Background technology
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 made up of permanent layer and working lining, wherein, 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 containing iron at hot-metal bottle, the splash of slag and molten iron and the fluctuation of molten iron level in transportation, cause hot-metal bottle tank mouth dry slag serious, especially bear the hot-metal bottle of desulfurizing iron pre-cleaning, splash in sweetening process and liquid fluctuating phenomenon are even more serious, dry slag thickness reaches 300~500mm, in the time that tank mouth dry slag area reaches 80%, the normal operation of hot-metal bottle will be had a strong impact on, must hook slag cleaning, but due to dry slag and refractory material working lining surface conjunction 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 and the cleaning of hook slag frequently, causes the damaged and repairing repeatedly of refractory material working lining, not only causes the rising of refractory consumption rate cost, has also increased hot-metal bottle maintenance workload simultaneously, has worsened working environment.For the problems referred to above, domestic scholars is the angle with refractory material working lining globality from dry slag isolation, study and applied coating against binding slags and tank mouth castable refractory working lining, and in actual production, obtained the effect that reduces the breakage of refractory material working lining and the deformation extent of metal casing, but the repair maintenance amount of working lining and metal casing is still larger.
Summary of the invention
Object of the present invention 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 present invention is designed, comprise the permanent layer and the working lining that are arranged on metal tank skin inner side, its special character is, the end face of described permanent layer and working lining is pressed successively high-low staggered-floor and is arranged, on described permanent layer and working lining end face, be provided with tank mouth refractory lining, described tank mouth refractory lining is by being fixed on the metal anchorage on metal tank skin tank mouth and 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 made up of metal foil and U-shaped rod iron, described metal foil is evenly arranged in metal tank skin inner side, described U-shaped rod iron is arranged symmetrically on 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 metal tank skin, and the base of described U-shaped rod iron is fixed on metal foil.
As preferred version, height h1=300 ~ 400mm that described tank mouth refractory lining is combined with metal tank skin; Height h2=300 ~ 400mm that described tank mouth refractory lining is combined with permanent layer.
The present invention is by the structural design of hot-metal bottle upper inner liner, strengthened bond strength between liner heavy castable refractory and tank skin with in conjunction with compactness, improve the resisting breakage ability of tank mouth refractory lining, by the structural design of lower inner liner, strengthen the thermal and insulating performance of tank mouth refractory lining, improved the comprehensive integral of hot-metal bottle tank mouth refractory lining simultaneously; By the metal anchorage structural design being formed by metal foil and U-shaped rod iron, strengthen the strength and stiffness of metal anchorage self, improve the anti-mechanical damage integration capability of hot-metal bottle tank mouth refractory lining; By cancelling the metal platen of hot-metal bottle tank mouth refractory lining upper surface in the past, the metal platen distortion of having avoided dry slag to clear up bringing.The present invention is by the comprehensive effect of above-mentioned measure, reaches to extend hot-metal bottle tank mouth refractory lining service life, reduce maintenance cost, improve the object of all transfer efficients.
