| Basic Oxygen Process | (english) (BOP) A process in which molten steel is produced in a furnace by blowing oxygen into molten iron, scrap and flux materials. The furnace is known as Basic Oxygen Furnace (BOF). |
| Basic Oxygen Process 2 | (english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel. |
| Basic Steel | (english) Steel melted in a furnace with a basic bottom and lining and under a slag containing an excess of a basic substance such as magnesia or lime. |
| Basket Screen | (english) A first stage in-line water filter for water delivered from the New Blowing Room Pump Room to the Blast Furnace. The strainer contains an electric-driven rotary sieve that catches particulates and prevents them from entering the water system. |
| Bastard | (english) Threads,parts,tools and sizes that are not standard, such as, “Bastard Nuts”, “Bastard Plus”, “bastaard fittings and so forth. The term also refers to a standard coarse cut file. |
| Batch Anneal | (english) The process by which a large, stationary stack of steel coils (4 coils high) is subjected to a long heat-treating cycle. This process enables the cold-rolled sheet to fully recrystallize into the softest possible product conforming to customer specifications. Controlling the recrystallization process makes a fine-grained microstructure easy to obtain, and minimizes the tendencies for retention of directional properties of the rolled steel which could produce undesirable shapes in the stamping of a cylindrical part such as a can. Also see Anneal and Continuous Anneal. |
| Batch Oven | (english) Oven use to bake a number of cores at one time. |
| Bath | (english) Molten metal on the hearth of a furnace, in a crucible, or in a ladle |
| Bath Annealing | (english) Is immersion is a liquid bath (such as molten lead or fused salts) held at an assigned temperature-when a lead bath is used, the process is known as lead annealing. |
| Bauxite | (english) The only commercial ore of aluminum, corresponding essentially to the formula Al2O3xH2O. |
