The difference between cold-rolled and hot-rolled aluminum sheet alloys

In the aluminum sheet industry, there are many different types of 4 x 8 aluminum sheet, which can be divided into many models in different ways. When classified according to different production processes, aluminum sheet alloys can be divided into cold-rolled aluminum sheets and hot-rolled aluminum sheets. What is the difference between them? Let's find out together!
The difference between cold-rolled aluminum sheet and hot-rolled aluminum sheet is as follows: First, the production process is different. The production process of cold rolled aluminum sheet starts with a cast slab (8 mm thick) made by a casting machine, which is then rolled by a cold rolling mill. Hot rolled aluminum sheets are made by heating aluminum ingots (400-500 mm thick) and then rolling them at high temperatures with a hot rolling mill. Second, the supply of different raw materials. Hot rolled billets are aluminum ingots cast by heating and rolling, and cold rolled billets are cast rolls used for cold rolling. Third, the performance is different. Hot rolled aluminum sheet has good surface quality, oxidation effect, bending properties, and strong mechanical properties and ductility. Cold-rolled aluminum sheets have poor mechanical properties and high hardness, so cold-rolled White Aluminum Sheet are often used as mold materials, and hot-rolled aluminum sheets are more suitable for deep drawing. Generally speaking, the internal structure of hot-rolled aluminum sheet is stable and uniform, the hot-rolling process is complicated, and the price is higher than that of cold-rolling. At present, the 1 and 3 series aluminum sheets on the market are cold rolled, and the other series are hot rolled, but the 1 and 3 series can also be produced by hot rolling, but the price is higher. No matter hot-rolled or cold-rolled aluminum sheet alloy, what you need is the best, while searching for aluminum sheet, why not come to Huawei? We have high quality aluminum sheet products, if you have any questions, please contact us, our staff are always waiting for your visit.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
