In the past decade continuous casting of steel into billets and slabs without going through the ingot stage has drawn widespread attention in the steel industry. Mold lubrication is vital to continuous casting to prevent sticking. Approximately 50% of this operation uses a vegetable oil lubricant, primarily rapeseed oil. Trimethylolethane, trimethylolpropane, trimethylolbutane and pentaerythritol esters of partially hydrogenated soybean fatty acids, derived from commercially hydrogenated soybean oils, have been readily prepared in good yields. Preliminary measurements of viscosities, smoke, flash and fire points of these polyol esters indicate that they are possible candidates for use as lubricants in the continuous casting of steel.
