Blast Furnace Gas
แปลว่า(english) By-product gas created by the iron making process which is used as fuel for the boilers.
Blast Furnace
แปลว่า(english) 1) A furnace in which solid fuel (limestone, coke, iron ore) is combined with high-pressure, hot air blast (120,000 psi) to smelt ore in a continuous process (They are never stopped. They can be slowed down or idled). A Blast Furnace in the iron and steel industry is used to produce liquid iron.
Blast Furnace 2
แปลว่า(english) A vertical shaft type smelting furnace in which an air blast is used, usually hot, for producing pih iron.

Agglomerating Processes
แปลว่า(english) "Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition, so the powdery material usually is processed into larger pieces. The raw material's properties determine the technique that is used by mills. 1) SINTER Baked particles that stick together in roughly one-inch chunks. Normally used for iron ore dust collected from the blast furnaces. 2) PELLETS Iron ore or limestone particles are rolled into little balls in a balling drum and hardened by heat. 3) BRIQUETTES Small lumps are formed by pressing material together. Hot Iron Briquetting (HBI) is a concentrated iron ore substitute for scrap for use in electric furnaces.
Blister Steel
แปลว่า(english) High-carbon steel produced by carburizing wrought iron. The bar, originally smooth, is covered with small blisters when removed from the cementation (carburizing) furnace.
