Steel, Abrasives and Foundry
The steel, abrasives, and foundry industries use a variety of chemicals and substances at different stages of the manufacturing process. These chemicals are essential for processes such as metal production, surface treatment, and casting. Here are some key chemicals used in these industries:
- Steel Industry
Coke and Coal: Used in the production of pig iron through the blast furnace process.
Limestone: Acts as a flux in the blast furnace, aiding in the removal of impurities during iron and steel production.
Ferroalloys: Including ferrochrome, ferromanganese, and ferrosilicon, which are alloying agents used to impart specific properties to steel.
Pickling Chemicals: Acids like hydrochloric acid or sulfuric acid are used for pickling steel to remove oxides and scales.
Degreasing Agents: Chemicals to remove oils and greases from steel surfaces before further processing.
Coolants and Lubricants: Used in various machining and forming processes to reduce heat and friction. - Abrasives Industry
Aluminum Oxide and Silicon Carbide: Common abrasives used in the manufacturing of grinding wheels, sandpapers, and abrasive tools.
Binders and Fillers: Resins and other additives used to bond abrasive grains together in coated abrasives.
Grinding Fluids: Coolants and lubricants used in grinding operations to improve efficiency and extend tool life.
- Foundry IndustryBinders and Additives: Used in the preparation of molding sand for casting processes.
Refractory Materials: Used to line furnaces and crucibles, providing resistance to high temperatures.
Core Making Chemicals: Chemicals used in the production of cores for casting.
Mould and Core Release Agents: Substances applied to moulds and cores to facilitate easy removal of the finished casting.
