考虑到钢厂工艺变化对耐火材料单耗(公斤/吨钢)的影响,根据对1975年至2000年期间世界钢总产量的预测,推算出了此期间内世界钢厂对耐火材料的总需求量。分析表明,各地理区域在耐火材料消耗中所占的比重,将起显著变化。此外,虽然世界钢产量估计到2000年会达到14亿吨。但对耐火材料的总需求在1990年之前却将一直下降,仅当钢产量的增长造成对耐火材料需求的增长,能够抵消耐火材料单耗下降的效果时,总需求量才会再一次上升。
Taking into account the impact of technological changes in steel mills on the unit consumption of refractories (kg / tonne steel), based on the forecast of total world steel production from 1975 to 2000, the global demand for refractory materials by world mills was calculated the amount. The analysis shows that the proportion of refractory material consumption in each geographical area will change significantly. In addition, although world steel production is estimated to reach 1.4 billion tons by the year 2000. However, the total demand for refractory materials will continue to decline until 1990, and the total demand will not rise again until the increase of steel output causes the increase of demand for refractory materials, which can offset the decrease of unit consumption of refractory materials.
