- Abstract
The paper deals with the problems of homogeneity of flux-cored strip charge at its mixing in double-cone mixers. Optimum mixing time for mixers of different volume was determined experimentally. Equipment for manufacturing flux-cored strips was optimized and a new design of withdrawal-roll set using pressure sensors was developed, that allows determination and adjustment of press-down force of withdrawal rolls of the mill. The paper gives the results of studying the influence of the degree of charge compaction on welding-technological properties of flux-cored strips. It is found that increase degree of compaction leads to a noticeable increase of the coefficient of electrode material melting. Insufficient or excessive degree of compaction adversely affects the welding-technological properties of flux-cored strips-spattering is increased and process stability deteriorates.
