Calcium silicon cored wire is one of the most common types of metal wires available for sale. Its primary use is as a deoxidizer. It also reduces the temperature loss in molten steel. Additionally, it improves the shape of inclusions in metal. This article will provide information on this product and how it can benefit your business. Also, you'll learn how to find a reliable source to buy this wire.
Metallurgical calcium silicon cored wire is produced in various core diameters, with the ratio of the two diameters D2/D1 being between 1.3 and 6.2. These wires are then supplied in wooden pallets or steel frames to prevent their damage in transit. Moisture proof film is usually applied to the cored wire to prevent it from being harmed by atmospheric attack. For this reason, the cored wire should be stored in a dry and temperature-controlled area.
The thickness of the outer wire casing is 0.4 mm, which is similar to that of standard cored wire. Its filling consists of calcium and silicon powders, with a 30:70 ratio of calcium and iron. Its weight is about 275 g/m. The weight of the wire is approximately 374 mm per kilogram. The added calcium content was 12.9% and 4.3% respectively.
A calcium silicon cored wire is a deoxidizing agent applied to steel smelting production. Usually used for pipe line steel and cold heading steel, this material is also applicable to low-silicon steel. The core material of this wire is composed of calcium, and the process uses a vacuum. Its properties allow it to change the form of impurities in steel while making it more ductile.
The process of forming cored wire is a form of off-furnace refining, and is widely used in steelmaking. When the wire is passed through a slag layer at a certain speed, it reaches the bottom of a ladle containing molten steel. The additives in the wire interact with the molten steel, changing the composition, properties, and inclusions. In some environments, this process may be used to inoculate steel.
This research has revealed that a new method of feeding molten steel is better for improving the shape of inclusions. The new calcium silicon cored wire reduces the temperature loss of molten steel by more than 50%. Moreover, the wire is fed by wire feed method instead of a bulk alloy. This method reduces the investment and operation cost. Here is a detailed description of the process.
The cored wire is used in cast iron, desulfurization, spheroidization, creeping treatment, and inoculation. The standard used is different according to the process, but the absorption rate of Ca depends on feeding speed. A slow feeding speed can reduce the absorption rate. The depth at which core wire begins to melt must be sufficient to subject the calcium bubbles to a large hydrostatic pressure, causing the calcium to consume the calcium before floating to the molten steel.
A calcium silicon cored wire is a tool that is useful for improving the shape of inclusions. It is fed by wire, which reduces the investment cost and operating cost. Besides, the calcium treatment can modify the morphology of sulphides and improve the compatibility between the inclusion and matrix. It is used in hot deformation processes. Calcium silicon cored wire can improve the shape of inclusions as well.
Cored wire contains calcium that is added to the steel in stabilized form. It is a good choice for inclusion shape control because it modifies sulfide and oxide inclusions without affecting their total content. Calcium also helps reduce nozzle clogging, which is a common problem with some steels. In addition, the inclusions shaped with calcium are less harmful to the final product.
