 The reason for the soft fracture of the electrode paste is quite right. Generally speaking, there are mainly the following aspects: (1) The electrode paste contains too much volatile matter. (2) The iron plate of the electrode shell is too thin or too thick. Too thin will not be able to withstand large external forces and rupture, causing the electrode iron shell to fold or leak and softly break when pressed and put; too thick will cause the iron shell and the electrode core to not contact closely and cause the core to cross. It will also cause soft disconnection. (3) Poor production of the electrode iron shell or poor welding quality will cause cracking, which will lead to leakage or soft fracture. (4) When the electrode is lowered, the load of the electric furnace is not reduced or reduced too little. After the electrode is discharged, the load increases too fast, which will also cause the electrode to softly break (except for large furnaces). (5) The electrode is lowered too freque

The nickel pig iron base material produced by the nickel-iron electric furnace has made an important contribution to the development of stainless steel. In the production of submerged arc furnaces in 2012, nearly 3.95 million tons of high-grade ferronickel base materials were continuously sent to stainless steel plants, ensuring a substantial increase in stainless steel output by 11.69%. In recent years, TISCO and Baosteel have used nickel metal in the total nickel pig iron, and the market has accounted for 30%-50% of the total nickel metal consumption. The high-standard sealed electrode paste produced by Rongxin Carbon in Gongyi City can ensure the long-term continuous and stable operation of the nickel submerged arc furnace.

It is more difficult to smelt silicon-aluminum-ferroalloy in a closed electrode paste submerged arc furnace, and only a good start can make the future smelting road smoother. Therefore, adequate preparation, high-quality raw materials, careful operation, and excellent technology are all necessary guarantees for opening the furnace. The ferrosilicon-aluminum alloy produced by the submerged thermal method, as a steelmaking deoxidizer, has been gradually recognized by major steel mills and more and more manufacturers because of its good deoxidizing effect and can effectively reduce steelmaking costs. At present, the types of furnaces for the production of ferrosilicon-aluminum alloys are mostly concentrated in the range of 1800KVa to 6300kVA. Its production capacity accounts for more than 80% of all submerged arc furnaces producing silicon-aluminum-ferroalloys, and its smelting technology in small furnaces is also becoming more mature. However, the rise in electricity prices and the pre

 With high quality anthracite, coke, graphite as raw materials made of carbon block. Used as cathode of aluminium electrolytic cell. It is built at the bottom of the electrolytic cell, also known as the bottom carbon block. The cathode carbon block plays a dual role of conducting electricity and forming the inner lining of the electrolytic cell. The cathode carbon block is required to have high temperature resistance in aluminum electrolysis production, resistant to molten salt erosion, good electrical and thermal conductivity, high mechanical strength, good thermal shock resistance and strong corrosion resistance of sodium, which is conducive to energy saving and tank life improvement in the production of aluminum electrolysis. According to the quality requirements of the products, the raw materials selected and the technological conditions used, the cathode carbon blocks in China are basically divided into three categories: ordinary cathode carbon blocks, semi-graphitic carbon b
