一、前言新、老三轧的生产能力,要求其前工序的炼钢厂供应600万吨粗钢。炼铁厂向炼钢厂供应多少铁水,要由炼钢吃多少废钢来决定。武钢唯一的鄂东铁矿山基地,每年只能供应200万吨左右的生铁所需铁矿石。炼铁厂四座高炉容积是:1386米~2、1551(1436)米~3、1513米~3、2516米~3。炉缸直径是8.2米、8.9米(8.4米)、8.6米、10.8米。1~3#高炉配置K—4250型离心式鼓风机。由于鼓风机叶片的磨损,容积效率的降低,进热风炉前所测得的实际最高风量为2700~2800标米~3/分。4#高炉配置VA9018(A)型轴流式鼓风机,风量5600标米~3/分。因上料和炉顶装置等系统的设备不配套,鼓
I. INTRODUCTION The production capacities of the new and the third rolling companies require the 6 million tons of crude steel supplied by the steel mills of the previous process. The amount of hot metal that the ironworks supply to the steelworks depends on how much scrap it consumes. The only iron ore base in Hubei Province of Hubei Province that can only supply about 2 million tons of pig iron per year. The four blast furnace capacity of the ironworks is: 1386 m ~ 2,1551 (1436) m ~ 3,1513 m ~ 3,2516 m ~ 3. The hearth diameter is 8.2 meters, 8.9 meters (8.4 meters), 8.6 meters, 10.8 meters. 1 ~ 3 # blast furnace configuration K-4250 Centrifugal blower. Due to the wear and tear of the blower blades, the volumetric efficiency is reduced, and the actual maximum air flow measured before entering the hot blast stove is 2700-2800 m 3 / min. 4 # blast furnace configuration VA9018 (A) -type axial blower, air volume of 5600 standard meters ~ 3 / min. Due to feeding and roof equipment and other system equipment is not complete, drum
