Description
Technical field
The invention belongs to field of metallurgical equipment, and in particular to a kind of casting tube type crystallizer.
Background technique
The main body of casting tube type crystallizer is to be arranged with water jacket outside copper pipe by one piece of copper pipe straight forming, cooling water with it is whole
A copper pipe huyashi-chuuka (cold chinese-style noodles) contact.Compared to fourplatemold, casting tube type crystallizer does not have the angle seam between copper sheet, and corner water
Sewing cloth, it is more reasonable to set, more evenly to slab cooling, corner better quality.But the copper pipe of casting tube type crystallizer generally compared with
It is thin, only copper pipe and water jacket are fixed with flange at the top and bottom of crystallizer, prevent the deformation of top and bottom, the middle part of copper pipe
Without being joined with bolts as image of Buddha fourplatemold between water jacket, but due to the height of casting tube type crystallizer compared with
Greatly, it generally in 0.9m or so, therefore is easy to cause in the middle part of copper pipe under ferrostatic pressure, cooling hydrostatic pressure and thermal stress effect
Moderate finite deformation is generated, copper pipe deforms the position of maximum region 0.1m under molten steel liquid level.
Studies have shown that deflection is consequently increased 0.4~1.4mm with the increase of casting tube type crystallizer cross section, pass
Thermal resistance increases by 30%~70%, can significantly affect the heat transfer and solidification behavior of slab, causes localized heat transfer uneven, forms crackle
The defects of, especially slab corner crack.In addition, the abrasion of copper pipe and slab increases after copper pipe deflection increase, copper can be reduced
The service life of pipe.
Summary of the invention
The technical problem to be solved in the present invention is to provide the companies that one kind can effectively reduce the middle part deflection of existing copper pipe
Cast tube type crystallizer.
The technical solution adopted by the present invention to solve the technical problems is: casting tube type crystallizer, including copper pipe and water jacket；
The copper pipe is in rectangle, and side adjacent to each other on copper pipe is connected smoothly by arc sections；The water jacket is set in copper
Guan Shang, and water seam is formed between water jacket and copper pipe；It further include along the outer surface that arc sections are arranged in the short transverse of copper pipe
Copper bar, the outer surface of the copper bar is arcwall face and mutually sticks together with the cooperation of the inner surface of water jacket.
Further, the arc length of the copper bar outer surface is 5~40mm, the outer surface of copper bar and the appearance of copper pipe
The distance between face is 4~10mm.
Further, the height of the copper pipe is H1, the height of the copper bar is H2, 100mm≤H2≤H1-20mm。
Further, the top of the copper bar at least 10mm lower than the top of copper pipe, copper pipe is compared in the bottom of the copper bar
Bottom height at least 10mm.
Further, the copper bar is welded on copper pipe, the side of copper bar and the outer surface of copper pipe pass through circular arc chamfering
It is connected smoothly.
Further, the radius of the circular arc chamfering is 2~5mm.
Further, being provided at least two copper bars in the arc sections, and the copper bar in each arc sections is along copper pipe
Short transverse is spaced apart.
Further, the spacing between adjacent two copper bar in the arc sections is 50~400mm.
Further, the copper bar region be copper pipe middle part reinforcement area, the top in middle part reinforcement area with
It is 80mm the distance between at the top of copper pipe, is 300mm the distance between at the top of the bottom in middle part reinforcement area and copper pipe.
Further, being respectively equipped with top flange and flange in the bottom on the top and bottom of the copper pipe, and pass through top
Portion's flange and flange in the bottom respectively be fixed together at the top and bottom of water jacket.
The beneficial effects of the present invention are: copper is arranged on the arc sections outer surface of copper pipe by the short transverse along copper pipe
On the one hand item can reinforce the structural strength of copper pipe, another aspect copper bar can also be snuggly mated to together with water jacket, therefore energy
The deflection being substantially reduced in the middle part of the copper pipe of the tube type mold produced, and improve the quality and the crystallization of produced continuous casting billet
The service life of device.It is tested under same operating condition, compared with existing casting tube type crystallizer, copper pipe becomes the casting tube type crystallizer
Shape amount reduces 25%~58% (being averagely about 46%), and it is (average to be about that slab corner crack rate reduces 25%~40%
31%), service life increases 29%~62%.
Detailed description of the invention
Fig. 1 is implementation structural schematic diagram of the invention；
Fig. 2 is the partial enlarged view in Fig. 1 at A；
In the figure, it is marked as copper pipe 10, water jacket 20, water stitch 30, copper bar 40.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Referring to figs. 1 and 2, casting tube type crystallizer, including copper pipe 10 and water jacket 20；Copper pipe 10 is in rectangle, and copper
Side adjacent to each other is connected smoothly by arc sections on pipe 10；Water jacket 20 is set on copper pipe 10, and water jacket 20 and copper
Water seam 30 is formed between pipe 10；It further include the copper bar 40 on the outer surface that arc sections are arranged in the short transverse of copper pipe 10,
The outer surface of copper bar 40 is arcwall face and mutually sticks together with the cooperation of the inner surface of water jacket 20.
