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.
Liquid LD slag is produced during the LD process as pig iron is processed into crude steel. Slag is not a random product, but rather a consequence of the Linz-Donawitz process, which uses steel as well as LD slag.The slag is separated from the crude steel, separately processed, and its chemical composition analyzed.D slag is a byproduct of the Linz-Donawitz process and is constantly produced as pig iron is processed into crude steel.
