The invention relates to a torpedo pot liner structure and torpedo pot used aluminum carbonized silicon carbon brick, high aluminum brick. Bottom of the torpedo pot impact part uses nonburning aluminum carbonized silicon carbon brick, most of the rest using burnt stripping resistant high aluminum brick. Material for the aluminum carbonized silicon carbon brick comprises the alumina, electro-melting corundum, carbofrax, carbite, sintered corundum, aluminum, silicon, astringent, and so on, and the high aluminum brick comprises alumina, electro-melting corundum, carbofrax, silicon, silicon powder, bindeton and paper waste liquid. It is reasonable in formulation, mature in production process, with forming no need of high temperature baking with lower production cost. Using these two kinds of bricks, using durability of the overall torpedo can basically reach synchronic feature, application over 1700 times, with good effect and significant economical benefit.
