Abstract

The utility model relates to an arrangement way of a rough milling double-frame vertical roller mill, a vertical roller mill A and a vertical roller mill B are continuously configured in front of an inlet of a horizontal roller rough mill, the side surface of an outlet of the vertical roller mill A, the side surface of the inlet of the vertical roller mill B, the side surface of the outlet of the vertical roller mill B and the side surface of the inlet of the horizontal roller rough mill are combined together through attachment bolts and taper keys, and the two vertical roller mills and the horizontal roller rough mill form a compact type continuous rolling structure. The arrangement way has reasonable arrangement and can carry out centering rolling through double-frame vertical rollers, achieve the purpose of rectifying the lateral flexure of a plate blank, greatly simplify the production process and effectively improve the production efficiency and the product quality.

Description

The arrangement of roughing two-shipper frame vertical miller

Technical field

The utility model relates to a kind of equipment arrangement mode, particularly relates to a kind of arrangement of roughing two-shipper frame vertical miller.

Background technology

In recent years,, simplified production technology greatly, reduced energy consumption, improved product quality and production efficiency along with continuously casting and continuously rolling technology develops rapidly.For realizing being connected on the width between continuous casting and the hot rolling, improve the integrated level of continuous casting and steel rolling, transferring wide to slab when rolling is one of effective measures of taking, but the frequent adjustment of the width of plate slab of continuous casting and rolling then is unusual distinct issues in the restriction production.

At present, the wide technology of accent relatively more commonly used is that the SP forcing press is transferred the wide and wide technology of the rolling accent of edger roll.The SP forcing press is transferred wide comparing with edger roll, owing to do not have the restriction of bite condition, and asynchronous region length is big, so the wide ability of the accent of SP forcing press is big, transfers wide efficient height.But the condition of work of large lateral pressure power makes the SP forcing press be in work under the higher load condition continuously, and there was a mechanical failure often to cause the critical piece unbalance stress, becomes the big continuously bottleneck of producing of restriction, and SP transfers the big and maintenance cost height of wide forcing press investment.

And the vertical miller main limitation is that the slab breadth adjusting quantity is little, and when lateral pressure amount was big, the subject matter of being brought was that the slab cross section occurs than towser bone shape, and the tongue of slab head, afterbody (or fish tail) is defective in the certain-length scope.But at the thicker rolling sequence of slab, by increasing the vertical rolling edge passage, setting rational edger roll lateral pressure amount, can reduce tongue (or fish tail) defect level of slab dog bone shape and slab head, afterbody, reach and improve the slab flat shape, improve the purpose of lumber recovery.Prior art is only considered from the angle of full passage rolling production, can not realize big breadth adjusting quantity and the effect that improves slab quality.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of arrangement of roughing two-shipper frame vertical miller reasonable in design is provided.

In order to address the above problem, the utility model by the following technical solutions:

The arrangement of roughing two-shipper frame vertical miller, before horizontal roller roughing mill inlet, dispose vertical miller A and two milling trains of vertical miller B continuously, vertical miller A outlet side all puts together on by attachment bolt and wedge key with horizontal roller roughing mill inlet side with vertical miller B inlet side, vertical miller B outlet side, and two vertical millers and horizontal roller roughing mill form close-coupled tandem rolling structure.

Compared with prior art, the beneficial effects of the utility model are:

The utility model is from improving the angle of breadth adjusting quantity and slab quality, set up edger roll in the rolling strange passage of roughing, because of roughing mill is a reversable mill, rolling strange passage antithesis passage is many, so strange passage increases edger roll, the slab of the antithesis passage to increase edger roll transfers wide ability strong, and it is rolling by two-shipper frame edger roll centering, can reach the effect of correcting the slab lateral bending, simplify production technology greatly, effectively improve production efficiency and product quality.

Fig. 2 is a structural configuration schematic diagram of the present utility model;

Fig. 3 is that slab of the present utility model is transferred wide schematic diagram.

The specific embodiment

The arrangement of roughing two-shipper frame vertical miller, as shown in Figure 1, before horizontal roller roughing mill 4 inlets, dispose vertical miller A1 and two milling trains of vertical miller B3 continuously, vertical miller A1 outlet side all puts together on by attachment bolt 5 and wedge key 2 with horizontal roller roughing mill 4 inlet sides with vertical miller B3 inlet side, vertical miller B3 outlet side, and two vertical millers and horizontal roller roughing mill 4 form close-coupled tandem rolling structures.

In the strange passage operation of rolling of roughing, as Fig. 2, shown in Figure 3, after the edger roll A7 side pressure of slab 6 in vertical miller A1 was rolling, the edger roll B8 side pressure that enters in the vertical miller B3 was rolling, and the horizontal roller 9 that enters at last in the horizontal roller roughing mill 4 is rolling; In the roughing idol passage operation of rolling, edger roll A7 and edger roll B8 open, and are off position.As shown in Figure 3, adopt arrangement of the present utility model, realized that slab 6 transfers wide purpose continuously in strange passage, utilize the two-shipper frame edger roll centering rolling simultaneously, correction slab lateral bending has improved the breadth adjusting quantity and the product quality of slab 6 greatly.

Claims

1. the arrangement of roughing two-shipper frame vertical miller, it is characterized in that, before horizontal roller roughing mill inlet, dispose vertical miller A and two milling trains of vertical miller B continuously, vertical miller A outlet side all puts together on by attachment bolt and wedge key with horizontal roller roughing mill inlet side with vertical miller B inlet side, vertical miller B outlet side, and two vertical millers and horizontal roller roughing mill form close-coupled tandem rolling structure.
