Hot metal ladle and torpedo can are the key equipment to convey the molten iron between iron-making production and steel-making production. Generally, it is necessary for long distance to transport and for long time to wait for. If It is of significance to apply microporous thermal insulation material:

(1)Reduce heat loss, raise the molten iron temperature when it arrives at the steel mill improve the content of steel scrap and pig iron to reduce the cost of steel-making;

(2) Make the shell temperature of hot metal ladle and torpedo tank fall down, increase the useful life;

(3) Reduce the temperature fall of molten iron transportation and beneficial to production organization and ensure the temperature of molten iron;

(4).Prevent hot metal ladle from slag-bonding, improve the recovery rate of molten iron.
