Basic slag facilitates the transfer of both sulphur and silicon from the metal to slag but it also has higher viscosity. Low viscosity along with good transferability of elements favors the proper functioning of the blast furnace. The V-Ratio of the Hearth slag in the range of 1.0 and 1.25 fulfill these two contradictory requirements.

Slag-What is it Good for? | U.S. Geological Survey

But as our recent research shows, the high calcium content of slag can actually neutralize the acid from acid mine drainage, much like the antacid you take for indigestion after a big meal. Not only that, but it can even reduce acids that have built up in soils. We looked specifically at ferrous slag, the leftover material from the smelting of ...

16. Slag inclusion is also called as exogenous inclusion, entrapped slag. Slag Inclusion Defect 17. Raised mold defect. Because of the flotage of liquid metal, the mould flasks are raised, which caused the top part of casting become higher or thicker than lower part. Raised Mold Defect 18. Crack defects normally happen inside of metal castings.

Control of Slag and Insoluble Buildup in Ladles, Melting …

systems used by the U.S. foundry industry have changed significantly. During the same period, while ductile iron production has experienced continued growth, the quality of metallic scrap and other iron-unit feed stocks has steadily deteriorated. The result: slag related melting problems have become widespread issues in recent years.

Latest from Shakeout

By breaking down the gangly returns, furnace charging and melting becomes more efficient. For the typical iron foundry, density of the returns are typically increased by a factor of three, so the charge crane is able to lift more material, reducing trips by a factor of five. Having the returns broken down to more optimal sizes, the instances of ...
