long product(① It is a simple matter to differentiate between flat products, which are derived from slabs, and long products, which are derived from blooms and billets. 很容易区分扁平材和长材，因为扁平材是由轧制板坯获得，而长材是由轧制方坯获得。② A width-to-thickness aspect ratio of 2.5 to 1.0 could be taken as the division between flat and long products. 宽厚比为 2.5:1.0 可以作为扁平材和长材的分界线。)
steel rod(After annealing, cooling, and removal of scale, the steel rod is pointed at one end and then inserted through a hole in the die slightly smaller than the size of the rod. 钢盘条经退火、冷却和清除氧化皮后，将其一端锤尖，插人比盘条直径稍小的拉模孔中。)
