由中国重型机械研究院自主创新设计的420 mm×2 700 mm直弧形板坯连铸机在南阳汉冶特钢有限公司成功投产,该连铸机采用了诸多关键技术,并针对特厚大断面及品种钢的生产规范了主要控制要点。该连铸机已成功浇铸超厚大断面铸坯,打破了我国由连铸坯直接轧制特厚、特宽钢板的瓶颈,标志着我国连铸工艺技术及装备水平迈上新台阶。
The 420 mm × 2 700 mm straight arc slab caster independently developed by China National Heavy Machinery Research Institute was successfully put into operation at Nanyang Hanye Special Steel Co., Ltd. The continuous casting machine adopts many key technologies and is designed for large thick Section and varieties of steel production specifications of the main control points. The continuous casting machine has successfully cast super-thick large-area slab, breaking the bottleneck of direct rolling super-thick and extra-wide steel plate from continuous casting slab in our country, marking a new stage of continuous casting technology and equipment in our country.
