METHOD FOR DETERMINATION OF TIME OF FUSION MATERIAL LOADING IN ARC FURNACE, DATA PROCESSING DEVICE, MACHINE-READABLE PROGRAMME CODE, STORED DATA CARRIER AND ARC FURNACE Russian patent published in 2014 - IPC F27B3/28 C21C5/52 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, particularly, to loading of fusion material, in particular scrap (9) into arc furnace (1). Note here that arc furnace (1) has at least one electrode (3a, 3b, 3c) for heating of fusion material (G) by electric arc in arc furnace (1). First signal (S) is defined for determination of electric arc base state on the side of fusion material proceeding from registered electrode current (I_k). Note here that defined is if said first signal (S) exceeds the preset threshold magnitude for preset minimum time duration. Note also the time moment of loading is reached at the earliest when said first signal exceeds threshold magnitude for preset minimum time duration to define moment of loading oriented to arc base state for functioning of arc furnace.

EFFECT: lower power and material input, accelerated process cycle.
