The impact of electrode tip shape dynamics

Question 1

So wat was die issue wat hulle gesien het?

Answer 1

By n konstante weerstand stelpunt, pencil die elektrodes en begin dan inwerk, wat heatflux na die onderkant verhoog

Question 2

Wat is die hoof gevolgtrekking van hierdie studie?

Answer 2

Soos n elektrode pencil, verlaag sy effektiewe diameter, en dit veroorsaak n styging in the weerstand

Question 3

Anglo se smelter in Zimbabwe?

Answer 3

Unki, commissioned in 2018, circular, 12m met drie elektrodes

Question 4

Maximum electrode current volgend Barcza

Answer 4

I = 55D^1.5

Question 5

Hoof vergeltking wat hulle aflei in hierdie artikel?

Answer 5

Korreleer effektiewe weerstand met die pencilling
R-calc/R-ref = (D-ref/D-calc)^1.5

Question 6

So watse elektrode vorm verwag ons met brush arc?

Answer 6

Plat aan die onderkant

Question 7

Furnace secondary phase voltage =

Answer 7

transformer primary line voltage / tap ratio

Question 8

Furnace secondary phase voltage =

Answer 8

transformer primary line voltage / tap ratio

Question 9

Transformer secondary phase current =

Answer 9

(TX primary line current x Tap ratio)/sqrt3

Question 10

Electrode secondary current=

Answer 10

TX secondary phase current x sqrt3

Question 11

Electrode to bath voltage =

Answer 11

TX secondary phase voltage / sqrt3

Question 12

Electrode to bath voltage =

Answer 12

TX secondary phase voltage / sqrt3

Question 13

Electrode resistance =

Answer 13

Electrode bath voltage/electrode current

Question 14

Watse maatstaf stel hulle voor om electrode tip sharpening te meet?

Answer 14

Elastance = holder/resistance. As hierdie waarde oor tyd sak het jy n probleem. So logies in ons oonde is dit nie so maklik nie
