METHOD FOR NUT COKE SEGMENT CHARGING FOR IMPROVING GAS FLOW IN BELL-LESS BLAST FURNACE

摘要

The invention of the blast furnace coal injection in Veles year, raw material feeding mode junggoe coke charging method relates to, water charged to the furnace in case of measuring probe according to the basis weight of junggoe separate temperature significantly drooping portion of the coke on the result of poor ventilation automatically on those portions of the junggoe coke charged to a method for improving the permeability to ; The present invention provides a method of Veles junggoe coke blast furnace charge, furnace charging water probe measurements with the results of analysis of the measured data center breathable bad part, middle part, three-part divided by the charge control command notch wall Step out with; The contents of the selection command from the notch control program step 29 in the process computer 20 sends a sialic T 20-1 and to show whether the signature whether the cement charged junggoe coke charged to the mixing operation by self-determination step of the; Special moments junggoe coke charge for basis weight value inputting the input and junggoe exposed coke charging order; And transmitting the control signal and the basis weight of the basis weight junggoe coke complete detection signal to the links when exposed PLL 23 and the PLL when the raw material (24) to control the basis weight junggoe coke discharged from the raw material during PLL (24); Once in control from the raw material during Piel steps to imports of coke charging order junggoe input (25) occupies one coke charged by the input matrix is complete, exposed to import coke junggoe exposed hopper (13) during Piel (23) provides chapter of coke junggoe cubic method for improving the permeability of a bell-less blast furnace comprising the step of transmitting the substitute jangipryang junggoe coke import signal that can be discharged to the junggoe coke (24).
