摘要： The method of producing blast furnace coke by (1) compacting a finely divided coal wherein at least about 60% by weight of the coal has a diameter of less than about 1/8 inch to form a coal compact, which compact immediately after removal from the compacting means comprises at least about 20% by weight of particles having a particle size of less than 1/4 inch in diameter; (2) breaking the thus formed compact such that the bulk density is sufficiently increased to be capable of conversion into coke suitable for use in large blast furnaces upon carbonization thereof; and (3) carbonizing the broken compact to thereby produce blast furnace coke having a minimum hardness of about 68 and a minimum stability of about 55. The compacting is preferably performed at a pressure equivalent to that achieved by passing the finely divided coal between rolls at a pressure applied to the coal of between about 20 and about 60 tons per lineal inch. Also preferably in the breaking step at least about 95% of the compacted coal is reduced to particle sizes ranging from about one inch to less than about 100 mesh.The invention also includes a system comprising a coal blender, a coal compactor, apparatus for breaking the formed coal compact, and a coking oven and apparatus for charging the broken compact into the oven.

摘要： Method and apparatus are described for the controlled cooling of processed oxidic ores in a shaft furnace in order to produce an improved product. Means are provided in the cooling section of the furnace chamber that enable the chamber to be divided into separate regions within each of which the admission of low temperature reducing gas can be regulated in order to more effectively control the distribution of reducing gas across the furnace.
