Inner lining structure for torpedo pot and aluminium carbonize silicon carbide brick and high aluminium brick used for torpedo pot

Abstract

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.

Description

1. Technical field: [0001] The invention belongs to the field of refractory materials, in particular to an inner lining structure of a torpedo tank, an aluminum silicon carbide carbon brick and a high alumina brick for the torpedo tank. 2. Background technology: [0002] At present, most of the refractory bricks used in the lining working layer of torpedo tanks are made of aluminum silicon carbide carbon bricks (that is, Al 2 o 3 -SiC-C bricks, referred to as ASC bricks), this brick has the following main disadvantages: poor oxidation resistance, easy to oxidize and fail during use, resulting in fast erosion of slag lines and scoured parts, serious sticky slag, and difficult maintenance; low-grade bricks have low service life, And the high-grade Al required for life ≥ 1000 times 2 o 3 - SiC-C bricks are expensive and costly. The authorized application number 01126576.0 discloses a fired aluminum-carbon brick for mixed-iron vehicles, which is used in the working layer of ...

[0002] At present, most of the refractory bricks used in the lining working layer of torpedo tanks are made of aluminum silicon carbide carbon bricks (that is, Al 2 o 3 -SiC-C bricks, referred to as ASC bricks), this brick has the following main disadvantages: poor oxidation resistance, easy to oxidize and fail during use, resulting in fast erosion of slag lines and scoured parts, serious sticky slag, and difficult maintenance; low-grade bricks have low service life, And the high-grade Al required for life ≥ 1000 times 2 o 3 - SiC-C bricks are expensive and costly

The patent with the authorized application number 01126576.0 discloses a fired aluminum-carbon brick for mixed-iron vehicles, which is used in the working layer of some mixed-iron vehicles. The disadvantage of this aluminum-carbon brick is that it has poor corrosion resistance to molten iron and slag, Long service life of line area and high operating cost
