Abstract
The utility model discloses a cone crystallizer diversion water jacket, comprising a crystallizer copper pipe and a diversion water jacket housed outside the crystallizer copper pipe, wherein a longitudinal cross section of the diversion water jacket is in a cone arced shape and the crystallizer copper pipe in the cone arced shaped diversion water jacket is an isodiametric arc pipe, thus a water gap between the cone arced shaped diversion water jacket and the crystallizer copper pipe is a cone arced shaped gap, the cone arced shaped diversion water jacket turns by 90 degree and then the cross section is one cone diversion water jacket and the crystallizer copper pipe in the cone diversion water jacket is isodiametric arced pipe and the water gap between the cone arced shaped diversion water jacket and the crystallizer copper pipe is a cone gap. The flowing way of the crystallizer cooling water is changed and the encrustation speed of an ingot in the crystallizer copper pipe is increased by changing the design structure and cooperation way between the crystallizer copper pipe and the diversion water jacket, so as to solve the problem that the lower port of the crystallizer copper pipe is quickly worn.
Description
Technical field
The utility model belongs to taper design and the manufacturing and the application of taper crystallizer water conservancy diversion water jacket, has solved in the casting process slab surface quality and has improved the strand internal structure.
Background technology
The crystallizer assembly is the core component on the continuous casting installation for casting, and it is made up of parts such as crystallizer copper pipe, water conservancy diversion water jackets.Solve the quality of wearing and tearing of copper pipe end opening and ingot casting in the core component with the big or small and variation in the slit between crystallizer copper pipe, the water conservancy diversion water jacket.
The steel flow of refining because of high temperature casts out steel ingot continuously after the crystallizer copper pipe cooling, go out in the process of casting at continuous casting, what manufacturer used at present all is to leave the even water seam of 3.2-5mm between crystallizer copper pipe and water conservancy diversion water jacket, make its strand like this in crystallizer copper pipe crust process, often be that copper pipe middle and upper part branch cooling velocity is fast, inside forms a large amount of column crystals, influences the quality of strand.Because the strand crust early, often causes copper pipe end opening rapid wear, reduces the service life of copper pipe, increased a large amount of costs, and the tiny crackle of casting billet surface often occurred, though do not influence slab quality, has a strong impact on the outward appearance of strand.Therefore, eliminate copper pipe end opening rapid wear and slab surface crack phenomenon and become the problem that presses for solution.
Summary of the invention
In view of above-mentioned present situation, the purpose of this utility model provides a kind of taper crystallizer water conservancy diversion water jacket, thereby solves the crust speed issue of ingot casting in crystallizer copper pipe by changing crystallizer cooling-water flow mode.
For achieving the above object, technical solution of the present utility model is: a kind of taper crystallizer water conservancy diversion water jacket comprises crystallizer copper pipe and is contained within the water conservancy diversion water jacket of crystallizer copper pipe outside; The section of wherein said one of them length of water conservancy diversion water jacket is awl arc water conservancy diversion water jacket, and the crystallizer copper pipe that is positioned at awl arc water conservancy diversion water jacket inside is isometrical curved pipe, making it to bore the water seam that forms between arc water conservancy diversion water jacket and the crystallizer copper pipe is an awl arc-shaped gaps, section after 90 ° of the described awl arc water conservancy diversion water jacket upsets is a taper water conservancy diversion water jacket, and the crystallizer copper pipe that is positioned at taper water conservancy diversion water jacket inside is isometrical pipe, and then boring the water seam that forms between arc water conservancy diversion water jacket and the crystallizer copper pipe is a tapered gaps.
Therefore, this novel reservation under the prerequisite that leaves the even water seam of 3.2-5mm between crystallizer copper pipe and the water conservancy diversion water jacket, by changing crystallizer copper pipe and the new structural design of water conservancy diversion water jacket, thereby changed crystallizer cooling-water flow mode, help improving under the situation of the crust speed of ingot casting in crystallizer copper pipe, solved the problem of crystallizer copper pipe end opening quick abrasion again.
According to being These characteristics, the wall thickness of related awl arc water conservancy diversion water jacket is to wait wall thickness, or wall thickness such as non-.Can select according to installing space and instructions for use.
In a word, the taper crystallizer water conservancy diversion water jacket that the utility model provides, be by the water conservancy diversion water jacket being processed into the tapered cambered surface of inner surface (up big and down small), because the crystallizer copper tube outer surface is of the same size, so produce the uneven water seam of size between taper water conservancy diversion water jacket and the crystallizer copper pipe, like this when crystallizer water flows from bottom to top, near end opening because water seam is narrow, the flow velocity height, cooling velocity fast (both heat exchange values are big), so crust speeds up, therefore when being about to be drawn out copper pipe, accelerated strand the speed of crust, short time reaches strand and pulls out the required shell thickness of crystallizer copper pipe, has significantly reduced the time of staying of thick stock shell in copper pipe, thereby has reduced the rate of wear of crystallizer copper pipe end opening.Corresponding water-cooled because the increasing of water seam causes the top cooling slowly, and heat flow density is low, helps the formation of equiax crystal and the formation of inhibition columnar grain at the middle and upper part of copper pipe branch.So both solve the problem of crystallizer copper pipe end opening wear block, also improved the internal structure of strand simultaneously, improved the quality of strand.

Fig. 2 is a cutaway view of Fig. 1 vertical view.
The specific embodiment
Below in conjunction with accompanying drawing embodiment to this novel being described further.
See taper crystallizer water conservancy diversion water jacket shown in Figure 1, provided a cutaway view of taper crystallizer water conservancy diversion water jacket front view.In the present embodiment, the section of the entire length of described water conservancy diversion water jacket is to be awl arc water conservancy diversion water jacket 1, and the crystallizer copper pipe 2 that is positioned at awl arc water conservancy diversion water jacket is isometrical curved pipes, making it to bore the water seam that forms between arc water conservancy diversion water jacket and the crystallizer copper pipe is an awl arc-shaped gaps, and this water gap is 3.2-5mm.Awl arc water conservancy diversion water jacket during this is novel is suitable for reading 3 with the big cone opening end that cooperates of crystallizer copper pipe 2; And the tiny cone opening end that cooperates that is positioned at awl arc water conservancy diversion water jacket and crystallizer copper pipe 2 is an end opening 4.
Fig. 2 has provided a cutaway view of taper crystallizer water conservancy diversion water jacket vertical view.In the present embodiment, be to the section after 90 ° of the awl arc water conservancy diversion water jacket of Fig. 1 front view upsets, this awl arc water conservancy diversion water jacket 1 is a taper water conservancy diversion water jacket, and the crystallizer copper pipe 2 that is positioned at taper water conservancy diversion water jacket is isometrical pipes, and making it to bore the water seam that forms between arc water conservancy diversion water jacket 1 and the crystallizer copper pipe 2 is a tapered gaps.Its water gap is similarly 3.2-5mm.
The taper crystallizer water conservancy diversion water jacket that the utility model is designed, from the cross section view of two different angles, the shape of crystallizer copper pipe that is reflected and water conservancy diversion water jacket is inequality.This is to implement key of the present utility model.
