Graphite electrode resistivity detection device

Abstract

The invention discloses a graphite electrode resistivity detection device, and the device comprises an upper hanging plate, a driving motor and a detection table, a sliding rod is arranged in the upper hanging plate, a sliding groove is formed in the upper hanging plate, a sliding plate is connected in the sliding groove, the sliding plate is installed outside the sliding rod, and a poking rod isarranged outside the upper hanging plate; the bottom of the poke rod is connected with a connecting rod, the connecting rod is located in the upper hanging plate, a positioning rod is arranged outsidethe connecting rod, and the positioning rod is located in the upper hanging plate. According to the graphite electrode resistivity detection device, the two sleeve rods sleeving the screw rod relatively move through the threads in the opposite directions on the two sides, and the sleeve rods move to drive the clamping rings to move, so that the wide distance between the clamping rings can be conveniently adjusted according to the size of a graphite electrode, and the graphite electrode can be conveniently fixed by the clamping rings; and the graphite electrode does not deviate during detection, so that the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of graphite electrodes, in particular to a graphite electrode resistivity detection 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. Graphite is very common in nature, and graphene is the strongest substance known to human beings. The resistivity contained in graphite electrodes is a physical quantity used to represent the resistance characteristics of various substances. The ratio of the product of the resistance and the cross-sectional area to the length of the original made of the substance is called the resistivity of the substance, and the graphite electrode is a conductor of the resistivity. [0003] 1. In the existing graphite electrode res...
