Abstract
The utility model discloses an improved steel ingot mould which is characterized in that the top end of the mould body of the slab steel ingot mould is correspondingly and closely provided with a cambered surface mould cover provided with two or a plurality of conical air exhaust ports. When heated liquid steel is poured into the mould body, normal temperature air in the mould body is exhausted from the air exhaust ports by heated upgoing airflow. When the liquid steel goes into the space of the cambered surface mould cover, the heated airflow is quickly pre-heated, warmed up and stores heat at the mould cover. When the liquid steel goes into the conical air exhaust ports, free slag separated out by the liquid steel are gathered and covered flat on the upper part of the air exhaust ports, so as to act the function of top closing and heat preservation. Therefore, on one hand, the functions and effects of the protecting slag suspension, heat insulating plate suspension and heat generating agent adding of the original pouring are effectively replaced, which not only reduces the cost, but also eliminate the dust pollution of the protecting slag and the heat generating agent adding, and on the other hand, the space of the shrinkage cavity is filled by the liquid steel in the mould cover, so as to achieve the purposes that the shrinkage cavity of the steel ingot is reduced and the rate of the finished products of ingot steel is high. The utility model has the advantages of simple structure, safe and reliable using and good steel billet quality.
Description
Technical field
The utility model is a kind of improved ingot mould.
Background technology
Existing ingot slab mould, uncovered shape hot top rapid heat dissipation is worn in the upper end, and heat accumulation is few; covering slag produces a large amount of dust when not only pouring into a mould, the severe exacerbation production environment, and also the residual shrinkage cavity of steel ingot of cast is dark and permeate nonmetal impurities and the slag that dissociates; crop rate height when steel ingot cogging is rolling, billet yield is low.
Summary of the invention
The purpose of this utility model is a kind of twoport ingot slab mould of design, can greatly purify production environment during the cast steel ingot, reduces production costs, and the steel ingot shrinkage cavity of cast reduces, the billet yield height.
The purpose of this utility model is achieved like this: the cambered surface die cap that a band double cone shape exhaust outlet is installed in the die body upper end of existing ingot slab mould; when the cast steel ingot; red-hot molten steel enters in the ingot slab mould from the rise hole of ingot slab mould die body bottom; Bian Shangsheng; the limit with the normal temperature air upper punch in the die body by discharging in the double cone shape exhaust outlet; molten steel rises is to cambered surface die cap space; red-hot air-flow is with the rapid preheating of die cap; heat up and store heat; when molten steel injects double cone shape exhaust outlet; the free slag of separating out in the molten steel is concentrated the flat effect of playing the insulation of binding on double cone shape exhaust outlet top of applying; having substituted original cast steel ingot effectively need hang covering slag so on the one hand; hang heat-insulating shield; add the function and the effect of exothermic mixture; not only reduce production cost but also eliminated covering slag; the dust pollution of exothermic mixture; purified production environment; the red-hot heat of molten steel itself on the other hand; the heat that the cambered surface die cap stores and the insulation useful effect of binding of free slag blanket; molten steel in the cambered surface die cap is incubated by force; the space of shrinkage cavity is filled up in slow cooling; reach the steel ingot shrinkage cavity and reduce the purpose that billet yield is high.
It is simple in structure that the utility model is carried the twoport ingot slab mould, safe and reliable, and the steel ingot shrinkage cavity of being poured into a mould reduces, the billet yield height.
Description of drawings
Fig. 1 is that the master that the utility model is carried the twoport ingot slab mould looks schematic diagram.
Fig. 2 is the schematic top plan view that the utility model is carried the twoport ingot slab mould.
Specific implementation method
From Fig. 1; among Fig. 2 as can be seen: a kind of twoport ingot slab mould of forming by die body 1; it is characterized in that installing a cambered surface die cap 2 on the top of die body 1; going to the bottom of this cambered surface die cap 2 is the hollow flat; its periphery and the corresponding driving fit in plane, die body 1 top; several limited blocks 5 of arranged outside of periphery; the top of cambered surface die cap 2 is provided with two or more conical exhaust outlets 3 and two suspension ring 4; die cap 2 is winched to die body 1 top by limited block 5 automatically behind the location; the rising mouth of red-hot molten steel from die body 1 bottom enters die body 1 inner the rising; red-hot air-flow is discharged the normal temperature air upper punch in the die body 1 from conical exhaust outlet 3; when molten steel rises during to the space of cambered surface die cap 2; red-hot air-flow is with die cap 2 rapid preheatings; heat and store heat; when molten steel rises enters in the conical exhaust outlet 3; the free slag of separating out in the molten steel concentrates flat applying on the top of exhaust outlet 3 to play the insulation effect that binds; hang covering slag when having substituted original cast steel ingot so on the one hand effectively; hang heat-insulating shield; add the function and the effect of exothermic mixture; not only reduced production cost; and eliminated covering slag; the pollution of exothermic mixture dust from flying; purified production environment; the red-hot heat of molten steel itself on the other hand; the heat that cambered surface die cap 2 stores and the insulation of binding of free slag; make insulation by force in the die cap 2; the liquid molten steel of slow cooling is filled up the shrinkage cavity of steel ingot; reach the steel ingot shrinkage cavity and reduce the purpose that billet yield is high.
Claims (2)
1, a kind of twoport ingot slab mould of being made up of die body (1) is characterized in that:
A, a cambered surface die cap (2) is installed on the top of die body (1), going to the bottom of this die cap (2) is the hollow flat, periphery of going to the bottom and the corresponding driving fit in die body (1) plane, top, several limited blocks of the arranged outside of following bottom perimeter (5), the top of die cap (2) are provided with two conical exhaust outlets (3) and two suspension ring (4).
