling mill, the sectional area of the steel billet is gradually reduced by multi-pass rolling until the sectional area of the steel billet is reduced to meet the condition of entering a finishing mill group, and then the steel billet enters the finishing mill group and is rolled by the finishing mill group to form the final steel product. The prior art rolling technology, such as the rolling lines mentioned in patent numbers 202010042179.2, 201911325629.2 and 201610011589.4, are conventional production forms using the above rolling technology. The disadvantages of this conventional production form are the large overall dimensions of the roughing mill group and the intermediate mill group, the heavy weight of the equipment, the high energy consumption, the large installation capacity required for the production line, the large floor area and space occupied by the production line, the large construction investment in the rolling mill, the long construction period, and in addition, the large spare part consumption and the high daily labor maintenance cost after the rolling mill production line is put into operation.
Therefore, if the small-section billet can be directly used for rolling the steel products only through the finishing mill group, on the one hand, the equipment investment is directly saved by more than 60%, the using area is saved by more than 50%, the electric energy consumption of the production line is reduced by more than 70%, and on the other hand, a large amount of equipment spare part consumption and manual maintenance cost are saved for the capacity of the same scale. However, the acquisition of small-section billets, particularly low-cost small-section billets, is a major difficulty faced by the current technology, and the production of small-section billets capable of being directly finish rolled by using a continuous casting machine is not feasible in the current environment due to the difficulties in the aspects of technology, cost and safety, but the small-section billets can be easily obtained by using a reciprocating cogging mill or a continuous rolling unit consisting of a roughing mill and a medium rolling mill, but the high production cost of the small-section billets weakens the competitiveness of final products to a certain extent.
