A graphite electrode joint and electrode group pair device

Abstract

The invention discloses a graphite electrode joint, which comprises a joint main body. The joint main body comprises a middle cylinder and a conical connecting body coaxially arranged on both sides thereof. The outer peripheral surfaces of the connecting bodies on both sides are provided with threads. The connecting body is threaded with the corresponding graphite electrode, and the ends of the connecting body on both sides and the corresponding graphite electrode thread groove are axially provided with a gap; the middle cylinder and the connecting body on both sides are axially provided with flow channels, The middle cylinder is radially provided with pouring holes communicating with the flow channels. The present invention optimizes and improves the traditional graphite electrode joint, so that the two graphite electrodes are connected more firmly, avoids the problem of tripping, and ensures the safety of use; for this purpose, an electrode group pair for connecting the graphite electrode joint and the graphite electrode is also designed. The device can quickly complete the pairing operation of graphite electrodes, which solves the trouble of traditional manual pairing, saves time and effort, and greatly improves the operation efficiency.

Description

technical field [0001] The invention relates to the technical field of graphite electrodes, in particular to a graphite electrode joint and an electrode group pair device. Background technique [0002] Graphite electrodes are mainly made of petroleum coke and needle coke, and coal tar pitch is used as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are released in the form of arcs in electric arc furnaces. Conductors that are heated and melted by electric energy can be divided into ordinary power, high power and ultra-high power according to their quality indicators. [0003] Due to the continuous consumption of graphite electrodes during work, the graphite electrodes are usually connected one by one. Usually, a taper threaded hole is processed at both ends of the graphite electrode, and then connected by the electrode joint. In the past, the electrode joint was usually two cones. The bodies are connected t...
