1980年以来,我国引进并试制了一批小方坯连铸机,这对我国中小型钢铁厂的技术改造起了推动作用,因为要发展这一技术,不仅要求革新浇铸工艺,同时,对炼钢、耐火材料等领域的技术发展提出了更高的要求。 R5.25米小方坯连铸机采用多流多机配置,每流均有独立的传动系统,布置总图见图1。其主要性能参数为: 弧形半径(R) 5.25m 结晶器断面范围 70×70～150×150mm 结晶器振动振幅 ±6mm 结晶器振动频率 75～240次/min 拉坯速度 0.57～5.7m/min
Since 1980, a batch of billet caster was introduced and trial-produced in our country, which played a role in promoting the technological transformation of the small and medium-sized steel mills in our country. To develop this technology, we not only need to innovate the casting process, Steel, refractories and other areas of technological development put forward higher requirements. R5.25 m billet caster adopts multi-stream multi-machine configuration, each stream has an independent transmission system, the layout of the general plan shown in Figure 1. The main performance parameters: radius of curvature (R) 5.25m crystallizer section range 70 × 70 ~ 150 × 150mm mold vibration amplitude ± 6mm mold vibration frequency 75 ~ 240 times / min casting speed 0.57 ~ 5.7m / min
