Abstract
The utility model discloses a mold bottom of an ingot mold for casting of a vacuum induction furnace, relates to a mold bottom structure of the ingot mold, and solves the problem that the conventional flat bottom plate mold bottom easily causes entrainment and has short service life. The mold bottom of the ingot mold comprises a mold bottom liner and a mold bottom outer sleeve, wherein the mold bottom liner is a double-layer flat-bottom bowl-shaped liner consisting of an inner wall and an outer wall, a bowl wall inclines for an angle outwards; a first thermal insulation material is arranged between the inner wall and the outer wall; the mold bottom outer sleeve is a cylindrical outer sleeve made of cast iron, the center is provided with a round hole for accommodating the mold bottom liner, a second thermal insulation material is arranged between the mold bottom outer sleeve and the mold bottom liner, and an upper opening gap is sealed by fire clay; middles of two sides of the outer wall of the mold bottom outer sleeve are provided with lifting lugs. The bowl-shaped mold bottom liner in the mold bottom of the ingot mold can quickly form a molten pool at the bottom of the ingot mold, the ingot mold can bear high-temperature impact, and the probability of impacting the mold during casting is reduced, so that the quality of electrodes is improved and the service life of the ingot mold is prolonged.
Description
Technical field
The utility model relates to ingot mold bottom structure, at the bottom of referring in particular to a kind of mould of ingot mould of vaccum sensitive stove cast use.
Background technology
Vaccum sensitive stove is a kind of special converter, smelts, pours into a mould overall process and carry out under vacuum state.
The pouring technology of vaccum sensitive stove is mould note: the molten steel of high-temperature liquid state, by intermediate chute (cast gate) transition, is injected to ingot mould, and cooling after coagulation is solid-state steel ingot.
The pouring technology of vaccum sensitive stove adopts top teeming process, by intermediate chute (cast gate) transition, pour molten steel into ingot mould, at the bottom of existing ingot mold, be generally baffle plate structure, baffle plate by mould at the bottom of inner panel and settle the mould bottom plating of inner panel at the bottom of mould to form, at the bottom of mould, inner panel 11 is circular flat base plates as Figure 1-Figure 2, it is to be made up of refractory material (clayey), at the bottom of mould, the top and bottom diameter of inner panel 11 differs 35-40mm, according to the size of ingot shape, use the flat underside of different size, at the bottom of mould, inner panel 11 is placed in the mould bottom plating (not shown) of a cast iron manufacture, between the two, fill with quartz sand, gap place is used fire clay sealing, after baking, form ingot mold base plate, when use, ingot mould is placed on the mould bottom plating of cast iron manufacture and pours into a mould.
The ingot mould chamber whole height of large-scale vacuum induction furnace is all more than 3-4 rice, inner panel 11 at the bottom of the flat mould of the refractory material system of use said structure, in the time of cast, molten steel directly impacts ingot mould bottom, easily produce punch die and sticking to mould, affect stable components and the Service Life of Ingot Mold of electrode, also increased the carbon in molten steel (C) content simultaneously, formation is mingled with, be unfavorable for the smelting of clean iron and steel, and because punch die and sticking to mould cause steel ingot drawing crack, easily there are quality problems and cost is raise in the time being solidified as solid-state steel ingot.
Utility model content
The purpose of this utility model is the problem existing in order to overcome prior art, and a kind of phenomenon that punch die and sticking to mould produce can stop to pour into a mould time is provided, thereby at the bottom of improving the ingot mold of vaccum sensitive stove cast use of electrode quality and Service Life of Ingot Mold.
The purpose of this utility model is achieved through the following technical solutions:
At the bottom of a kind of ingot mold of vaccum sensitive stove cast use, it is characterized in that comprising:
Inner bag at the bottom of mould, it is the flat bowl of the bilayer being made up of an inwall and outer wall type inner bag, the outward-dipping angle [alpha] of bowl wall, inwall and outer wall adopt density high, and resistant to elevated temperatures material is made, and uses the first filled thermal insulation materials between inwall and outer wall;
Overcoat at the bottom of mould, is the cylinder type overcoat of being manufactured by cast iron, and central authorities are provided with circular hole, inner bag at the bottom of the described mould of arrangement in circular hole, and the second filled thermal insulation materials of the gap between inner bag at the bottom of overcoat and mould at the bottom of mould, gap suitable for reading place is used fire clay sealing; At the bottom of mould, in the middle of the both sides of outer casing outer wall, be provided with hanger.
The outward-dipping angle [alpha] of described bowl wall is 8 °.
Described inwall and outer wall adopt high aluminum-containing mullite material.
Described the first insulation material is asbestos disks.
At the bottom of top the rim of a bowl of described inwall and bottom bowl, be to seamlessly transit with bowl wall intersection.
Described the second insulation material is quartz sand.
The beneficial effects of the utility model:
At the bottom of the ingot mold of vaccum sensitive stove cast use of the present utility model, formed by overcoat at the bottom of the mould of inner bag at the bottom of inner bag at the bottom of bowl pattern and storing mould, at the bottom of bowl pattern wherein, inner bag can form molten bath in ingot mould bottom rapidly, make it bear high temperature impact, reduce the probability of punch die while cast, thereby improved quality and the Service Life of Ingot Mold of electrode.This mould bottom structure is simple, practical, is conducive to promote the use of in the industry.
For further illustrating above-mentioned purpose of the present utility model, design feature and effect, below with reference to accompanying drawing, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is the structure chart of inner panel at the bottom of mould in existing baffle plate;
Fig. 2 is the cutaway view that Fig. 1 looks up;
Fig. 3 is the structure chart of the utility model baffle plate;
Fig. 4 is the structure chart of inner bag at the bottom of mould in Fig. 3 baffle plate;
Fig. 5 is the electrode schematic diagram adopting after the cast of Fig. 3 baffle plate.
The specific embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to the specific embodiment of the present utility model.
Referring to Fig. 3, at the bottom of the ingot mold of vaccum sensitive stove cast use of the present utility model, comprise:
