Abstract
The utility model discloses a steel ladle aluminum deoxidation compound block for steelmaking. The steel ladle aluminum deoxidation compound block comprises a rectangular steel block, and is characterized in that the rectangular steel block is internally provided with a frustum-shaped through hole; an opening edge of the frustum-shaped through hole is leveled with the surface of the rectangular steel block; the frustum-shaped through hole is internally provided with a frustum-shaped aluminum block matched with the frustum-shaped through hole; a small-head plane of the frustum-shaped aluminum block is leveled with the surface of the rectangular steel block. According to the steel ladle aluminum deoxidation compound block for steelmaking, a deoxidizing agent block is settled and smelted due to a steel ladle aluminum core; aluminum is firstly smelted in the process of breaking through a dreg layer by the aluminum so that the yield of the aluminum is improved; the frustum-shaped aluminum block is frustum-shaped and is located in the frustum-shaped through hole so that the aluminum block is easy to rush out; the frustum-shaped aluminum block and the rectangular steel block can be separated conveniently and detected and weighed respectively.
Description
Technical field
The utility model relates to a kind of improvement of making steel by deoxidation composite block, ladle aluminium deoxidation composite block for a kind of steel-making specifically.
Background technology
Along with expanding economy, the market demand of deep drawing steel and extra-deep drawing steel is increasing.In the smelting process of deep drawing steel and extra-deep drawing steel, conventionally adopt reductor to carry out deep deoxidation.The reductor adopting at present, the alloy that normally metallic aluminium or ferro-aluminum remelting form, because aluminium is lighter, in order to make aluminium sink to fast molten steel bottom, is often surrounded by a certain proportion of iron block in aluminium inside.But above these reductors, in actual application, often have the following disadvantages: the one, because first aluminium touch molten steel, aluminium is in breaking through the process of slag blanket, and the aluminium outside steel core first melts, and meeting and slag react, the recovery rate that reduces aluminium in steel-core-aluminium, this has just caused the waste of aluminium; The 2nd, if employing is the alloy that ferro-aluminum remelting forms, although can sink to molten steel bottom owing to having strengthened proportion, because the alloy melting point after molten raises, makes to melt speed and slow down, affected deoxidation effect, also reduced the recovery rate of aluminium; The 3rd, the concrete ratio of alloying constituent adds and detects needs special-purpose melting unit, thus very complicated, and also the cycle is long, for the steel-core-aluminium of different specific weight in production process, is difficult to from directly distinguishing in appearance.Through retrieval, there is at present the report of aluminium iron clad core deoxidation piece, its profile is cylindrical or top in shape, center is surrounded by cylindricality iron block, but has no the report of the ladle aluminium core deoxidation piece that can overcome above prior art deficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of recovery rate, steel and aluminium that melts afterwards, can improve deoxidation effect and aluminium that first sinks to be clearly convenient to the ladle aluminium deoxidation composite block for steel-making that ratio separated, aluminium is convenient to adjust, be convenient to rapid detection steel al proportion.
In order to reach above object, the technical scheme that the utility model adopts is: ladle aluminium deoxidation composite block for this steel-making, comprise rectangular parallelepiped bloom, it is characterized in that: in rectangular parallelepiped bloom, be provided with frustum through hole, the opening's edge of frustum through hole is concordant with the surface of rectangular parallelepiped bloom, in frustum through hole, be provided with the frustum aluminium block matching with frustum through hole, the little head plane of frustum aluminium block is concordant with the surface of rectangular parallelepiped bloom, and the volume of frustum aluminium block is set by the part by weight requirement of frustum aluminium block with the ratio of the volume of rectangular parallelepiped bloom.
The utility model is also implemented by following measure: the frustum through hole in described rectangular parallelepiped bloom side by side be provided with two, the opposite direction of two frustum through holes.
Described frustum through hole top diameter is 25-40mm, and diameter at butt end is 60-90mm, is highly 30-60mm;
Described aluminium liquid can be also aluminum alloy melt.
The beneficial effects of the utility model are: compare with the block reductor using in the smelting process of deep drawing steel and extra-deep drawing steel at present, because deoxidizer block first sinks and melts afterwards, avoided aluminium aluminium in breaking through the process of slag blanket first to melt, improve the recovery rate of aluminium; Because frustum aluminium block is taper type, and be in frustum through hole, so can go out easily, be convenient to frustum aluminium block with the separated of rectangular parallelepiped bloom and detect and weigh respectively.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present utility model.
Fig. 2 is the schematic top plan view of the utility model Fig. 1.
In figure: 1, rectangular parallelepiped bloom; 2, frustum through hole; 3, frustum aluminium block.
Embodiment
With reference to Fig. 1, Fig. 2, make the utility model.Ladle aluminium deoxidation composite block for this steel-making, comprise rectangular parallelepiped bloom 1, it is characterized in that: in rectangular parallelepiped bloom 1, be provided with frustum through hole 2, the opening's edge of frustum through hole 2 is concordant with the surface of rectangular parallelepiped bloom 1, in frustum through hole 2, be provided with the frustum aluminium block 3 matching with frustum through hole 2, the little head plane of frustum aluminium block 3 is concordant with the surface of rectangular parallelepiped bloom 1, and the volume of frustum aluminium block 3 is set by the part by weight requirement of frustum aluminium block 3 with the ratio of the volume of rectangular parallelepiped bloom 1.
As improvement of the present utility model: the frustum through hole 2 in described rectangular parallelepiped bloom 1 side by side be provided with two, the opposite direction of two frustum through holes 2, during cast aluminum liquid, the interior cast aluminum liquid of a frustum through hole 2 first making progress to major part, stops when being poured into while meeting the requirements of liquid level; After cooling, by rectangular parallelepiped bloom 1 upset, make the major part of another frustum through hole 2 upwards, then to the interior cast aluminum liquid of another frustum through hole 2, when being poured into while meeting the requirements of liquid level, stop, cooling after, be ladle aluminium deoxidation composite block finished product for steel-making.If in the time of need to adjusting aluminium content, can adopt and not water the method solution of filling with; If need to detect the weight ratio of aluminium and steel, aluminium block can be gone out, separated with rectangular parallelepiped bloom 1, weigh respectively the weight of aluminium and steel.
Described frustum through hole 2 top diameters are 25-40mm, and diameter at butt end is 60-90mm, are highly 30-60mm;
Described aluminium liquid can be also aluminum alloy melt.
