High-alumina mortar from scrap of refractory articles after use in metallurgical units

Scrap of refractory articles of grades MKS-72, MLKh-65, and ShKh-42 after use in steel-teeming and intermediate ladles of the OMK is studied. The possibility of using after-use scrap in the production of mortar is investigated. Experimental batches of high-alumina mortar have been produced and tested with positive results in linings of steel-teeming and intermediate ladles.
