Abstract
The invention discloses an ingot mould repair method. The ingot mould repair method is characterized in that a plastic refractory material and a binding agent are uniformly mixed in certain proportion; cold-state or thermal-state repair is carried out on cracks; and the cracks are filled, are smoothed, and are put into use after being used. According to the ingot mould repair method disclosed by the invention, the plastic refractory material is adopted to carry out repair on cracks, and a repaired ingot mould can be continuously used, so that using times of the ingot mould are increased, steel ingot quality is guaranteed, and production cost is reduced.
Description
Technical field
The present invention relates to ingot mould method for repairing and mending.
Background technology
In steel ingot production process, steel ingot die needs Reusability, and belong to easily-consumed products, in steel ingot manufacturing cost, the ratio of ingot mould expense is not little.After ingot mould (chassis) uses certain heat, mould bottom outlet position, inwall etc. there will be cracking phenomena, and crackle acquires a certain degree, and mould just can not throw use again.One is affect ingot quality, and two is demoulding difficulties.
Summary of the invention
The object of the present invention is to provide a kind of ingot mould method for repairing and mending, adopt plastic refractory material, repair cracks, the ingot mould after repairing can continue to use, and extends ingot mould access times, ensures ingot quality, reduces production cost.
For achieving the above object, technical scheme of the present invention is a kind of ingot mould method for repairing and mending of design, and mixed by a certain percentage with binding agent by plastic refractory material and mix thoroughly, fracture carries out cold conditions or hot patching, is tamped in crack, floating, comes into operation after drying.
Preferably, the heatproof temperature of described plastic refractory material is not less than 1650 DEG C.
Advantage of the present invention and beneficial effect are: provide a kind of ingot mould method for repairing and mending, adopt plastic refractory material, repair cracks, and the ingot mould after repairing can continue to use, and extends ingot mould access times, ensures ingot quality, reduces production cost.
The present invention has following features:
1. the repairing of ingot mould, chassis crack re-uses, and extends ingot mould access times, and reduce production cost, ingot mould cost is about 80-100 yuan/ton of steel, uses once, considerable benefit more.
2. re-use after the repairing of ingot mould, chassis crack, the surface quality of steel ingot (scab, crackle) and inherent quality (ingot mould fusing forms Non-metallic inclusion) can be avoided.
3. being re-used by the repairing of ingot mould, chassis crack, ingot mould, chassis can being reduced for depositing.
4., by re-using after the repairing of ingot mould, chassis crack, there will not be that ingot mould and steel ingot are adhered and the demoulding is difficult.
5. molten steel no longer penetrates into crackle depths, and cracks because of high temperature melting after infiltration molten steel, can not cause ingot mould melting loss and be difficult to the demoulding.
6. method for repairing and mending, simple, quick, easy to operate.
Accompanying drawing explanation
Fig. 1 is the photo repairing front mould bottom outlet position;
Fig. 2 is the photo repairing rear mold bottom outlet position;
Fig. 3 is the photo using rear mold bottom outlet position.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
A kind of ingot mould method for repairing and mending, mixed by a certain percentage with binding agent by plastic refractory material and mix thoroughly, fracture carries out cold conditions or hot patching, is tamped in crack, floating, comes into operation after drying.
The heatproof temperature of described plastic refractory material is not less than 1650 DEG C.
Repair many places, front mould bottom outlet position cracking, as shown in Figure 1;
Repair rear mold bottom outlet position as shown in Figure 2;
Use rear mold bottom outlet position as shown in Figure 3.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. ingot mould method for repairing and mending, is characterized in that, mixed by a certain percentage with binding agent by plastic refractory material and mix thoroughly, fracture carries out cold conditions or hot patching, is tamped in crack, floating, comes into operation after drying.
