Abstract
A liquid-phase rolling technique for preparing composite metal (bimetal or trimetal) includes such steps as respectively smelting the needed metals, pouring into a vertical two-roller mill with cooling device and three or four baffles for rolling bimetal or trimetal, rolling, forced cooling and annealing. Its advantages are preventing metal interface from oxidization, and fine and firm texture on bonded interface.
