Abstract
The utility model relates to a three-way casting tube for casting a super-large sized copper ingot, comprising a straight liquid inlet tube and a horizontal casting tube, wherein both sides of the horizontal casting tube are provided with a plurality of casting holes along an axial direction. In the utility model, both sides of the horizontal casting tube are additionally provided with the casting holes, therefore not only the convection of liquid copper in a crystallizer strengthened along the radial direction of the horizontal casting tube and axial convection caused by the momentum of fluid column is weakened, but also the temperature of all parts of the liquid copper in the crystallizer is made tend to be uniform, therefore, the defect of cold shut generated by the lower temperature of the middle of a large surface can be basically eliminated and the internal quality of the cast ingot can be ensured.
Description
Technical field
The utility model relates to the employed pouring device of a kind of copper slab ingot, relates to a kind of casting super large-scale copper slab ingot threeway cast tubes specifically.
Background technology
(1250mm * 220mm * 8000mm), generally use core-type induction furnace melting copper liquid adopts water mold to casting super large-scale H65 brass slab ingot, and semicontinuous casting machine is cast.Copper and zinc raw material melt in smelting furnace, refining, finish Hou Tongshui and change holding furnace over to, and copper water flows into crystallizer through cast tubes, by the water-cooled of crystallizer and the traction of casting machine, finishes the casting of brass ingot casting.Because the specification of ingot casting is bigger, when using traditional threeway gate spool to cast, can bring the problem of following two aspects: the one, copper liquid in crystallizer by the advection long flow path of two ends to the centre, cause the temperature difference of each several part copper liquid in the crystallizer bigger, the facet place copper liquid temperature height of horizontal cast tubes two ends correspondence, the middle part copper liquid temperature of two big faces is low, often forms a large amount of cold shut defectives at the middle part of big face, has a strong impact on the quality of ingot casting; The 2nd, copper liquid is bigger along the axial convection current of horizontal cast tubes in crystallizer, and the penetration depth of fluidization tower is big, has increased secondary oxidation and air-breathing, easily at inner slag inclusion and the gas hole defect of forming of ingot casting.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, a kind of casting super large-scale copper slab ingot threeway cast tubes is provided, in the time of can effectively solving ingot casting because of the advection of copper liquid not enough and axial casting defects such as the inside slag inclusion that caused of big caused big the middle part cold shut defective of convection current and secondary oxidation, pore, improve casting quality.
For achieving the above object, the utility model has adopted following technical scheme: it comprises feed liquor straight tube and horizontal cast tubes, and the both sides of horizontal cast tubes have some tapping holes vertically.During casting, when copper liquid flows out from horizontal cast tubes two ends, also flow out to crystallizer from the tapping hole of horizontal cast tubes both sides in the middle of.Both strengthened copper liquid in crystallizer along the convection current radially of horizontal cast tubes, weaken the axial convection current that the fluidization tower momentum causes, the copper liquid temperature trend that makes each several part in the crystallizer has again evenly been eliminated substantially because of the lower cold shut defective that produces of temperature in the middle part of the big face; Increase the zone of bubble and slag inclusion come-up, reduced the degree of depth that slips into of bubble and slag inclusion, helped slag inclusion and gas come-up, made the pore of ingot casting inside and dreg defect obtain tangible improvement, guaranteed the inside quality of ingot casting.
In order to prevent that copper liquid from upwards splashing at horizontal cast tubes two ends casting port position in casting cycle, a preferred version of the present utility model is: the horizontal range in the middle of the extremely horizontal cast tubes of the two ends casting gate upper port of horizontal cast tubes is greater than the horizontal range in the middle of the extremely horizontal cast tubes of lower port.
As shown from the above technical solution, the utility model adopts and sets up tapping hole in the both sides of horizontal cast tubes, both strengthened copper liquid in crystallizer along the convection current radially of horizontal cast tubes, weaken the axial convection current that the fluidization tower momentum causes, make the copper liquid temperature trend of each several part in the crystallizer even again, eliminated substantially because of the lower cold shut defective that produces of big face middle part temperature; Increase the zone of bubble and slag inclusion come-up, reduced the degree of depth that slips into of bubble and slag inclusion, helped slag inclusion and gas come-up, made the pore of ingot casting inside and dreg defect obtain tangible improvement, guaranteed the inside quality of ingot casting.

The specific embodiment
As shown in Figure 1, the threeway cast tubes is made up of feed liquor straight tube 1 and horizontal cast tubes 2, horizontal cast tubes 2 both sides are equidistant vertically to have some tapping holes 3, and tapping hole 3 also can not equidistant setting, and tapping hole 3 can enlarge setting to the two ends standoff distance gradually in the middle of horizontal cast tubes.Copper liquid both flowed out from two ends casting gate 4 during casting, also flowed out from both sides tapping hole 3 simultaneously.The two ends casting gate 4 of horizontal cast tubes 2 is set as inside scarf, make the horizontal range of upper port 5 to the horizontal cast tubes greater than the horizontal range of lower port 6 to the horizontal cast tubes, can prevent that copper liquid from upwards splashing at horizontal cast tubes two ends casting port position in casting cycle.
