Abstract
The utility model discloses a crystallizer for casting, which comprises a crystallizer main frame (2) and a crystallizer base (3). A frame (1) is fixed onto an outer ring of the crystallizer main frame (2); an included angle beta in the thickness direction of the crystallizer main frame (2) ranges from 150 degrees to 155 degrees; a circular arc R1 in the thickness direction of the crystallizer main frame (2) is 40mm; and a circular arc R2 of each corner is 20mm. After adopting the structure, the crystallizer not only can improve product yield, but also can reduce damage and faults of hot rolling equipment caused by the shortcomings of layering, warping and the like due to uneven deformation, and has the advantages of simple and reasonable structure, stable and reliable work, small investment and the like.
Description
Technical field
The utility model relates to a kind of non-ferrous metal plate band processing industry, particularly a kind of crystallizer that prevents to produce inhomogeneous deformation in the plate sheet and strip process.
Background technology
At present, the main technique flow process of non-ferrous metal almag strip material processing industry is as follows: make ingot casting by electrolysis aluminium ingot (also claiming virgin aluminium ingot) through melting, batching, semi-continuous casting, again the ingot casting sawing is become fritter, meet the strip section product that various material standards require through milling face, heating, hot rolling, manufacturing procedure such as cold rolling, producing again.When the ingot casting sawing becomes fritter, be wherein, determine the length of sawing according to the desired width of product.And when rolling, the length direction of sawing then becomes the width of final products.Through carrying out hot rolling after the working procedures, in course of hot rolling, when ingot casting when thickness 450mm rolls the sheet metal thickness of 20mm during by casting, the deformation processing rate of hot rolling is generally greater than 95%.According to practical distortion shape and deformation rule: the flow direction of metal is to flow along the distortion of minimum drag direction.This has just produced in the process of big deformation processing rate, and surface metal flows greater than the metal flow of central core.And produced inhomogeneous deformation thus, the result of inhomogeneous deformation be make rolling strip material produce serious layering, warpage in two ends end to end, and then damage equipment reduces the lumber recovery of product.At the problems referred to above, many scientific research institutions, manufacturer and knowledgeable people have carried out R and D, but do not have comparatively ideal way to solve the problems referred to above so far as yet.
Summary of the invention
In order to overcome the shortcoming of above-mentioned existence, change the harm that this inhomogeneous deformation brings, the applicant thinks the essential geometry that changes the ingot casting thickness direction, and the general crystallizer of present domestic design can't satisfy the requirement of correcting this inhomogeneous deformation, need redesign to make novel crystallizer, the purpose of this utility model provides the casting crystallizer that a kind of inhomogeneous deformation amount simple and reasonable, that the hot rolled strip process produces is little, input is economized.
The technical scheme that its technical problem that solves the utility model adopts, it comprises crystallizer body frame (), crystallizer base, it is characterized in that: the outer ring of described crystallizer body frame is fixed with frame, and the angle of crystallizer body frame thickness direction is β, and the span of β is 150 ° to 155 °.
The angle β of described crystallizer body frame thickness direction is 152 °.
The circular arc R 1 of described crystallizer body frame thickness direction angle is 40mm, and the circular arc R 2 of corner is 20mm.
After adopting said structure, the utility model has following advantage and effect: by improving the mechanical strength of crystallizer, the angle β of thickness direction changes 152 ° into from original 163 °, the circular arc R 1 of thickness direction angle is reduced into 40mm by original 150mm, the circular arc R 2 of corner is reduced into 20mm by original 35mm, changes the ingot casting section configuration.Through facts have proved, with identical material, identical working modulus and processing conditions, rolling operation on same hot-rolling mill, effect is obvious, the caused layering of inhomogeneous deformation, warpage length are changed into 150mm～250mm by 1200 original～1500mm, thereby have reached the effect of correcting and reduce inhomogeneous deformation; The 2nd, can be when the rolling aluminum magnesium alloy plate and belt, improve the lumber recovery of product, can reduce the equipment of hot rolling that causes because of defectives such as layering that inhomogeneous deformation produces, warpages and damage and fault.
