還原鐵粉
是利用固體或氣體還原劑還原鐵的氧化物來制取海綿狀的鐵。還原過程中分為一次還原和二次還原。一次還原**是固體碳還原制取海綿鐵,一次還原主要流程是:鐵精礦→烘干→磁選→粉碎→篩分→裝罐→進入一次還原爐→海綿鐵。二次精還原流程:海綿鐵→清刷→破碎→磁選→二次還原爐→粉塊→解碎→磁選→篩分→分級→混料→包裝→成品。用還原法所生產的**鐵粉,各項參數達標,Fe≥98%,C≤0.01%,磷和硫都小于0.03%,氫損為0.1~0.2%。
我公司是采用軋鋼**鐵鱗經二次氫氣還原制成海綿狀**鐵粉,技術指標達到**標準規定。具有以下特點:
高純度、低夾雜、一致性好、細粉含量高、壓縮性和成型性好。
在摩擦行業中:
一次還原鐵粉主要用于半金屬摩擦材料中和鋼釬維一起構成其中的金屬部分;
二次還原鐵粉可使摩擦系數平穩,相對于一次還原鐵粉,它是少孔結構有利于半金屬摩擦材料代鋼纖維主要組成部分,減少纖維用量。提高摩擦材料的制品性能。
Reduced iron powder
Through reductant iron utilization of solid or gas to produce sponge iron oxide. The first reduction and the second reduction take the part of the reduction process. The reduction of producing sponge iron is solid carbon reduction, its main process is: the iron concentrate, drying, magnetic separation, crushing, sieving, canning, into a reduction furnace, sponge iron. The second reduction process: sponge iron, cleaning, crushing, magnetic separation, the two reduction furnace, powder and solution of fragmentation, separation, screening, classification, mixing, packaging and finished product. Using high quality iron powder reduction method in the production of various parameters, standard, Fe ≥ 98%,C≤ 0.01%, phosphorus and sulfur both less than 0.03%, hydrogen loss ranged from 0.1 to 0.2%.
Our company is using high quality steel iron scale through two hydrogen reduction into cavernous quality iron powder, technical indicators have reached the national standard. characteristics following :
High purity, low inclusion, good consistency, high content of fine powder, compression and molding.
In friction industry:
The reduced iron powder is mainly used in semi-metallic friction material and steel fiber together constitute one of the metal parts;
The second reduced iron powder can make smooth friction coefficient, relative to a reduced iron powder, it is less porous structure facilitates the semi-metallic friction material steel fiber main part, improve product performance of friction materials.
