A graphite electrode resistivity detection device

Abstract

The invention discloses a graphite electrode resistivity detection device, which comprises a hanging board, a driving motor and a detection platform. A slide bar is arranged inside the hanging board, and a chute is opened inside the hanging board. A slide plate is connected, and the slide plate is installed on the outside of the slide bar. A toggle rod is arranged outside the hanging plate, and a connecting rod is connected to the bottom of the toggle bar, and the connecting rod is located inside the hanging plate. A positioning rod is arranged on the outside, and the positioning rod is located inside the hanging plate. In this graphite electrode resistivity detection device, the two sleeve rods sleeved on the screw rod are relatively moved through the opposite threads on both sides, and the movement of the sleeve rods drives the movement of the clamping ring, thereby facilitating the adjustment of the clamping ring. The wide distance can be adjusted according to the size of the graphite electrode, which is convenient for the clamping ring to fix the graphite electrode, which is beneficial to prevent the graphite electrode from shifting during detection and improve the detection efficiency.

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...
