Embodiment Construction

[0014] As shown in Figure 1, Figure 2, and Figure 3, the online heat preservation and quenching device consists of a support 1, a graphite plate 2, a cylinder 3, a water tank 4, a water spray pipe 5, a heating and heat preservation device 6, a temperature measuring element 7, and a lifting device 8 and other parts; the bracket 1 is located in the middle of the water tank 4 and is in the shape of a strip. The upper side of the bracket 1 is equipped with a plurality of rollers 3, and the rollers 3 are arranged at equal intervals. There are several graphite plates 2 between each two rollers 3. The bracket 1, the roller 3 and the graphite plate 2 form a slide-out platform structure, on which profile products can slide; the heating and heat preservation device 6 is in the shape of a pipe, buckled upside down on the slide-out platform, and the inner wall is equipped with an electric heating device 10; the water tank 4 is arranged on Sliding out of the platform periphery, water spray ...

Abstract

An on-line thermal-insulating heat-treating quenching apparatus for high or ultra-high strength aluminum-alloy and its quenching process are disclosed. A rectangular stand is arranged in middle of catch pan, drum, graphite plate and under-frame form into guiding bench structure, electric heater is installed on its internal wall, catch pan is placed outside of guiding bench, spray pipe is arranged on both sides and cooling liquid is spurted from it. The process is carried out by discharging aluminum-alloy thermal extrusion product, entering it into thermal insulator, on-line adjusting temperature, keeping temperature, moving thermal insulator, on-line quenching, stretching and aligning. It's cheap and simple, has less consumption and shorter production period.

Description

technical field [0001] The invention relates to a quenching device and a quenching process using the device, in particular to an online heat preservation quenching device and a quenching process for heat treatment of high-strength and ultra-high-strength aluminum alloys. Background technique [0002] Most of the 2XXX series, 5XXX series, 6XXX series and 7XXX series of industrially deformed aluminum alloys are high-strength or ultra-high-strength aluminum alloys. As far as the existing quenching technology is concerned, after this type of aluminum alloy is hot-extruded, it needs to be heated and kept in a special quenching furnace (usually a vertical quenching furnace), and then cooled in a sufficiently deep cooling liquid (usually water). Quenching in the well, the quenching process is: aluminum alloy hot extrusion product forming→cooling the hot extrusion product→drilling at the end of the hot extrusion product, threading iron wire→hanging the hot extrusion product on the h...
