Abstract
The invention discloses a magnesium alloy plate strip material rolling device, which comprises a rolling mill, two heating heat insulation boxes and a forced cooling device, wherein the two heating heat insulation boxes are respectively arranged at two sides of the milling machine, the forced cooling device is arranged between the heating heat insulation boxes and the rolling machine, and a coiling machine or a guide roller is arranged in the heating heat insulation boxes. Magnesium alloy plate strip materials coming out from the heating heat insulation box at one side enter the rolling mill to be subjected to cold rolling after being cooled by the forced cooling device and then enter the heating heat insulation box at the other side to be subjected to heat insulation annealing treatment, and the processes are repeated until the materials are rolled to the required thickness. After the magnesium alloy plate strip materials are subjected to the cold rolling and the heat insulation annealing treatment, the grain refinement is uniform, and research shows that magnesium alloy can show good superplasticity when the grain size is smaller than 10 mum. Therefore, the magnesium alloy plate strip material rolling device has the advantages that the mechanical performance of the magnesium alloy is improved, particularly, the plasticity of the magnesium alloy is obviously improved, in addition, the cold rolling and the heat insulation annealing treatment are repeated production processes, and the continuous large-batch production requirements can be met.
Description
Technical field
The present invention relates to a kind of rolling equipment, particularly a kind of rolling device of magnesium alloy plate and belt.
Background technology
In the last few years, fields such as Aeronautics and Astronautics, automobile, 3C Product and military project constantly increased the demand of magnesium alloy, and the requirement of its mechanical property is also improved constantly, and traditional cast magnesium alloy can't meet the demands gradually.In this case, the wrought magnesium alloy product that adopts plastic working techniques such as extruding, rolling, forging to produce more and more comes into one's own owing to have better mechanical property, diversified structure.Wherein, rolling important means as the magnesium alloy plastic working has obtained significant progress, has produced multiple milling method.
Publication number is that the patent documentation of CN1827250A discloses a kind of rolling device that magnesium alloy strip coil is produced that is used for; This device is formed by batching heater incubator, coiling machine, jockey pulley, middle heater incubator; Two coiling machines are separately positioned on the both sides of milling train; And be installed in the batching in the heater incubator of both sides simultaneously respectively, batch be provided with between heater incubator and the milling train in the middle of heater incubator, jockey pulley is installed in the heater incubator respectively.This device increases heating and heat-insulating device in the coiling machine and the porch of milling train both sides, and when magnesium alloy rolling, magnesium alloy strip coil keeps required deformation temperature all the time equably; Though this device has overcome the low difficult point of magnesium alloy temperature-room type plasticity through hot rolling, hot rolling makes that magnesium alloy crystal grain is thick, and is very unfavorable for the mechanical property of magnesium alloy.
Summary of the invention
In view of this, the invention provides a kind of rolling device of magnesium alloy plate and belt, can produce the uniform magnesium alloy plate and belt of grain refinement, improve the mechanical property of magnesium alloy, and satisfy continuous requirement of mass production.
The rolling device of magnesium alloy plate and belt of the present invention; Comprise milling train, heater incubator and forced cooling device; Said heater incubator is two and is separately positioned on the milling train both sides; Said forced cooling device is arranged between heater incubator and the milling train, is provided with coiling machine or deflector roll in the said heater incubator.
Further, said forced cooling device is two and is separately positioned on the milling train both sides;
Further, said forced cooling device is a blower fan.
Beneficial effect of the present invention is: the present invention has increased heater incubator in the milling train both sides; And between heater incubator and milling train, be provided with forced cooling device; It is cold rolling that the magnesium alloy plate and belt that comes out from the heater incubator of a side gets into milling train through forced cooling device cooling back; The heater incubator insulation annealing that gets into opposite side is again handled, and repeats said process, until being rolled down to required thickness; Magnesium alloy plate and belt is handled through cold rolling and insulation annealing, and grain refinement is even, and research shows; Crystallite dimension is during less than 10 μ m, and magnesium alloy will embody good superplasticity, therefore; The present invention has improved the mechanical property of magnesium alloy; Particularly the plasticity of magnesium alloy is significantly improved, and the cold rolling insulation annealing of the present invention is continuous duplication of production process, can satisfy continuous requirement of mass production.
