Abstract
Compsn. for lining steel making ladles comprises used sand from previous linings mixed with 30 - 50% fresh "racecourse" sand. The used sand, not previously reused is cleaned of metallic incrustation lumps etc. and disintegration. The "racecourse" sand contains 84 - 92% SiO2 and 5 - 12% Al2O3 and consequently contains sufficient clay to bond the mixt. again.
