燒結入爐比
英文
sinter consumption-
In recent years at iron - making plant of pangang, the coke ratio of pig iron has reduced evidently by insisting on “ burden preparation ” course, improving quality of sinter, raising wind temperature, increasing rich oxygen quantity and injecting abundant pulverized coal into bf. the solid fuel consumption of sinter has been decreased greatly through insisting on using high - quality calces, practising high feed sintering, actualizing many techniques in solving key problems. at the same time, the energy source base management has been strengthened, and energy - saving work has made great progress, profits generated by energy - saving have exceeded a hundred million yuan
近年煉鐵廠通過堅持「精料」方針，改善燒結礦質量，提高風溫，增大富氧，實施大噴煤，使入爐焦比有明顯下降；燒結堅持用好生石灰，推行厚料層燒結，實施多項技術攻關，固體燃耗大幅度下降；同時加強能源基礎管理，節能工作取得長足進步，節能創效益1億元以上。The influence of nano - al2o3 on the sintering and the properties of the si3n4 ceramics was researched in this paper. the samples with different amount of nano - al2o3 were obtained by using pressureless sintering at 1600, 1650, 1700 in the nitrogen atmosphere. the microstructure and the composition of the ceramics were determined by the means of x - ray, sem, micro - hardness meter etc. it is show that the sisty ceramics can be densified at 1650c to % percent of the theory density through the addition of nano - al2o3 ( the value could be 90 percent by other technique ). the crystalline growth of the cylindrical - si3n4 and the ratio of its longitude to its diameter are increased with the addition of nano - al2o3. a uniform microstructure and an fined crystal as well as more sialon phases can be obtained in the si3n4 ceramics through the addition of that
實驗結果表明：在碳管爐中、氮氣保護下進行燒結，添加劑為納米al _ 2o _ 3粉末時，由於納米粉末的高活性、高燒結驅動力，在1650就可使si _ 3n _ 4完全地燒結，並使其緻密度可達理論密度的96以上（比其它工藝高6左右） ；同時，納米al _ 2o _ 3地加入大大促進了長柱狀? si _ 3n _ 4的生長和發育及柱狀晶長徑比的提高，使微觀結構均勻、細化，形成了更多力學性能優異的固體? sialon相，減少了不利於陶瓷材料性能的晶間玻璃相，凈化了晶界。Additions of carbon for improved slag resistance. spinel formation improves hot strength, slag resistance and brick joint erosion. 3 repairing material for bof uses fused magnesia or sintered magnesia as the main raw material and after modifid pitch and special additives are added, it has the following characteristcs than other conventional converter pitch temperature, shorter sintering time, longer service life and less pollution. it is mainly used for repairing converter working face, also for tapping side, tapping hole and bottom
3 ，轉爐大面補料是採用電熔鎂砂或燒結鎂砂為主要原料，通過加入改性瀝青和特種添加劑使它和傳統瀝青補爐料相比具有高溫附著性好燒結時間短流動性好使用壽命長污染小等特點，主要用於修補轉爐迎鋼面通常稱「大面」也可以用於修補出鋼側，出鋼口及爐底等部位。Some tests for liangang sinter adding bos slag have be done in the laboratory and plant trial. the results show that in the range of bos slag percentage, from 0 % to 8 %, with the increase of bos slag percentage, the sinter speed has been lower, but the sinter strength and productivity of sinter product have been higher, the sinter productivity will be the maximum when bos slag percentage is 4 % ; the siner reducibility has been improved, the normal operation of bof will not be effected anymore because of the circulation of p form bos slag
對燒結礦配加轉爐鋼渣進行了實驗室研究和工業試驗，在鋼渣配比0 % 8 %的范圍內進行的研究表明：隨著鋼渣配比的增加，燒結速度稍有下降，燒結礦強度、燒結成品率均有所提高，利用系數在4 %左右時達到最大值；燒結礦還原性得到改善；鋼渣中帶入的p的循環富集不會影響煉鋼的現行操作。分享友人
