Abstract
The utility model discloses a novel continuous cast slab and a cutting gun for cutting the same, which belong to the field of ferrous metallurgy and are used for reducing a 'tongue' and a 'fishtail' produced after rolling the continuous cast slab. The horizontal projection of the novel continuous cast slab is approximately rectangular, wherein one side of the head part of the novel continuous cast slab has a concave curved surface while one side of a tail part has a convex curved surface; and the horizontal projection of a guide rail of the cutting gun has an accordant shape with the head part or the tail part of the novel continuous cast slab. The defects of the 'tongue' on the head part and the 'fishtail' on the tail part of a steel plate caused by metal flow in a continuous cast slab rolling process is compensated in advance, so that top crops and end crops brought by the defects of the 'tongue' on the head part and the 'fishtail' on the tail part are reduced and the yield is increased.
Description
Technical field
The utility model relates to the novel continuous casting steel billet in a kind of Ferrous Metallurgy field and cuts the cutting gun of this continuous casting steel billet.
Background technology
Continuous casting steel billet all is cut into rectangular bloom at present, the continuous casting steel billet of this shape rolls the back and forms " tongue ", forms " fish tail " at the steel plate afterbody in steel plate head, this " tongue " and " fish tail " must batch or cutting plate before excise, head, the tail of excision become waste product, the influence roll the back lumber recovery.
The utility model content
The purpose of this utility model is to overcome the prior art defective, a kind of novel continuous casting steel billet is provided and cuts the cutting gun of this continuous casting steel billet, with reduce that continuous casting steel billet rolls that the back produces " tongue " and " fish tail ".
The technical solution of the utility model is achieved in that novel continuous casting steel billet, and floor projection is shaped as approximate rectangular, and it is, on one side this continuous casting steel billet head has the curved surface of indent, on one side afterbody has the curved surface of evagination.
Preferably, the curved surface of described indent and the curved surface of evagination are to be the circular arc of symmetry with the width centreline, circular arc and continuous casting steel billet head or afterbody intersection point on one side apart from continuous casting steel billet two back gauges be width of plate slab 0-1/3 doubly, radius be width of plate slab 1/10-10 doubly.
A kind of cutting gun that cuts this novel continuous casting steel billet comprises cutting gun body and cutting gun guide rail, and it is that the floor projection shape of described cutting gun guide rail is consistent with the shape of this novel continuous casting steel billet head or afterbody.
The utility model cuts into the continuous casting steel billet head on one side the curved surface of indent, afterbody cuts into the curved surface of evagination on one side, steel plate head " tongue " and afterbody " fish tail " defective that continuous casting steel billet causes owing to metal flow have been compensated in advance in the operation of rolling, thereby reduced crop and back-end crop that head " tongue " and afterbody " fish tail " defective are brought, improved lumber recovery.

Fig. 2 is the utility model continuous casting steel billet schematic diagram.
Fig. 3 is the utility model cutting gun schematic diagram.
Among the figure, 1-" tongue "; 2-" fish tail "; The curved surface of 3-indent; The curved surface of 4-evagination; 5-cutting gun body; 6-cutting gun guide rail
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As Fig. 2, shown in Figure 3, novel continuous casting steel billet, floor projection is shaped as approximate rectangular, this continuous casting steel billet is symmetry with the width centreline, on one side head has the curved surface 3 of indent, on one side afterbody has the curved surface 4 of evagination, the curved surface 3 of described indent and the curved surface of evagination 4 are circular arc, wherein d=0～1/3W; R=1/10W～10W.A kind of cutting gun that cuts this novel continuous casting steel billet comprises cutting gun body 5 and cutting gun guide rail 6, and the floor projection shape of described cutting gun guide rail 6 is consistent with the shape of this novel continuous casting steel billet head or afterbody.
The curved surface 4 of evagination also can be according to different steel grades and different roll design ovalisation or cubic curve types, to compensate steel plate head " tongue " and afterbody " fish tail " defective that metal flow causes in the operation of rolling on one side for the curved surface 3 of head one side indent and afterbody.
Because the continuous casting billet of each steel mill's slab caster casting of the whole nation at present all is cut into rectangle, form " tongue " 1, form " fish tail " 2 in steel plate head after this continuous casting billet hot rolling at the steel plate afterbody, crop and back-end crop that 200mm～500mm generally will be arranged, adopt the utility model continuous casting steel billet and cutting gun, crop, back-end crop loss are reduced to 0～100mm, have effectively improved and have rolled the back lumber recovery.
