Description
Technical field
This utility model belongs to ladle lining fireproof material field, particularly relates to a kind of corundum spinel castable.
Background technology
Along with the development of modern steel industry, the smelting condition of ladle is the harshest, and the use condition of refractory material used by ladle liner is harsher, and the castable of tradition material cannot meet the demand of technological progress.So it is imperative to develop novel high-performance steel ladle casting material.Corundum-spinel castable is the new varieties grown up in recent years, and the high-temperature behavior good due to it is widely used.But existing corundum-spinel castable there is also following problem: 1, relatively low adhesive rate can make inner lining material easily ftracture at middle and late stage to come off；2, volume stability is poor；3, thermal shock resistance is more weak.
Summary of the invention
Thering is provided a kind of simple in construction, conservation in place of this utility model is intended to overcome the deficiencies in the prior art, adhesive rate is high, and volume stability is good, the corundum spinel castable that thermal shock resistance is strong.
For solving above-mentioned technical problem, this utility model is realized in.
Corundum spinel castable, including the first castable body and the second castable body；Described first castable body and the second castable body are fixedly connected through connecting stake；First castable body and the second castable body are hexahedron structure；Sidewall at described first castable body and the second castable body is provided with through hole.
As a kind of preferred version, this utility model is fixed with parallel grid in the top and bottom of described first castable body and the second castable body.
This utility model simple in construction, is designed by the combination hexahedron shape structure of castable body and configures lateral through aperture in addition, make pouring technology save substantial amounts of raw material resources.The features such as it addition, this utility model also has adhesive rate height, volume stability is good, and thermal shock resistance is strong.
Accompanying drawing explanation
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.Protection domain of the present utility model is not only limited to the statement of following content.
Fig. 1 is this utility model overall structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, corundum spinel castable, including: the first castable body 1 and the second castable body 2；Described first castable body 1 is fixedly connected through being connected stake 3 with the second castable body 2；First castable body 1 and the second castable body 2 are hexahedron structure；Sidewall at described first castable body 1 and the second castable body 2 is provided with through hole 4.
For strengthening adhesive force, this utility model is fixed with parallel grid 5 in the top and bottom of described first castable body 1 and the second castable body 2.
Strength at normal temperature after 1500 DEG C × 3h of this utility model burns is 13～18MPa, and compressive resistance is 89～109MPa；After 1100 DEG C of water-cooleds five times, rupture strength conservation rate is 17～25%；1500 DEG C of Static crucible method anti-slag experiment erosion index are 8～14%；Penetration index is 31～34%.
It is appreciated that, above with respect to specific descriptions of the present utility model, it is merely to illustrate this utility model, and it is not limited to the technical scheme described by this utility model examples of implementation, it will be understood by those within the art that, still this utility model can be modified or equivalent, to reach identical technique effect；Needs are used, all within protection domain of the present utility model as long as meeting.
Claims (2)
1. corundum spinel castable, it is characterised in that include the first castable body (1) and the second castable body (2)；Described first castable body (1) is fixedly connected through being connected stake (3) with the second castable body (2)；First castable body (1) and the second castable body (2) are hexahedron structure；Sidewall at described first castable body (1) Yu the second castable body (2) is provided with through hole (4).
