Abstract

The invention provides a three-section type aluminum profile quenching and cooling device and method. Three sections are combined, the first section is cooled in a strong air and water mist manner, the second section is cooled in a strong water mist manner, and the third section is cooled in a strong air manner. In nozzles in different positions in each section, the flow of air and the flow of water can be proportionally adjusted; the different air cooling and water cooling nozzles are arranged on the periphery of the section of an aluminum profile, the flow of each nozzle can be adjusted in a stepless manner to be suitable for quenching and cooling of aluminum alloy profiles with different sections and of different specifications and materials, and the air volume and the water flow of each nozzle on each section can be adjusted according to the practical condition. By the adoption of the three-section type aluminum profile quenching and cooling device, the cooling speed range large enough can be provided, the cooling speed of different positions of each aluminum profile can be accurately controlled, and different quenching and cooling processes of the aluminum profiles with different sections and of different specifications and materials can be achieved.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, is a new device for on-line quenching and cooling in the rear finishing system of an aluminum extrusion machine, and mainly relates to a three-stage on-line quenching and cooling device suitable for the extrusion production process of aluminum profiles. Background technique [0002] In the extrusion process of aluminum profiles, after the aluminum profiles are hot-extruded by the extrusion machine, they need to be quenched and cooled, so that the comprehensive technical performance indicators such as hardness and strength can meet the quality requirements of aluminum profile products. [0003] Among the common on-line quenching methods for aluminum profiles, air-cooling quenching, gas mist quenching and water mist quenching have low cooling speeds, which are difficult to meet the quenching strength requirements, and the cooling speed is difficult to control; although the water immersion quen...
