Compared with prior art, the utility model has the advantages that:
1, production efficiency is high.Setting due to press-roller device of the present invention, pressure roller is pressed in the upper surface of rolling steel billet near the edger roll both sides all the time stably, can effectively prevent steel billet in the rolling on edge process because of the edging roll rollover that open cell type does not cause, realize that single milling train is not needing to change under the prerequisite of roll, realize the rolling of many kinds, save roll changing time, improved production efficiency, reduced production cost.
2, investment cost is low.Setting due to press-roller device of the present invention, the edging roll of anapsid is equivalent to a pair of omnipotent edging roll, greatly improved the utilization rate of every pair of edging roll, not only saved the operation of open cell type on the edging roll body of roll, and reduced the deposit to edging roll, save the spare part expense, also saved the investment cost of the equipment such as lowering or hoisting gear (before becoming roller) of rolling on edge front and back simultaneously.
3, saving energy.Due to the setting of press-roller device of the present invention, saved the lowering or hoisting gear of milling train front and back, shortened the length of production line, make production line more compact, reduced the heat loss of steel billet in the operation of rolling, reduced energy consumption.
