材料是汽车制造的基础和保证。在各种汽车材料中,钢铁材料是汽车制造用量最大的材料,尽管随着相关材料的发展,钢铁材料的替代材料比例逐渐增大,钢铁材料的单位用量呈下降趋势;但是预计在以后相当长的时间里,金属材料仍将处于主导地位。就目前的汽车生产制造来看,钢铁材料约占汽车制造所用材料的70%以上。据统计,2009年汽车用钢(板管)产量为1443.6万吨;2010年汽车用钢(板管)产量为1847.7万吨;2011年汽车用钢(板管)产量为1750万吨。由此可见,钢铁产业的发展对汽车行业的影响和支撑是显而易见的。
Material is the foundation and guarantee of automobile manufacturing. Among various automobile materials, steel materials are the most used materials for automobile manufacturing. Although the proportion of alternative materials for steel materials gradually increases with the development of related materials, the unit consumption of steel materials tends to decrease, but it is expected to be considerably longer Of the time, the metal material will still be in the dominant position. In terms of current automobile manufacturing, steel materials account for about 70% of the materials used in automobile manufacturing. According to the statistics, the output of automobile steel (plate and tube) was 14.436 million tons in 2009; the output of automotive steel (plate and tube) was 18.47 million tons in 2010; and the output of automotive steel (plate and tube) in 2011 was 17.5 million tons. Thus it can be seen that the impact and support of the steel industry on the automotive industry is obvious.
