Embodiment 1
[0061] In the first embodiment of the present invention, a continuous casting and rolling process is used to prepare a SiCp / Al composite profile with a volume fraction of 10% and a substrate of 6061 aluminum alloy, such as Figure 4 As shown, the section of the profile is in the shape of a "dog bone", and the specific steps are as follows:
[0062] S1, such as image 3 As shown, first select the "dog-bone"-shaped roll sleeve to assemble it into a cast roll system, and adjust the roll gap to 3mm;
[0063] S2, put the base aluminum alloy raw material into the ladle, pass argon gas into the composite slurry preparation device from the protective gas conduit 16, set the heating temperature of the heating furnace to 700°C, heat the aluminum alloy in the ladle to a molten state, and the metal Melt temperature is monitored by thermocouple test;
[0064] S3, use the blades of the electric stirrer to stir the metal melt quickly, after forming a vortex in the center of the ladle, add ...
Embodiment 2
[0068] The second embodiment of the present invention is that the single-quality 6061 aluminum alloy is produced by continuous casting and rolling, such as Figure 6 For the variable cross-section profile shown, the specific steps are as follows:
[0069] S1, such as Figure 5 As shown in the figure, first select the roll sleeve with variable section in the shape of "I" to form the casting roll system, and adjust the roll gap of the flat part to 5mm;
[0070] S2, put 6 aluminum alloy raw materials into the ladle, set the heating temperature of the heating furnace to 680°C, heat the aluminum alloy in the ladle to a molten state, and the temperature of the molten metal is monitored by a thermocouple test;
[0071] S3, adjust the centering roll gap of the distribution flow assembly, and maintain its height at about 30mm, set the casting-rolling machine speed at 2m / min, and start the casting-rolling machine;
[0072] S4, open the sliding nozzle, adjust the outflow speed, pour th...
Embodiment 3
[0074] The third embodiment of the present invention utilizes the continuous casting and rolling method to produce periodic variable-thickness cross-section profiles with 304 stainless steel as material, schematic diagram Figure 8 As shown, the specific steps are as follows:
[0075] S1, such as Figure 7 As shown, firstly select roll sleeves with periodic rectangular section to form the casting roll system, and adjust the roll gap to 5mm;
[0076] S2, put the 304 stainless steel raw material into the ladle, set the heating temperature of the heating furnace to 1480°C, heat the 304 stainless steel material in the ladle to a molten state, and the temperature of the molten metal is monitored by a thermocouple test;
[0077] S3, adjust the centering roll gap of the distribution flow assembly, and maintain its height at about 30mm, set the casting-rolling machine speed at 1.5m / min, and start the casting-rolling machine;
[0078] S4, open the sliding nozzle, adjust the flow rate...
