Aluminum alloy profile online heat treatment technical parameters
ã€China Aluminum Network】 Aluminum extrusions go through three stages, namely quenching, quenching and cooling to ambient temperature after quenching. In order to prevent undesired precipitation of the second phase, the profile is about to enter the cooling device (quenching) The temperature of the zone must be above the solvus temperature. The cooling rate and the cooling contact time of the cooling device should be sufficient to obtain the required supersaturated solid solution content, so that the final product performance meets the use requirements. The distance from the extrusion die to the quenching zone should be as small as possible, ie the quenching transfer time should be as short as possible. Extrusion in-line quenching alloys can achieve the following properties: (1) Has tensile strength properties that are consistent with structural applications; (2) The quenching sensitivity is low, and forced cooling can be applied to various products with different sections without water quenching; (3) The temperature range between the alloy solid solubility line and the solidus line is wide, and it is easy to control the desired solution temperature range of the product outlet temperature; (4) The material has sufficient toughness when air-cooled; (5) In the solution temperature, the deformation resistance is low, the deformation energy and overall temperature rise are reduced as much as possible, and a higher allowable extrusion speed is obtained; Cleaning Brush,Electric Cleaning Brush,Car Cleaning Brush,Cleaning Brush Automatic Laizhou Chenke trading Co., Ltd. , https://www.chenkegroup.com
