High-standard airtight paste produced by ferronickel

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.

Performance of high-standard sealed electrode paste The high-standard sealed electrode paste produced by Gongyi Rongxin Carbon is particularly suitable for smelting ferronickel electric furnaces. On the 3300KVa nickel-iron submerged arc furnace of a company in Jiangsu, the quality of Rongxin carbon electrode paste was verified using the results of tracking research. And it has been affirmed by Hu Lingbiao, an expert in nickel-iron smelting technology: the special closed electrode paste has high density, low ash content, high strength, low specific resistance, and good electrical and thermal conductivity; it has good resistance to rapid cold and heat, and can effectively prevent the electrode from soft breaking. Hard break, oxidized honeycomb and chip off. The high-standard sealed electrode paste supplied by Gongyi Rongxin Carbon is positioned as a series of high-quality sealed paste products due to its low ash and volatile content, low softening temperature and specific resistance, high compressive performance and true specific gravity. The electrode paste of this series is very suitable for working in the state where the nickel-iron submerged arc furnace needs to quickly complete the roasting of the characters. The high-standard sealed electrode paste produced by Rongxin Carbon is welcomed by large-scale sealed furnaces and ferroalloy companies that consume fast electrode materials, and is affirmed and favored by submerged arc furnace manufacturers that produce ferronickel.

Matters needing attention when filling electrode paste

Image
 The following points should be paid attention to when installing the electrode paste airtight paste: 1. Do not allow debris to enter the electrode 2. Proper paste height 3. Work harder 4. Appropriate temperature 5. Prevent overhang Before filling, the electrode paste should be broken, generally broken into small pieces of 80~100mm, so that the electrode paste block can pass between the two ribs smoothly. If the particle size is too large, the electrode paste suspension failure is likely to occur; if the particle size is too small, it is easy to cause the phenomenon of spraying. Use a forklift truck or special tools to transport the electrode paste to the calcium carbide furnace, and use an electric hoist to hoist the electrode paste into the electrode bucket. Pay attention to the safety of hoisting during loading. When installing electrode paste, be careful not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid accidents of electric fire. ...

The installation of cathode carbon block 1

Image
 　　The cathode carbon block and cathode steel bar are closely combined into one process. Cathode carbon block is an important part of aluminum reduction cell, which is directly used as cathode lining and conductive material. The cathode circuit of aluminum reduction cell is formed by connecting cathode steel bar and cathode bus. The assembly process of cathode carbon block and cathode steel bar should reduce the contact resistance between them as much as possible. 　　There are three ways to assemble cathode carbon block and cathode steel bar( 1) Cast iron casting method. The gap between them is cast with molten phosphorus pig iron, which is condensed to form a whole( 2) In the carbon paste tamping method, the gap on both sides of the steel rod is filled with cathode paste called steel rod paste, and tamped and compacted with pneumatic tools( 3) Bonding method. The cathode carbon block and steel bar are bonded together with carbon glue or adhesive. Graphite or metal pow...

Storage and management of electrode paste

Image
 As the self-baking electrode of submerged electric furnace, electrode paste has been widely used in the smelting of various products of submerged electric furnace. Although the cost of electrode paste in the production of calcium carbide, ferroalloy and other products is relatively low, the quality of the electrode paste and the firing of the electrode directly affect the stability of the operation of the submerged electric furnace. Due to the various types of submerged electric furnaces, the different furnace conditions, and the increasing capacity of electric furnaces, when the quality index of the electrode paste meets the requirements, the roasting quality plays a decisive factor, which requires us to focus on calcium carbide, ferroalloys, etc. The actual production of the product starts with the management of the electrode paste, strictly implements the operating procedures, regularly and quantitatively lowering the electrodes, and maintains the normal and stable operating pa...
