Because the temperature of zinc liquid is 450 degrees, the temperature above the cover plate is generally below 60 degrees, and personnel operation is basically no problem. Because the radiation heat transfer is related to the 4th power of temperature, therefore for 680 degrees aluminum silicon pot, such cover plate obviously can not be used, the temperature above the cover plate is above 100 degrees, personnel scalds foot, cannot operate. And the general carbon steel is exposed to high temperature for a long time, and the one facing aluminum liquid will oxidize at high temperature, delamination and peeling, which affects the strength of the cover plate. At the same time, the cover plate will also be bent at high temperature, which is extremely unsafe.

[0003] In view of the above problems, in order to meet the production needs, only the heat resisting heat preservation layer can be added on the original cover plate, so that the thickened cover plate can barely meet the needs of 680 degrees aluminum silicon pot, but the thickness is relatively thick. Because the furnace grate needs to be placed up and separated from the liquid surface when replacing the furnace grate, and needs to be higher than the pot edge by a certain distance, if the thickness of the cover plate is relatively thick, the space for the furnace grate to swing is large, so that the cover plate can be inserted below. In this way, it is not convenient to open and close, and it is relatively easy to cause safety accidents, and the requirements for the swinging mechanism and the expansion joint are high, so a thin cover plate that can effectively reduce heat is needed to ensure the needs of the operating personnel to replace the furnace grate. SUMMARY

[0004] The utility model discloses a kind of aluminum silicon pot cover plates with cooling, the cover plate is good in heat insulation, small in thickness, can meet the replacement operation demand of furnace grate, guarantee the work safety of staff.

[0005] The technical scheme adopted by the utility model is as follows: an aluminum silicon pot cover plate with cooling, characterized by: including channel steel frame, multiple partitions, multiple steel pipes, heat preservation cotton, top plate and bottom plate;Multiple partitions are fixed at the upper part in the channel steel frame with interval, multiple steel pipes are arranged with interval, each steel pipe is fixed in multiple partitions and channel steel frame by being penetrated, and air injection pipe is further arranged in each steel pipe;The top plate and the bottom plate are respectively arranged on the top surface and the bottom surface of the channel steel frame and are fixedly connected by anchor nail, and the channel steel frame is filled with heat preservation cotton.

[0006] Further, the top plate is a pattern plate.

[0007] Furthermore, the base plate is a smooth stainless steel plate. Preferably, the smooth stainless steel plate is composed of multiple small smooth stainless steel plates.

[0008] Furthermore, the partition has 5 sections. The steel pipe has 3 sections.

[0009] The beneficial effects of this utility model are: the above-mentioned structure provides good heat insulation and a small thickness, which can meet the needs of grate replacement operations. Simultaneously, an air nozzle is designed inside the steel pipe, which, during use, uses compressed air to drive airflow within the steel pipe, cooling the pipe and maintaining its temperature below 150 degrees Celsius. This ensures the steel pipe will not bend or deform, has sufficient supporting strength, and guarantees operational safety. Attached Figure Description
