Abstract
1,139,201. Cleaning metals. DYNAMIT NOBEL A.G. May 11, 1966 [May 12, 1965], No.20993/66. Addition to 1,101, 273. Heading C7E. In a process as described in Specification 1,101,273 for removing scale from steel using an alkali metal hydride melt, the surface of the melt is covered with a saturated aliphatic hydrocarbon having a boiling point at least 20‹ C. higher than the temperature of the melt.
