Description
Technical field
The present invention relates to metallurgical processing fields, and in particular, to roll grease lubrication system and side during a kind of magnesium alloy rolling
Method.
Background technology
The Plastic Forming of magnesium alloy has become the important directions of current research and development of magnesium alloy, and magnesium alloy structural part is still main at present
It is manufactured by die-casting technique, but defects of die casting such as hole, is mingled with etc. and to greatly reduce magnesium alloy mechanical property.In contrast, magnesium closes
The part tissue of golden Plastic Forming more refines, ingredient evenly, it is internal more closely knit, therefore wrought magnesium alloy has high intensity and height
The advantages that elongation percentage, disclosure satisfy that higher design requirement, but the plastic deformation ability force difference of magnesium alloy causes its plasticity to add
Work is extremely difficult, and magnesium alloy Plastic Forming means mainly include rolling, extruding, punching press etc..
During magnesium alloy rolling, temperature must in time be lubricated roll and magnesium plate band when increasing, lubricating system
The deformation heat and frictional heat of metal can be taken away, adjusts roller surface temperature, controls template, ensures rolling efficiency and safety, simultaneously
The friction coefficient between roll and strip can be reduced, stable frictional interface is provided, prevent from occurring between roller and magnesium plate hot glutinous
It, realizes stable rolling, improve magnesium plate surface quality.
Magnesium alloy plastic deformation ability is poor under room temperature, between temperature need to maintain 200~500 DEG C during rolling, but in height
The lower magnesium alloy of temperature easily aoxidizes to form loose oxidation film on surface, this oxidation film easily comes off and is adhered on roll,
Extreme influence rolling accuracy and magnesium plate surface quality, plate face is coarse after making rolling, poor quality, while rolls after the completion every time such as
Fruit roller surfaces have the magnesium oxidation film being adhered, and need to carry out grinding process.
At present, lubricating oil is sprayed on roll surface by magnesium alloy rolling in the form of misty often, if lubricating oil applies deficiency,
Magnesium alloy sticks roller phenomenon and can not eliminate, and roller surface Quench can be made if lubricating oil excessive addition, makes magnesium plate rolling abnormal, occurs
Situations such as various flatness defects or even big crackle of appearance or fracture.On the other hand, when Warm status lubricates, lubricating oil is volatile
Scaling loss had both increased cost and polluted environment simultaneously, if lubricating oil is excessive, needed to be equipped with perfect lubricant recovery device,
It can be seen that there are problems for oil lubrication mode.
The mode of lubricant is typically with hydraulic pump lubricant to be drawn from fuel tank, using oil circuit from mounted on rolling
In the nozzles spray to roll of roller both sides, in the operation of rolling, unsuitable spraying lubricant during interval between each passage, while according to rolling
The difference of speed processed, drafts etc., the usage amount of lubricant is also different, thus the sprinkling of lubricant to accomplish it is convenient controllable.Separately
On the one hand, it is not uniform when magnesium plate is adhered with roll, but the subregion for showing regularity is adhered, this explanation
It is axial variant to the demand of lubricant along roll.
Therefore when finding a kind of magnesium alloy rolling good lubricant and lubricating system magnesium alloy plate is produced to
Close it is important, while it is necessary to entire greasing carry out accurately monitor and control.If current magnesium alloy rolling device is adopted
