Abstract
The utility model provides an intermediate billet of a plate with a moderate thickness. According to the intermediate billet of the plate with the moderate thickness, the cross section of the intermediate billet is shuttle-shaped, the intermediate billet is composed of a middle section and slope sections, the slope sections are arranged on two sides of the middle section and are symmetrical, and the thickness of the middle section and the thickness of the slope section arranged on two sides are gradually decreased from the middle section to the outside. According to an MAS method and a rolling method of 'dog bone', a conventional steel plate is thin in the middle and thick on the two sides, due to the fact that the shape of the intermediate billet is changed, by means of adoption of the shuttle-shaped intermediate billet which is thick in the middle and thin on two sides, 'forked tail' of the head and 'forked tail' of the tail can be eliminated, the shape of the head of the rolled steel plate is effectively improved, the shape of the head of the steel plate is nearly in a flat and straight state, and the rolling yield and the qualified rate of the ultrathin ultra-wide steel plate can be greatly improved.
Description
Technical field
The utility model belongs to rolling blank field, and it is rolling to relate in particular to a kind of employing MAS(dog bone) the intermediate blank base shape of the rolling plate of moderate thickness of method.
Background technique
At present, the 5500mm heavy and medium plate mill has advanced oil hydraulic cylinder dynamic control technology mostly, can realize the PVPC(plane shape) controlled rolling, be that MAS(dog bone is rolling) method, by dynamic roll gap control, realize the blank intermediate thin, the shape that two is thick solves width rectangle problem pregnant and ligulate end to end.
Yet, find in the production practices process that during than steel plate, the head of steel plate is not ligulate at rolling big broadening, but swallow-tail form, during especially rolling 6mm steel plate, serious accident such as cause that easily Steel Plate Guide Drill backplate and steel plate break, very harmful.Because when original employings MAS controls, employing be the thick what is called in sectional shape intermediate thin, two " dog bone " shape intermediate blank, this can aggravate the generation of this type of defective, has directly influenced up-to-standard rate and the productivity of steel plate.
Summary of the invention
The utility model aims to provide a kind of can effectively the improvement and rolls the swallowtail shape end to end of steel plate afterwards, thereby improves the plate of moderate thickness intermediate blank of plate quality up-to-standard rate and productivity.
For this reason, the solution taked of the utility model is:
A kind of plate of moderate thickness intermediate blank is characterized in that, the intermediate blank shape of cross section is " shuttle " shape, is made up of intermediate section and monosymmetric slope section, and intermediate section is thick, the slope section thickness of both sides is outwards successively decreased gradually by intermediate section.
Described sloped sides section shape and measure-alike, direction is opposite.
The utility model is by the following technical solutions:
Owing to adopted reverse thinking, change the thick intermediate blank shape in steel plate intermediate thin, both sides conventional in MAS method and " dog bone " rolling, by adopting thick middle, the thin intermediate blank shape in both sides, thereby can eliminate " dovetail " end to end, effectively improve the nose shape that rolls the back steel plate, make the nose shape of steel plate near straightened condition, greatly improve rolling productivity and the up-to-standard rate of ultra-thin ultra-wide steel plate.
Description of drawings
Fig. 1 is plate of moderate thickness intermediate blank shape of cross section schematic representation.
Among the figure: intermediate section 1, slope section 2.
Embodiment
As seen from Figure 1, the shape of cross section of the utility model plate of moderate thickness intermediate blank is " shuttle " shape of usefulness of weaving cotton cloth, form by three sections altogether, namely formed by the slope section of receiving in the intermediate section 1 of uniform thickness and the bilateral symmetry 2, the thickness of the slope section 2 of the thick both sides of intermediate section 1 thickness is then outwards successively decreased gradually by intermediate section 1, and the shape of sloped sides section 2 and measure-alike, but opposite, the equal microcephaly of direction outwardly.
Claims (2)
1. a plate of moderate thickness intermediate blank is characterized in that, the intermediate blank shape of cross section is " shuttle " shape, is made up of intermediate section and monosymmetric slope section, and intermediate section is thick, the slope section thickness of both sides is outwards successively decreased gradually by intermediate section.
2. plate of moderate thickness intermediate blank according to claim 1 is characterized in that, described sloped sides section shape and measure-alike, and direction is opposite.
