Electrode paste in the process of smelting silicon aluminum and iron

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 pressure of industrial policies have prompted the production of silicon-aluminum-ferroalloy furnaces to gradually become larger. Everyone knows that more than 50% of the production cost of ferroalloys is electricity consumption, while the electricity consumption per ton of large electric furnaces is significantly reduced. As one of the more difficult to smelt ferroalloys, silicon-aluminum-ferroalloys are used for smelting the electrode paste closed paste submerged arc furnace each time the electric furnace capacity increases is a major technological leap. This article summarizes the problems that should be paid attention to in the process of smelting ferro-silicon-aluminum alloy on the 16.5WVA electrode paste submerged arc furnace, in order to provide some references for the smelting of ferro-silicon-aluminum alloy. Device parameters (1). Furnace type: 16.5MVA submerged arc furnace (2). Transformers: Three 5500KVA single-phase smelting transformers are distributed in triangles. (3). Diameter of polar center circle: adjustable from 2700mm-3000mm. (4). Electrode diameter: 1150mm. (5) Hearth diameter: 6000mm. (6) Furnace depth: 2400mm. (7) Grip system: corrugated pressure ring gripper.

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...
