Abstract
The invention relates to a method for distorted magnesium alloy strip coil by adopting a strip method to continuously cast and roll, which comprises blending and smelting, stewing, purifying, distributor, continuous casting and rolling, reeling or heat reeling. The invention takes use of the characteristic that melt is formed under a semi-solid state and is distorted through rolling to control the properties of magnesium alloy in a solidification-distortion area through the distributor. The invention makes a metal to become plate and stripe with distortion state from melt, and coils the plate and stripe by a reeler, all these are completed in one continuous casting and rolling pass. After some subsequent processing, the distorted magnesium alloy strip coil got by the method in the present invention can be widely used for mobile phones, digital cameras, vehicle door lining boards and vehicle rear tank caps as well as stacked magnesium battery chips, inner clapboards for planes, food boxes and other aspects.
Description
Technical field:
The present invention relates to technical field of nonferrous metal processing, is a kind of method of utilizing the belt method to carry out continuously casting and rolling to produce deformed magnesium alloy tape volume.
Background technology:
At present, in the process of wrought magnesium alloy, adopt 2 kinds of technologies mostly: 1, batching and melting-semi-continuous casting (slab ingot)-mill face-flaw detection-sawing-homogenizing annealing-heating-hot rolling-warm-rolling/cold rolling-finishing-surface treatment-operations such as goods packing;
2, batching and melting-horizontal casting (slab)-mill face-flaw detection-sawing-homogenizing annealing-warm-rolling/cold rolling-finishing-surface treatment-operations such as goods packing.
Above-mentioned 2 kinds of technological processes are long, and slab all is difficult to plastic working at normal temperatures, and yield rate is low, only are about 20% as 1.0mm magnesium alloy thin plate and band yield rate, and have that energy resource consumption is big, metal loss is many, cost is crossed high defective.And these 2 kinds of processes can only carry out one chip production, can not adopt the belt method to carry out continuous rolling as copper, aluminium and copper material, so efficient is very low.
Summary of the invention:
For overcoming deficiency of the prior art, the invention provides a kind of method of utilizing the belt method to carry out the continuous casting and rolling deformed magnesium alloy tape volume, solve a difficult problem that is difficult to plastic working under the magnesium alloy normal temperature, continuously casting and rolling to produce deformed magnesium alloy tape volume is carried out in the industrialization of realization belt method.
For achieving the above object, the present invention adopts following processing step:
Batching and melting, leave standstill, purification, distributor, continuous casting and rolling, batch/or the heating batch.Utilize melt under semisolid, to be shaped and stand the characteristic of rolling deformation,, control the proterties of magnesium alloy " solidifying-deformed area " by distributor.The realization metal, carries out the roll coil of strip through devices for taking-up again and batches to the strip material with deformation state from melt, directly finishes through a continuous casting and rolling operation passage.
Beneficial effect:
The inventive method is compared with existing technical matters, operations such as the face of milling, flaw detection, homogenising processing, sawing have been saved, the method of wood invention organically combines foundry engieering and rolling technique, operation of comprehensive one-tenth is finished, it is a kind of nearly end form process technology of new shape, can significantly improve magnesium alloy plasticity, enhance productivity greatly, reduce energy resource consumption significantly, meet the national industry developing direction; The roll coil of strip material structure that the inventive method is produced is better than the alloy structure that the existing level continuous casting is produced, and adopts deformed magnesium alloy tape volume that the inventive method produces can be widely used in mobile phone, digital camera, automobile door lining and deck and folded formula magnesium cell sheet, aircraft with aspects such as internal partition, food casings through the product of following process.
Description of drawings:
Fig. 1: process chart.
Embodiment one:
Batching and melting: the raw material for preparing is dropped into smelting furnace carry out melting, the melt tapping temperature is controlled again between 680～780 ℃.
Embodiment two:
Leave standstill: stove is left standstill in the magnesium alloy fused mass importing of fusion leave standstill.
Embodiment three:
Purify: the magnesium alloy fused mass that leaves standstill imports purifier and carries out overanxious.
Embodiment four:
Distributor: the melt after the purification imports distributor, and distributor is the fan-shaped casing of front-thin-rear-thick, and its inner chamber has the branching block more than 2; Distributor is arranged on the continuous casting roll gap central horizontal face; Magnesium alloy fused mass is flowed to the roll gap of accurately adjusting between two rolls equably by distributor; From melting, leave standstill, be purified to export distributor and all adopt the N that contains 1～2 ‰ SF6
2Protective gas is protected.
Embodiment five:
Continuous casting and rolling: adopt two inner-cooled rolls up and down of continuous casting configuration, roll-force is controlled between 400～1000t, and mill speed is controlled between 600～2500mm/min.When magnesium alloy fused mass contacts with roll because of rapidly the cooling crystallization, " colony " of crystallization just is broken to cause more nucleus but because the impact of follow-up superheated melt causes, thereby produce the metal turbulent flow, under the metal action of turbulent flow, " solidify-deformed area " forward position and form semisolid, when metal arrives at two roller gap center lines then, because the metal turbulent flow, the triple role of cooling, pressure processing forms the strip material with ultrafine-grained's (average grain size: about 20 μ m) rapidly, deformation extent can reach 5～15%.
Embodiment six:
Batch: adopt the devices for taking-up be configured in the continuous casting and rolling drive end unit that the strip material of casting is carried out on-line synchronous and batch, coiling speed is controlled between 600～2500mm/min, batches internal diameter and is controlled between Φ 250～650mm.
Embodiment seven:
Heating is batched: at the goods of specific (special) requirements, the assisted heating device that employing is configured in the continuous casting rear portion carries out being implemented in line locking after the online heating to goods and batches, coiling speed is controlled between 600～2500mm/min, the temperature of heating is controlled between 150～350 ℃, batches internal diameter and is controlled between Φ 250～650mm.Final continuous casting and rolling is produced the deformed magnesium alloy tape volume that specification is 2.0～10.0X300～1600mm.
The specific embodiment:
At first that proportioning is good raw material drops into smelting furnace and carries out melting; The temperature control again between 680～780 ℃ that melt is come out of the stove and entered distributor inlet; Magnesium alloy fused mass imports distributor after leaving standstill, purifying, melt is distributed the roll gap flow between two rolls that continuous casting configures equably through distributor; From melting, leave standstill, purify to export distributor and all adopt the N that contains 1～2 ‰ SF6
2Protective gas is protected; Continuous casting and rolling adopts roll-force to be controlled between 400～1000t, and mill speed is controlled between 600～2500mm/min; Carry out on-line synchronous through devices for taking-up and batch, coiling speed is controlled between 600～2500mm/min, batches internal diameter and is controlled between Φ 250～650mm; Also can adopt auxiliary mode of heating to carry out the online hotsync that adds at the goods of specific (special) requirements and batch, heating and temperature control is between 150～350 ℃, and coiling speed is controlled between 600～2500mm/min, batches internal diameter and is controlled between Φ 250～650mm.
