Abstract
The utility model discloses a copper and copper alloy same-level multi-die hot-top casting device, which is characterized by comprising a plurality of sprue gates positioned at the same horizontal plane; the sprue gates have insulating structures made of high-temperature ceramic materials; and a crystallizer is arranged below each sprue gate. A secondary water cooling box is also arranged below each crystallizer and is connected with a water inlet pipe; and one side of the side lower part of the secondary water cooling box, which is close to a casting ingot, is provided with a cold water nozzle. In the casting device disclosed by the utility model, the same-level multi-die hot-top casting is realized, not only are the gas suction and slag inclusion of the copper liquor reduced, but also the production efficiency of casting is greatly improved, the number of operators can be reduced, the casting ingot yield and the processing yield of subsequent procedures are increased, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of casting device, relates in particular to a kind of copper and copper alloy same level multimode hot-top casting device.
Background technology
It is the non-ferrous metals casting technology of the U.S. in the invention seventies in last century that hot direct casting is made, and is widely used in the casting of aluminium and aluminium alloy.At the copper manufacture field, the report that prior art only has the copper alloy single mode hot direct casting of diameter below 115mm to make.At present, in copper and the copper alloy fusion-casting process, generally adopt the DC direct water-cooling casting of depositing or tundish crucible-supporting single mode crystallizer.The subject matter that common single mode direct water-cooling DC casting exists is: the crystallizer height is big, the liquid cave is dark, and gas that alloy melt is separated out in process of setting and slag inclusion can't in time be discharged, and cause ingot casting slag inclusion, pore and density low; The hotter top of the solid-liquid two-phase transition region casting of common DC casting is long, transition region is the zone that intensity is minimum on the ingot casting, percentage elongation is minimum, disturbance in the casting distraction procedure and vibrations all can cause this district to produce a large amount of crackles, crackle can not get timely feeding will form fire check, influences ingot quality; The used used crystallizer of the hotter top of crystallizer casting of common DC casting is high more than 40%, the contact area of copper liquid, ingot casting and crystallizer is much larger than hot top casting in process of setting, this contact area is big, ingot casting surface scull is easy to drawing crack, form ingot casting face crack and metal and leak extension, influence ingot surface quality.
The utility model content
In view of this, the purpose of this utility model provides a kind of copper and copper alloy same level multimode hot-top casting device.
Above-mentioned purpose realizes by following proposal:
A kind of copper and copper alloy same level multimode hot-top casting device is characterized in that described device comprises a plurality of sprue gates that are positioned at same horizontal plane, and described a plurality of sprue gates are high-temperature ceramic materials, and described each below, sprue gate all is equipped with crystallizer.
According to above-mentioned, it is characterized in that the below of described crystallizer also is provided with secondary water-cooled case, be connected with water inlet pipe on this secondary water-cooled case, and have the cold water spout near ingot casting one side at the side-lower of described secondary water-cooled case.
According to said apparatus, it is characterized in that described casting device comprises at least 3 sprue gates.
Casting device of the present utility model has been realized the casting of same level multimode, has both reduced air-breathing, the slag inclusion of copper liquid, improves casting production efficiency again greatly, can also reduce operative employee's number, has improved ingot casting lumber recovery and subsequent handling processing lumber recovery, reduces production costs.
Description of drawings
Fig. 1 is the structural representation of copper of the present utility model and copper alloy same level multimode hot-top casting device.
The specific embodiment
Referring to Fig. 1, copper of the present utility model and copper alloy same level multimode hot-top casting device comprise a plurality of sprue gates 1 that are positioned at same horizontal plane, a plurality of sprue gates 1 are high-temperature ceramic materials and make, and the below, sprue gate all is equipped with crystallizer 5, and crystallizer 5 is provided with water inlet 7 and delivery port 8.The insulation construction integral body that high-temperature ceramic materials on the casting platform is made constitutes heat top 3.Below crystallizer 5, also be provided with secondary water-cooled case 10, be connected with water inlet pipe 11 on the secondary water-cooled case 10, and have cold water spout 12 near ingot casting one side at the side-lower of secondary water-cooled case 10.Preferably, the same level multimode is cast can cast simultaneously 3 and above ingot casting.
Referring to Fig. 1, the copper liquid of pouring into a mould from copper liquid metaideophone depositing 2 forms same level liquid levels 6 on heat top 3, and under the cooling effect of crystallizer 5 and secondary water-cooled case 10, molten state copper liquid 4 is frozen into solid-state copper 9.
Claims (3)
1. copper and copper alloy same level multimode hot-top casting device is characterized in that described device comprises a plurality of sprue gates that are positioned at same horizontal plane, and described a plurality of sprue gates are high-temperature ceramic materials, and described each below, sprue gate all is equipped with crystallizer.
2. device according to claim 1 is characterized in that, the below of described crystallizer also is provided with secondary water-cooled case, is connected with water inlet pipe on this secondary water-cooled case, and has the cold water spout at the side-lower of described secondary water-cooled case near ingot casting one side.
3. device according to claim 1 and 2 is characterized in that described casting device comprises at least 3 sprue gates.
