multipoint bending and unbending(The continuous slab caster with an annual capacity of 900, 000 tonnes is equipped with an automated variable width mold, large capacity tundish, multipoint bending and unbending devices and air mist cooling system. 这台年生产能力 90 万 t 的板坯连铸机装备有自动调宽结晶器、大容量中间包、多点顶弯与矫直设备以及气雾冷却系统。)
end-point control system of basic oxygen furnace(① We have developed the endpoint control system of basic oxygen furnace (BOF) and applied the system to automatic oxygen blowing control. 我们已经开发出氧气顶吹转炉终点控制系统，并将该系统运用到吹氧自动控制。② We can thus get the target temperature at end of oxygen blowing by using the endpoint control system of basic oxygen furnace (BOF). 通过使用氧气顶吹转炉终点控制系统，我们就可以得到停吹氧目标温度。)
AOD process advantages(AOD 法的优势【技】(1)生产效率高。一座电弧炉和一座氩氧精炼炉双联操作的产量相当于两座电弧炉的生产能力。(2)基建投资低，维护方便，操作简单。(3)生产成本低。可以利用返回钢、高碳铬铁等廉价原料顺利生产超低碳不锈钢。(4)钢的质量得以提高，明显优于传统的电弧炉钢)
particle image velocimeter(Particle image velocimeter (PIV) is a laser-based technology which, when combined with a high-speed camera, can be used to measure in real time the velocity of the water, that of the gas bubbles it may contain as well as their velocity vectors in water model of mold, which can be used to determine the water and gas flow patterns. 质点成像测速仪以激光技术为基础，与高速摄像机相结合，可用于实时测量结晶器水模中的水流速度、水中气泡速度以及它们的速度矢量，用以确定水流和气流的运动模式。)
