plate and strip cold rolling mill is important equipment in metallurgy industry. as one kind of them, magnesium alloy cold rolling mill can roll the rolled and finished planks under the condition of medium and normal temperature certain passes to be strips with ideal thickness based on the requirements of plate and strip material rolling process. they can be rolled into strips and coils based on the requirements of process.magnesium alloy cold mills have various classifications. according to the quantity of rollers, they can be classified into four-high cold mills and six-high cold mills. they also can be divided into small-size, medium-size and large-size mills based on specification. four-high mills of magnesium alloy cold rolling mill which were put into production were predominant at that time. while the main international products are updated to six-high cold mills at present.
as the earlier enterprise that produced metallurgical mills at home, nhi has provided dozens of cold rolling mill for a variety of companies for years. at present, nhi can produce large-size and medium-size magnesium alloy cold mills of different specifications. in 2013, nhi succeeded in developing the world’s first high-performance outfit which is four-high cold rolling with the widest format of 1650mm and won the invention patent, which filled the gap at home and abroad. it absolutely changed the history in which there
were no strips but plates in the field of magnesium alloy cold mills. nhi is a domestic enterprise that has mastered all the techniques of research and development, design, production and commissioning of magnesium alloy cold rolling mill. it has an important position in the research and development field of domestic magnesium alloy production equipment.
