Graphite is an allotrope of carbon with a crystalline form and occurs in nature in the form of dispersed crystal flakes in high-grade metamorphic rocks, as veins, and as microcrystalline ‘amorphous’ graphite associated with metamorphosed coal seams Graphite possesses some useful properties which allow it to be used for a number of different uses across a broad range of industries. These properties consist of reactivity, lubrication, tolerance to extreme temperatures (for use in refractories) and strength. Most importantly, Graphite has some crucial conductive properties (known as reversible capacity) which makes it the most appropriate element for use as an anode material within Li-ion batteries. The Graphite market can be divided on the basis of product type and applications. On the basis of product type, the market can be divided into natural and synthetic. On the basis of applications, the market can be segmented into electrodes, foundries, recarburisers, batter

1. The graphite electrode must be covered with rainproof tent cloth during transportation. 2. Use a forklift to transport the stacking electrode. Only one layer is allowed at a time, and balance center should be watched to prevent it from falling. 3. When using a crane for loading and unloading, it is necessary to use a separate wire rope, and do not directly hook the steel packing tape of the electrode. 4. The graphite electrode should be stored in a clean, dry place. It must be covered with a rainproof cloth when putting it in open air. The stacking height should not exceed 4 layers. 5. The graphite electrode should be placed next to electric furnace for drying before use. The temperature should not exceed 150℃and the time should not be less than 24 hours. 6. When the graphite electrode is used, special tools are used to cut the steel tape and it must not be broken by a hoist. ----------------------------------------------------------------------------

With the continuous development of our country's industry, graphite electrodes have become more and more widely developed in the market, and gradually occupy the leading position in the market. However, when choose graphite electrode materials, how should we get the right one? We know that graphite electrode has a very high melting point, because it has extremely high heat resistance, can bear the current value, reduce the loss of the electrode, thereby further improving the production efficiency; but when the current value is very small, the loss of the electrode Will increase. When the area is constant and the pulse width is constant, the peak current will reach a certain value, continue to increase, and then the phenomenon of unstable processing occurs. The electrode and processing will produce arc burns, which will greatly reduce the production efficiency. The larger the current of the graphite electrode, the larger the pit of the electric erosion, so that a

The challenge is these Rebars are difficult to be counted manually at the plant, due to their high volume in numbers. The rate of production of Rebars is also high and thus there is a requirement to develop a method that will automatically count the Rebars quickly. Additionally, Rebars cannot always remain at the same level when they are strapped in a bundle. They are sometimes jutting out from the main bundle which adds to inconvenience. The Rebars are counted manually at distributors end when they form sub-bundles, which are then passed on to the Dealers. The Rebars finally get sold in the retail market in numbers. This is also a question which many rebar steel manufacturer meet together. Due to count by workers, one problem is low counting speed, the other problem is the low counting accuracy. From year of 2003, we have take this question as a study subject in China. As you know, China is also a big market for iron and steel industry. We collect technical data from l

Upon the request of rolling mill customer's demand, SINOM team developed the smarteye online inspection system. It is an online defect and dimension inspection system for plates, rods and wires and strip steels based on high-speed video. The system consists of visual system, cooling protective system, quakeproof system and mobile inspection system, which can inspect the surface defects, dimension of finished products and other parameters. It shall timely alarm the periodic defects caused by production technology, in order to improve yield of rods and wires, and subtract cost. Technical index 1. Wire rod diameter (or width): <300mm (it may customize visual inspection system); 2. Dimensional accuracy: 0.09mm (it may customize visual inspection system); 3. Defect accuracy: width >0.1mm (it may be customized according to users’ requirements); 4. Sampling frequency: 70,000 – 110,000 times/second; 5. Movement speed of rods and wires: 120m/s.
