refractory
แปลว่าวัตถุทนความร้อนสูง, วัตถุที่ไม่หลอมละลายเมื่อถูกความร้อน
แปลว่าดื้อรั้น, หัวดื้อ, หัวรั้น, ไม่อ่อนน้อม
แปลว่าซึ่งไม่ตอบสนองต่อการรักษา, ดื้อยา

Acid Process 2
แปลว่า(english) A steel making method using an acid refractory-lined (usually silica) furnace. Neither sulfur or phosphorus is removed.
Zircon
แปลว่า(english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries.
Zirconia
แปลว่า(english) ZrO2 an acid refractory up to 2500 B0C (4532 B0F) having good thermal shock resistance and low electrical resistively.
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.
refractory concrete
แปลว่าคอนกรีตทนไฟ
refractory brick
แปลว่าอิฐทนไฟ
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. "
