    In the second stage these slags were heated to between 1000 and 1200 degrees in a slag hearth to melt them entirely. In order to get such temperatures coke was used as fuel. Reverberatory or Cupola Furnaces. In the mid and north Pennines where coal was relatively expensive orehearths were used until the early twentieth century.

     · What is the cupola furnace explain with diagram A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron Niresist iron and some bronzes. The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from to 13 feet ( to m).

    Study on the Appropriate Production Parameters of a Gas

     ·  Heat taken away by molten iron slag and top gas. The temperature is higher when the molten iron and slag are out of the blast furnace and they will also take away some heat. The heat taken away by the top gas is affected by three parts water vapor dry gas and furnace dust. The algorithm is shown in formula 25.

    A Dynamic MixedControl Model for BOF Metal–Slag–Gas

    202138 · Basic oxygen steelmaking has been the interest of research for several decades due to its complex and fast process dynamics. To predict the evolution of slag–metal composition and temperature it is important to control the process efficiently. The framework developed by Sarkar et al. (Metall Mater Trans B 46 961–976 2015) is advanced further to estimate the evolution of chemical

    Analysis of Induction Furnace Slag of Ferrous Foundry

    201525 · Total slag produced leads to waste heat recovery of 2070 000 million KJ 5671x106 KJ per hour converted into terms of oil this rate is x106 kg/hr. So that for energy conservation the slag heat recovery is essential in Indian foundry sector. Thus there is large potential of energy conservation with slag heat reuse.

    Effect of Slag Compositions and Additive on Heat

    of slag rims poor lubrication uneven heat transfer and surface defects in the form of longitudinal and transverse depressions and cracks even breakouts are 4) These are indeed the issues that need to be overcome by clear and essential understanding the effect mechanism on slag properties of slag compositions changes due to slag/metal

    Slag Volumean overview ScienceDirect Topics

    Slag basicity is defined as the (CaO MgO )/SiO 2 ratio of the liquid. If this ratio exceeds 1 the slag is basic if it is less than 1 it is acidic. Basic slags can be obtained by charging the cupola with sufficient fluxes (limestone and dolomite) to ensure the required Ca and Mg content.
