Abstract :
D. M. Petty: In reading the introduction to this paper, I noted that there was just one rather important point which Mr. Umansky did not cover. I think it is a rather vital point and is becoming more vital every day. That is, the relation of the power generated in steel plants to that which is purchased. A number of steel plants are making it a point to buy a certain proportion of their power and with the advent of interconnections of large power companies, I think the interchanging of power between steel companies and power companies becomes increasingly important. The power companies themselves, naturally, having a wider range of load, are now able to absorb waste-gas and waste-heat energy better than they otherwise could have done had their system been limited to a small territory, it being understood, of course, that the steel plant has this power available as a by-product.
