EBT electric arc furnace(The company supplied the complete electric steelmaking plant with an annual capacity of 600, 000 tonnes comprising a 150t EBT electric arc furnace with slag-free bottom tapping, a ladle heating furnace, a vacuum degasser for secondary metallurgy and four-strand continuous caster for rounds with diameters ranging from 210 to 310mm. 该公司提供了一套年生产能力 60 万 t 的电炉炼钢设备,其中包括一座具有无渣炉底出钢功能的 150t 偏心炉底出钢电弧炉、一座钢包加热炉、一台二次冶金用真空脱气装置以及一台用于浇铸直径210 ~ 310mm 圆坯的四流连铸机。)
covering tuyere during splash(The problem of covering the tuyere during splash has been solved with increased gas pressures and flows. 溅渣时炉渣覆盖炉底喷嘴的问题已通过提高喷气压力和流量得以解决。)
furnace with rotating hearth(Each tube billet is check-weighed and passed by a conveyer to a large furnace with a rotating hearth which passes through several temperature zones in the furnace so that finally the steel has been heated to 1250°C. 对每一管坯进行称量校核后,通过运输机将管坯运送到一个大型转底炉中,炉底旋转经过炉子的几个温度区,最终将钢管坯加热到 1250°C。)
Bessemer process(The L-D process combines the low capital cost and high speed of operation of the Bessemer process with the high product quality of the open-hearth. L-D 炼钢法将贝塞麦炼钢法的投资费用低、生产速度快和平炉炼钢的产品质量高等优点集于一身。)
basal crack(Basal crack refers to a crack in the bottom end of an ingot caused by the lack of free contraction during freezing. 锭底裂纹指的是钢锭凝固时,因自由收缩受限制引发的钢锭底部裂纹。)
BOF combined blowing practice(The concentration product 【0】 【 C 】 in OBM steelmaking is lower than in the BOF combined blowing practice, particularly at low carbon levels. OBM 炼钢法的【0】 【C】 浓度积小于)
