| Popis: | Integrated casting and rolling in a series production line is well established for the non-ferrous metals through the use of twin-belt casting technology. However, this twin-belt casting with high mass flow is not yet commercialized in the continuous production of steel alloys. A novel steel casting for the in-line rolling (named LUUP method) is presented and one main focus of this work is to design a casting machine: twin-belt caster. Influence of mass flow rate and dimensional ratio on the solidification, compensation, and total process length is addressed. A gap-dependent belt and dam block side heat transfer is modeled. The admissible casting speed due to the limitations of caster length and shell strength is addressed. The total process length only depends on the mass flow rate. A 2D traveling slice numerical model is presented with realistic boundary conditions for the entire process starting from the meniscus to roll mill entry. |
