PapCal and HDx are a new generation of core wires that are used in liquid steel production to enhance the casting quality of steel. These wires decrease the calcium content in the liquid metal significantly which results in higher yields and improved characteristics of steel cast.
These wires are better in terms of their metallurgical properties in comparison to conventional CaSi or AlCaFe wires used for the treatment of calcium. They offer better steel casting properties and machinability as well as less slag injection volume and, in turn, reduce the amount of calcium consumed for tons of molten steel.
Pure Calcium Cored wires are able to be introduced through the ladle with the existing equipment. They do not require to change the process in the steel mill. They have the same diameter that the traditional calcium-based wires and can be fed with the same rate of feed. This new core wire contains a very dense and high-purity calcium powder that is encapsulated within a stainless steel casing. The thickness of the shell differs according to the wire's diameter. This core wire is stronger and more heat resistant as compared to the steel calcium wires from the previous.
That means that when the cored wire is inserted into the steel that is molten, it is able to melt quicker than the surrounding solid steel and the calcium-containing metal in the core will be able to absorb the slag oxygen and sulphur. This chemical exchange between the core with the that is melting metal will reduce the rate of oxidation for both elements, in addition to the viscosity of slag, and thus results in a better calcium treatment.
Cored wires are also used in other metallurgical applications like the de-oxidation process of liquid steel, adding of ferroalloys and refining. These new cored calcium wires have the ability to dramatically improve the quality and shape of inclusions within casting steel.
Core wires are an essential technique in the industry of steel since they can improve the final product's quality. Additionally, it can increase the efficiency of the steelmaking process through reducing the time it takes to cast the steel. The wire can be packed into paper boxes, steel drums, or plastic spools, based on the request of the customer.
