Abstract
An improved iron tapping channel comprises a U-shaped channel body, wherein the channel body sequentially consists of a working layer, a permanent layer and a shell from inside to outside, wherein the shell is a hollow cavity, the shell is provided with a water inlet and a water outlet, cooling water is filled inside the shell, a molten iron layer is condensed on the surface of the working layer, so that the service life of the working layer is greatly prolonged, a great amount of toxic gases and powder layers caused by direct contact of the molten iron and the working layer can be effectively prevented, and the operation safety of the workers can be improved.
Description
Technical field
The utility model relates to the steelmaking equipment of field of steel-making, relates in particular to a kind of improved casting house.
Background technology
Casting house is that the molten steel of blast furnace white silk rings territory widespread goes out furnace apparatus; Present casting house on the market generally only comprises permanent layer and working lining, and molten iron is when flowing out through casting house, because high temperature produces a large amount of toxic gas and dust; Working environment and the bigger influence of healthy generation to the workshop workman; And owing to the wearing and tearing and the attenuation that is easy to cause refractory material for working layer of washing away of high temperature liquid iron, shorten the work-ing life of casting house, reduce working efficiency.
Summary of the invention
The utility model is not enough to prior art, and a kind of long service life is provided, and reduces the improved casting house of gas and dust pollution.
The utility model is for solving the problems of the technologies described above; Following technical scheme is provided: a kind of improved casting house; Comprise U-shaped ditch body; Described ditch body is followed successively by working lining, permanent layer and shell from inside to outside, it is characterized in that shell is a hollow cavity, and shell is provided with water-in and water outlet.
Further improve as the utility model, water-in is arranged on shell one lateral upper front end, and water outlet is arranged on the bottom of shell another side, improves the service efficiency of recirculated water.
As the further improvement of the utility model, shell is the U cavity of fitting with permanent layer.
For better explaining the technical scheme of the utility model; Below introduce the principle of work of the utility model in detail: after molten steel burns the injection casting house; In the U-shaped shell, squeeze into recirculated cooling water through water-in with water pump, because the cooling effect of shell water coolant effectively reduces the surperficial temperature of working lining; Make the working lining surface temperature be lower than the coagulation temperature of molten iron; Molten iron becomes the immobilising ladle heel layer of one deck in the surface condensation of casting house working lining, thereby prevents that effectively refractory material for working layer from wearing and tearing owing to molten iron washes away, and prolongs working lining work-ing life.
The beneficial effect of the utility model: the utility model is through inject water coolant in the enclosure; Make working lining surface condensation one deck ladle heel layer; Prolonged the work-ing life of working lining greatly; And prevent that effectively molten iron and working lining from directly contacting a large amount of toxic gases and the bisque of generation, improved the security of workman's operation.
