Description
Technical field
The present invention relates to a kind of novel holding type electrode shell structure and its installation butt-joint process, belong to electrode shell manufacturing technology
Field.
Background technique
At present the country mineral hot furnace use the main partial pressure ring type of electrode shell and two kinds of composite electrode holder formula；It is had by oneself not because each
Substitutive advantage, while haveing the shortcomings that again inevitable, especially more disadvantages may be present in conventional combination holding type electrode: 1,
Arc plate component is in molding, due to steel plate internal stress problem, profiled sheeting and design requirement village gross error.
2, production process is many and diverse, and production automation program is difficult to improve.
The production of country's composite electrode holder formula electrode shell uses unified production model substantially at present, and part is more, and process is more,
And assembling process is difficult to realize efficient automated production.
3, making material requires stringent, increased costs.
Since conventional combination holder formula electrode shell production technology determines that its material must be unified using size, specification
Cold-reduced sheet, surface requirements are higher than the production requirement of pressure rings electrode shell, must not have the defects of corrosion, spot, to avoid in resistance
Lack of penetration situation is caused when welding.
3, electrode shell production quality is unstable, it is difficult to guarantee.
Composite electrode holder formula electrode shell shell is formed by multiple groups arc plate and inner reinforced plate seam weld, weldquality by pressure, electric current,
The many factors shadows such as speed of welding, cooling velocity, welding machine electric power quality, material surface quality, the Forming Quality of gusset and arc plate
It rings, thus is difficult to ensure seam weld quality, need to carry out electrode shell quality testing.
4, resistance welder, the feelings being irregularly lost in the work of internal high-temperature systems and conductive copper pinch roller for a long time due to its system
Under condition, it is difficult to guarantee thermofussion welding quality
4, welding quality inspection is difficult, and time-consuming.
Composite electrode holder formula electrode shell detects common method and has at present:
1, it makes an arc light leakage method.This method is simple and fast, but poor accuracy, and people is needed with the naked eye to judge, detection leakage phenomenon easily occurs, and
It is difficult to find tiny defect.
2, kerosene osmosis.The method can effectively detect tiny welding defect, but take a long time, and be not suitable with batch detection,
Reexamining, time-consuming, increases work load.
Therefore, conventional combination holder formula electrode shell quality is asked because of the plant issue of electric resistance welding and the uncertainties such as artificial etc.
Topic, it is difficult to meet the production needs of mine heat, and will affect electrode shell quality.
There is also following shortcomings for composite electrode holder formula electrode shell:
3, seam weld surface quality is poor, and conductive contact element loss is big: due to seam weld using base material compression pass to high current into
Row welds rear surface and has rough groove together from fusion welding.After the completion of seam weld, beaten although manually carrying out weld seam
Mill, but still there are problems that degree of polishing flat, when gap is excessive, and spark phenomenon is generated, influences to produce, and exacerbate conduction
The abrasion of element.
4, the outer muscle of conduction of single-unit electrode shell is because welding quality is difficult to control and is detected and electrode shell docks spreading difficulty
Greatly, quality is difficult to control, and leakage paste easily occurs, pierces fiery phenomenon.
5, when docking, the upper and lower electrode shell that saves docks using artificial docking and lacks standard, on the electrode shell after docking similarly hereinafter
The heart all, perpendicularity difference, influence conducting element service life and effect, cause centainly to bear to production.
6, conventional combination holder formula electrode shell, due to reasons in structure, need to carry out outer gusset docking site in spreading
It is fully welded, and the position narrow space, complications, welding difficulty are big, therefore higher to operating personnel's technical requirements, existing polishing in addition
Tool is not achieved polishing and requires, and also results in many difficulties to the perverse polishing of subsequent muscle, is that polishing point up to standard all can be to conductive copper member
In at serious damage, blowing out maintenance efficiency is high, increases enterprise operation expense.
