'a machine for rolling, grooving and spiking for compacting of stamped coal cake inside the hot coke oven for improving the quality of coke'.

摘要

This invention relates to a machine for rolling, grooving and spiking for further compaction of charged stamped coal cakes for improving quality of coke comprising a beam connected with atleast one compacting roller at its front end by means of shaft wherein the beam and roller are driven by suitable means. It is associated with the following advantageous features:- - Further compaction of the stamped coal cake inside the hot coke oven further increases its bulk density and makes the resultant coke more stronger with higher CSR valves and lower CRI. - Further compaction of the stamped coal cakes inside the hot coke oven eliminates the gaps between the charged coal cakes and oven walls thereby permitting utilization of the beneficial effect of the coking pressure developed during carbonization of the coking blends, which significantly improves the quality of the coke produced. - Increase in the productivity of the oven as wasteful gaps are eliminated from the coking chamber. - More uniform quality of coke. - Use of more quantity of cheaper and lower grade coals in coking blends to produce good quality coke, which makes production of metallurgical coke more cost effective.
