摘要： PURPOSE:To give a satisfactorily large draft in an initial pass by coating the surface of a titanium sheet with oil containing a specified quantity of surface- treated fine grain calcium carbonate and cold-rolling the sheet as water, etc., is supplied. CONSTITUTION:When 20 - 70 wt% of surface-treated fine grain calcium is contained in oil with which a titanium sheet is coated, fine grain calcium carbonate exists between the titanium sheet and a projecting part of the ground surface of a work roll. Consequently, the titanium is prevented from a direct contact with steel and build-up is hard to be exerted. Further, in a continuous rolling, oil-contained fine grain calcium carbonate is heaped in ground traces of a work roll as if the ground traces are burried to very effectively prevent contact between metals. Consequently, the build-up of titanium on the work roll in the initial pass is prevented and since the calcium carbonate acts as solid lubricant, the increase of the friction coefficient in a roll bite is reduced drastically and a thin titanium article can be rolled productively.
