A continuous casting and rolling method for non-ferrous metal alloys. The process of rolling molten metal into thin slabs through the gaps of a pair of horizontally arranged rollers. This method was jointly developed by two companies, Hunter and Douglas, in the United States in 1951.
The structure of the machining castings and rolling mill is shown in the figure. It has two horizontally installed pouring rolls, one to store molten metal ladle, and one vertically installed liquid metal nozzle between the horizontal rolls, as well as a set of slab coiling device.
During casting and rolling, the metal melt is sprayed through a nozzle under static pressure into the gap of the rotating down pouring roller at a certain speed. After passing through the gap, it rapidly cools and solidifies and crystallizes. As it is continuously rolled out of the gap, it is coiled into a strip. The Hunter sus investment casting and rolling method can produce various specifications of aluminum billets.
According to reports, it is possible to produce cast rolled slabs with a minimum thickness of 1.0mm and a maximum plate width of 2184mm.
Compared with the ordinary continuous casting method, the Hunter casting and rolling method significantly improves the grain size of the slab, the mechanical and forming properties of the alloy are significantly improved, and the surface quality of the casting and rolling billet is also good. Therefore, this type of cast rolled slab is highly welcomed by foil production plants.
