Abstract
The utility model proposes a kind of combined type ladle lashed area prefabricated section brick, comprising: interior brick body and outer brick body, interior brick body is arranged at the inside of outer brick body; Interior brick body and outer brick body are by Low Cement Castable moulding by casting, the utility model adopts combined type ladle lashed area prefabricated section brick, middle use low-carbon corundum-spinel brick, surrounding and bottom adopt low cement corundum castable, make the prefabricated section brick of entire combination have good thermal shock resistance, antiscour and hole aggressivity, there is again higher normal temperature strength, be convenient to transport and construction, high life, cost-saving, reduce labor strength.
Description
Technical field
The utility model relates to a kind of iron and steel metallurgical industry ladle lashed area prefabricated section brick, particularly relates to a kind of combined type ladle lashed area prefabricated section brick that largely can improve bottom of steel ladle service life.
Background technology
Ladle bottom impact area of steel ladle is positioned at the centre position, bottom of ladle, is subject to direct impact and the erosion of molten steel, has very high anti-erosion and scour resistance, simultaneously, ladle is again the bearing container of molten steel, is subject to cold and hot replacing, has good thermal shock resistance again.Along with the development of steel industry and continuous casting technology, the long-life ladle of Large Copacity high-quality also more and more comes into one's own.In order to cost-saving, reduce refractory brick to the pollution of molten steel recarburization, Non-carbonized refractory material is subject to increasing application, ladle integral pouring, and impact zone adopts one of the measure of prefabricated section brick Large Copacity ladle reform.
Along with the appearance of Large Copacity ladle and clean steel, variety steel, to ladle material and the requirement in life-span also more and more higher, but, even if impact zone prefabricated section brick is thicker than the material feeding of bag bottom pour mold, also easily there is the phenomenon in hole Large Copacity ladle bottom impact area of steel ladle using the later stage, and antiscour and hole aggressivity poor, cost is high.
Utility model content
The utility model proposes a kind of combined type ladle lashed area prefabricated section brick, solve the technical problem that ladle lashed area of the prior art its life-span of prefabricated section brick is low and cost is high.
The technical solution of the utility model is achieved in that
A kind of combined type ladle lashed area prefabricated section brick, comprising: interior brick body and outer brick body, interior brick body is arranged at the inside of described outer brick body; Interior brick body and outer brick body are by Low Cement Castable moulding by casting.
Preferably, outer brick body inside is provided with cavity, and interior brick body comprises many rows and builds brick by laying bricks or stones, builds brick by laying bricks or stones and is fixed on equably in cavity.
Preferably, interior brick body is magnesium carbonaceous or magnalium carbon-spinel matter brick body; Outer brick body is corundum or corundum spinel brick body.
The utility model has higher intensity, stability and antiscour aggressivity, low-carbon magnesium Alumina spinel brick has good thermal shock resistance, antiscour erosion resisting is good, and with the Low Cement Castable that cement combines, there is higher normal temperature elevated temperature strength, low-carbon corundum-spinel brick is built by laying bricks or stones in the middle of prefabricated section, bottom and surrounding use castable, and the resistance to material of split is combined into as a whole, combines low-carbon corundum-spinel brick and low cement corundum castable advantage separately.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only that principle of the present utility model is described, for those of ordinary skill in the art, under the prerequisite not paying creative work, the operation principle of this patent is had gained some understanding.
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the know-why in the utility model embodiment is clearly and completely described.Based on the know-why in the utility model, those of ordinary skill in the art are not making the every other embodiment based on this know-why obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of combined type ladle bottom impact area of steel ladle of the present utility model prefabricated section brick, comprise: interior brick body 2 and outer brick body 1, interior brick body 2 and outer brick body 1 are by Low Cement Castable moulding by casting, and be finally combined into as a whole, interior brick body 2 is different with outer brick body 1 molding mode, interior brick body 2 adopts inside to build brick by laying bricks or stones, use machine pressure carbonaceous article, uses magnesium carbonaceous or magnalium carbon-spinel matter, can play its thermal shock resistance, corrosion resistance and scour resistance to greatest extent; Outer brick body 1 adopts outside cast pre-formed, use corundum or corundum spinel, have higher normal temperature strength, the service life of ladle bottom impact area of steel ladle prefabricated section brick can be improved significantly, interior brick body 2 is connected by Low Cement Castable with outer brick body 1, without any gap, as same entirety, ensure the safe handling of ladle bottom impact area of steel ladle, pour into a mould prefabricated profiled prefabricated section brick cup intensity high, thickness is little, and curing time is short, can not burst by quick baking.
Preparation process of the present utility model is: design impact zone prefabricated section bricks die as requested, inner mechanical pressing, and outside cast is pre-formed, the inner pressed machine brick of first mechanical pressing, the bottom of pouring precast block brick, controls castable amount of water, use shaking platform vibrates, surfacing; Build inner pressed machine brick by laying bricks or stones, cast is space around, uses vibrating head vibration, makes whole ladle bottom impact area of steel ladle prefabricated section brick as integrated poured, very close to each other.
The utility model adopts the refractory brick of magnesium carbon or magnalium carbon-spinel matter mechanical pressing to have very high thermal shock resistance, anti-erosion and scour resistance; And the prefabricated profiled corundum of low cement casting has higher normal temperature, elevated temperature strength, ladle bottom impact area of steel ladle prefabricated section brick volume ratio is larger, ladle bottom impact area of steel ladle prefabricated section brick is divided into interior brick body 2 and outer brick body 1 two parts, in conjunction with machine pressure magnesium carbon or magnalium carbon-spinel matter and prefabricated profiled both corundums combination property of low cement casting, ladle bottom impact area of steel ladle prefabricated section brick completely restricted extension pressure brick masonry, outer part cast is pre-formed.Inside and outsidely to be ined succession an entirety by moulding by casting, such ladle bottom impact area of steel ladle prefabricated section brick i.e. concrete thermal shock resistance preferably, and anti-erosion, scour resistance, have again higher normal temperature strength.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
