The service life of graphite crucibles

What aspects will endanger the use period of graphite board

First, the quality of the production and processing of graphite board is the direct cause of the life of the application of its application. Graphite board production and processing must be careful to reach the overall goal of the standard. For example, pre -immersing this level must be well -proportioned, so that its resistance is basically unremittingly consistent, so that the conductivity can be proportioned to prevent the entire production process from occurring in the process of production Some part is complete, but some of the erosion is serious, so that all personnel come out to consume.In the second place, the graphite board must have an excellent office environment, which is the fundamental to prolong life. During the entire production process, reduce the impact and clean up the office environment. It can check the power circuit on time, produce at the best temperature, and reduce the air oxidation of the gas to its air.In the end, high -quality graphite boards are used to im

What are the main applications of graphite electrodes in?

(1) Used for electric arc steelmaking furnaces. Electric furnace steelmaking is a major user of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace,Utilize the high-temperature heat source generated by the arc between the electrode end and the furnace material for smelting.(2) Used for submerged arc furnaces. The submerged arc furnace is mainly used for the production of industrial silicon and yellow phosphorus, and its characteristic is that the lower part of the conductive electrode is buried in the furnace material,Arc is formed within the material layer and the heat energy emitted by the resistance of the furnace material is used to heat the furnace material. A submerged arc furnace with a high current density is requiredGraphite electrodes are required.(3) Used for resistance furnaces. The graphitization furnace for producing graphite products, the furnace for melting glass, and the electric furnace for producing silico

How to measure the conductivity of graphite powder

Graphite powder has high conductivity. The conductivity of graphite powder is an important factor in the conductive finished product of graphite powder. There are many factors that affect the conductivity of conductive graphite powder, such as the ratio of graphite powder, external pressure, environmental humidity, humidity, and even light. The following methods can usually be used to measure the conductivity of graphite powder:1. Voltammeter method for measuring resistanceSpecific method: Use a precision small range electricity meter or a resistance multimeter to measure and compare the experiment. You can use a small light bulb to measure its conductivity based on its brightness. If the light bulb is brighter, it indicates a smaller resistance.2. Measuring the conductivity of conductive graphite powder through resin methodGo buy some resin for conductive paint, add the same amount of conductive graphite powder, and then apply it on a board to measure its conductivity using a digital

What is graphite

Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque solid, stable chemical properties, corrosion resistance, and it is not easy to react with drugs such as acid and alkali. Natural graphite comes from graphite ore. It can also be used as a raw material for oil coke, asphalt coke, etc., and made a series of processes to make a human -made graphite. Graphite is burned in oxygen to generate carbon dioxide, which can be oxidized by strong oxidant such as concentric acid and potassium permanganate. It can be used as an anti -wear agent and lubricant. High -purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, and arc
