Technical Information
| 1 | LF6 aluminum alloy ingot is pretreated, and the pretreated ingot is homogenized and annealed at 450-480°C for 12h, and then placed in the extrusion barrel of the extruder. |
| 2 | Heat the product mold in the extrusion cylinder to 450-500°C, control the temperature of LF6 aluminum alloy ingot to 380-410°C, control the temperature of extruder outlet to 300-340°C, and clamp the working table with the product mold and the extrusion cylinder. |
| 3 | The extrusion barrel in the extruder runs toward the product mold at an extrusion speed of 2.5-3.5m/min, extrudes the LF6 aluminum alloy ingot, and the LF6 aluminum alloy ingot is extruded out of the die hole of the product mold to obtain the LF6 aluminum alloy reinforced plate slat, in which the LF6 aluminum alloy ingot is heated by a segmented gradient heating method, and the head of the extruding barrel is heated at a temperature of 440-460°C, and the middle of the heating The head of the extrusion cylinder is heated at a temperature of 440-460°C, the middle is heated at a temperature of 440-460°C, and the tail is heated at a temperature of 370-390°C. |
| 4 | The LF6 aluminum alloy with ribbed plate slat made in step C is quenched, and the quenching method is the synchronous method of air cooling and atomized cooling, and the temperature of the quenched LF6 aluminum alloy with ribbed plate slat is 120-130°C. |
| 5 | The quenched LF6 aluminum alloy reinforced plate slat is subjected to aging heat treatment, the aging temperature is 180-220°C, and the aging time is 3-8h. |
| 6 | Welding for large width LF6 aluminum alloy strip plate. |
