Q:How to solve the problem of graphite electrode being crushed during electrolysis
This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive
Q:Why should graphite paper be placed between the heater and the graphite electrode?
. Different single crystal furnace heaters may be of the same size or may be different. The heater is determined according to the size of the Czochralski single crystal furnace and the parameters of the drawn single crystal, and is generally designed in the form of a parallel circuit, and the following parameters. A heater, the heater, the shape of two inner diameters of three, four, the effective length of the heater heater, the heater piece is five thickness and gives the heater diameter. These parameters are determined according to Czochralski single-crystal furnace parameters and its crystal diameter. The power transformer parameters are mainly based on the single crystal furnace heating power: maximum output power, maximum output voltage and maximum output current, diameter and height of the crucible. The design of the heater has the following steps: 1. Selecting and determining the shape of the heater; the heater is made of high purity graphite; the resistivity of the high purity graphite; the heater is usually made into a cylinder at present.
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
Q:Why graphite can be used as conductive material?
Widely used as electrode, graphite, carbon brush, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating and so on in the electrical industry. The most widely used in the smelting of graphite electrode, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to around, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace used for the production of rigid sand is also made of graphite electrode as the conducting material of the furnace head.
Q:Carbon graphite electrode and what is the difference?
Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;
Q:The difference between graphite electrode and graphite rod
Graphite rod for non metal products, as carbon arc gouging cutting process in an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, is not easy fracture, suitable for metal cutting into required shape.
Q:Will the brush grease not short-circuit the commutator?
The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand
Q:Can high-purity graphite be used as an electrode?
The thin and deep bone electrode can not be deformed, and the pure graphite electrode is brittle. It is better to break or deform, and can bear high temperature without deformation.
Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
Graphite electrode should be relatively pure, composed of graphite.
Q:800KVA and 12500 EAF transformer data graphite electrode furnace.
Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.
