Abstract
The utility model discloses a device for improving a steel ingot solidification tissue structure method. The device comprises an ingot mould and an ingot mould base plate, wherein a casting channel is arranged in the ingot mould base plate; a vibration device is arranged at the upper part or the lower part of the ingot mould base plate; the base plate is subjected to vibration in a step of solidification of molten steel and drives the ingot mould and the molten steel in the ingot mould to vibrate together so as to make the interior solidification tissue of a steel ingot become dense and uniform; and the mechanical properties of a steel plate rolled by the steel ingot and produced through the mode are excellent, and the interior flaw detection quality is good. The vibration device is arranged at the upper part or the lower part of the ingot mould base plate and is subjected to heat insulation protection to prevent the vibration device from being baked and damaged due to the high-temperature ingot mould, and the base plate is subjected to vibration in the step of solidification after the molten steel is injected and drives the ingot mould to vibrate during the vibration of the base plate, so that the thermal motion of the molten steel in the ingot mould is strengthened.
Description
Technical field
The utility model relates to the pouring device that uses in the steel-making, is specifically related to a kind of device that is used to improve ingot solidification institutional framework method.
Background technology
At present, which kind of explained hereafter no matter conventional moulded steel take, and all can't remedy or effectively solve the defective of steel ingot center porosity and segregation fully.Cause the steel ingot internal soundness to have defective thus, rolling slab flaw detection qualification rate hangs down and a series of problems such as lumber recovery is low.
And when adopting directional solidification or electroslag remelting production technology production die casting clean steel, low because of its production efficiency, cost is high and the substance restriction, still can not satisfy the requirement of the extra heavy super-thick steel plate of large-scale production.
Summary of the invention
A series of shortcomings such as, cost height low for loose, the segregation defective that overcomes that conventional die casting has and directional solidification, electroslag remelting clean steel efficient, for this reason, the purpose of the utility model provides a kind of device that is used to improve ingot solidification institutional framework method.
For achieving the above object; The technical scheme that the utility model is taked is that this device that is used to improve ingot solidification institutional framework method comprises ingot mould and ingot mould chassis; Ingot mould is established pouring channel in the chassis, is provided with vibrating device on top, ingot mould chassis or bottom, in the solidification stages of molten steel the chassis is vibrated; The chassis drives the also vibration together of molten steel in ingot mould and the ingot mould; Make the solidified inside tissue of steel ingot become fine and close and even, the steel ingot rolled plate each item mechanics that adopts this mode to produce is excellent, and inner flaw detection quality is good.
The utility model solves the technical scheme that its technical problem adopted: on the chassis of ingot mould or below install vibrating device; And it is carried out insulated heat avoid the high temperature ingot mould to bake bad vibrating device; Annotating the complete after coagulation stage at molten steel again vibrates the chassis; Drive the ingot mould vibration when chassis vibrates, thereby strengthened the warm-up movement of molten steel in the ingot mould.
Because molten steel is in the cooled and solidified process, crystallization direction is to expand along the thermograde direction, ecto-entad, carries out the forming core crystallization in the end and the branch place of column crystal from bottom to top.After molten steel vibrated, can strengthen molten steel flowing in ingot mould, the flow field and the temperature field of improving molten steel, and the solidification front crystallization of molten steel improved increase the forming core probability of molten steel, make the solidified structure of molten steel become fine and close with evenly.
The beneficial effect of the utility model is; Improve steel ingot inner segregation and porousness; Can produce the uniform steel ingot of steel ingot dense internal organization thus; But adopt steel ingot rolling thickness that the method produces more than 200mm, protect the low alloy steel plate of one-level flaw detection, simultaneously each item mechanical property of steel plate especially the toughness of steel plate be significantly improved.
Description of drawings
The utility model is further specified with implementing to intend below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1. ingot mould, 2. ingot mould chassis, 3. vibrating device.
The specific embodiment
Referring to accompanying drawing, the device that the utility model is said to be used to improve ingot solidification institutional framework method comprises ingot mould 1 and ingot mould chassis 2, and ingot mould is established pouring channel in the chassis; On top, ingot mould chassis or the bottom be provided with vibrating device 3; Solidification stages at molten steel is vibrated the chassis, and the molten steel in chassis drive ingot mould and the ingot mould is vibration together also, makes the solidified inside tissue of steel ingot become fine and close and even; The steel ingot rolled plate each item mechanics that adopts this mode to produce is excellent, and inner flaw detection quality is good.
Making vibrating device according to above-mentioned designing requirement is installed on the ingot mould chassis; Solidification stages after pouring molten steel finishes; As required can be to the steel ingot chassis in addition up and down or side-to-side vibrations in certain setting time section, thus impel the molten steel of ingot mould in ingot mould, to strengthen mobile.
