在厂党委的正确领导下,在市科技组及江苏师范学院数学系革命师生的指导下,我厂组织三结合试验小组,应用正交试验设计的科学试验方法,在一号高炉上探索合适的装料制度,以提高煤气利用,降低焦比,提高产量,为社会主义革命和建设事业多作贡献。我厂一号高炉自一九七四年七月三日——二十六日选择了料线(1100m/m,1200m/m,1300m/m)、矿批(1400Kg,1600Kg,1800Kg)、装料次序(疏抑结合,普遍大,花装),按三因素,三水平正交试验设计正交表[2],进行了九次试验。通过试验,该高炉在现有的原料、设备条件与喷吹水平的基础上,在所试验的范围内,找到了最佳水平组 Under the correct leadership of the factory party committee, under the guidance of the city science and technology group and the revolutionary teachers and students of Department of Mathematics, Jiangsu Teachers College, I plant a combination of three test groups, the use of orthogonal experimental design of scientific test methods, to explore the appropriate blast furnace Of the loading system to improve gas utilization, reduce coke ratio, increase production, make more contributions to the cause of socialist revolution and construction. The blast furnace of No. 1 of our factory has chosen the material line (1100m / m, 1200m / m, 1300m / m), ore batch (1400Kg, 1600Kg, 1800Kg) from July 3 to July 26, According to three factors and three orthogonal test design orthogonal table [2], conducted nine tests. Through the test, the blast furnace in the existing raw materials, equipment conditions and the level of injection on the basis of the range of tests to find the best level group
