为促使高炉法钙镁磷肥企业在提高产量、降低消耗的基础上提高企业经济效益,云南沾益磷肥厂在2#高炉上用纯氧提高鼓风空气中氧含量1%～2%进行工业性生产试验。试验证实了适当提高氧含量鼓风是安全可靠的,提高氧含量鼓风尽管技术很成熟,但由于氧含量提高过少,影响钙镁磷肥高炉技经指标因素较多,试验未取得理想效果。应进一步制定提高鼓风中氧含量在10%～30%的试验方案,继续试验,开发这一工业应用技术。
To promote the blast furnace of calcium magnesium phosphate fertilizer enterprises to improve production and reduce consumption based on improving economic efficiency, Yunnan Zhanyi phosphate fertilizer plant in 2 # blast furnace with pure oxygen to improve the blast air oxygen content of 1% to 2% for industrial Production test. Test confirmed that the appropriate increase in oxygen content Blasting is safe and reliable, to improve the oxygen content Although the technology is very mature, blast furnace, but due to the increase of oxygen content is too small, the impact of calcium magnesium phosphate fertilizer blast furnace technology by many indicators, the test did not achieve the desired results. Should further develop the blast in the oxygen content of 10% to 30% of the pilot program to continue testing and development of this industrial application of technology.
