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 clayfilled iron notch at the base of the hearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flows into the clayfilled iron notch at the base of the hearth. During casting, molten iron flows ...

 · In this research, ammonium chloride was used to calcine Tiextraction blast furnace slag (EBFS) with the aim of removing iron from it. The influences of calcination temperature, ammonium chloride to EBFS mass ratio and particle size on the rates of iron removal were investigated. The results show that the rate of iron removal increased to almost with increases in calcination .

1. Use Chemical to Remove the Slag. To remove weld slag, chemical methods are also suggested. But sadly, the success rate is negligible because it is very difficult to remove using the most available acid pickling products. One of the main reasons is that slag is alkaline in nature. It is present as a thick layer. Hence, the acid pickle attacks ...

Slag recycling. With smelting slags, two approaches are available in principle for recycling. Recovery of the ferrous and nonferrous metals and also the use of the pure, metalfree slag itself as a secondary construction material. The recovery of the metals can be implemented using ferrous and nonferrous metal separators adapted to different ...

Iron recovery from a lead slag in Henan province was carried out with the technique of coalbased direct reduction followed by magnetic separation. Scanning electron microscopy (SEM) was used to investigate the transformation of ironcontaining minerals and the particle size of metallic iron generated by coal reduction. The results showed that technique is feasible for iron recovery from the ...
