Many enterprises use the wire-feeding method for nodularization when producing ductile iron pipe fittings on vertical flaskless molding lines. However, sometimes the lower castings in the same mold turn out to be gray iron, while the upper ones remain ductile iron. What could be the reason? This article will answer all your

IntroductionSilicon-calcium (Si-Ca) alloy is a critical additive in modern metallurgy, particularly in steelmaking and iron processing. Composed primarily of silicon and calcium, this alloy serves as a powerful deoxidizer, desulfurizer, and inoculant, significantly improving the quality and mechanical properties of steel. T

There are many types of cored wires. When calcium-silicon powder is rolled into a cored wire, it is called a calcium-silicon cored wire, also known as a calcium-silicon wire. It serves as an additive in steel production, beneficial for adjusting and controlling the content of easily oxidizable elements and trace elements. I

Advantages and Disadvantages of Core Material Preparation Methods for Cored Wire The so-called wire-feeding spheroidization (vermicularization or inoculation) refers to the process of wrapping core materials of specific composition and particle size into steel strips of certain thickness and width using a wire-coiling devic

IntroductionThe steel industry continuously evolves with advancements in material science and manufacturing technologies. Among these innovations, the use of “aluminum wire” (or aluminum cored wire) has gained prominence due to its significant role in improving steel quality, enhancing production efficiency, and

IntroductionCored wire technology is widely used in steelmaking for precise alloy addition, inclusion modification, and desulfurization. Two common types are “pure calcium cored wire” and “calcium-iron (CaFe) cored wire”, each with distinct advantages depending on the steelmaking process. This article compares their propert

IntroductionCalcium-coated cored wire is a critical material in modern steelmaking, primarily used for deoxidation, desulfurization, and inclusion modification. Its seamless design ensures precise calcium delivery into molten steel, improving efficiency and reducing waste. This article explores its functions and provides ke
