  Hot-rolled billet can be part of the ingot defects such as loose, shrinkage and inter-grain micro-cracks and other welding, will not cause subsequent processing of internal tissue defects; grain with fine grain, the performance of uniform. Hot-rolled aluminum plate surface quality is good, while the mechanical properties and strong ductility, oxidation effect is good.
  haomei Aluminum Hot Rolling Product Category:
  1, hot-rolled plate: the thickness of not less than 7.0mm of aluminum and aluminum alloy sheet, the main varieties are hot-rolled plate, annealing plate, quenching or quenching pre-stretching plate. Hot-rolled thick plate in the hot rolling mill is usually produced by block method, the traditional process is: ingot homogenization - milling surface - heating - hot rolling - length shear - straightening.
  2, hot rolled coil: the thickness of less than 7.0 aluminum and aluminum alloy strip is usually used hot rolled coil production, the products are mainly used for cold-rolled billet, but also for the production of sheet, modern production process is: ingot milling Heating - Hot - heat integration - Hot - rough rolling - Hot - dairy - Batching and weighing - Aluminum plate hot - rolling process.
  Aluminum and aluminum alloy by melting, ingot, all kinds of rolling before the preparation, flat roll, heat treatment and finishing processes into a rectangular section of the single sheet or into the process of forming the material.
  
  1, aluminum and aluminum alloy strip with hot-rolled state, annealed state, various levels of soft state and a variety of heat treatment state supply.
  2, hot rolling before the preparation, including ingot quality inspection, soaking, sawing, milling, aluminum and heating.
  3, semi-continuous casting when the cooling rate is very high, the diffusion process in solid phase is difficult, the ingot is easy to form the internal chemical composition and uneven organization, such as intraocular segregation, so that plastic
  4, ingot surface segregation problems, slag, scarring and cracks and other defects, should be milling (see non-ferrous metal alloy ingot billet milling), which is to ensure good quality of the finished product is an important factor
  5, hot-rolled: aluminum alloy ingot hot rolling is to provide blank for cold rolling, or direct production of hot-rolled plate.
  6, hot rolling process system, including pass down rate, rolling temperature, rolling speed and lubrication cooling.
