Abstract
The invention discloses a tundish for vacuum smelting furnace casting. The tundish comprises a blank body, a buffer bag and leaking holes, wherein the buffer bag is a hemispherical buffer bag and is arranged on the bottom surface of the blank body, the leaking holes are formed in the bottom surface of the blank body and are uniformly distributed around the buffer bag. When the tundish is used, the problems of water cooling ingot mold burnthrough, product coarse crystallization and the like can be effectively solved, the operation safety is improved, and the production cost is reduced.
Description
Technical field
The present invention relates to one to build with tundish, particularly a kind of vacuum induction melting furnace is built and is used tundish.
Background technology
The casting method that hydrogen bearing alloy vacuum induction melting furnace used adopts usually is that aluminium alloy is directly poured into water cooling ingot mould by crucible.Vacuum induction melting furnace has the characteristic of negative pressure, alloy temperature controls to be judged by instrument and workman's experience, and the method temperature control difficulty that use crucible is directly poured into water cooling ingot mould is large, casting process flow velocity is uneven, during cast, aluminium alloy directly forms a fixing camber line and repeats to wash away, and very easily causes that water cooling ingot mould damages, the unequal problem of alloy crystallization thickness.Therefore crucible cast exists that operational risk is large, the not high defect of product quality.
Summary of the invention
For solving the problem, the invention provides a kind of vacuum induction melting furnace builds with tundish, is naturally built by the secondary being arranged on the tundish on water cooling ingot mould, effectively can solve water cooling ingot mould and burn the problem such as partially thick with product crystallization, improve the security of operation, reduce production cost.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of vacuum melting furnace is built with tundish, and it is characterized in that, comprise idiosome, buffers packet and small opening, described buffers packet is hemispherical buffers packet, is arranged on idiosome bottom surface, and described small opening is arranged on idiosome bottom surface and is evenly distributed on buffers packet surrounding.
Further, described idiosome bottom surface is concave bottom surface.
Further, described small opening is 4-5.
Further, described idiosome adopts aluminium oxide and quartz gravel sintering to form.
Further, the height of described buffers packet is the half of idiosome height.
Beneficial effect:
When the present invention passes through to install tundish, cast additional on water cooling ingot mould, aluminium alloy flows into " tundish " hemispherical buffers packet top, and aluminium alloy forms secondary and naturally pours into a mould, and aluminium alloy flows into water cooling ingot mould by small opening.Use this tundish, water cooling ingot mould obtains effective protection, and aluminium alloy forms second pouring and is divided into many groups and flows into water cooling ingot mould.In addition, tundish bottom is designed with and reduces residual in tundish of aluminium alloy to lower recess, builds the alloy crystal refinement, evenly obtained.Tundish of the present invention effectively can solve water cooling ingot mould and burn the problem such as partially thick with product crystallization, improves the security of operation, reduces production cost.

Fig. 1 is the perspective view of vacuum melting furnace tundish of the present invention;
Fig. 2 is the top view of vacuum melting furnace tundish of the present invention;
Fig. 3 is the sectional view of vacuum melting furnace tundish of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Vacuum melting furnace is built with tundish, and comprise idiosome 2, buffers packet 1 and small opening 3, described buffers packet 1 is hemispherical buffers packet, is arranged on idiosome bottom surface 4, and described small opening 3 is arranged on 4-5 hole of idiosome bottom surface, is evenly distributed in buffers packet surrounding.Flow out for convenience of aluminium alloy, idiosome bottom surface is concave bottom surface.Described idiosome adopts aluminium oxide and quartz gravel sintering to form, and the height of described buffers packet is the half of idiosome height.
Embodiment 1: tundish selects aluminium oxide and quartz gravel forming and sintering, idiosome external diameter 140mm, internal diameter 130mm, high 50mm, centre bit is equipped with that hemispherical is slow fills bag radius 25mm, centered by buffers packet central point, mark signature line, cross hairs is the center of circle according to central point 45mm place, makes the small opening of diameter 30mm, totally four.In use, hemispherical during cast in aluminium alloy inflow tundish is slow fills bag, aluminium alloy forms secondary and naturally pours into a mould distribution and enter four small openings and naturally enter water cooling ingot mould, because tundish bottom is designed to recessed radian, the aluminium alloy stayed between small opening flows in small opening along recessed bottom again, finally flows into water cooling ingot mould, water cooling ingot mould can be solved and burn the problem such as partially thick with product crystallization, tundish residual material is less, improves the security of operation, reduces production cost.
Claims (5)
