新余钢铁厂在改造旧式竖窑为“气烧”竖窑生产活性石灰取得投资省和效果大的基础上其技术进步方向有: 1.在轧钢加热炉上对煤气和助燃空气进行预热,降低加热炉能耗15％,气烧竖窑可节能7％,使加热炉和竖窑进入特等炉水平; 2.各种热工参数、计数仪表改为电子 Xinyu Iron and Steel Plant in the transformation of the old shaft kiln for the “gas burning” shaft kiln production of activated lime to obtain investment in the province and the effect of large on the basis of its technological progress are: 1. In the rolling furnace gas and combustion air preheating, reduce Heating furnace energy consumption 15%, gas-fired shaft kiln can save 7%, so that the furnace and shaft kiln into the special furnace level; 2. A variety of thermal parameters, counting instruments to electronic
