2021-6-25  The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows

2021-1-21  Slag is drawn off from the top of the melt about once every 2 hr, and the molten iron itself is drawn off or tapped about five times a day. The air used to supply the blast in a blast furnace is preheated to temperatures between approximately 540 and 870 C (approximately 1000 and 1600 F).

Electrochemical characteristics of molten iron electrodes

2021-9-1  This work has measured electrochemical properties of molten iron electrodes in slag and electrochemical properties of the molten iron/slag interface. Kinetic processes including mass transport and faradaic reactions were examined at 1600–1700 °C through impedance spectroscopy performed at the rest potential and at applied direct current biases.

Interfacial phenomena between molten iron and molten

2021-1-13  The blue region is the molten iron, and the red region is the molten slag. The pure white curvature is the contour of the droplet, which corresponds to Gibbs’ dividing surface. The shape of the droplet was decided so that it satisfies the Laplace’s equation in which the balance between gravity and pressure difference are considered (Eq. 5).

Multicomponent diffusion in molten slags SpringerLink

A method for investigating the diffusion of metal cations in multicomponent slag systems was developed. This method used microprobe analysis and allowed the analysis of the diffusion of multiple species within a single system. This project focused on the diffusion behavior of manganese, iron, calcium, and silicon in silicate slags, in order to simulate industrial steel and ferromanganese
