摘要
A process for preparing molten- aluminium-plated steel sheets having good formability and high oxidation resistance at elevated temperatures comprises producing a steel containing 0.001-0.020% of C, 0.05-0.30% of Mn, 0.05-0.50% of Cr, 0.01-0.10% of Al, and 0.10-0.50% and not less than 10 times the C content of Ti, and making the steel into a hot coil with the coiling temperature not lower than 700 DEG C, cold-rolling said hot coil and plating the cold-rolled sheet by heating it to a temperature not lower than 850 DEG C using an in-line annealing type plating apparatus with non- oxidizing furnace.
