Specification introduction and usage method of ferroalloy cored wire

The cored wire is a kind of iron alloy. Various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) Composite materials made of any length mainly include three aspects: inoculation, out-of-furnace refining and special element alloying.

The types of cored wire include: dicalcium wire, pure calcium wire, calcium silicon wire, calcium aluminum wire, rare earth wire, titanium iron wire, carbon wire, etc.

Cored wire is suitable for steelmaking and foundry. It can purify the form of inclusions, improve the castability of molten steel, improve the performance of steel, significantly increase alloy production, reduce alloy consumption, reduce steelmaking costs, and achieve significant economic benefits.

1. The cored wire ferroalloy is also conducive to the adjustment and control of the content of oxidizable elements and trace elements, which can greatly increase the output of the alloy, reduce the cost of smelting, shorten the time of smelting, and accurately control the composition.

2. The cored wire plays a role in purifying molten steel and partially changing the nature and shape of inclusions, improving the quality of molten steel and improving the casting state.

3. Core-spun wire can be divided into two types: internal stretch and external placement. The mechanical equipment required for wire feeding is simple and reliable, and occupies a small area. In particular, inner drawn cored wire is more suitable for use in narrow places.

Core-spun wire has the advantages of uniform core material composition and high filling rate, and can be used in many industries, effectively reducing production costs and storage time during the smelting process.

In the manufacturer's steelmaking process, the cored wire can more conveniently put metallurgical materials into molten steel. It is used by inserting the cored wire vertically into molten iron or steel through the manufacturer's wire feeder. The metal material is fully melted at the ideal depth and produces a chemical reaction, effectively avoiding the reaction of the added elements with air and slag, and improving the absorption rate of the manufacturer's metal material. The cored wire also has the function of refining and precision casting to change inclusions, alloy and purify molten steel. It plays an important role in improving the quality of cast iron and cast steel, reducing the cost of casting and steelmaking, and improving the economic benefits of cast iron and cast iron. There are also many kinds of flux cored wire, including Si-Al-Ba-Ca flux cored wire, Si-Ca flux cored wire, Si-Ba-Ca cored wire, inoculant wire, spheroidizer wire, carbon wire, etc. Each type of flux cored wire has different uses and effects, so when choosing a flux cored wire, it is necessary to pay attention to selecting the appropriate flux cored wire according to the actual situation.

Si-Al-Ba cored wire is a ferroalloy product made by the manufacturer by mixing silicon powder, aluminum powder and barium powder and coating the steel strip. It is mainly used as deoxidizer and desulfurizer in steelmaking process.

Barium calcium silicate cored wire for deoxidation, desulfurization and other purposes is widely used by manufacturers in the steelmaking and foundry industries. Barium calcium silicate core wire can improve the anisotropy of steel in the manufacturer's steelmaking process. The manufacturer can use the wire feeder to quickly put the barium calcium silicate cored wire into the molten steel, and the ferroalloy can be quickly dissolved in the depth of the molten steel, reducing nozzle clogging, deoxidizing, desulfurizing and removing inclusions, and can fine-tune the composition to improve silicon The absorption rate of calcium carbonate and barium silicate and the yield of steel can reduce the production cost of the manufacturer and ensure the stability of the composition.
