Abstract:

The development achievement of wear-resistant pre-fabricated block which has been used on CDQ chamber of Baosteel was introduced. The wear-resistant pre-fabricated block has the excellent performance of falling resistance, good thermal shock stability, high strength and wear resistance. The result of actual application at Baosteel showed that the conventional burnt mullite brick used at the same location of CDQ chamber was replaced by the wear-resistant pre-fabricated block, the wear rate of wear-resistant pre-fabricated block was reduced by 70% or more, the service life of refractory used at the cooling zone of CDQ chamber can be substantially increased, and the repair frequency and consumption of refractory can be reduced.
