Abstract
The utility model relates to a cooling device for increasing the continuous casting drawing speed, and the inner cavity curvature of the cooling device is the same as the curvature of the continuous casting billet. The cross-section of the inner cavity is the same as the cross-section of the continuous casting billet. After the relative positions of the cooling device centre and the crystallizer centre are accurately adjusted, the cooling water with the pressure is gone through from a water faucet. The forced cooling for the continuous casting billet is implemented, and the bulging deformation of the continuous casting billet is controlled.
Description
Technical field the utility model relates to a kind of cooler, and particularly metallurgical industry improves the cooler of continuous casting pulling rate.
The existing casting speed of background technology can not improve, and is the longer molten steel solidification that fully makes that crystallizer internal cavity can not be done on the one hand, improves the steel billet bulge deformation that pulling rate makes the band liquid heart easily, even bleed-out; Be that the secondary cooling zone intensity of cooling is low on the other hand, the water vapour that the cooling water of spray is volatilized easily hinders; Chinese patent ZL97 the 2 10429.1, the one, do not have the water of branch piece, and band pressure water column directly impacts the base shell, easily bleed-out; The 2nd, no water leg makes cooling water descend along base, can't collect discharge, makes the continuous casting billet inhomogeneous cooling, easily cracks; The 3rd, cause water resource waste.
The summary of the invention the purpose of this utility model provides a kind of cooler, and it can be effectively when improving the continuous casting pulling rate, and control continuous casting billet bulge deformation also strengthens cooling effect; In cooler divides water cavity, increase and divide the water piece, avoid being with the pressure water column directly to impact the base shell; At the outside water leg that increases of cooler, cooling water is discharged to certain orientation, recycle so that collect, economize on resources.
The purpose of this utility model is achieved in that and connects a mounting plate, bottom plate below crystallizer, on mounting plate, the bottom plate cooler is housed, this cooler inner chamber is combined by inner arc plate, outer arc plate, side plate, accurately adjust cooler lumen centers line and crystallizer internal cavity center line relative position, then cooler is fixed, on inner arc plate, outer arc plate, side plate, pass to the cooling water of band pressure, realize the pressure cooling of continuous casting billet and control its bulge deformation.
The bolt hole that the bolt hole, the rectangular opening by steel billet, the bolt hole that connects bottom plate, adjustment cooler lumen centers line and the crystallizer internal cavity position of center line that are connected with crystallizer are arranged on the mounting plate.
Rectangular opening by steel billet is arranged on the bottom plate, adjust the tank of cooler lumen centers line and the bolt hole of crystallizer internal cavity position of center line, the bolt hole that is connected mounting plate, collection cooling water.
The cooler inner chamber cross section that inner arc plate, outer arc plate, side plate combine is identical with the crystallizer internal cavity cross section, and inner chamber curvature is identical with continuous casting billet curvature.Several vertical and horizontal boshes are arranged around the inner chamber.
Several vertical and horizontal boshes are arranged on inner arc plate, outer arc plate, the side plate, several bolts hole that is connected with upper cover plate, lower cover are arranged at top, there is the bolt hole of the combination of interconnecting the side, and there are the bolt hole chewed with the bolt hole that divides the water piece to be connected, connection water and the hole of logical press water in the middle part.The water cavity of distributing to every bosh water is arranged around the logical pressure water hole.Branch water piece is arranged in the water cavity,, avoid the pressure water column directly to impact the base shell, cause bleed-out in order to the dispersive pressure water column.
Divide on the water piece bolt hole that is connected with inner arc plate, outer arc plate, side plate is arranged.
The end that water is chewed has the bolt hole that is connected with inner arc plate, outer arc plate, side plate, and other end inner chamber has the groove of dress O-ring seals, and the bore dia that leads to press water on intracavity diameter and inner arc plate, outer arc plate, the side plate is identical.
Rectangular opening by continuous casting billet, the bolt hole that is connected with inner arc plate, outer arc plate, side plate are arranged on upper cover plate, the lower cover.Horizontal tank on upper cover plate, lower cover and inner arc plate, outer arc plate, the side plate is formed the cooling water pilot hole.
The utility model because have and continuous casting billet cross section, inner chamber that curvature is identical, has several vertical and horizontal boshes around the inner chamber, has strengthened cooling effect, thereby has controlled the bulge deformation of continuous casting billet, has improved pulling rate.And cooling water is collected, concentrated discharging, recycle.
Description of drawings Fig. 1 is a front view; Fig. 2 is the A-A cutaway view; Fig. 3 is a stereogram.
The concrete structure of specific embodiment utility model can better be understanded from the description of following most preferred embodiment accompanying drawing 1 (front view), 2 (cutaway views), 3 (stereograms), but this and do not mean that accompanying drawing and explanation defines scope of the present utility model.
