At present, the lining of the refining electric furnace is made of knotted magnesium ramming material, which is often used to produce medium and low carbon ferromanganese or medium and low carbon ferrochrome. The service life (furnace age) of the medium and low carbon ferromanganese lining is generally about 400 furnaces. If it encounters peak … Read more
Since carbon-free ladle bricks do not contain carbon, their thermal conductivity is lower than that of carbon-containing ladle bricks. It can reduce heat loss during the use of the ladle and the thermal impact on the cladding. According to the statistical results of the shell temperature (cladding wall part) of the carbon-free ladle brick test … Read more
