Aluminum sheet/coil refers to an aluminum sheet or strip made of aluminum as the main raw material and mixed with other alloying elements. Aluminum strip is an important basic material for the development of my country's national economy and is widely used in aviation, aerospace, construction, printing, transportation, electronics, chemicals, food, medicine and other industries.

Driven by the rapid economic development,and the consumption of aluminum strips continues to maintain a steady growth. The demand for exterior wall construction and interior decoration, aluminum foil manufacturing, printing, PS plate, manufacturing, home appliances ,food packaging and other industries has further increased, becoming the main driving force for the growth of aluminum strip consumption. At the same time,the transportation industry is becoming a new consumption growth point.

Hengzhong Heavy Industry has been committed to the design and manufacture of aluminum strip processing equipment, including casting and rolling mills, cold rolling mills, transverse shearing machines, slitting machines, stretch-bending straightening machines, annealing furnaces, slitters, etc. our rolling mill has the correct mill setting and the most important control system. To ensure excellent rolling results and to produce aluminum strip to tight tolerances and high yields.

Casting

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Hot rolled

Hot rolling generally refers to rolling above the metal recrystallization temperature. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain amount of work hardening. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure.

Cold rolled

Cold rolling refers to the rolling production method below the recrystallization temperature. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the work hardening state will appear in cold rolling, and the work hardening rate will be large. Cold-rolled strips have high dimensional accuracy, good surface quality, uniform structure and performance, and can be obtained in various states with heat treatment.

  Finishing

Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product. Finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter and so on.

Cold rolling is an important part of the process route when manufacturing aluminum strip of various thicknesses and widths. Equipment is particularly critical for the transformation and upgrading of industrial-grade aluminum products to food-grade aluminum products. The production of cold-rolled strips by casting and rolling is a short-process process that has been saving energy and reducing emissions. Any products that can be cold-rolled by this kind of strips can meet the requirements of users should be produced with this kind of strips.
