针对组合板式结晶器对包钢重轨坯造成的铸坯缺陷,开发研制了280mm×380mm断面的管式高效结晶器并投入使用。目前它是国内最大断面的方坯管式结晶器。
Aimed at the slab defects caused by the combined slab mold on the heavy rail blanks of Baotou Steel, a tubular high efficiency crystallizer of 280 mm × 380 mm was developed and put into use. It is currently the largest section of the billet tube mold.
