Graphite electrodes are used mainly in electric arc furnace steel production. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. HP Graphite electrode has good electrical properties and chemical stability. What’s more, graphite electrode has advantages of high mechanical strength, low impurity content and good vibration resistance. Graphite electrodes are good conductors of heat and electricity. Graphite electrode is widely used in steelmaking electric furnace, refining furnaces, production of ferroalloy, industrial silicon, yellow phosphorus, corundum , submerged arc furnaces and other smelting furnaces that produce high temperatures by electric arc. According to the different of service power and electricity , ...

1. Diverse mold geometry are complicated and product application requirements for the accuracy of EDM discharge leads to more and more high. The advantages of the graphite electrode is easy processing, high removal rate of graphite EDM, small loss, therefore, some group based spark machine spark machine customers give up copper electrode instead of graphite electrode . In addition, some electrode the special shape of the cannot be made of copper, but the graphite is easily molded, and the copper electrode is heavy, not suitable for processing large electrode, these factors have caused some group based spark machine spark machine application of graphite electrode. 2. HP Graphite electrode is easy to processing, and the processing speed is obviously faster than the copper electrode. For example, the milling of graphite, the processing speed is 2~3 times faster than other metal processing and does not require additional manual processing, and the copper electrode needed...

The refractory and the erosion resistance of the refractory can be obtained by selecting the high quality refractory material and having the proper proportion and strong tamping, Compared with refractory castable and plastic, it has high stability and corrosion resistance at high temperature. However, the service life depends largely on the pre sintering of the used or the amount of sintering used for the first time. If the heating surface is sintered as a whole and cracked and not separated from the bottom, the service life can be improved. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc. Article Source: Property and application of refractory ramming mass Company name: Wanhao Refractory Email:sales100@wanhaorefractory.com Website: http://www.wanhaorefractory.com/           ...

The mixer is mainly used for long-term storage of hot metal and maintain appropriate temperature of iron smelting . When working,generally the temperature in mixer keep 1350 degree temperature and furnace shell is 300-400 degree. When pouring into the hot metal mixer, because of the larger gap, hot metal will produce mechanical impact on the furnace lining.In addition, in order to keep the molten iron temperature in the furnace, the fuel must be injected into to take the flame heating, which also has a certain thermal stress effect on the lining material. According to the mixer working environment and damage reason, it can be analyzed that for the refractory material , it need high mechanical strength, high slag resistance, good thermal shock resistance, low thermal conductivity and small reheating linear change. Refractories are often used magnesia brick, magnesia chrome brick, high alumina brick , clay brick and refractory filler. At the same time as the mixer h...

Chrome corundum brick is alumina - chrome oxide as the main raw material production of high-performance, has the characteristics of high refractoriness , greatstrength, good thermal shock stability, strong ability to resist erosion, inuse, has the performances of scouring resistance, wear resistance, resistanceto spalling structure, has obtained the good effect in metallurgy, glass,carbon black, the petrochemical industry. Chrome corundum brick using rawmaterial is by the ratio of alumina and chromium oxide according tocertain proportion, go through high temperature melting synthesis of a solidsolution. Use special refractory materials production technology to makerefractory brick, can improve and enhance internal quality of the products,improve the high temperature performance of products. 1.Refractoryproperties of chrome corundum brick AddCr2O3 to high purity corundum material, no matter how much the amount is, notonly will not reduce the fire performance of materials...

The main factors that affect the service life of tundish castable safety layer are casting, sintering and using. 1.Casting. During casting, if the water added is more than it should be, or the vibration is not even at some parts, there will be more pores, which would cause partial stress concentration and aggregate segregation, the hardness of safety layer would not be enough, which affects the quality of the whole safety layer. 2.Sintering. If there is bad exhaust, rapid temperature rise during sintering, it will cause partial stress concentration and rapid expansion, stress is over the limits which the tundish castable can endure, partial collapse would appear. 3.Using. The damages during using are mains as erosion, sintering, carbonization, cracking, spalling, even partial collapse caused by the erosion of molten steel as the heats go by. The main reason is slag erosion under high temperature. Article Source: T he ...
