PURPOSE:To obtain a product of high quality stably and highly efficiently, by using an emulsion containing >=1/2 of its oil content consisting of the prescribed particle size, in rolling a material. CONSTITUTION:An emulsion is prepared, in which >=50% of the oil content is formed into oil particles having 6-15mu average particle size. The emulsion is used as a rolling lubricant in rolling steel plates. In this way, the rolling is operated stably, and a high quality product is manufactured highly efficiently. |
