攀钢烧结配加高品位钒钛磁铁精矿试验研究

Experimental Study on Sintering by Adding High Grade Vanadium-bearing Titaniferous Magnetite Concentrate at Pangang

通过烧结试验,研究了攀西白马矿区兆洋高品位钒钛磁铁精矿的烧结特性。认为:采用兆洋高品位钒钛磁铁精矿替代攀精矿后,垂直烧结速度加快,利用系数提高,烧结矿强度及冶金性能改善。烧结配加20%兆洋高品位钒钛磁铁精矿工业试验表明,该矿有利于强化烧结生产,提高烧结矿质量,烧结矿品位提高了1.16个百分点,转鼓强度上升0.57个百分点,烧结固体燃料消耗下降1.46 kg/t。

Through sintering test,sintering performance of the high grade vanadium-bearing titaniferous magnetite concentrate from Zhaoyang of Baima Mine,Pan-Xi District was studied.Taking the place of Panzhihua concentrate,the Zhaoyang concentrate exhibited good performances in sintering,such as acceleration of vertical sintering speed,increase of utilization coefficient and improvement of strength and metallurgical properties of sinter.Results of industrial experiments suggested that addition of 20 percent of Zhaoyang concentrate instead of Panhihua concentrate to the feedstock contributed to improvement of sintering performance and quality of sinter,with TFe in sinter increased by 1.16 percent,drum strength increased by 0.57 percent,and sintering solid fuel consumption decreased by 1.46 kg/t.
