Embodiment 1
[0035] A furnace eyelet assembly, the structure of which is as follows figure 1 As shown, the inner diameter of the furnace eye is 80 cm and the length is 65 cm. Inside the furnace eye is the outflow channel of the molten liquid: the copper cooling kit is placed outside the furnace eye and forms a closed space with the furnace eye. The closed space is Cooling water flow channel; the first inlet and the first outlet are located on the side wall of the cooling kit, the cooling water is injected into the closed space from the first inlet to cool the furnace eye, and the vaporized water vapor of the cooling water is discharged from the first outlet , wherein the distance between the central axes of the first inlet and the first outlet is 140 cm. Therefore, by setting the cooling kit and using the cooling kit to lower the temperature of the furnace eye, the high temperature resistance of the furnace eye assembly is significantly improved, and can withstand a high temperature of 150...

The invention discloses a hearth assembly. The hearth assembly comprises a hearth, a cooling jacket component, a first inlet and a first outlet, wherein an outflow runner of molten liquid is defined in the hearth; the cooling jacket component is arranged at the outer part of the hearth in a sleeving manner and forms a sealed space with the hearth, and a first cooling liquid flow channel is defined in the sealed space; the first inlet is positioned on the cooling jacket component and used for filling the sealed space with first cooling liquid; and the first outlet is positioned on the cooling jacket component and used for discharging vaporized first cooling liquid. The high temperature resistance of the hearth assembly is greatly improved, and the service life is long. Besides, the hearth assembly is low in cost, easy to use and high in safety.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to an electric furnace, and more specifically to a furnace eye assembly. Background technique [0002] At present, the holes of the electric furnace are directly discharged, and it is difficult to accurately control the flow and velocity of the melt in the electric furnace. Moreover, the existing furnace blocking device uses yellow mud and asbestos blocking furnace cover, which is manually operated, and there are disadvantages such as operating procedures for the furnace blocking device, which are cumbersome, poor operating environment, dangerous, not resistant to high temperature, incapable of precise control, and high in cost. [0003] Therefore, the furnace eye of the electric furnace needs to be improved. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invent...
