LC and ULC castables

      Sheng Iron currently uses amorphous refractory materials to replace shaped products in heating furnaces. The LN, JR and DGG series products have been the first choice by design institutes and customers for working lining of heating furnaces. DDG series are for water-cooling pipes lining. Characterized by good thermal shock resistance and spalling resistance, they have been applied in more than a hundred heating furnaces domestically,and well received by customers.
