Insulation cover for sealing tank mouth of torpedo car

Abstract

The invention provides an insulation cover for sealing a tank mouth of a torpedo car, which can effectively reduce heat loss in a process of transporting hot metal. The insulation cover comprises a steel shell, honeycomb firebricks, annular cover plates, stepped holes, riveting pieces, positioning supports, an inner-layer refractory material, an outer-layer refractory material, rain baffling devices, an annular positioning piece, cuboid rib plates and U-shaped lifting lugs. The stepped holes formed in the insulation cover disclosed by the invention can stabilize the air pressure in a tank cavity and lower thermal shock on materials of the insulation cover on the premise of guaranteeing reduction of thermal radiation passing through the tank mouth to play a role of protection; the firebricks are in shapes of circular honeycombs, and made of refractory clays, thereby capable of having a thermal shunting effect to effectively alleviate the thermal shock on a cap body; the rib plates are arranged to reinforce the strength of the insulation cover so as to facilitate heat dissipation. The insulation cover disclosed by the invention is simple in structure, convenient to operate, capable of effectively reducing the thermal radiation of the tank mouth and obvious in energy-saving effect.

Description

technical field [0001] The patent of the present invention relates to a closing device for a tank mouth of a mixed iron vehicle, in particular to a thermal insulation cover for closing the tank opening of a mixed iron vehicle Background technique [0002] The mixed iron car is a special vehicle for transporting molten iron. However, a large part of the heat will be lost through the mouth of the mixed iron car whether it is during the operation of loading molten iron or during the waiting period of the empty tank. In order to reduce the temperature drop of molten iron and maintain the temperature of the tank lining, it is necessary to install a capping device at the tank mouth of the mixed iron car. "Steel" in April 2002, No. 4, Volume 37 "Analysis of Temperature Drop of Torpedo Tank Molten Iron", on page 14, it is proposed that the tank mouth closure can effectively prevent the temperature drop from being too large, but no specific tank mouth sealing device is provided.
