Use of alloy core wire in jet metallurgy technology
Jet metallurgical technology, as an important part of modern steelmaking technology, its development and improvement have played an important role in improving the quality of steel products, reducing production costs, and improving the production environment.In this technical system, alloy core wire (or cored wire), as a key refining method, is increasingly widely used and shows significant advantages.
Definition and composition of alloy core wire
Alloy core wire, also known as cored wire, is a composite material made by crushing various additives (such as deoxidizers, desulfurizers, metamorphic agents, alloys, etc.) to be added to liquid steel or liquid iron into a certain particle size and wrapping it in cold-rolled low-carbon steel strips.The cross-section of this material is usually round or rectangular, with any length, and can be flexibly adjusted according to actual production needs.
The use of alloy core wire in jet metallurgy technology
Refined liquid steel
The primary use of alloy core wire in jet metallurgy technology is to refine liquid steel.By directly adding the alloy core wire to the depths of the liquid steel, deoxygenation, desulfurization, degassing and deformation treatment of non-metallic inclusions can be effectively carried out, and the purity and quality of the liquid steel can be significantly improved.This process is not only conducive to the fine-tuning and control of the composition of liquid steel, but also can greatly improve the yield of alloying elements and reduce smelting costs.
Improve the castability of molten steel
The use of alloy core wire can improve the fluidity of molten steel, thereby improving the castability of molten steel.Especially in the continuous casting process, the alloy core wire can reduce inclusions in the liquid steel, avoid clogging of the spout, and ensure the continuity and stability of the production process.
Optimize the performance of steel
The alloying elements in the alloy core wire can significantly improve the mechanical properties, corrosion resistance and processing properties of steel.For example, adding an appropriate amount of calcium can optimize the morphology of inclusions in steel and improve the toughness and strength of steel; while silicon-calcium alloys can significantly improve the deoxygenation effect and thermal cracking resistance of steel.
Reduce production costs
The application of alloy core wire technology can significantly reduce alloy consumption and production costs in the steelmaking process.Due to the direct addition of alloying elements deep in the liquid steel, the burning and waste of alloying elements are reduced, and the utilization rate of alloying elements is improved.At the same time, the use of alloy core wire can also shorten the smelting time and improve production efficiency.
Improve the working environment
Compared with the traditional powder spraying method, the alloy core wire technology reduces the amount of powder added and the amount of flue gas generated, thereby improving the operating environment of the steelmaking workshop.This is not only conducive to the health of workers, but also reduces the cost of environmental protection.
