Abstract
The utility model provides a copper bar up-drawing casting mold used for a continuous casting machine. The copper bar up-drawing casting mold comprises a rectangular cooling sleeve; a partition board is arranged in the sleeve, and separates the inner cavity of the sleeve into an inner layer and an outer layer for flowing and cooling of cooling water; a protective sleeve is coated on the outer side of the lower part of the sleeve; a graphite mould is sleeved on the inner side of the lower part of the sleeve; a plurality of longitudinal grooves are formed on the contact surface of the inner wall of the sleeve and the cooling water; and solid heat conducting powder is filled between the inner wall of the sleeve and the up-drawn copper bar. The copper bar up-drawing casting mold provided by the utility model improves the cooling effect, and has the advantages of energy conservation, consumption reduction, improvement of production efficiency and prolonged service life. In addition, the quality of the copper bar casting is stabilized and improved.
Description
Technical field
The utility model relates to a kind of equipment that is used to produce the copper bar strand, draws crystallizer on particularly a kind of copper bar that is used for conticaster.
Background technology
Drawing crystallizer on the copper bar is the critical component of conticaster, its effect be make copper liquid according to required shape in crystallizer rapidly, the cooled and solidified copper bar strand that forms the smooth surface interior solid is upwards drawn equably.Traditional crystallizer main body is the rectangle cooling collar that is welded by flat copper coin, being provided with dividing plate in the sleeve pipe is separated into cannula cavity inside and outside two-layer, cooling water enters internal layer from the top of crystallizer and flows downward, bottom from crystallizer enters skin then, be folded to the top of flowing and flow out, to reach abundant cooling purpose from crystallizer.The outside in the sleeve pipe bottom is coated with protective sleeve, is with graphite mo(u)ld in the inboard of sleeve pipe bottom.During work, be to pass crystallizer from top to bottom with a special-purpose leader device earlier to contact with copper liquid, copper liquid then up is pulled, copper liquid is introduced in the graphite mo(u)ld (primary cooling zone), through preliminary cooling after coagulation crust, form have certain geometrical shape, major part has been solidified, certain mechanical strength is arranged but the still very high casting embryo of temperature; When up drawing was through secondary cooling zone again, the radiant heat that is absorbed the casting embryo by cooling water further cooled off, and the copper bar strand that forms typing is at last upwards drawn.The crystallizer of this structure is because the casting embryo is to dispel the heat by the radiation mode of casting embryo in the cooling of secondary cooling zone, and its heat radiation cooling effect is not fine.Because be subjected to the influence of the factor of cooling off, the lead speed of strand is generally very low.In addition, the crystallizer that flakiness ratio is big very easily is out of shape, and has a strong impact on the applying with graphite mo(u)ld, influences cooling effect and service life.
The utility model content
The purpose of this utility model exactly in order to solve the problems referred to above that prior art exists, provides on a kind of copper bar that is used for conticaster with new structure and draws crystallizer.
The technical solution of the utility model is: draw crystallizer on a kind of copper bar that is used for conticaster; comprise a rectangle cooling collar; be provided with dividing plate in the sleeve pipe cannula cavity is separated into the inside and outside two-layer of confession flow of cooling water refrigeration; the outside of sleeve pipe bottom is coated with protective sleeve; the inboard of sleeve pipe bottom is with graphite mo(u)ld; be characterized in that the contact-making surface of described internal surface of sleeve pipe and cooling water is provided with many longitudinal grooves.
Draw on the described copper bar crystallizer when work internal surface of sleeve pipe and on draw and be filled with the solid conductive heat powder between the copper bar.
Draw crystallizer owing to adopted above technical scheme on the copper bar that is used for conticaster of the present utility model, make it compared with prior art, have following advantage and and characteristics:
1, owing on the contact-making surface of internal surface of sleeve pipe and cooling water, is provided with many longitudinal grooves, and when work internal surface of sleeve pipe and on draw and be filled with the solid conductive heat powder between the copper bar, increased radiating effect greatly, can quicken solidifying and cooling off of copper liquid, thereby can improve lead speed and production efficiency.Compared with prior art, lead speed can improve 1.5-2 times.
2, owing on the contact-making surface of internal surface of sleeve pipe and cooling water, be provided with many longitudinal grooves, increased the rigidity of inwall, can reduce inwall deflection in use at primary cooling zone, thereby guarantee the applying degree of inwall and graphite mo(u)ld to greatest extent.It is good more that inwall and graphite mo(u)ld are fitted, and once Leng Que effect is good more, and the speed of moulding is fast more; The applying degree of inwall and graphite mo(u)ld is high more, and the cooling of casting embryo is even more, and quality is good more.
3, prolonged the service life of crystallizer;
4, stabilized and increased the quality of casting embryo.
Description of drawings
Fig. 1 is the original state structural representation that is used for drawing on the copper bar of conticaster crystallizer;
Fig. 2 is the working state structure schematic diagram that is used for drawing on the copper bar of conticaster crystallizer;
Fig. 3 is that K-K of Fig. 2 is to the sectional structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, draw crystallizer on the copper bar that is used for conticaster of the present utility model, comprise a rectangle cooling collar 1, be provided with dividing plate 2 in the sleeve pipe 1 cannula cavity is separated into the inside and outside two-layer of confession flow of cooling water refrigeration, sleeve pipe 1 top is provided with the inlet tube 11 and the outlet 12 of cooling water, inlet tube 11 is communicated with the internal layer of cannula cavity, and outlet 12 is communicated with the skin of cannula cavity.The outside of sleeve pipe bottom is coated with protective sleeve 4, and the inboard of sleeve pipe bottom is with graphite mo(u)ld 5, is provided with many longitudinal grooves 131 on the contact-making surface of the inwall 13 of sleeve pipe 1 and cooling water.When sleeve pipe is worked internal surface of sleeve pipe and on draw and be filled with solid conductive heat powder 6 between the copper bar.
The course of work of drawing crystallizer on the copper bar that is used for conticaster of the present utility model can be described as follows in conjunction with Fig. 1, Fig. 2: copper liquid up is pulled from the crystallizer bottom by special use leader device 3, during through primary cooling zone (graphite mo(u)ld 5), the heat of copper liquid is taken away by recirculated cooling water through inwall 13 conduction of graphite mo(u)ld 5 and rectangle cooling collar 1.When passing through primary cooling zone from lower to upper, copper liquid solidifies crust gradually, begin to take shape have certain geometrical shape, major part has been solidified, certain mechanical strength is arranged but the still very high casting embryo of temperature.Again up drawing when the secondary cooling zone, earlier by fill internal surface of sleeve pipe with on draw the conduction heat that solid conductive heat powder 6 between the copper bar absorbs the casting embryos, conduction further cools off for internal surface of sleeve pipe and cooling water again, forms the copper bar strand 7 of finalizing the design at last and upwards draws.
Draw crystallizer on the copper bar that is used for conticaster of the present utility model and make the secondary methods for cooling become heat loss through conduction by traditional heat loss through radiation, increased the effect of heat radiation, added solid conductive heat powder can not influence the physical property and the surface quality of casting embryo.
