中文拼音 [yǎngqìróngliàn]
氧氣熔煉
英文
oxygen smelting-
Oxygen - natural rotating gas furnace for cast iron melting
熔煉鑄鐵用氧氣183 ;天然氣回轉爐Abstract : during the heating of scrap with carbon or hydrocarbon contented substances in some process, it will bring problems like explosion of carbon monoxide, fume and smell from oil volatilization, etc. ， if incomplete combustion occurs. through laboratory experiments, the time related variation of gas contents and post combustion ratio of fume during the heating of oil - bearing scrap are studied. the results show that the restrictive chain of reaction procedure is the thermolysis of oil ; that temperature and ( co ) / ( co2 ) ratio influence transformation ratio and post - combustion ratio under lower temperature ; that 900 is the temperature above which the complete reaction can be ensured at all ( co ) / ( co2 ) ratios
文摘:在某些廢鋼熔煉過程中，當爐料中含碳及碳氫物質且燃燒不充分時，會帶來煙氣中一氧化碳的燃爆、油污揮發時造成的煙霧、臭味等問題.通過實驗室裝置研究含油廢鋼在加熱過程中煙氣成分隨時間的改變以及二次燃燒率的變化，試驗結果表明，反應過程的限制性環節是油分的熱分解；在較低的溫度下（ co ） / （ co2 ）比例影響轉化率和二次燃燒率；而在任意比例下保證充分反應的溫度為900以上The results showed that the melting ratio of silica flux decreases and the complete melting time prolongs with the size of silica flux and matte grade increasing, and the effect of the blowing air and oxygen enrichment is not remarkable in the high grade copper matte converting process
對于高品位冰銅轉爐吹煉，鼓入氣體流量和氧濃度對石英熔劑熔化率影響不顯著；熔劑粒度和冰銅品位對熔化率影響顯著，並隨著熔劑粒度和冰銅品位的增加，熔劑熔化率降低，完全熔化時間延長。Since its chemical character is very active, mg alloy is prone to oxidation and burning, which makes it impossible to be melted and cast in air
但由於鎂的化學性質活潑，非常容易氧化、燃燒，導致鎂合金無法在大氣條件下直接進行熔煉和澆注。分享友人
