Abstract
The utility model relates to an electrode for solar grade silicon. The electrode comprises an electrode body, wherein a convex electrode joint with an external thread is arranged at the front end of the electrode body; a concave electrode contact hole with an internal thread, which is adapted to the electrode joint, is arranged at the back end of the electrode body; and a cavity penetrating the electrode joint, the electrode body and the electrode contact hole is arranged at the center of the electrode body. Before the use of the electrode disclosed by the utility model, calcined petroleum coke or broken graphite is filled in the cavity at the center of the body in advance, the heat stress of the body can be relieved in the high-temperature using process, and the electrode body can be prevented from producing cracks.
Description
Technical field
The utility model relates to a kind of solar energy level silicon electrode.
Background technology
At present, metal smelting silicon is below the 1146mm with the general diameter of electrode, and be solid construction, the screw thread employing tooth form angle of electrode is 58 ° triangular-shaped electrodes screw thread, kind electrode is in the pyrolytic semlting use procedure, be prone to thermal stress body crackle and connecting portion crackle, even come off and cause quality accident.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can either intensifier electrode connects power, prevents loosening, dropout phenomenon, can prevent again the solar energy level silicon electrode of electrode body crackle.
The technical solution adopted in the utility model:
A kind of solar energy level silicon electrode, it comprises electrode body, described electrode body front end for protrude with externally threaded electrode nipple, described electrode body rear end be indent with the suitable electrode nipple hole with internal thread of described electrode nipple, the electrode body center is provided with the cavity that runs through described electrode nipple, electrode body and electrode nipple hole.
The diameter of described electrode body is 1020-1400mm.
Described electrode nipple and electrode body angulation β, electrode nipple hole and electrode body angulation γ are 120 °.
Described internal thread and externally threaded tooth form angle are 60 °, are circular arc at the bottom of the tooth, and its radius is 3-5mm.
The diameter of described cavity is 80-150mm.
Good effect of the present utility model is as follows:
Adopt the utility model, the contact resistance of contact site reduced when large specification electrode was connected, and prevented that electrode is rubescent at contact-making surface, avoided cracking;
After the utility model electrode thread connected, the arc-shaped structure of Bottom of Thread can relief of thermal stress, and it is loosening to prevent that electrode from high temperature producing, and had avoided the joint area crackle that therefore causes;
The utility model electrode before use, it is broken to fill in advance calcined petroleum coke or graphite in the cavity of body center, in the applied at elevated temperature process, can alleviate the thermal stress of body, avoids electrode body to crack.
