The invention discloses a magnesium-alloy-plate rolling uncoiler unit. The uncoiler unit comprises a collapsible drum and an uncoiling holding furnace. The uncoiling holding furnace comprises a furnace body, a furnace cover and a railcar. The railcar comprises two straight guide rails arranged in parallel, a driving car cooperated with the guide rails, and a control device used for controlling the reciprocating stroke of the driving car. The furnace cover is vertically arranged corresponding to the ground. The collapsible drum passes through the furnace cover and rotatablely cooperated with the furnace cover. The furnace body is fixed to the driving car. According to the magnesium-alloy-plate rolling uncoiler unit, the holding furnace and an uncoiler are integrated, and after magnesium alloy plates are installed on the collapsible drum, the magnesium alloy plates can be heated to a required temperature of a rolling technology through the holding furnace, thus improving plasticity of the magnesium alloy plates to meet the rolling technology requirements, and therefore the magnesium-alloy-plate rolling uncoiler unit can improve the rolling quality of the magnesium alloy plates, and solve a problem that traditional uncoilers are not suitable for rolling magnesium alloy plates.
Description
technical field [0001] The invention relates to a mechanical device, in particular to an uncoiler. Background technique [0002] An uncoiler is a mechanical device used to unwind strip steel coils and is widely used in the field of steel plate production. Due to the good plasticity of the steel / aluminum sheet at room temperature, in the traditional steel sheet production process, the annealed steel / aluminum sheet coil can be uncoiled directly on the uncoiler, and then enter the rolling mill for rolling. [0003] However, the hexagonal close-packed structure of magnesium alloys determines its poor plasticity at room temperature. Studies have shown that when the temperature increases to 200°C-400°C, its plasticity increases significantly. Therefore, the deformation of magnesium alloys generally needs to be carried out at a certain temperature. . Put the magnesium alloy sheet and coil directly on the ordinary steel plate / aluminum sheet uncoiler to uncoil, the sheet and coil c...
