selection of refractory materials for various parts of blast

Refractory Materials: April 2015

Refractory materials must be strong at high temperatures, resistant to thermal shock, chemically inert, and have low thermal conductivities and coefficients of expansion. Refractories are more heat resistant than metals and are required for heating applications above1000F(538C).

Refractory and insulating materials

1982/1/1The selection of refractory brick for a specific application has much in common with the selection of a man for a job. The first task is to write a job specification, the second to interview the candidates, and the third to choose the 'best-buy', not on some specific qualification but on a hunch based on all the information available.

Refractory Materials: October 2015

However, refractory selection also depends on the operating conditions, while the operating conditions depend on the position. According to the temperature, checkers can be divided into four zones: Top zone (from the first row to 1,350℃), Mid zone (from 1,350℃ to 1,000℃), Condensation zone (from 1,000℃ to 700℃) and Lower zone (from 700℃ to rider arches).
