Melter Slag (MS)

Brief Description Melter Slag

spiegazione delle opzioni binarie Melter Slag is a co-product of the steel making process that converts iron sand to iron by adding coal and limestone. Melter slag differs from other slags in that the major oxides (calcium oxide and magnesium oxide) do not occur in their free form in the slag. Unlike conventional blast furnace slag (BFS), the iron sand-based material can not be granulated, which precludes its use as a cement replacement in concrete manufacture. صيغة ثيتا خيار ثنائي

Physical Description

This product consists of a high percentage of titanium and quantities of magnesium oxide and alumina typically higher than the industry norm. In contrast, the material has a characteristically low amount of silica, calcium oxide and sulphur.

Method of Manufacture

where can i buy Viagra in Cape Coral Florida Iron sands are mined using conventional earthmoving equipment before being separated magnetically, by creating a slurry and running it over magnetic drums. This is followed by gravimetric separation through a series of cones and spiral separators, where the heavier iron-bearing materials gravitate toward the centre, while residual clays and silts gravitate outwards. The slurry is then pumped 18 kilometres to the steel mill through an underground pipeline, where it is finally dewatered and stockpiled.

This drives off the volatile constituents of the coal. The material then enters one of four rotary kilns where the direct reduction takes place over a period of eight hours. The directly reduced product is then melted in one of two large electric melters.
