Basic Oxygen Process

แปลว่า(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).

Acid Process 1

แปลว่า(english) A process of making steel, either Bessemer, open-hearth or electric, in which the furnace is lined with a siliceous refractory and for which low phosphorus pig iron is required as this element is not removed.

Basic Oxygen Furnace (BOF)

แปลว่า(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Brazing

แปลว่า(english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet.

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.

gas furnace

แปลว่าเตาหลอมโลหะใช้แกสเป็นเชื้อเพลิงหมุนเวียน

open-hearth furnace

แปลว่าเตาหลอมเหล็กกล้าที่มีช่องเปิดพื้นใต้เตา

Breakout

แปลว่า(english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace.

Portland Blast- slag Cement Furnace (ASTM C 595)

แปลว่า(Concrete Engineering) The product obtained by intimately intergrinding or an intimate and uniform blending a mixture of granulated blast furnace slag and portland-cement clinker
