ALT (SGPT) Test. This blood test measures an enzyme called alanine transaminase (ALT). Enzymes are chemicals that help the cells of your body work. ALT is an enzyme made in the liver. It is released into the blood when tissues are damaged. This enzyme is also called serum glutamic-pyruvic transaminase, or SGPT.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
ORIGIN. Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.here are several different types of steel slag produced during the steel-making process. These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag.
