Broaching 2

แปลว่า(english) Multiple shaving, accomplished by pushing a tool with stepped cutting edges along the piece, particularly through holes.

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. The furnace is continuous in operation using iron ore, coke, and limestone as raw materials which are charged at the top while the molten iron and slag are collected at the bottom and are tapped out at intervals.

Boring Tool

แปลว่า(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.

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.

Bell Mouth

แปลว่า(english) The flaring or tapering of a machined hole, usually made at the entrance end because of misalignment or spring of the cutting tool.

Broach

แปลว่า(english) A long, tapered cutting tool with serrations which,when forced through a hole or across a surface, cuts a desired shape or size.

Broaching

แปลว่า(english) Smoothing machined holes or outside surfaces of castings by drawing pushing on or more broaches (special cutting tools) through the roughed out hole.

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.

Normal stress:

แปลว่า(english) Stress acting perpendicular to an imaginary plane cutting through an object. Normal stress has two senses: compression and tension. Normal stress is often simply called stress.

Bloom 2

แปลว่า(english) A semi-finished hot rolled product, rectangular in cross section, produced on a blooming mill. For iron and steel, the width is not more than twice the thickness, and the cross-sectional area is usually not less than 36 sq. in. Iron and steel blooms are sometimes made by forging.
