Do you know the advantages of Graphite Electrodes?

Graphite Electrodes refers to a kind of refractory made of petroleum coke and pitch coke as aggregates and coal tar as a binder. High-temperature graphite conductive material. Graphite electrode is mainly made of petroleum coke and needle coke, coal tar is used as a binder, and it is made by calcining, batching, kneading, pressing, roasting, graphitization and machining. The conductors that heat and melt the furnace charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra high power graphite electrodes according to their quality indicators.

The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required when producing high-power or ultra-high-power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and the sulfur content is controlled to be not more than 1.5% to 2%. Petroleum coke and pitch coke should meet the relevant national quality standards.
As a Graphite Electrodes Manufacturer, share with you the advantages:
(1) The increasing complexity of mold geometries and the diversification of product applications have led to higher and higher requirements for the discharge accuracy of spark machines. The advantages of graphite electrodes are that they are easier to process, have a higher removal rate of electrical discharge machining, and have less graphite loss. Therefore, some group-based spark machine customers have abandoned copper electrodes and switched to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to mold, and copper electrodes are heavier and are not suitable for processing large electrodes. These factors have caused some group-based spark machine customers to use graphite electrodes.
(2) Graphite electrodes are easier to process, and the processing speed is significantly faster than copper electrodes. For example, milling graphite is used to process graphite, its processing speed is 2 to 3 times faster than other metal processing and no additional manual processing is required, and copper electrodes need to be frustrated by hand. Similarly, if a high-speed graphite machining center is used to manufacture the electrodes, the speed will be faster, the efficiency will be higher, and the problem of dust will not occur. In these processes, the selection of tools and graphite with appropriate hardness can reduce tool wear and copper electrode breakage. If you compare the milling time of graphite electrodes and copper electrodes, in particular, graphite electrodes are 67% faster than copper electrodes. In general, electrical discharge machining using graphite electrodes is 58% faster than using copper electrodes. In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced. Our company has RP Graphite Electrodes on sale, welcome to consult

What are Graphite Electrodes and Needle Coke?

图片
  As a   Graphite Electrodes Manufacturer , share with you. Graphite electrodes are the main heating element used in electric arc furnaces, which is a steelmaking process that melts scrap from old cars or old home appliances to produce new steel. The construction cost of an electric arc furnace is cheaper than that of a traditional blast furnace, which is made of iron ore to make steel and is fueled by coking coal. However, steelmaking costs are higher because they use scrap steel and are driven by electricity. Graphite Electrodes The electrode is a part of the furnace cover and is assembled into a cylinder. Then, the current passes through the electrodes, forming a strong arc, melting the scrap. The size of the electrodes varies greatly, but the diameter can reach 0.75 meters (2 and a half feet), and the longest can reach 2.8 meters (9 feet). The largest weighs more than two metric tons. Up to 3 kilograms (6.6 pounds) of graphite electrodes are required to produce one ton of ...

How to Deal With the Details of Graphite Electrode Use?

图片
  As a   Graphite Electrodes Manufacturer , share with you. We need to know that the wet graphite electrode should be dried before use, and the internal thread of the electrode hole should be checked for integrity. When we clean the surface of the spare graphite electrode and the internal thread of the hole with compressed air, there must be no oily water; avoid cleaning with steel wire or metal brush cloth. Graphite Electrodes It is important to carefully screw the connector into the electrode hole of the spare graphite electrode, and screw the electrode strap (graphite strap is recommended) into the electrode hole on the other end of the spare electrode. When lifting the electrode, the cushion is soft to the bottom of one end of the spare electrode assembly connector to prevent ground damage and connector damage; the lifting hook extends to the lifting ring of the lifting device to lift, the lifting electrode is smooth, preventing the electrode from being released from the B...

Do you know the Bending Strength and Average Particle Size of Graphite Electrode Materials?

图片
  As a   Graphite Electrodes Manufacturer , share it with you. The bending strength of graphite electrode materials and the bending strength of graphite electrode materials are a direct reflection of the strength of the material, reflecting the compactness of the internal structure of the material. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high purity, or carbon fiber, the added value is high. Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000℃. It is easy to oxidize at high temperatures.  Graphite Electrodes Except for vacuum, it can only be used in neutral or reducing atmospheres. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extre...
