Slag can reduce furnace heat absorption, raise exit gas temperatures, increase attemperator spray-flow temperature, and interfere with ash removal or equipment operation. Slag is the formation of molten ash that is either partially fused or re-solidified ash deposits (ash fusion), formed based on the ash temperature and composition.

With a newly installed silica lining, melting capacity is 1,525 tons/month with two furnaces running five days/week, 21 days/month.
Induction furnace slag (IFS) collected from a steel manufacturing plant was in the form of large slag chunks. Collected slag chunks were crushed in the mechanical …
At the same time brick mortar crushing and pull strengths improved by 10–13% at 50–75% replace-ment levels. The study concluded that, granular slag could ... 30%, 40%, 50% and 60% induction furnace slag. Compressive strength tests on mortar and con-crete were conducted and the obtained results indicated that ... Testing method and procedure
Slag of induction furnace is crushed in pulverizer. These pulverizer is generally used to make powder of hardened sand mould. Crushing is done by means of hammer mounted on roller. Metal is separated by use of plate type magnetic separator. Used for lifting & …
The paper presents examination of actuation warmer slag of ferrous foundry at Jadhao Steels and Alloys . From the results of the present study we can say that Induction Furnace Slag contain 12.5 percent of metal so that it minimize the adverse impact of disposal on the environment. IndexTerms – Electric induction furnace, Metal, Slag, Steel
The thermal conductivity and microwave heating uniformity of asphalt mixtures basically decrease with the increase of steel slag content; while the surface temperature presents a contrary trend. Consequently, the suggested steel slag volume content is 40% and 60%; and the particle sizes of steel slag are selected as 9.5 mm, …
Fig. 4 (a) shows the result of direct refining of the crushed silicon slag with the intermediate frequency induction furnace. The aggregation of MG-Si did not take place and the result indicated that MG-Si could not be moved effectively due to the electromagnetic forces generated by the medium frequency induction furnace because …
