Increasing engineering output raises the demand for foundry production at a time when the trend is towards weakly- and non-caking coal inclusion in charges for cokemaking. Tests were continued with the ring furnace, with excess pressure in the roof area, and temperatures in this zone ranging from 750-960 C. The coke briquettes had appreciable volatile matter due to the lower temperatures and retained their surface roughness. Further tests were carried out in which the briquettes were overlain by highly caking smalls which filled the interstices, resulting in improved briquette surface and general properties. In the cupola itself, the coke briquettes appear to have behaved satisfactorily, retaining shape during descent right through to the end of the heating period. Equal amounts of briquetted and conventional coke combined to raise cupola output and raised the iron tap temperature by 60 C. The strength and density of the briquettes expands the combustion zone and up-grades the product.
