- Q: The reason why graphite is used as electrode
- Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
- Q: Synthesis techniques of carbon nanotubes
- Carbon nanotube discharge using graphite electrode is one of the earliest studies in various synthetic techniques. The researchers did a lot of work in optimizing arc discharge for carbon nanotubes. In recent years, in addition to people by adjusting the current and voltage, pressure and velocity change, change the electrode composition, improved electrode feeding mode optimization of arc discharge process, but also through changes the arc medium, simplified arc device. In the process of preparing carbon nanotubes, arc method is mature by changing the arc discharge conditions, catalyst, electrode size, feed mode, the distance between the poles and the raw materials. The carbon nanotubes formed by arc method are straight and wall (multi wall or even single wall). But the production rate is low, the arc discharge process is difficult to control, and the preparation cost is too high. The industrial scale production needs to be explored.
- 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: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
- Graphite electrode is mainly in petroleum coke, coke as raw material
- Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
- Q: Can high-purity graphite be used as an electrode?
- The utility model has the advantages of small density and suitable tool electrodes for processing large parts or moulds, and the whole quality is small.
- Q: Graphite electrode press device
- Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
- Q: What kinds of carbon are there?
- The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q: What about graphite electrodes for steel mills?
- The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
- Q: How do graphitized electrodes differentiate between high power and low power?
- In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.
