Abstract
The invention discloses an ingot casting mould with a cooling device and an ingot casting method thereof. The alloy ingot casting mould comprises a pouring groove which takes a reverse convex shape due to a small inner cavity bottom and a large inner cavity opening; the steps of both sides of the inner cavity are respectively provided with a truncated-cone-shaped hoisting iron core of which the diameter at the lower end is large and the diameter at the upper end is small; the hoisting iron core is provided with a cooling open hole with an opening at the top end; and the cooling open holes are inserted with a cooling hopper respectively. The ingot casting method comprises a pouring process, a cooling process and a mould-release process. In the cooling process, a water solution of sodium dodecylsulphate and an anionic surface active agent is applied to cool the hoisting iron cores and the upper surface of the alloy by the cooling hoppers. The invention can facilitate the even adding of acooling agent and even cooling of the whole alloy ingot, reduce the segregation of elemental composition and eliminate the wrinkles, cracks, bubbles and macro shrinkages on the surface of the alloy i ngot and on the lateral walls of a hoisting hole, thereby improving product quality and rate of finished goods.
Description
Technical field
The present invention relates to technical field of smelting, especially a kind of alloy cast ingot mould and casting ingot method with cooling device.
Background technology
At present, use a kind of large-scale alloy cast ingot mould in the pouring technology of relatively large alloy pig, the inner chamber of this alloy cast ingot mould is the big convex shape of end osculum, place a truncated cone-shaped lifting iron core that the big upper end diameter of lower end diameter is little on the step of the both sides of inner chamber respectively, lifting iron core upper end exceeds the through hole that there is vertical central ingot mould position suitable for reading.After the cast cooling of alloy liquation, hoisting machine is transported to suitable position with the alloy pig demoulding easily by traction lifting iron core, will lift after iron core pounds, and forms hole for hoist in the both sides of alloy pig, and this hole for hoist can also make things convenient for the alloy pig secondary to load and use.Prior art alloy pig surface cool method mainly contains natural cooling, direct water-cooling method, covering insulation cooling method, atomizing cooling method etc., the shortcoming of these methods is that the alloy pig homogenization of composition is undesirable, it is poor that surface quality guarantees, the alloy pig surface easily forms crackle, bubble etc.Alloy pig condenses into solid-state process from liquid state, and cool time is longer, causes the segregation and the volume contraction of certain ingredients easily, and a lot of macrocavity and crackle appear in the alloy pig upper surface, have influenced product quality and finished product rate.Especially it is little to lift core volume, quick heating, cooling is slow, the section that it contacts with alloy shrinks the back in the cooling of alloy liquation and forms the space, this position, space cooling is slow again, forms a large amount of macrocavity and crackle, especially macrocavitys in the process that the alloy cooling is shunk and intake easily on the sidewall of alloy pig hole for hoist, alloy pig is blasted in the secondary smelting process easily, gives and uses the producer of ZINC ALLOY to cause security incident.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of alloy cast ingot mould with cooling device is provided, its cooling device can make things convenient for cooling agent evenly to add, alloy pig hole for hoist and upper surface good cooling effect.
Another purpose of the present invention provides uses this to have the casting ingot method of the alloy cast ingot mould of cooling device.
The object of the present invention is achieved like this: a kind of alloy cast ingot mould with cooling device, it comprises that osculum at the bottom of the inner chamber is down the pouring basin of convex shape greatly, on the step of the both sides of inner chamber, place a truncated cone-shaped lifting iron core that the big upper end diameter of lower end diameter is little respectively, lifting iron core upper end exceeds the through hole that there is vertical central ingot mould position suitable for reading, it is characterized in that: it also comprises two cooling funnels, the cooling funnel comprises the leakage cup, below leaking cup is cylinder and fistulae, described lifting iron core has the cooling of upper end open hollow, the fistulae of two cooling funnels insert respectively two the lifting iron cores cooling hollow in, the cooling funnel cylindrical cap the lifting iron core the upper end.
For the lifting iron core can accurately be located, on the step of the both sides of pouring basin inner chamber, positioning convex is set, correspondingly the pit corresponding with positioning convex arranged in the lower end of lifting iron core.
A kind of use has the casting ingot method of the alloy cast ingot mould of cooling device, comprises the steps:
(1) cast: two truncated cone-shaped lifting iron cores are placed on respectively on the step of pouring basin inner chamber both sides, the alloy of fusion is injected in the inner chamber of pouring basin at leisure;
(2) cooling: with the fistulae of two cooling funnels insert respectively the cooling of two lifting iron cores hollow in, leakage cup at the cooling funnel injects cooling agent, cooling agent flows into the hollow cooling lifting of the cooling iron core of lifting iron core lentamente by fistulae, cooling agent from lifting iron core upper end open flow out and cylinder below leaking cup flow to the alloy pig hole for hoist above, cooling agent spreads the cooled alloy upper surface at alloy surface;
(3) demoulding: after the complete cooled and solidified of alloy, take away the cooling funnel, hoisting machine traction lifting iron core is placed on correct position with alloy pig, pounds the lifting iron core again.
Described cooling agent is the aqueous solution of dodecyl sodium sulfate and anion surfactant.
The weight portion proportioning of described each raw material of cooling agent is: 1～2 part of dodecyl sodium sulfate, 1～2 part of anion surfactant, 500～1000 parts in water.
Described dodecyl sodium sulfate molecular formula is C
18H
29SO
3Na.
Described anion surfactant is C preferably

Cool off for cooling agent can slowly be flowed out evenly, can place a gauze in the leakage cup bottom of cooling funnel.
The present invention compared with prior art has following advantage: two lifting iron cores of alloy cast ingot mould of the present invention have the cooling of upper end open hollow, the cooling funnel fistulae be inserted into the lifting iron core cooling hollow in, it can make things convenient for cooling agent evenly to add, and alloy pig integral body is evenly cooled.Use special-purpose cooling agent in addition, can reduce the elemental composition segregation, guarantee that alloying component is evenly distributed in the foundry goods as far as possible, eliminate fold, crackle and the bubble on alloy pig surface simultaneously, surface smoothness and flatness increase, thereby have improved product quality and finished product rate.Because the volume ratio of lifting iron core is less, the alloy heating that it is very easy to be melted, cooling rate is slow near the lifting iron core, in addition because alloy monolithic cooling contraction, between lifting iron core and alloy, form the gap again, this just forms macrocavity easily on alloy pig hole for hoist sidewall, adopt the cooling device and the method for this structure, can solve this type of problem well.
