A new series of V-TPV rectifiers is intended for food by a direct current of arc electric furnaces of smelting of various brands staly and alloys, chugun, non-ferrous metals (aluminum, copper, nickel), including rectifiers can be used at reconstruction of arc furnaces of alternating current with their transfer to more perspective furnaces of a direct current.
EFFECT OF INTRODUCTION
Use of rectifiers in arc electric furnaces of a direct current in comparison with arc electric furnaces of alternating current allows to lower:
expense of the graphitized electrodes in 2÷5 of time depending on a shikhtopodgotovka;
· an electric power expense on 5÷7 of %;
· a consumption of fire-resistant materials on 20÷30 of %;
· an expense of initial raw materials on 1,5÷2 of %;
· metal waste on 4÷5 of %;
· an expense of the alloying additives on 20÷30%;
· noise level is up to 85 dB;
· quantity of pylegazovybros in 8÷10 of time;
· a flicker effect in 2÷4 of time.
