摘要：
A hot-rolled coil having excellent adaptability for pickling can be produced by applying to the sides of the hot-rolled coil, a compound of an alkaline metal or alkaline earth metal, or an oxygen compound of boron, germanium, tin, antimony, lead, bismuth or vanadium. One or more of the aforesaid compositions when applied to a hot-rolled coil serves to suppress the formation of oxide film on the surface of the coil and/or promotes the solubility of the oxide film in the pickling tanks to the extent such oxide film does form.
