Abstract
The utility model discloses a crystallizer copper tube with angle parts cladded with slow-cooling strips, used for metallurgy continuous casting equipment. The crystallizer copper tube comprises a square billet crystallizer copper tube; four outer angle parts of the crystallizer copper tube are cladded with the slow-cooling strips molded by huge thermal resistance materials along an axial direction from the lower side of a board-clamping groove to the middle part of the crystallizer copper tube; inner side faces of the slow-cooling strips are uniformly distributed with inlaid protruding column bodies along the axial direction; and each inlaid protruding column body is respectively in an inlaid fitting with an inlaid blind hole which is arranged on the outer angle part of the crystallizer copper tube. By cladding the slow-cooling strips on the outer angle parts of the square billet crystallizer copper tube, the utility model enlarges thermal resistance of the angle parts, improves cooling uniformity of steel billets molded inside the crystallizer copper tube, thereby avoiding the defects of surface sinking on the angle parts, inner fissures and the like on the steel billets, and guaranteeing steel billet quality.
Description
Technical field
The utility model relates to the crystallizer copper pipe that metallurgical continuous casting equipment is used, and is specifically related to the crystallizer copper pipe that a kind of bight coats the slow cooling bar.
Background technology
Common tubular type square blank crystallizer copper pipe is in being applied to continuous casting production process, because the continuous casting billet part is cooled off by two-dimentional two-sided heat radiation, and face is the single face cooling, so the bight cooling velocity is facial fast, cause the cooling velocity inequality of steel billet in same cross section, when drawing some to the special steel grade of crackle sensitivity, defectives such as nearly corner surface depression, underbead crack often appear in steel billet like this, influence the credit rating of steel billet, also may cause the batch waste product of steel billet when serious.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of and can reduce the cooling velocity in square blank crystallizer copper pipe bight relatively, improves in the steel billet forming process crystallizer copper pipe that in the same cross section bight of cooling uniformity coats the slow cooling bar.
The technical scheme that realizes above-mentioned purpose is: a kind of bight coats the crystallizer copper pipe of slow cooling bar, it includes the square blank crystallizer copper pipe of top band Card trough, below Card trough, be coated with slow cooling bar vertically at four external angles of crystallizer copper pipe by big thermal resistance material moulding to the middle part of crystallizer copper pipe, be evenly distributed with vertically on the medial surface of this slow cooling bar and inlay convex column, respectively inlay convex column and inlay and cooperate with the blind hole of inlaying that is arranged on the crystallizer copper pipe external angle respectively.
Above-mentioned slow cooling bar and convex column preferred rubber forming materials.
The utility model coats the slow cooling bar by four external angles at common square blank crystallizer copper pipe, increased the thermal resistance in bight relatively, the cooling uniformity of steel billet moulding in crystallizer copper pipe is improved, thereby avoid steel billet defectives such as corner surface depression, underbead crack to occur, guarantee the quality of steel billet.
Description of drawings
Fig. 1 is the crystallizer copper pipe front view that this bight coats the slow cooling bar;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the I partial enlarged drawing of Fig. 2.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, the crystallizer copper pipe of this bight coating slow cooling bar includes the square blank crystallizer copper pipe 2 of top band Card trough 1, below Card trough, be coated with slow cooling bar 3 vertically at four external angles of crystallizer copper pipe 2 by big thermal resistance material moulding to the middle part of crystallizer copper pipe, be evenly distributed with vertically on the medial surface of this slow cooling bar 3 and inlay convex column 4, respectively inlay convex column 4 and inlay and cooperate with the blind hole of inlaying that is arranged on the crystallizer copper pipe external angle respectively.
As accompanying drawing 3, place the convex column 4 on slow cooling bar 3 medial surfaces to be fit to adopt the column type cylinder, the setting of this convex column not only can improve the bond strength of slow cooling bar 3 and crystallizer copper pipe 2, and helps further improving the uniformity of crystallizer copper pipe bight heat radiation cooling.
Claims (2)
1. a bight coats the crystallizer copper pipe of slow cooling bar, it includes the square blank crystallizer copper pipe (2) of top band Card trough (1), it is characterized in that: below Card trough, be coated with slow cooling bar (3) vertically by big thermal resistance material moulding to the middle part of crystallizer copper pipe at four external angles of crystallizer copper pipe, be evenly distributed with vertically on the medial surface of this slow cooling bar and inlay convex column (4), respectively inlay convex column and inlay and cooperate with the blind hole of inlaying that is arranged on the crystallizer copper pipe external angle respectively.
