Description

Four-way feed horizontal-vertical alternate cutting type cogging mill
Technical Field
The invention belongs to the technical field of steel rolling equipment, and particularly relates to a four-way feed horizontal-vertical alternate cutting type cogging mill.
Background
In the current rolling production technology, the cogging of the billet (i.e. the continuous reduction of the billet section until the billet is beneficial to rolling) is to directly roll the billet heated to the rolling temperature by adopting a relatively large rolling mill, the sectional area of the billet is gradually reduced by multi-pass rolling until the billet sectional area is reduced to meet the condition of entering a finishing mill group, and then the billet enters the finishing mill group and is rolled by the finishing mill group to form the final product. The various related rolling lines of the prior art rolling technologies such as those mentioned in patent nos. 202010042179.2, 201911325629.2, 201610011589.4 are conventional production forms using the above rolling technologies. The defects of the traditional production form are that the equipment of the roughing mill group and the middle mill group has larger overall dimension, heavy equipment weight and high energy consumption, the production line needs larger installation capacity, the occupied area and the used space of the production line are large, the factory construction investment is large, the construction period is long, and in addition, a large amount of spare part consumption and higher daily manual maintenance cost are generated after the rolling production line is put into operation.
Therefore, if the small-section blank can be directly used for rolling the steel products only through the finishing mill group, the equipment investment of more than 60 percent can be directly saved, the using area of more than 50 percent can be saved, the electric energy consumption of the production line can be reduced by more than 70 percent, and a large amount of equipment spare part consumption and manual maintenance cost can be saved. 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.
