Corrosivity: Blast furnace slag is mildly alkaline, with a pH in nonstagnant water mixtures in the range of 8 to 10. Despite the fact that blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate is slightly alkaline and does not present a corrosion risk to steel (e.g., steel .
The shape and physical characteristics of iron and steel slag are similar to ordinary crushed stone and sand, however due to differences such as the chemical components and cooling processes, it is possible to provide different types of slag with a wide variety of unique properties.

The outer shell is made of steel and the inside of refractory brick. All ingredients are charged in the top of the stack. At the bottom, there are two discharging spouts, one for the cast iron, and one for the slag. Ingredients are pig iron, iron or steel scrap, limestone, and coke. The .
Steel slag aggregates are highly angular in shape and have rough surface texture. They have high bulk specific gravity and moderate water absorption (less than 3 percent). Table 18-1 lists some typical physical properties of steel slag. Table 18-1. Typical physical properties of steel slag.
For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 0.25 to 0.30 metric tons of slag per ton of crude iron produced. Steel furnace slag production, after removal of entrained metal, will be about 10 to 15 percent of the crude steel output.
Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore. The United States is also a major importer of iron and steel, as well as iron and steel products. Employment as of 2014 was 149,000 people employed in iron and steel mills, and 69,000 in foundries.

SLAG - IRON AND STEEL 16 Slag - Iron and Steel S lag is a by-product generated during manufacturing of pig iron and steel. It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making in blast furnace and steel manufacturing in steel melting shop.
The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium ...
