The schedule of existing coke plants and capacities is modified, incorporating into it the schedule of coke plants which are anticipated to close. The matallurical coke production capacities to 2000 are projected. The metallurgical coke capacity increases by 1.63 million tons, if the foundry coke producers make furnace coke. Coke shortages are expected to occur in 1993, 1994, 1998, and 1999, the projected peak steel consumption years. The equation is given in this paper. Using this equation and the expected population of plants, knowing their ages, coke supply curves are contructed for 1990 to 2000. The different strategies, which a steel firm could implement to minimize the adverse results of a metallurgical coke shortage, are assessed. The acceptable strategies are as follows; ranked from the most desirable to the least: develop and negotiate long term contracts for low cost foreign coke supplies; idle hot the coke capacity which is scheduled for closure; develop and implement supplemental powdered coal blast furnace injection technology; build new coke plants; and produce at maximum capacity and inventory coke for later use during shortages. The conservative and prudent approach for a steel firm, eliminating expected coke shortages, is to simultaneously implement the above three most desirable options.
