硅錳合金的用途

發布:安陽坤鑫達冶金耐材有限公司瀏覽:511次

  

  錳硅合金是煉鋼常用的復合脫氧劑,又是生產中低碳錳鐵和電硅熱法生產金屬錳的還原劑。硅錳合金廠家安陽坤鑫達冶金告訴您,它是由錳、硅、鐵及少量碳和其它元素組成的合金,是一種用途較廣、產量較大的鐵合金。


硅錳合金


  錳和硅是碳鋼中所用的主要合金元素。錳是煉鋼過程中主要的脫氧劑之一,幾乎所有的鋼種都需要用錳來脫氧。因為用錳來脫氧時所生成的氧產物熔點較低,易于上??;錳還能增大硅和鋁等強脫氧劑的脫氧效果。所有的工業鋼都需加入少量的錳作為脫硫劑,使鋼能進行熱軋、鍛造及其它工藝而不致斷裂,錳還是各鋼種中重要的合金元素,在合金鋼中也會添加15%以上的錳以增加鋼的結構強度。硅是生鐵和碳鋼中僅次于錳的重要的合金元素。在鋼生產中,硅主要用作熔融金屬的脫氧劑,或作為合金添加劑使鋼增加強度和改善其性能。硅還是一種有效的石磨化介質,它能使鑄鐵中的碳變成游離的石磨碳。加入標準灰口鑄鐵和球墨鑄鐵中的硅可達4%。而大量的錳和硅都是以鐵合金的形式添加到鋼液中的:錳鐵、硅錳和硅鐵。

  硅錳合金是在礦熱爐中用炭同時還原錳礦石(包括富錳渣)和硅石中的氧化錳和二氧化硅而煉制生產的。錳硅合金的生產在礦熱爐內進行,使用碳質還原劑、錳礦石、富錳渣、燒結錳礦、焙燒錳礦和硅石作原料,石灰、白云石、螢石等作熔劑在電爐內連續生產。

  安陽坤鑫達冶金耐材有限公司從事鐵合金、耐火材料、硅制品加工銷售,主要產品有:硅鋇鈣、碳化硅、金屬硅粉、硅鋇合金、包芯線、金屬硅粒、硅錳合金等,如您有產品需求,可與我公司聯系!http://www.centralpennbldgsvs.com/
