In steelmaking, ironmaking, coking and other smelting industry, high temperature furnace temperature is generally in 1000 ℃ ~ 2000 ℃, at this temperature in front of the furnace work position, heat radiation intensity is very big, according to medical science research: under the action of high temperature and heat radiation, cerebral cortex regulation center of excitement increased, so that the central nervous system movement function is suppressed, the accuracy, coordination, attention and reaction ability to reduce during operation, more prone to accidents. So high temperature equipment should use good effect of nano thermal insulation board for heat insulation.

Because the furnace temperature of metallurgical industry such as steel-making is very high, if the heat insulation effect is not good, the equipment outside will have a high temperature, under the condition of more equipment, the temperature in the whole environment will be very high, affect the safety of staff. By use that nano heat insulation plate as the heat insulation layer, the heat dissipation of the equipment can be greatly reduce, the external temperature of the equipment can be reduced, and the temperature of the working environment can not cause harm to people.
