Since our factory implemented the principle of Chairman Mao Zedong on learning the theory of the proletariat’s dictatorship and anti-revisionism since 1975, we made great efforts to mobilize the masses to make technological innovations in 1978, revamp the hot stoves, raise the air temperature and stabilize the furnace condition On the basis of continuously improving the production level, 8,919 tons of pig iron were produced in 225 days in 1975, with an average daily output of 39.2 tons. The utilization factor was 3.007 and the average coke ratio was 0. 615 tons, which was in line with the historical best level Compared with the utilization factor of 29%, the coke ratio decreased by 223 kg / ton of iron, down 26.6%, the cost also dropped to 224 yuan / ton of iron, the utilization factor of three, coke ratio Fight oath. Among them, furnace reform is a major technological change
