金林供應增碳劑 無煙煤增碳劑95%含量 規格齊全一噸起訂
無煙煤增碳劑系煉鋼用添加劑,品質以固定炭(Fixed Carbon)含量高低為標準,分為特級(Fc≥95%)、一級(Fc≥94%)、二級(Fc≥93%)、三級(Fc≥90%),其中固定炭含量高於95%的特級增炭劑,增炭效果可與FC:98%的石油焦相媲美,其價格還不到石油焦的1/2,是國際上運用較廣泛的石油焦替代品。
無煙煤主要產自寧夏石嘴山,內蒙烏海。成分一般為C:90-93%,S0.3-0.5%。主要用於煉鋼企業使用,寧夏堿溝山的無煙煤,灰分小於7%,硫含量從0.6-2.9%,是不可多得的優質無煙煤。經煤科院北京煤化所,寧夏太西洗煤廠和包頭鋼鐵公司的驗證,寧夏無煙煤增碳劑有如下特點:
1 高變質程度的寧夏無煙煤經過降低灰分和熱處理後,可生產出高質量的煤質煉鋼增碳劑。
2 煤質增碳劑使用粒度為1-8mm,其增碳效果可與石油焦增碳劑相媲美。
3 采用煤質增碳劑煉鋼對鋼的化學成分,夾雜物總量,結晶度,晶組織的力學性能沒有影響,鋼的質量合格率為100%。
4 使用煤質增碳劑代替石油焦增碳劑煉鋼增碳,可以降低企業成本,提高企業經濟效益。
同樣的化學成分,采用不同的熔煉工藝、不同配料和配料比,鐵液的冶金質量完全不同。獲得好的滲碳效果,電爐采用的是增碳技術,沖天爐采用的是高溫熔煉技術。增碳劑對熔煉的影響主要有三方麵。
1.鐵液增碳技術,在熔煉過程中特別是電爐熔煉,可以增加石墨晶核。沖天爐熔煉中加入碳化矽還能增加鐵液的長效石墨晶核,同時減少鐵液氧化。
2.增碳是防止或減輕收縮傾向最好的措施。由於鐵液凝固過程中的具有石墨化膨脹的作用,因此良好的石墨化會減少鐵液的收縮傾向。
3. 在高的碳量條件下,為獲得高強度的灰鑄鐵鑄件,熔煉過程采用全廢鋼加增碳劑的工藝,使鐵液更加純凈,生產的鑄件材料性能高。

Anthracite recarburizer is additive in steel-making, quality by Fixed Carbon (Fixed) Carbon content is high and low for the standard, divided into premium (Fc 95% or higher) and level
(Fc 94% or higher), secondary (Fc 93% or higher), triple (Fc 90% or higher), Fixed Carbon content is higher than 95% premium increase Carbon agent, increased Carbon effect with Fc: 98% of petroleum coke, the price is less than 1/2 of the petroleum coke, is used more widely in the world petroleum coke substitute.
