Technical Field
The utility model belongs to the metallurgical equipment field, concretely relates to middle package masonry structure.
Background
In the continuous casting process, a tundish is a refractory container used in short-flow steelmaking, and firstly receives molten steel poured from a ladle and then distributes the molten steel to each crystallizer through a tundish nozzle. The continuous casting tundish has the function of stabilizing the temperature of molten steel, so that molten steel inclusions float upwards, and the smooth continuous casting process can be ensured when molten steel is lacked or the continuous casting tundish is replaced in a short time. With the optimization of the continuous casting process and the improvement of the quality requirement of continuous casting billets, the continuous casting tundish is developed into molten steel refining terminal equipment, and plays an important role in the smooth continuous casting.
The continuous casting tundish structure in the continuous casting production at present has poor heat insulation effect, influences the quality of a casting blank and cannot meet the normal working requirement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, providing a middle package masonry structure, can improve the heat preservation condition of middle package, package process temperature drop in the middle of reducing to improve the casting blank quality.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
a tundish masonry structure comprises a heat insulation layer, a permanent layer and a working layer, wherein the heat insulation layer, the permanent layer and the working layer are sequentially formed from outside to inside, the heat insulation layer belongs to the outermost layer, the working layer is the innermost layer, the middle layer is formed by the heat insulation layer and the permanent layer, the heat insulation layer is connected with the heat insulation layer, and the permanent layer is connected with the working layer.
Preferably, the thickness of the heat insulation layer is 10-30 mm.
Preferably, the heat insulating layer is made of asbestos boards, insulating bricks or light castable.
Preferably, the heat insulation layer is a 5mm nanometer heat insulation plate.
Preferably, the thickness of the permanent layer is 100-200 mm.
Preferably, the permanent layer is made of clay bricks.
Preferably, the thickness of the working layer is 20-50 mm.
Preferably, the working layer is made of heat insulation plate.
The utility model realizes the optimization of the tundish masonry structure by adopting a four-layer structure of a heat insulation layer, a thermal insulation layer, a permanent layer and a working layer, wherein the heat insulation layer is close to the tundish steel shell to insulate the molten steel and reduce the temperature drop of the molten steel in the pouring process; the heat insulation layer is arranged between the heat insulation layer and the permanent layer, and the nano heat insulation plate is adopted, so that the heat insulation effect of the tundish structure is improved; the permanent layer is contacted with the heat insulation layer, so that the effect of safe heat insulation is achieved; the working layer is in contact with the molten steel, is a key part, and adopts heat insulation materials, so that the heat dissipation of the molten steel is reduced.
Scheme more than adopting, the utility model relates to a middle package masonry structure can improve the heat preservation condition of middle package, reaches middle package process temperature drop to extra-high casting blank quality.
