PROCESS FOR MAKING STRONG METALLURGICAL COKE ABSTRACT OF THE DISCLOSURE The strength and density of a metallurgical coke produced in a slot coke oven are both increased by replacing at least a part of the normal loose charge in the oven with compacted materials and fragments thereof made from a mix- ture of particularly sized particulate fusible bituminous coal particles, non-fusible particles of a material compatible with the burden of a blast furnace, and water. During compact- ing the pressure and the moisture content of the mix are such that at least some water is squeezed out of the mix. The non-fusible materials that are useful include non-coking coals, poorly coking coals, other carbonaceous materials, such as coke breeze, char, anthracite, lignite, and iron oxide-bearing materials, such as iron ores and waste materials from steel plants. At least a major proportion of the fusible particles and at least a substantial proportion of the non-fusible particles are smaller than about 0.15 mm. The proportion of fusible to non-fusible particles used is such that such mixture of compacted materials and fragments made from such compacted materials that is charged to the slot coke oven becomes transiently plastic, shrinks and forms a single mass of coke when heated to a coking temperature in the oven, which coke mass is readily dischargeable from such oven.
