Hot-metal bottle is the splendid attire elevated temperature vessel blast-melted with conveying, at present, hot-metal bottle tank mouth inner lining structure of fire-proof is comprised of permanent layer and working lining, wherein, the permanent layer refractory material is light fire brick or castable, refractory material for working layer is clay brick, high-alumina brick, Al2O3C Bricks, aluminum-silicon carbide brick, owing to contain iron at hot-metal bottle, the fluctuation of the splash of slag and molten iron and molten iron level in the transportation, cause hot-metal bottle tank mouth dry slag serious, especially bear the hot-metal bottle of desulfurizing iron pre-cleaning, splash in the sweetening process and liquid fluctuating phenomenon are even more serious, dry slag thickness reaches 300～500mm, when tank mouth dry slag area reaches 80%, to have a strong impact on the normal operation of hot-metal bottle, must collude the slag cleaning, but because dry slag and refractory material working lining surface conjunction are tight, cause the distortion of the breakage of refractory material working lining and tank oral thermometer face metal platen, need rebuild maintenance; Within the hot-metal bottle military service phase, dry slag is cleared up with colluding slag frequently, causes the repeatedly damaged and repairing of refractory material working lining, not only causes the rising of refractory consumption rate cost, has also increased simultaneously the hot-metal bottle maintenance workload, has worsened working environment.For the problems referred to above, domestic scholars is from the angle of dry slag isolation with refractory material working lining globality, research has also been used coating against binding slags and tank mouth castable refractory working lining, and obtained the effect of the deformation extent of the breakage that reduces the refractory material working lining and metal casing in actual production, but the repair maintenance amount of working lining and metal casing is still larger.
Summary of the invention
The purpose of this utility model be exactly to provide that a kind of simple in structure, resisting breakage ability is strong, long service life, hot-metal bottle tank mouth inner lining structure that maintenance cost is low.
For achieving the above object, the hot-metal bottle tank mouth inner lining structure that the utility model is designed, comprise the permanent layer and the working lining that are arranged on metal tank skin inboard, its special character is, the end face of described permanent layer and working lining is pressed successively high-low staggered-floor and is arranged, be provided with tank mouth refractory lining on described permanent layer and the working lining end face, described tank mouth refractory lining is by being fixed on the metal anchorage on the metal tank skin tank mouth and the heavy castable refractory is integrated poured forms, its top is concordant with the tank mouth of metal tank skin, and its cross section is the scalariform of falling from power.
As preferred version, described metal anchorage is comprised of metal foil and U-shaped rod iron, it is inboard that described metal foil is evenly arranged in the metal tank skin, described U-shaped rod iron is arranged symmetrically on the metal foil two sides, the U-shaped face of described U-shaped rod iron is axially vertical with hot-metal bottle, one side of described U-shaped rod iron is fixed on the metal tank skin, and the base of described U-shaped rod iron is fixed on the metal foil.
As preferred version, height h1=300 ~ 400mm that described tank mouth refractory lining is combined with the metal tank skin; Height h2=300 ~ 400mm that described tank mouth refractory lining is combined with permanent layer.
The utility model is by the structural design of hot-metal bottle upper inner liner, strengthened between liner heavy castable refractory and the tank skin bond strength with in conjunction with compactness, improved the resisting breakage ability of tank mouth refractory lining, structural design by lower inner liner, strengthen the thermal and insulating performance of tank mouth refractory lining, improved simultaneously the comprehensive integral of hot-metal bottle tank mouth refractory lining; By the metal anchorage structural design that is formed by metal foil and U-shaped rod iron, strengthened the strength and stiffness of metal anchorage self, improved the anti-mechanical damage integration capability of hot-metal bottle tank mouth refractory lining; By cancelling the in the past metal platen of hot-metal bottle tank mouth refractory lining upper surface, the metal platen distortion of having avoided the dry slag cleaning to bring.The utility model is by the comprehensive effect of above-mentioned measure, reaches to prolong hot-metal bottle tank mouth refractory lining service life, reduce maintenance cost, improve the purpose of all transfer efficients.
