我国自６０年代初开始生产热镀锡板，但迄今还没有建立起具有一定规模的生产基地，也没有形成完整的生产系统，生产技术还处在相当低的水平上，与国外一些钢铁工业较发达国家相比差距很大。例如，国外镀锡板产量占粗钢产量的比例约为１．５％～５．５％，我国目前仅为０．２％ China started to produce hot tinplates since the early 1960s, but so far it has not established a production base with a certain scale, nor has it formed a complete production system. Production technology is still at a relatively low level, compared with some foreign iron and steel industries. The gap between developed countries is very large. For example, the proportion of foreign tinplate production to crude steel production is approximately 1.5% to 5.5%, while China’s current production is only 0.2%.
