dam and weir flow design(The three tundish designs chosen: (a) dam and weir flow design, (b) weir/baffle flow design and (c) single baffle flow design. 人选的三种中间包设计方案：(a) 坝/堰流动设计； (b) 堰/缓冲板流动设计； (c) 单缓冲板流动设计。)
dam and weir(【技】中间包内导流装置。可改善中间包内钢水流动轨迹、防止中间包内钢水卷渣、减少死区体积、增加平均停留时间、促使夹杂物上浮、提高钢水纯净度。: The use of dams and weirs is intended to reduce short circuiting flow and provide full use of the tundish volume. 使用坝堰的目的是减少短路流、充分利用中间包容积。)
breast wall(热风炉的: A sturdy brick breast wall separates the combustion chamber from the balance of the stove, which is filled with checker brick. 一道坚固的砖砌挡火墙将燃烧室和砌满格子砖的热风炉其余部分隔离开。)
radiation from arc to sidewalls(At the start of meltdown in electric arc furnace the radiation from the arc to the sidewalls is negligible because the electrodes are surrounded by the scrap. 电弧炉开始熔化时，电极被废钢包围，因而电弧对炉墙的辐射作用可以忽略不计。)
wall thickness at taphole(Hearth diameter refers to the diameter of the circle determined by the inside face of the refractory lining of the hearth, excluding any increase in the wall thickness at the tapholes. 炉缸直径指的是炉缸耐火衬内面圆的直径，铁口处炉墙厚度的增加部分不含其内。)
