Dec 07 2018 · In recent years quick dry Al-SiC-C castable is developed for casting houses which only have one iron running trough. The development of self flow Al-Si-C castable brings lots of convenience for casting construction. The unit refractory consumption of per ton iron is significantly decreased with the improvement of castable quality.
