oxygen enriched blast中文什么意思

例句与用法

1. Abstract : according to material and local heat balance in the blast furnace , refering to the result of oxygen enriched blast and coal injection into blast furnace and use of metallized burden , the influence of burden metallization degree on oxygen enriched - coal injection rate 、 coke rate and productivity is calculated
   文摘:根据高炉物料平衡和区域热平衡理论，参照高炉富氧喷煤和使用金属化炉料的冶炼结果，计算了炉料金属化率对富氧喷煤率、焦比和产量的影响。
2. It shows that with a metallization degree of burden more than 40 per cent , blast furnace can t be operated with oxygen enriched blast . combining lower burden metallization degree with oxygen enriched blast and coal injection , higher coal injection rate and higher productivity can be obtained . by use of higher burden metallization degree lower coke rate can be obtained than oxygen enriched blast and coal injection
   结果表明：炉料金属化率达到40后，高炉不能富氧操作；较低的炉料金属化率与富氧喷煤相结合，能够获得更大的喷煤比和更高的产量；使用金属化率较高的炉料，能够比富氧喷煤达到更低的焦比。
