Description
Technical field the present invention relates to the electrode holde that the hot stove in ore deposit is used, and refers in particular to a kind of gentle ring type electrode holde.
The electrode holde that uses on the hot stove in the present various ore deposits of background technology adopts brasses to embrace ring type electrode holde structure more than 95% or combined electrode is controlled the device structure.
Brasses is embraced the ring type electrode holde and mainly is made of carrying cylinder, brasses, armful ring, protection screen, electrode and corresponding suspender member, insulating part, connector.
Its principal character is: this controls device is brasses to the conducting element of electrode, usually by the polylith brasses around one week of electrode, directly link to each other without any parts between two blocks of adjacent brasses; The brasses top has contact tube to link to each other with short net, and contact tube also is the turnover path of brasses cooling water simultaneously.Embrace and encircle the outside that is installed in brasses, the inboard cambered surface of brasses is pressed on the electrode, realize that electric energy is from the conduction of short net to electrode, for self-baking electrode, brasses also has another effect, cools off the electrode shell of contact site exactly, avoids the fusing too early of electrode shell steel plate or the distortion at this position.Brasses is embraced the ring type electrode holde can be applicable to various standard cylindrical electrodes.
The common trait of embracing ring provides the thrust of brasses to electrode, according to the mode difference that pressure is provided, be divided into nut type and embrace ring (seeing accompanying drawing 1, accompanying drawing 2), conical ring (seeing accompanying drawing 3, accompanying drawing 4), hydraulic pressure ring (seeing accompanying drawing 5, accompanying drawing 6), the hydraulic pressure ring is divided into bellows-type pressure rings and cylinder type pressure rings again by the difference of hydraulic unit.
The major defect of this structure is: (one) brasses is worked under hot environment, and the bottom is without any component protection, and most brasses are often scrapped because the bottom scaling loss is serious.(2) embrace ring and only exerted pressure in the brasses middle part, the most of contact-making surface of other of brasses is because the intensity of self just contacts with electrode, causes whole contact effect undesirable.(3) circularity of electrode shell is made the mismachining tolerance of sum of errors brasses intrados, and it is bad also to cause brasses to contact with electrode.(4) when electrode band voltage is put, require embracing ring has suitable thrust to brasses, should guarantee electrode relatively brasses slide, guarantee that again conduction is good between brasses and the electrode, do not beat arc, do not injure brasses but be difficult to assurance during actual pressing.Above reason causes the useful life of brasses not long, average about 1 year.Simultaneously, the rate of working continuously of the hot stove in whole ore deposit is not high yet, on average about 95%.
