Abstract

The utility model relates to an alumina-silicon-carbide-carbon-brick for a fish torpedo hot metal mixer car, which is of a rectangle with angle; the length a is 310 to 320mm, and the height b is 300 to 310mm, and the left width c is 92 to 97mm, and the right width d is 82 to 87mm, and the distance e from the bottom edge to the corner point is 100 to 107mm, and the angle alpha is 160 to 175 degrees. The utility model overcomes the problem that a surplus brick seam exists when the arc conical part of the torpedo tank is built by two bricks; the original two wide jade bricks for the radian measure of the torpedo tank are changed to be one vertical jade sectional brick with an angle, so that the service life is improved from 878 times to 1100 times, and the service life is improved by 20 percent.

Description

Fish torpedo type iron mixing vehicle aluminum oxide-silicon carbide--carbon brick

Technical field

The utility model belongs to a kind of refractory material, is specifically related to a kind of fish torpedo type iron mixing vehicle aluminum oxide-silicon carbide--carbon brick.

Background technology

The torpedo type hot-metal bottle is splendid attire and the equipment that transports molten iron, its major function is not only and directly is transported to pneumatic steelmaking with blast-melted, most as External refining vessel in the modern times smelting, promptly in the torpedo jar, molten iron is carried out desulfurization, dephosphorization and desiliconization, provide desirable molten iron for smelting clean steel.In the long-term process of using of torpedo jar; the torpedo tank liner refractory material can be subjected to strong thermal shock; the chemical erosion of slag; molten iron is under the stirring of air-flow when " three take off "; the torpedo tank liner refractory material caused wash away, wear and tear, the strong thermal shock effect regular meeting of variation of temperature and use in the torpedo jar makes that peeling off appears in the ladle lining refractory material, melting loss and the cracking of goods and floating of brick.Torpedo jar radian shape face is originally by two brick building at torpedo jar radian shape conical ring position of wide hard fine jade shape, build many brickwork joints by laying bricks or stones, service life and torpedo jar other can not be synchronous, molten iron caused the erosion of brick service life can not be synchronous easily below brickwork joint corrodes when its reason was to use the life-span to acquire a certain degree, and general steel mill uses and promptly can not use for 878 times again.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of fish torpedo type iron mixing vehicle aluminum oxide-silicon carbide--carbon brick, overcome torpedo jar radian shape conical ring position by two brick problems of building many brickwork joints, brick by a band angle replaces two original bricks, can make improve 20% its service life.

The technical solution of the utility model: a kind of fish torpedo type iron mixing vehicle aluminum oxide-silicon carbide--carbon brick, it is shaped as the rectangle of band angle, length a is 310～320mm, height b is 300～310mm, left side width c is 92～97mm, right width d is 82～87mm, and the base is 100～107mm to the angle flex point apart from e, and angle [alpha] is 160 °～175 °.

The utility model compared with prior art has following beneficial effect: at first improve from material, select for use aluminium oxide, carborundum and carbon synthetic; Next torpedo jar radian shape is changed into the perpendicular fine jade special shaped brick of a band angle by two original wide perpendicular fine jade shape bricks with brick, before not changing, two brick building at torpedo jar radian shape conical ring position, build many brickwork joints by laying bricks or stones, service life and other position of torpedo jar can not be synchronous, access times were brought up to 1100 times now at 878 times in the past, improved service life 20%.
