Description
Technical field
The utility model relates to a kind of water jacket of split type band diversion flume, is specially the water jacket that is used for efficient billet caster crystallizer of metallurgy industry, belongs to the metallurgical continuous casting technical field.
Background technology
Crystallizer is the critical component of conticaster; By copper pipe, be coated on parts such as the outside water conservancy diversion water sleeve of copper pipe magnetic stirrer and form; The crystallizer of billet caster for guaranteeing molten steel even shape shell in crystallizer, and reaches certain shell thickness in the crystallizer exit position under the condition of high pulling rate; Require to reach the bight cooling evenly around the crystallizer, and have enough cooling effectiveness.In the known crystallizer; Its copper pipe is to be formed through specially designed plug and external mold extruding drawing by the heavy wall copper pipe; After the completion of extruding drawing procedure, withdrawing from plug, the residual stress reason of crystallizer copper pipe because of eliminating causes arc radius to change; Even the copper pipe that same set of die production goes out, its arc diameter changes difference even reaches more than 1 meter.
On the other hand, existing crystallizer copper pipe is directly to link to each other with the crystallizer cylindrical shell, and the upper surface of junction crystallizer and draw-in groove are to locate through the profile circular arc of copper pipe; The variation of copper pipe radian after moulding is often ignored by manufacturer, and being defaulted as is the circular arc of design, therefore; In case big variation takes place circular arc, will cause the center of circle of copper pipe circular arc and casting machine center that bigger deviation takes place, when casting machine is produced with high pulling rate; Be easy to cause base shell growth inhomogeneous, even problem such as bleed-out.
After known crystallizer water conservancy diversion water jacket is the corrosion resistant plate punch forming; Be welded; Because dimensional accuracy is difficult to guarantee in the process, the water seam non-uniform phenomenon in the work between water conservancy diversion water jacket and the crystallizer copper pipe very easily takes place, and directly causes the growth of base shell inhomogeneous.Chinese invention patent " cooling water forms the method and the crystallizer of turbulent flow in a kind of continuous cast mold " (application number: 200810079470.6 applyings date: 2008-09-25) disclosed turbulence type cooling water continuous cast mold; Forming rough water seam in the work between water jacket and the crystallizer outer surface makes cooling water flow with turbulence form; Strengthened the cooling water heat exchange effect; Its weak point is the uniformity consistency that this structure can not be guaranteed water seam between water jacket and the copper pipe, thereby the turbulent flow inequality occurs; (application number: 200920105634.8 applyings date: 2009-02-04) disclosed is to be provided with a plurality of gap adjustment parts between inner water sleeve and the copper pipe to utility model patent " arc tube type mold "; Its weak point is in the actual use; When water seam inequality occurring; Regulate difficulty, the adjusting of passing through that can not be strict realizes water seam uniformity.
Summary of the invention
The purpose of the utility model is the problem to background technology proposed; A kind of water jacket of split type band diversion flume is provided; Be assembled into by inside and outside arc half water sleeve seal, securing member, alignment pin, water jacket is to be two splits of cut-off rule with crystallizer cylindrical shell center line, and what separate simultaneously is water jacket inner lead, bight water channel, side and cambered surface water channel; Guaranteed the controllability of cooling water seam from frame for movement; Can avoid the center of circle and the casting machine center of copper pipe circular arc that deviation takes place, help improving water seam heat exchange effect, reduce the production run cost.
The technical scheme of the utility model is: the water jacket of split type band diversion flume is to be enclosed in the outside water conservancy diversion water jacket of crystallizer copper pipe, comprises inner arc half water jacket, outer arc half water jacket, seal, securing member and alignment pin; There is the seal sealing in gap between the water jacket of described split type band diversion flume and the crystallizer cylindrical shell; Also there is seal to separate between the inlet water tank of crystallizer cylindrical shell and the water tank; There is snap ring the crystallizer copper pipe upper end; Snap ring top is the crystallizer loam cake, it is characterized in that: described inner arc half water jacket and outer arc half water jacket are to be two splits of cut-off rule with crystallizer cylindrical shell center line, are connected through securing member and alignment pin between inner arc half water jacket and outer arc half water jacket; Between the water jacket of split type band diversion flume and the crystallizer copper pipe seal is arranged.Its beneficial effect is: through seal the inlet water tank and the water tank of crystallizer cylindrical shell are cut apart; The crystallizer copper pipe upper end is through snap ring and crystallizer loam cake restriction upper and lower displacement; Crystallizer copper pipe is circumferentially surrounded by split type band tank water conservancy diversion water jacket and through fastener bolt crystallizer copper pipe and split type band tank water conservancy diversion water jacket is fitted tightly, and guarantees the consistent of crystallizer copper pipe profile radian and water jacket inner chamber groove face radian from structure.
The water jacket of aforesaid split type band diversion flume is characterized in that: on the inner chamber of described inner arc half water jacket and outer arc half water jacket, being processed with five given depths and equally distributed vertical rib at least, promptly is diversion flume between adjacent two ribs.Its beneficial effect is: described rib will be separated along the cooling-water duct of the circumferential diverse location of water jacket inner chamber; Form a plurality of diversion flumes; And bight aquaporin and side and cambered surface aquaporin also separated, help cooling water and flow by set path, improve water seam heat exchange effect.
The water jacket of aforesaid split type band diversion flume is characterized in that: the upper end of described inner arc half water jacket and outer arc half water jacket has delivery port, two ends have water inlet down.Its beneficial effect is: through control intake-outlet flow size, reach the effect of scalable cooling water inflow.
The water jacket of aforesaid split type band diversion flume is characterized in that: described inner arc half water jacket and the outer arc half water jacket outside are evenly distributed with crisscross gusset.Its beneficial effect is: can guarantee that split type band tank water conservancy diversion water jacket itself has enough big rigidity with respect to the thin-walled mould copper pipe, can control the distortion of copper pipe on the structure.
The beneficial effect of the utility model is: (1) can guarantee the accuracy of manufacture of conticaster crystallizer from frame for movement; Avoid occurring the center of circle and the casting machine centre deviation problem of copper pipe circular arc; Simultaneously can reach the control cooling purpose, thereby guarantee casting machine steady production under high pulling rate; (2) can make the crystallizer copper pipe of thin-walled press close to solidified shell through regulating hydraulic pressure, reduce the air gap between base shell and the copper pipe, increase the heat exchange effect of crystallizer; (3) because frame for movement has guaranteed the controllability of cooling water seam, can design narrower water seam and improve the heat exchange effect, perhaps reduce the crystallizer water yield, reduce the production run cost; (4) reduced the wall thickness of crystallizer copper pipe significantly; Not only reduced the manufacturing cost of single copper pipe; Because the assurance of dimensional accuracy has reduced the wearing and tearing of copper pipe, can also improve the service life of single copper pipe simultaneously; Thereby reduce the maintenance cost of spare part significantly, and can improve the production efficiency of casting machine and the stability of product quality effectively.
