Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
Development of the cold planer or milling machine began in the late 1970''s when a grade trimmer was upgraded to mill asphalt pavement. Since that time significant advancements in size, horsepower, milling width, milling depth, production, and costefficiency have been made. CP
A Cold Mill rolls coils of pickled steel from the pickle line at ambient temperature, using coolant oil. The cold mill produces steel and stainless steel and is also used for aluminum, aluminum foil, and copper. There are several types of mills such as 2High, 4High, 6High, 12High, 20High, and Sendzimir Mills that have a variety of types of flatness control operations.
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
In this, pickling line is linked with cold rolling mill, which provides better shape control, delivers significant improvements with regard to mill productivity, yield, and production as a result of the elimination of strip threading and tailingout operations.
tandem rolling mill or continuous rolling mill: tandem rolling mill process. It is a modern rolling mills and the rolling is done by one pass. The rolling is done in several passes for traditional several stands and reduction that take place successive roll. The number of stands like as 2 to 18. Those are either hot or cold rolling mill types.
