Production line for producing magnesium alloy products by temperature-control continuous rolling

Abstract

The invention discloses a production line for producing magnesium alloy products by temperature-control continuous rolling. The production line comprises a multi-frame temperature control continuous rolling machine, roller surface heating devices, heat conveying rollers, plate strip heating devices and a control unit, wherein the multi-frame temperature control continuous rolling machine is provided with multiple frames; rollers are correspondingly arranged on all the frames; the roller surface heating devices are arranged corresponding to all the rollers for heating all the rollers; the heatconveying rollers are arranged at the upstream parts of the frames corresponding to the frames; the plate strip heating devices are arranged at the upstream parts of the frames corresponding to the frames; and the control unit is connected with the roller surface heating devices, the heat conveying rollers and the plate strip heating devices for controlling the heating process. The production lineproduce rolled magnesium alloy products by adopting a whole-process temperature control continuous rolling mode, in particular thin magnesium plates, pieces or magnesium rolls; the continuous precisetemperature control rolling is performed aiming at plastic deformation characteristics of magnesium alloy materials in the whole production process; and through whole-process temperature control continuous rolling, the mode of repeated low-temperature heat feeding of the magnesium alloy materials in traditional intermittent multi-pass rolling is prevented, so that the energy consumption is saved.

Description

technical field [0001] The invention relates to a production line, in particular to a production line for producing magnesium alloy products. Background technique [0002] With the development of global urbanization and industrialization, the number of vehicles and aircrafts has increased rapidly. However, this brings great challenges of energy consumption and low-carbon development. Lightweight is an effective means to reduce vehicle energy consumption and reduce carbon emissions. Magnesium alloy is a light metal structural material, and the density of pure magnesium is 1.74g / cm 3 , which is only 1 / 4 of steel and 2 / 3 of aluminum, so the use of magnesium alloy to make parts has a significant weight reduction effect and can significantly reduce energy consumption. [0003] In recent years, the demand for magnesium alloy sheets has been increasing in the fields of aerospace, automobiles and rail transit. Magnesium alloys have good hot extrusion plasticity, and extrusion is...

Problems solved by technology

In the technical solution disclosed in this patent document, the reciprocating tension-free rolling method of single-stand multi-pass repeated biting has the following disadvantages: ① The repeated biting method will inevitably lead to low dimensional accuracy in the thickness direction, and the plate ② The result of tension-free rolling is poor plate shape, uneven, easy warping, and waves; The required production line is very long; ④ Repeated biting, frequent start and stop of the rolling mill leads to low production efficiency

However, how to generate metal coils, especially magnesium coils that need to be coiled within a certain temperature range, is not involved in the technical solution disclosed in this patent document.
