Heat treatment device and heat treatment process for ultra-long aluminum extrusion

Abstract

The invention discloses a thermal treatment device and a thermal treatment technology of an ultra-long aluminum extrusion, and belongs to the technical field of material processing. The thermal treatment device comprises a heating furnace, a quenching water well, a feeding and discharge rail, a feeding trolley, a discharge trolley, a lifting device and a material basket, wherein a furnace body isan ultra-long horizontal furnace composed of a plurality of regions of which the temperature is independently controlled; and a product is horizontally stacked in the material basket, and enters the furnace body or the quenching water well through the feeding trolley, the discharge trolley and the lifting device to be subjected to thermal treatment. According to the thermal treatment device and the thermal treatment technology, horizontal furnace horizontal heating and inclined descend soaking quenching technologies are adopted to replace traditional vertical quenching and roller hearth type quenching technologies, the quenching cooling speed is high and uniform, quenching deformation of the product is low, surface quality is good, and performance is uniform; solid-solution quenching, annealing and ageing functions can be achieved, production scheduling is flexible, length of a biggest product of thermal treatment is large, charge batch is large, production efficiency and heat utilization rate are high, and operation is safe and reliable; and besides, deep well, heat-resistant roller, spraying devices, and the like are not required, basic requirements on equipment are low, and investment is low.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a heat treatment device and a heat treatment process for an ultra-long aluminum extruded material. Background technique [0002] At present, the offline solution quenching of aluminum alloy extruded materials mainly adopts vertical quenching technology, that is, vertical furnace heating + immersion quenching, and a small part of it adopts roller hearth quenching technology, that is, horizontal roller hearth furnace heating + spraying. The quenching method is used, while the aging and annealing need to be carried out in another aging furnace or aging and annealing furnace. [0003] The traditional vertical quenching technology requires the product to be erected and the lifting height is large, resulting in a maximum lifting weight of only 2-5 tons, and its production capacity is greatly limited; it is necessary to dig a deep well slightly larger than the pr...
