Nijhawan, B R (1959) Iron and Steel Industry in India. In: Symposium on Iron & Steel Industry in India Organised by the NML, Aug.'1959, NML, Jamshedpur.
In this short review, it, is not proposed to discuss the production of iron and steel in ancient India-- the subject has been Well covered in many excellent papers such as by Mr. S. K. Nanavati in his Presid- ential address before the Annual General Meeting of the Indian Institute of Metals (1958). In different hills and jungles, the Adibas,is are still extract- ing iron in a very crude form. However, with the establishmentof iron and steel industry along modern lines,the decline of such village industry has been very rapid. The general pattern of iron and steel industry in India has undergone considerable changes under the planning and development that have taken place during the Second Five year Plan. By the comp- letion of the Second Five Year Plan, the ingot steel capacity is expected to increase to six million tons per annum and this is likely to be stepped up to six- teen million tons per anumn by the end of the Third Five Year Plan. It is well known that India posse- sses immense reserves of high grade iron ores (more than twenty thousand million tons. Although India possesses huge reserves of coal estimated at about forty thousand million tons down to a depth of two thousand feet, only a small fraction of it -hardly about fifteen hundred million tons can be classed as good metallurgical coal from which coke for blast furnace high grade can be produced. A concentrated drive for the conservation of metallurgical coal is therefore all imperious necessity. The use of good coking coals in railway locomotives, steam-raising boilers, etc.,is wasteful and must he urgently checked. New locomotives are therefore being designed to operate on lower grades of coals. Electrification of the rail- ways is being contemplated which should further reduce the demand for metallurgical coal. It is expected that as a result of changes in the design of locomotive boilers, the railways which use about 4.7 million tons of coking coal annually, will use progressively more non-coking coals releasing large tonnages of coking coal for metallurgical use. The recent policy of export of high grade metallurgical coal has also to be rationally examined.
