The application of aluminum silicate fiber products

Aluminum silicate fiber and ceramic fiber is a new type of lightweight refractory materials, the material has the advantage of light unit weight, high temperature resistance, good thermal stability, low thermal conductivity, low heat capacity, good resistance to mechanical vibration, small thermal expansion and thermal insulation performance is good, which wait for an advantage. Through special processing, it can be made into aluminum silicate fiber board, aluminum silicate fiber mat, aluminum silicate fiber rope, aluminum silicate fiber blanket, etc. New type sealing material has high temperature resistant low thermal conductivity, volume weight is light, long service life, tensile strength, good elasticity, non-toxic characteristics, is a new kind of material instead of asbestos, widely used in metallurgy, electric power, machinery, chemical heat insulation equipment.

Aluminum silicate fiber is a kind of high temperature resistant fiber. It has the advantage of light unit weight, high temperature resistance, good thermal stability, low thermal conductivity, mechanical shock resistance, elastic, sound insulation, electrical insulation and chemical stability is good, which wait for a characteristic. In metallurgical, chemical, electric power, machinery, industrial furnace such as high temperature insulation filling equipment used for high temperature furnace, kiln temperature preservation and other projects. It also can be used for high temperature sealing, filtering, noise elimination, catalyst carrier and reinforced composite materials. Aluminum silicate fiber products have board, blanket (mat), tube, rope, brick, etc. They used for high temperature furnace, kiln thermal insulation layer and filling production of fiber products.

The discussion on ladle slide gate plate and lower nozzle

During our visits to many steel companies around the world, we found that some of them focus too much on the service life of ladle slide gate plate and lower nozzle, some even ask for more than 10 heats, here are some of our opinions on this condition:

1.Longer service life slide gate plate and lower nozzle leads to more accidents. After being used for some time, leakages are tend to happen at the joints or molten steel could penetrate from the bodies. In addition to that, workers has different opinions on the using conditions of them, if a certain long life is fixed, accidents could easily happen;

2.Longer service life not necessarily mean less or easier work. Everyone knows Chinese steel industry is very mature, but the Chinese steel plants prefer one heat ladle slide gate plate or four heats at most, that’s because the sliding mechanism they choose is very easy to operate, it takes only less than 1 minutes to change the slide gate plates and lower nozzle, many of the long service life ladle slide gate plate and lower nozzle are with sliding mechanisms take 10 to 20 minutes to do that, which would affect the production procedure and increase workload;

3.Longer service life not necessarily equals to lower cost. The prices for long service life ladle slide gate plate and lower nozzles are normally very high, if something happens and the production has to be stopped, the ladle slide gate plate and lower nozzle can not be used again after cooling, which will be wasted.

Overall, we think it will be better if the customers choose ladle slide gate plate and lower nozzles according to their practical needs, not just based on which are with longer service life.
