Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a hot-rolling mill lubricant enabling to cut rolling cost by effectively lower rolling force when steel materials are heated and rolled in a range of 200-1,200°C, and provide a steel hot-rolling method using this lubricant. SOLUTION: This hot-rolling mill lubricant comprises a base oil and at least one kind of polymer selected from the group consisting of an isobutylene homopolymer and isobutylene copolymer with a number-average molecular weight in the range of 8,000-100,000. This steel hot-rolling method includes feeding the hot-rolling mill lubricant for steel by a water-injection system. COPYRIGHT: (C)2008,JPO&INPIT
