Description

The electrode holde that is used for the hot stove in ore deposit

Technical field

The utility model relates to a kind of electrode holde that is used for the hot stove in ore deposit.

Technical background

At present, the electrode holde that is used for the hot stove in ore deposit is because of the design defectiveness, and it is many to cause that the brasses loss often takes place, big cover, little cover are played the heating of arc leakage power and water ring gland and are beaten faults such as arc, repair rate height, time are long, have a strong impact on ferroalloy output, in addition cause as accidents such as electrode, electrical equipment.The brasses loss is many, and removing is because brasses adopts casting system technology, the contacting outside the factor such as not enough designing requirement of its difficult quality guarantee and every block of brasses and electrode, and another key factor is that the contact pressure between brasses and the electrode is inhomogeneous.Big cover damage too much mainly be because: carry away under the too high situation of charge level at electrode, the following welding tip of brasses gives out a large amount of heat and is covered by big cover, at this moment the about 40-60 of water temperature ℃ very easily forms incrustation scale in the big cover, if this situation often occurs, then make big cover occur being heated inequality and ftracture and leak.In like manner, too high when charge level, when the thorn fire turns over quarrel, cause big cover cracking to leak.Little cover damage too much also be because: when electrode carries away under the too high situation of charge level, the following welding tip of brasses gives out a large amount of heat, when big cover covers, not only big cover the heat absorption also basic and big cover of little cover simultaneously is in same environment, circulating water temperature is in about 40-60 ℃ in the little cover, extremely easily form incrustation scale,, then make little cover occur being heated inequality and ftracture and leak if this situation often occurs.And because little cover directly contacts with brasses,, cause brasses and little inner room to beat arc, cause little cover to leak if brasses is irregular or electrode deformation can make little cover not enough to the pressure of brasses.Also may because of overlap greatly and bell between destroyed electric leakage of insulating barrier, cause big cover, little cover to beat arc and leak.
