rod of steel(A rod of steel 30mm in diameter - just over an inch - can support a load of over 25 tonnes without fracture. 一根直径 30mm 仅 1in 多的钢棒，可以承受 25t 以上的负荷而不破裂。)
billet return electrode(直流电弧炉的一种炉底电极: The billet return electrode configuration employs from one to four large steel billets (on the order of 10 ~ 15cm diameter but can be as large as 25cm diameter) depending on the size of direct current electric arc furnace. 根据直流电弧炉的吨位，钢棒式电极装置可以配置 1 至4根大型钢棒(直径约为10 ~ 15cm, 有时直径可达 25cm)。)
billet electrode(直流电弧炉的一种炉底电极: Several different designs exist for the bottom return electrode of a direct current electric arc furnace including metal pin return electrodes, billet electrode, metal fin electrodes, and conductive bottom refractory. 直流电弧炉炉底回路电极有几种不同的结构，其中包括金属触针式回路电极、钢棒式电极、金属叶片式电极以及导电耐火材料炉底。)
solid rod of hot steel(A solid rod of hot steel is spun between two mutually inclined rolls which rotate in the same direction, so that the rod is pulled forward between them, and passes over the mandrel. 一根高温实心钢棒在两个相互倾斜、旋转方向相同的轧辊之间旋转，钢棒在两辊之间受拉向前，沿芯棒周围通过。)
