摘　　要：某新建165 mm×1 100 mm板坯连铸机,其稳定工作拉速为2.2 m/min。结晶器作为第一凝固区,直接决定了工作拉速、初生坯壳厚度和最终铸坯质量。以设计计算为依据,借鉴常规板坯结晶器的结构设计,从铜板水缝排布、宽窄面足辊支承和布置、夹紧装置预紧力设定、调宽调锥装置等方面分析及优化。采用强化弯月面冷却的水缝排布形式,宽面双排小辊径足辊,可实现刚性工作的碟簧预紧型窄面足辊,大预紧力的夹紧装置,合理连接形式及布置的结晶器调宽装置等技术,以确保该规格铸机高拉速和高品质的实现。A new 165 mm×1 100 mm slab caster,which has the stable casting speed is 2.2 m/min. As the first solidified area,mold directly determines the casting speed,the thickness of the initial shell and the final slab quality. In the paper,based on the calculation and referenced to conventional mold structural,water slot of copper plate,the support and arrangement of the foot roll,the preload setting of the clamping device,structural of the width adjusting device are analyzed and optimized.The reinforced cooling water slot arrangement around of meniscus,the double smaller diameter of width roller,narrow foot roller by disc spring preload,even bigger preload of the clamping device,more reasonable connection form of width adjusting device,are used to ensure the high casting speed and high quality.
