descend(When the burden materials and coke that are charged into the top of the blast furnace descend through the stack, they are preheated by the hot gases ascending from the tuyere. 当装人高炉炉顶的炉料和焦炭下降通过高炉炉身时，它们被来自风口上升的炽热煤气预热。)
stress-relief annealing(【技】在略低于再结晶温度下加热钢件，用于消除内应力的热处理。: Stress-relief annealing is the simplest heat treatment and is accomplished merely by heating metal to 649 - 732°C followed by air or furnace cooling. 去应力退火是一种最简单的热处理方式，只要将金属加热到649 -732°C, 随后空冷或炉冷，去应力退火即告完成。)
desulfurize(Calcium is highly reactive and it could deoxidize, desulfurize, modify oxide inclusions or modify sulfide inclusions. 钙具有较高的反应性，可用于脱氧、脱硫，对氧化物夹杂或硫化物夹杂进行改性处理。)
dephosphorization(【技】降低钢水或铁液中磷含量的过程。对于绝大多数钢种，磷是有害元素，应严格加以控制。脱磷反应是炼钢和铁水预处理的基本反应之一，是提高钢水质量的重要措施。: The static steelmaking model also computes slag basicities (nonnally in the range of two to five) for effective dephosphorization and desulfurization. 静态炼钢模型还能计算出炉渣碱度(正常值为2~5),以便有效地进行脱磷和脱硫。)
removal of inclusions(The inclusion removal steps are as follows: 1. Elimination of the sources of the inclusion generation; 2. transport of the inclusions to a steel/slag interface; 3. Separation of the inclusions at the interface; 4. Removal of the inclusions from the interface. 清除夹杂物的步骤如下：①清除产生夹杂物的来源；②将夹杂物移送至钢/渣界面；③在钢/渣界面处将夹杂物分离；④将夹杂物从钢/渣界面处清除。)
removal efficiency of nonmetallic inclusions(From the data in Table 6, it can be seen that both the amount of steel melt filtered and the removal efficiency of non-metallic inclusions are satisfactory. 由表 6 给出的数据可以看出，无论是过滤的钢水数量还是非金属夹杂物去除效率都令人满意。)
