Description
Technical field
The utility model relates to a kind of ingot mould of casting large steel ingot, belongs to ingot mould technical field.
Background technology
At present, increasing to heavy thickness, large substance, steel plate demand that flaw detection rank is high on market, object reduces welding, improves the quality of product.The steel plate weight demands of these large substances will arrive 40 tons even 50 tons, and the cast slab of existing maximum rolled plate just 50 tons, roll into maximum 37 tons of steel plate, be difficult to satisfy the demand.Produce 40 tons ~ 50 tons steel plates need develop 70 tons ~ 80 tons steel ingots and just can meet the demands, therefore must develop the large steel ingot mould that 70 tons ~ 80 tons forging rollings become sheet material.
Meanwhile, client is very high to the requirement of internal quality of steel plate, and steel ingot is larger, and internal flaw is more serious.Current ingot for forging is nearly all up big and down small, and cap mouth is large, and cap volume ratio is also large, and bottom is truncated cone-shaped, accounts for about 4% of steel ingot weight.The steel ingot of these features is forged into the billet yield of slab can be very low, only has 70 ~ 75%.Even if therefore have enough large steel ingot at present, the internal quality of steel plate that these steel ingots shut out also is difficult to meet the expectation of client to internal quality of steel plate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ingot mould being applicable to casting large steel ingot, this ingot mould can be used in the different large-scale steel ingot of poured weights difference, ingot shape, the steel ingot of cast is applicable to being forged into slab, can improve the lumber recovery of steel ingot and the service life of ingot mould.
The technical scheme solved the problems of the technologies described above is:
A kind of ingot mould being applicable to casting large steel ingot, it is made up of two parts at the bottom of ingot mould die body and ingot mold, ingot mould die body is upright cylinder, the inner chamber of cylinder is the ingot mould die cavity of ingot mould die body, it is round platform at the bottom of ingot mold, the upper bottom surface of round platform has circular groove, the inner chamber of circular groove is the ingot mould inner chamber at the bottom of ingot mold, the cylinder lower surface of ingot mould die body is connected with the round platform upper surface at the bottom of ingot mold, at the bottom of ingot mould die body and ingot mold, the outer circumference diameter of junction matches, at the bottom of the intracavity diameter of ingot mould die body junction and ingot mold, the intracavity diameter of junction matches, ingot mould die body and the periphery at the bottom of ingot mold are separately installed with hanger, there is the mouth of a river bottom surface at the bottom of ingot mold.
The above-mentioned ingot mould being applicable to casting large steel ingot, the upper end diameter of the ingot mould die cavity of described ingot mould die body is less than lower end diameter, and the upper end diameter of the ingot mould inner chamber at the bottom of described ingot mold is greater than lower end diameter.
The above-mentioned ingot mould being applicable to casting large steel ingot, the ingot mould inner chamber foot at the bottom of described ingot mold is segment-shaped, is multiple at the bottom of ingot mold, and the frustum cone height at the bottom of multiple ingot mold is different, and the degree of depth of the circular groove on differing heights round platform is different.
The beneficial effects of the utility model are:
Ingot mould of the present utility model adopts ingot mould die body and two body structures be connected at the bottom of ingot mold, and it is little that die body inner chamber is designed to two broad in the middle, can reduce cap volume ratio, reduces cutting head cutting tail, improves the lumber recovery of steel ingot; Have differing heights and volume at the bottom of ingot mold, ingot mould die body can water the steel ingot outpouring Different Weight and meets different demand from combining at the bottom of different ingot molds; Circular groove foot at the bottom of ingot mold is segment-shaped, can reduce back-end crop, can further improve the lumber recovery of steel ingot.The utility model structure is simple, can be combined into not isometric ingot mould easily, and the large-scale steel ingot different for poured weights, ingot shape is different, after ingot mould is divided into two parts, substantially increases Service Life of Ingot Mold, reduce steel ingot production cost.The utility model waters the steel ingot outpoured, and is first forged into slab, rerolls and makes sheet material, and this sheet material internal soundness is much better than the sheet material that steel ingot Direct Rolling becomes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: at the bottom of ingot mould die body 1, hanger 2, ingot mould die cavity 3, ingot mold 4, segment 5, the mouth of a river 6, ingot mould inner chamber 7.
Detailed description of the invention
The utility model is made up of 4 two parts at the bottom of ingot mould die body 1 and ingot mold.
Show in figure, ingot mould die body 1 is upright cylinder, and the inner chamber of cylinder is the ingot mould die cavity 3 of ingot mould die body 1, and the upper end diameter of the ingot mould die cavity 3 of ingot mould die body 1 is less than lower end diameter.
