Abstract

PURPOSE: To effectively carry out the raw material throwing control of blast furnace inlet part, by utilizing charging locus assumed by a new calculation theoretical formula, at the bell type raw material charging apparatus of blast furnace.
CONSTITUTION: Construction of bell type throwing machine is determined by falling locus of charging raw material based on the usual formula I at the bell type raw material throwing apparatus of blast furnace. On this occasion, actual falling locus is shifted from assumed falling locus to the side of furnace center and it is not good for blast furnace operation. Throwing of charging material is controlled by a new theoretical formula II by revising the formula I. By the above formula II, the falling locus assumed by the formula II, is accorded with the actual falling locus, because the distance l between the contact point of the large bell 1 and the bell cup 2 being difficult to assume by the usual formula I and the tip end of the bell 1, is accurately found by considering the velocity of raw material immediately after opening the bell 1 and that of at opening time of the bell 1.
