Description
Technical Field
The invention relates to a magnesium alloy production process, in particular to a production process of a magnesium alloy extrusion material.
Background
The extruded material of the magnesium-aluminum alloy in the light alloy has higher strength, plasticity, corrosion resistance and other comprehensive properties than an as-cast state, can realize one-time extrusion molding by extrusion processing of the light alloy, has high production efficiency and high product flexibility, can produce products with complex cross section shapes, and has obvious light weight effect, so the extruded material of the magnesium-aluminum alloy in the light alloy is paid keen attention in the fields of aerospace, automobiles, rail transit and the like.
Further, the magnesium alloy has a low density (density of 1.8 g/cm)3) High specific strength and specific rigidity and certain excellent physical properties (such as heat conducting performance, electromagnetic shielding performance, damping performance and response characteristic to sound high-frequency sound range), so that the composite material has good application prospect in the fields of transportation industry such as automobiles and rail transit, household appliance and electronic industry and the like.
However, higher requirements are also placed on the mechanical properties, straightness of the extruded material and production efficiency of the extruded material.
In the prior art, the preparation process of the magnesium alloy extruded material comprises the following steps: the hot extrusion machine is responsible for extrusion, and then, the haulage line is responsible for drawing and the scale cutting the extruded extrusion material, and the straightening is carried to the straightener to the extrusion material at last.
In the process, the straightening machine usually adopts a stretching straightening machine, and the principle is that longitudinal fibers of a metal workpiece are inevitably uneven in length when the metal workpiece is not straight, and the uneven-length fibers are inevitably recovered to a stable state by basically equal elastic recovery when external force is removed after the metal workpiece is subjected to plastic stretching to reach equal length, so that the straightening purpose is achieved.
However, because the magnesium alloy material has insufficient plasticity at room temperature and low formability, the magnesium alloy extruded material cannot be straightened and straightened at room temperature, and the magnesium alloy material must be heated to a certain temperature before being straightened, the straightening device suitable for the magnesium alloy extruded material must be composed of a heating device and a straightening machine together, so that the production line of the magnesium alloy hot extruded finished product is long, and the production efficiency is low.
In addition, in the single tractor generally adopted in the prior art, after the extruded material reaches a certain length, the extruder needs to be stopped or limited in speed to complete cutting and return of the tractor head, which causes that the production line cannot produce continuously, not only the production efficiency is affected, but also the shutdown or speed reduction of the main machine causes intermittent changes of the temperature field and the pressure field of the extruded material in the die, and causes uneven properties of the extruded material.
The Chinese patent document with the publication number of CN102266881A and the publication number of 2011, 12, 7 and the name of 'the stretching straightening device for the online heating and straightening process of the magnesium alloy extruded material' discloses a stretching straightening device for the online heating and straightening process of the magnesium alloy extruded material, and the device is provided with a heating device below a track for supporting the extruded material by a straightening machine, so that the phenomenon of bending caused by thermal stress is avoided due to the support of the track in the process of heating the extruded material.
Chinese patent publication No. CN103302130A, published as 2013, 9, and 18, entitled "a high-performance magnesium alloy profile with complex cross section" discloses a high-performance magnesium alloy profile with complex cross section. In the technical scheme disclosed in the patent document, the preparation process comprises the following steps: the method comprises the steps of heating a casting blank → heating a die → heating an extrusion cylinder → extruding → drawing by a tractor → cutting and pressing strip → tension straightening → sawing → artificial straightening, and the high-speed extrusion, straightness and low residual stress state of the magnesium alloy extrusion material are ensured because the magnesium alloy blank is heated by a three-stage temperature-gradient heating process without temperature compensation and vibration stress removal.
Chinese patent publication No. CN104060202A, published as 24/9/2014, entitled "an online temperature correction device for magnesium alloy extruded material", discloses an online temperature correction device for magnesium alloy extruded material. The device utilizes a plurality of running roller roll-in straightener to realize can carrying out the roll-in straightening of magnesium alloy extruded material in extrusion mouth department, and its process that saves than conventional is: the reheating before straightening does not need to be off-line, and the shortening of the flow is very limited.
In conclusion, the production line of the magnesium alloy extruded material in the prior art is too long, and a traction machine and a straightening machine need to be arranged independently, which is not beneficial to improving the production efficiency and saving the production cost. Therefore, a production method is expected to be obtained, on one hand, the continuous production of the magnesium alloy extruded material product can be ensured to be realized on a shorter production line, so that the process steps are saved, the production efficiency is improved, the cost of the magnesium extrusion process is reduced, and on the other hand, the high precision of the straightness of the produced magnesium alloy extruded material is favorably improved.
