炼铁工序提高煤比降焦节能探讨

Study on raising coal rate reducing the coke ratio and energy consumption in the iron making working procedure

提高煤比,降低焦比,对炼铁工序降低能耗起着关键作用。通过精料、提高风温和富氧率、优化喷吹工艺、抓好高炉操作等手段,可提高煤比,降低焦比和工序能耗。

Increase pulverized Coal rate and decrease coke ratio are the keys to reduce energy consumption in the iron making procedure. Pulverized coal rate was raised and coke ratio and energy consumption was reduced, by some meastures such as using refined mine powder, raising blast temperature and oxygen-enriched rate, optimizing injection technics, strengthening blast furnace operation.
