Abstract
The invention provides a crystallizer for casting of copper-clad aluminum composite materials. The crystallizer comprises a stainless steel outer shell and a mould, a cooling copper sleeve is arranged between the stainless steel outer shell and the mould, a water inlet and a water outlet are formed outside the cooling copper sleeve, a plurality of cooling areas are arranged between the cooling copper sleeve and the stainless steel outer shell, and a plurality of tooth-shaped clearance grooves are formed in each cooling area. The number of the cooling areas is six, and four tooth-shaped clearance grooves are formed in each cooling area. The cooling copper sleeve structurally comprises six independent areas with tooth-shaped exchange areas, tooth-shaped structures are beneficial for increasing a cooling superficial area, meanwhile, the length of a water channel is increased, the flushing effect on the wall of the copper sleeve is enhanced through the turbulence effect of water flow, and the uniform cooling effect is improved. The independent areas are cooled inside, a casting cooling strength subarea is guaranteed to be adjustable, the precise control of cooling strength is achieved, and the stable control of a casting state can be achieved. Stainless steel shell materials are integrally forged, the structural design line is smooth and circular, and water flow resistance is reduced.
Description
Technical field
The invention belongs to the composite material processing technique field, relate in particular to a kind of copper cover aluminum composite casting crystallizer.
Background technology
The copper cover aluminum composite has copper aluminium bond strength height, even tissue, mechanics, the characteristics that electric property is good, and the critical component crystallizer in its production line is a kind of cooling device that solidifies for molten metal, with the size continuous casting moulding as requested of copper, aluminium liquid.Operation principle is that recirculated water enters this device, and the heat of molten metal is taken away by cooling water, and molten metal has realized that by the ordered crystalline of this equipment liquid arrives solid-state transformation, has finished casting process.Conventional crystallizer is mainly done shell by the irony of as cast condition, inner copper sheathing adopts red copper or brass material, cooling copper sheathing cooling water channel is designed to simple spirality, namely mill out spiral-shaped grooved at copper sheathing, the crystallizer of routine is had following defective for copper aluminium horizontal casting: 1, inhomogeneous cooling is even up and down for strand, this can cause cast sturcture inhomogeneous, and the blank that casts out is defective; 2, the intensity of cooling control accuracy is poor, causes the seasonal volatility of continuous casting blank temperature bigger, and performance differs greatly, the as-cast condition instability; 3, crystallizer shell casting attitude inner wall coarse is subjected to the current erosion easily, and has strengthened resistance to water-flow, has reduced cooling effectiveness.
Obtain when casting copper cover aluminum continuously stablize as-cast condition, require the continuous casting hauling speed to control more than 150mm/min, and crystallizer copper pipe cast part length is not more than 150mm
,Otherwise influence the casting of aluminium, it is big that crystallizer copper pipe cast part intensity of cooling is wanted, and the top and bottom cooling requires evenly, and every section intensity of cooling will aspire for stability, and needs a kind of novel crystallizer to overcome the above problems for this reason.
Summary of the invention
The present invention provides a kind of copper cover aluminum composite casting crystallizer in order to address the above problem.
Technical scheme of the present invention is achieved in that copper cover aluminum composite casting crystallizer, comprise stainless steel casing, mould, be provided with the cooling copper sheathing between stainless steel casing and the mould, cooling copper sheathing outside is provided with water inlet and delivery port, be provided with a plurality of cooled regions between cooling copper sheathing and the stainless steel casing, be provided with a plurality of tooth gaps grooves in each cooled region;
Described cooled region is six, is provided with four tooth gaps grooves in each cooled region.
The invention has the beneficial effects as follows: the present invention cools off the individual region that the copper sheathing structure is six band profile of tooth exchange areas, the tooth-shape structure design is conducive to increase the frigorimeter area, increase water channel length simultaneously, the turbulence effect of current has strengthened the developing result to the copper sheathing wall, has increased the even effect of cooling; Inner cooling individual region guarantees that casting intensity of cooling subregion is adjustable, can respectively distinguish intensity of cooling by regulating, and has realized the accurate control of intensity of cooling, can realize the stable control of as-cast condition; The stainless steel case material is that integral body forges, and the structural design lines smoothly are circular, reduce resistance to water-flow.
Description of drawings
Fig. 1 is generalized section of the present invention;
Fig. 2 is the generalized section of coolant jacket of the present invention;
Fig. 3 is vertical view of the present invention;
Fig. 4 is side view of the present invention.
Part explanation: 1, stainless steel casing, 2, the cooling copper sheathing, 3, water inlet, 4, delivery port, 5, mould, 6, the tooth gaps groove.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described: copper cover aluminum composite casting crystallizer, comprise stainless steel casing 1, mould 5, be provided with cooling copper sheathing 2 between stainless steel casing 1 and the mould 5, cooling copper sheathing 2 outsides are provided with water inlet 3 and delivery port 4, be provided with 6 cooled regions between cooling copper sheathing 2 and the stainless steel casing 1, be provided with 4 tooth gaps grooves 6 in each cooled region.
Cooling water enters this mould assembly by the water inlet 3 of crystallizer in the water system, the cooling water water temperature is 25 ~ 30 ℃ of normal temperature, flow-control to 10 ~ 15L/min, hydraulic pressure controls to 0.3 ~ 0.35MPa, cooling water under this condition enters in stainless steel case 1 and the tooth gaps groove 6 of cooling between the copper sheathing 2, flow trace flows according to the tooth-shape structure of copper sheathing, recirculated water flow through the heat that heat exchange has absorbed the molten metal of the graphite jig 5 of flowing through, thereby realize the casting solidification of metal, meanwhile leaving water temperature is increased to 55 ~ 60 ℃.Heat exchange described above is achieved in that recirculated water enters the tooth gaps groove interior 6 between stainless steel case 1 and the cooling copper sheathing 2, liquid metal is in graphite jig 5 internal flows, circulation was discharged from delivery port 4 positions after one week, the high heat of molten metal passes to graphite jig 5, the cooling water cooling copper sheathing 2 that passes to low in calories, because the contacting and heat exchange take place of cooling copper sheathing 2 and graphite jig 5, thereby the cooling that has realized molten metal is solidified, and liquid metal has been realized solidifying in order in graphite jig.Cooling copper sheathing 2 structures are the individual region of six band profile of tooth exchange areas, the tooth-shape structure design is conducive to increase the frigorimeter area, increase water channel length simultaneously, the turbulence effect of current has strengthened the developing result to the copper sheathing wall, in the individual region of six band profile of tooth exchange areas, the corresponding position during to the casting copper pipe cools off, and takes away the liquid metals heat by the cooling copper sheathing, make it to solidify to form and cast the base shell, continuously the base shell is pulled out crystallizer.
