Most of the steel mills in Bangladesh use induction furnace which produces large quantities of slags that have very little use except land filling. Therefore, feasibility of using this slag is examined in concrete with recycled aggregate, which is another waste product that is generated due to removal of old structures. Concrete with three target …

Important aspects of operation. As liquid steel is excited by current opposite to current flowing in induction coil, it is agitated to raise its surface in the center. Surface of liquid steel is risen higher as frequency becomes lower, i.e. agitation of the liquid steel occurs stronger in low-frequency furnace than in high-frequency furnace.

Since steelmaking slag when it is formed, it is in a liquid or red-hot state at a temperature range of 1,300 deg C to 1,700 deg C, the slag is to be immediately subjected to the cooling process upon removal from the furnace. Normally, this is done in a cooling yard by air cooling and moderate water sprinkling.
