The refractory linings of cold blast cupolas have a short life of less than 24 hours so cupolas are operated in pairs each used alternately while the other is re-lined. In hot blast cupolas the exhaust gases are used to preheat the blast to ºC reducing coke consumption and increasing the iron temperature to more than 1500ºC.

Monolithic Refractory. These boiler refractory materials are unshaped and have become the most preferred option in the refractories industry over the last two decades. This is mainly due to economic considerations their rapid installation time lower cost of raw materials and less manpower needed for refractory installation.

Continuous casting of steel billetsIspatGuru

Mar 19 2016 · In some plants the tundish is preheated to drive out the volatile constituents in the certain type of the linings which may contribute hydrogen to the steel and also for the better control of the steel temperature. A major problem with tundish operation is the clogging of the pouring nozzles by solid inclusions such as alumina (Al2O3).
