Focusing on the limitations of the traditional Continuous Casting-Direct Hot Charge Rolling (CC-DHCR) planning and scheduling methods that rarely consider dynamic scheduling problems, a new method is put forward. The key idea is to make out clusters and integrated plans in the planning layer, and then to adjust the rolling sequences according to the slab cluster-based strategy in the dynamic scheduling layer. Results of the test with data from practical production process show that the method can effectively solve the CC-DHCR planning and scheduling problem and increase the DHCR ratio.

Liquidus Temperatures

Several Mg alloys were processed to achieve the thixotropic microstructure of non-dendritic, globular primary grains for semisolid forming using a novel method that does not require stirring. The alloys were poured at their liquidus temperatures or about ten degrees below the liquidus temperatures using either batch or semi-continuous casting. Although the compositions of the alloys had considerable effects on details of the resulting microstructure, generally fine, equiaxed primary grains were obtained by controlling the resting time, casting speed and cooling rate. The lower casting temperatures and addition of calcium were effective in preventing burning of Mg without using a protective atmosphere. This new method has great potential for industry applications.
