الملخص

In this diploma there are four parts: (1) the general part deals with the projection of new blast furnace shop for production 132800 tons of pig iron per year. The new blast furnace shop will be provided by the iron ore from El Bahareya deposit, limestone from El Rifai deposited and coke from imported coking coals. Iron ore will be agglomerated to obtain self fluxing sinter. On base of raw materials the technology of sinter and pig iron production was worked out with application of respective calculation. To provide the needed quantity of pig iron, we projected blast furnace shop by two blast furnaces. After blast furnace profile calculation the useful volume was determined as 1033 m3. (2) The special part of diploma project deals with the consideration of additional fuel problems to decrease the coke consumption. There were theoretically considered the fundamentals of application gaseous, liquid, solid fuel and their mixtures. It was shown, that operation of blast furnace with additional fuels gases and liquid have been connected with increasing of gas volume and consequently with changing of productivity of the blast furnace. Published materials allowed summarizing the experience of natural gas injection in all aspects of blast furnace operation. To obtain the most efficient quantity of mazout injected, we investigated the technology of blast furnace (N. 1 and N. 2) operation with mazout injection, with the help of mathematical statistic method and production indexes during 1970 - 1973 years. It was established. That every 10 kg. Mazout save 13.5 kg. Of coke for blast furnace N. 1, but for blast furnace N. 2 There is no connection between the coke consumption and mazout consumption. The productivity is increased in blast furnace N - 1 by 15.2 % if we increase the mazout consumption from 57 kg / ton pig iron to 90 kg / ton pig iron as 1 suggested. We are theoretically studied the problems of increasing mazout consumption. it was shown the possibility of deposited carbon formation by injecting 90 kg . Mazout per ton pig iron. To provide the raising of mazout consumption we suggest new method for mazout injection without formation of deposited carbon. (3) The economical part considers the efficiency of mazout consumption on blast furnace N. 1. It was established that increasing of mazout consumption up to 90 kg / ton pig iron will give saving 0.85 L. E. per ton pig iron or about 119.600 L. E. in year. (4) The safety engineering part deals with the consideration of explosion under contact of metal with moisted parts like uncompleted drying ladles.
