SELECTION OF ELECTRICAL STEELS FOR Magnetic Cores

Silicon is the primary alloying element in electrical steels. It is added because it increases the volume resistivity of the steel and thereby reduces the eddy current component of core loss. Silicon is more effec-tive in this respect than any other element which may

Cored wire

Cored wire is used to inject a modifying material into molten cast iron. A cored wire is a hollow wire, approximately 0.3 mm thick, filled with a specific modifying agent based on the selected cored wire type. Appliion: Deoxidising and desulphurisation agent for furnaces used in the production of high-quality steel, in particular low-silicon steel, resulting in improved fusibility and casting.

Ladle Nozzle Clogging during casting of Silicon-Steel in: …

But the researchers thought that some steel with high silicon, such as welding steel, calcium should be not be added into the steel, because it can increase the welding cracks of the steel []. That meant that not all steel can use calcium-treatment for solving the clogging, and there has no been a research on ladle nozzle clogging of silicon steel.

Influence of the chemical composition on steel casting …

2017/1/1· In this outline, the inclusions in aluminium killed and calcium treated steel are spherical with a low-melting-point calcium aluminate core, covered by calcium and manganese sulphides. The inclusions at relatively-low melting point, smaller in size and spherical are recommended to improve the fatigue strength and toughness properties and also prevent or decrease the hydrogen erittlement [1

Welding Consumables - Part 2 - TWI

High welding currents can therefore be used without the risk of the core wire overheating, thus increasing both the burn-off and the deposition rates. The high recovery electrodes are ideally suited for fillet welding, giving a smooth, finely rippled surface with a smooth blend at the weld toes.
