hearth rug
แปลว่าพรมหน้าเตาไฟหรือเตาผิง
machinery steel
แปลว่า(เครื่องมือ) เหล็กกล้าที่ผ่านกรรมวิธี open-hearth process ซึ่งมีส่วนของคาร์บอน 0.15 ถึง 0.25 เปอรเซ็นต์ เป็นเหล็กดี
ore hearth
แปลว่า(แร่) เตาถลุงแร่ตะกั่ว
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.
hearth
แปลว่าพื้นหรือบริเวณใกล้เตาไฟ ใช้วัสดุ ทนไฟ เช่น อิฐ หินเตาผิง
open-hearth furnace
แปลว่าเตาหลอมเหล็กกล้าที่มีช่องเปิดพื้นใต้เตา
Acid-Process
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.
Bath
แปลว่า(english) Molten metal on the hearth of a furnace, in a crucible, or in a ladle
Acid Process 1
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. "
Basic Oxygen Process 2
แปลว่า(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.
