Abstract
The utility model discloses a detachable and replaceable composite steel ladle fabricated part which is characterized by comprising a steel backed face body and a steel oriented face body, wherein the steel backed face body and the steel oriented face body are tightly combined by a bulge and groove structure arranged on a split joint surface. The steel backed face body is formed by pouring and vibrating magnesium-aluminium or high-aluminium castable, has relatively low volume density, a light weight, high intensity and low heat conductivity coefficient, and can be kept for a long time and repeatedly used as a permanent layer; and the steel oriented face body is formed by pouring and vibrating corundum or spinel castable, is used for resisting to molten steel corrosion, has a compact structure, has strong resistance to high temperature, scouring resistance and corrosion resistance, and can be separately replaced when being seriously corroded. Therefore, the detachable and replaceable composite steel ladle fabricated part has the advantages of reducing the weight of a steel ladle, reducing consumption of a refractory material and implementing split replacement and repair.
Description
Technical field
The utility model belongs to technical field of ferrous metallurgy, is specifically related to refining production ladle fire-resistant prefabricated member in a kind of process for making.
Background technology
Along with developing rapidly of unsettingization of refractory material and smelting iron and steel refining techniques, use carbon-free high-grade castable to replace carbon-containing sintered brick masonry ladle to carry out the production of clean steel, its application is more and more extensive.But because the restriction of steel mill's environment and condition, ladle baking is pressed for time, and baking control is not rigorous etc., and phenomenon happens occasionally, and baking quality has directly affected the result of use of castable without effective guarantee.So, each refractory material enterprise sets about the oven dry link is put into production process from the construction use procedure, carry out moulding by casting and low-temperature bake processing at the castable production basis, make carbon-free fire-resistant prefabricated member, obtained than containing carbon brick and castable more high-quality, more stable, more long-lived result of use.However, the production of prefabricated component and use still are accompanied by some problems, need to be resolved hurrily.Because the moulding of prefabricated component, oven dry are rationally controlled and looked after, bulk density improves relatively, the overweight problem of ladle occurs easily, and the security of operation problem also receives much concern; Steel mill is in security consideration, does not always reach at thickness when declaring bag and just forces dismounting when design is used, and the refractory material waste is serious; In addition, prefabricated component be difficult for to be repaired, and usually moves the Bao Yihou dismounting of directly rolling off the production line, only under a few cases, mend by replacing a damaged part, but performance difficulty.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, and a kind of compound ladle prefabricated component of replaceable that can alleviate ladle weight, minimizing refractory consumption rate, can realize sectional repair is provided.
For achieving the above object, the utility model adopts following solution:
The compound ladle prefabricated component of a kind of replaceable is characterized in that: comprise back of the body steel face body and to steel face body, both combine closely by the protrusion and the groove structure that arrange on the split faying face.
The compound ladle prefabricated component of above-mentioned replaceable is characterized in that: the hot junction of described back of the body steel face body is faying face, equidistant uniform some perforation groove structures on the faying face.Back of the body steel face body uses magnalium matter or high alumina castable cast, vibration moulding, the bulk density less, and weight is lighter, and intensity height and thermal conductivity factor is lower can be used as that permanent layer keeps for a long time, Reusability.
The compound ladle prefabricated component of above-mentioned replaceable is characterized in that: described cold junction to steel face body is faying face, the perforation groove structures of equidistant uniform some and back of the body steel face body projective structure one to one on the faying face.Use corundum or the cast of spinel castable, vibration moulding to steel face body, be used for the opposing molten steel and corrode, compact structure, high temperature resistant, resistance to erosion, erosion resisting are strong, can replace separately when serious corroding.
The compound ladle prefabricated component of above-mentioned replaceable is characterized in that: along the equidistant in the same way even distribution of single line, distributed quantity is 1～10/m on faying face for described perforation groove structure and projective structure; Both quantity equate that the position is identical, and bore is consistent, tightly combination.
During construction, put first and build by laying bricks or stones back of the body steel face body, then will aim at the perforation groove structure insertion of carrying on the back steel face body to the projective structure of steel face body and get final product.
Compared with prior art, of the present utility model have a following advantage:
1, adopt the split composite construction, back of the body steel face body can Reusability, needn't overall pulling down, greatly saved the refractory material consumption, and avoided unnecessary waste.
2, back of the body steel face body and adopt different materials to make to steel face body has not only alleviated ladle weight, and heat conductivility improves, and the material of concentrated subtend steel face body is optimized, and waste is few, and cost performance is higher, and integrated cost reduces, and economic serviceability is strengthened greatly.
3, faying face concave-convex design, structure is firm stable, and security is higher.
4, replaceable design, for the maintenance of prefabricated component and repairing provide may.

The specific embodiment:
Embodiment 1:
As shown in Figure 1, the compound ladle prefabricated component of a kind of replaceable for ladle lining top plan view, back of the body steel face body 1 is by alumina-magnesia castable cast, shake table vibration moulding; To steel face body by alumina-spinelle matter castable cast, shake table vibration moulding; Back of the body steel face body 1 relies on the ladle girdle around building by laying bricks or stones during use, will insert to the projective structure 4 of steel face body 2 perforation groove structure 3 interior the getting final product of back of the body steel face body 1.
As shown in Figure 2, the compound ladle prefabricated component of a kind of replaceable for bottom of steel ladle longitudinal sectional drawing, back of the body steel face body 1 is by alumina-magnesia castable cast, shake table vibration moulding; To steel face body 2 by corundum-spinel pouring material cast, shake table vibration moulding; Back of the body steel face body 1 relies on the bag end and builds by laying bricks or stones during use, and will insert to the projective structure 4 of steel face body 2 can be firm fixing in the perforation groove structure 3 of back of the body steel face bodies 1; Remove residual fraction when serious to 2 erosions of steel face body, inserting in the groove 3 of carrying on the back steel face bodies 1 to steel face body 2 of more renewing gets final product.
