- W4285536556 abstract "The objective of the article is to perform an analytical investigation of ore loads distribution upon coke along the radius of the furnace top, equipped with a bell-type charging device at charging by the systems with uneven coke distribution in skips. Mathematical simulation of the arrangement of sintered ore and coke layers at direct charging and charging with «coke ahead» when the charge was placed on the horizontal surface and the ridge of the materials was placed near the top walls and coke mass in the skips was varied .It was found that at varying the degree of filling of coke supply skips (CSSC↓) from 35 to 80% the interval of ore ridge displacement exceeded 10% of the top radius, while the value of relative ore load at the walls exceeded 20%. Redistribution of ore loads along the radius of the top at charging with cycles consisting of direct supplies and supplies of «coke ahead» type at varying coke mass in supply skips CSSC↓ were analyzed. The maximum length of the ore material along the radius of the furnace top at charging in cycles with equal degree of coke skips filling at «coke ahead» charging is not altered. An increase in ore load in the charge and reduction in ore stock promoted the growth of the interval of varying the degree of coke skips filling. A modified impulse mode of the furnace charging, consisting of the cycle direct supplies and supplies of «coke ahead» type promotes creation of gas-permeability axial funnel and improves utilization of reducing potential gas. Also analyzed was an opportunity of regulating the radial distribution of ore loads by application of the method of uneven coke skips filling for the charging systems with formation of high coke and ore layers" @default.
