Grease lubrication system and method of roller for magnesium alloy rolling

Abstract

The invention provides a grease lubrication system and method of a roller for magnesium alloy rolling. The grease lubrication system the roller for the magnesium alloy rolling comprises a grease sprayer, the grease sprayer comprises a first grease box, a second grease box, sprinklers and a gas storage tank; the first grease box is connected with a plurality of sprinklers through a first oil distributor; the second grease box is connected with a plurality of sprinklers through a second oil distributor; the first grease box is connected with the second grease box; the first grease box and the second grease box are separately connected with a control cubicle; the gas storage tank is connected with a plurality of sprinklers; and each sprinkler is connected with the gas storage tank and the first oil distributor, or each sprinkler is connected with the gas storage tank and the second oil distributor. The grease lubrication system and method of the roller for the magnesium alloy rolling creatively uses grease lubrication to lubricate magnesium alloy rolling and overcomes the problems when using lubricating oil and has the advantages that uniform in distribution, stable in performance, low in usage amount, slow in influence on the roller temperature, and convenient to lubricate the lower surface of an magnesium plate without worrying about recycling at the same time.

Description

technical field [0001] The invention relates to the field of metallurgical processing, in particular to a roll grease lubrication system and method during magnesium alloy rolling. Background technique [0002] The plastic forming of magnesium alloys has become an important direction in the research and development of magnesium alloys. At present, magnesium alloy structural parts are still mainly manufactured by die-casting technology, but die-casting defects such as holes and inclusions greatly reduce the mechanical properties of magnesium alloys. In contrast, magnesium alloy plastically formed parts have a finer structure, more uniform composition, and a denser interior. Therefore, the deformed magnesium alloy has the advantages of high strength and high elongation, and can meet higher design requirements. However, the magnesium alloy The poor plastic deformation ability makes its plastic processing extremely difficult. The plastic forming methods of magnesium alloy mainly ...
