Abstract
The invention relates to a heat-insulating plate which comprises a plurality of metal layers and a plurality of heat-insulating layers, wherein the heat-insulating layers are arranged among the metal layers; and the heat-insulating layers comprise a plurality of heat-insulating units with hollow structures. The heat-insulating plate has good heat-insulating property and is particularly suitable for the metallurgical industry. A heat-insulating material is filled in the heat-insulating units and can further improve the heat-insulating property. The invention also provides a manufacturing method of the heat-insulating plate, which comprises the following steps: forming the heat-insulating layers with a plurality of heat-insulating units; and fixedly connecting the metal layers respectively at the upper side and the lower side of the heat-insulating layers. The strength of the heat-insulating plate can be further improved by fixedly connecting the heat-insulating layers with at least one of the metal layers by explosive welding.
Description
technical field [0001] The invention relates to a heat shield and a manufacturing method thereof, in particular to a heat shield used under high temperature conditions in the metallurgical industry and a manufacturing method thereof. Background technique [0002] Insulation boards, especially those used in high temperature conditions in the metallurgical industry, such as stovetops, etc., in order to achieve a good heat insulation effect, the heat insulation boards are usually very thick, which is not conducive to installation and use, and wastes materials. In addition, in the prior art, heat insulating materials such as plastics are usually used as the core layer, and are arranged between the metal layers by bonding or other means to form the whole heat insulating board. The heat insulation effect of this heat insulation board is not good, and the strength of bonding and fixing is not high, and the connection method is unreliable. Contents of the invention [0003] In or...
