　　The purpose of hot rolling in aluminum sheet production is to provide ingot for cold rolling or to produce thick aluminum plate of hot rolling state. There are three types of methods for hot rolling if classified by production scale: single-stand, double-stand and half continuous hot rollings. 　　With single-stand hot rolling all relative processes, from cogging to hot rolling, are finished in one stand. Efficiency can be improved by application of large ingot and reverse mill. Four high driven mill helps to enlarge width and improve shape of aluminum sheets. The disadvantage of single-stand hot rolling is dissatisfying quality and efficiency because of quick fall of sheet temperature, large sheet thickness and relatively light sheet weight. Double-stand hot rolling consists of a reverse mill and a four high reverse driven mill. The first mill deals with cogging and rough rolling, then the plates are transferred to the second mill for precise rolling. In this way, rough rolling a...

　　Aluminum foil flexible pipes can deliver all kinds of media of temperatures between -50℃ and 150℃. They are applied in heat or cold maintaining projects for centralized heating, central cooling and hot oil delivery in industries like petroleum, chemical, coal, refrigeration and heating supply. Although you may have caught sight of the pipes a lot in daily life, you might not pay enough attention to their structures. 　　Generally speaking, an aluminum foil flexible pipe consists of four parts: delivery tube, heat preservation layer, protective shell and alarming lines. There are different types of delivery pipes in accordance with technical requirement for medium to be delivered. A pipe may be equipped with delivery tubes of seamed steel, seamless steel as well as helical welded steel with submerged arcs on both sides. Heat preservation layer normally adopts hard polyurethane foaming plastic as raw material. It has necessary strength and flexibility. Besides, foaming plastic with...

　　Aluminum circle packaging proves to be crucial because inappropriate packaging may lead to damage, deformation or oxidation of aluminum circles. Then what are cautions for aluminum circle packaging? 　　First, tic-tac-toe frame is usually chosen for aluminum circle packaging. The frame consists of four wooden bars, two fixed above and the other two below. The upper bars must be made into arches and fixed by bolts. The height of lower bars must meet requirements for forklift. These bars are also fastened with bolts, which should be below the upper arches so that packed circles will not be damaged. Second, it’s necessary to wrap aluminum circles with a layer of cloth with medium property or weak acid before putting packaging sheet into the cloth. Connecting parts must be fixed with packaging tapes. Both the top and bottom side of packed circles should be covered by soft pads to protect them from scratches. Third, wrap stacks of circles and drying agents with plastic cloth which sho...

　　Rapid development of industry classification has made manufacturing of aluminum circle a separate business scope. Serving as raw material for cookware and lighting industries, aluminum circle is taking up larger and larger share in global market. In spite of huge sources of suppliers, purchasers become more vigilant than before, because it entails more skills to pick quality aluminum circle out of numerous samples. 　　What features do quality aluminum circles have? As components for further production, they must have high precision in size. Even slight errors are likely to lead to serious consequence in manufacturing of electrical or aerial products. Besides, quality aluminum circles have smooth and bright surface. Some manufacturers adopt damaged raw material to save cost. If not kept properly, the surface of raw material may get oxidized or even be covered with scratches. Inappropriate production procedures can lead to damage of the circles, too. 　　Except for checking sampl...

　　 Aluminum sheet wardrobes are winning popularity with promotion efforts of aluminum manufacturers as well as environmental trend. If you want to follow this fashion, you’d better learn something about wardrobe designs first. Here are some advice. 　　How much do you know about the height of each unit of aluminum sheet wardrobes? Generally speaking, the unit for hanging short jackets should be no less than 800mm tall, that for long coats 1300mm and drawers from 150mm to 200mm. Units for stacking suits and other smaller clothes is usually 350 high and from 330mm to 400mm wide. The upper part of an aluminum sheet wardrobe, commonly used for keeping bulk items like quilts, should be 400mm tall at least. 　　In addition to universal standards for aluminum sheet wardrobes, your design should also vary from people to people. It’s key to meet requirements of people from different age scopes. Wardrobes for the old must be convenient for taking out and putting in clothes. There’s no need...

　　 Anodized mirror aluminum sheet refers to aluminum sheet with reflective property. It’s obtained by rolling mill and polishing of common aluminum plate. Finished aluminum mirror sheet serves as reflective material in various industries. Its typical applications include lighting covers, solar panels, interior decorative boards etc. Then how is the sheet classified? As large scale raw material for varied manufacturing areas, aluminum alloys have a seemingly clear classification in production specifications yet extremely confusing categories in application fields. 　　Generally speaking, anodized mirror aluminum sheet is classified for convenience of production and selling. There are mainly two types: pure aluminum sheet and alloy sheet. Common pure sheet includes 1050, 1070 and 1085. the first two alloys prove to be more widely applied than 1085, because their manufacturing process have developed maturely, and singular processes make it possible for manufacturers to supply them eff...

　 Aluminum foil price , similar to price of any other aluminum products, varies almost from day to day. Experienced buyers would try to find out rules by tracing government policies and market states and calculate best time for putting orders. Their efforts do have fruit. What’s the secret, then? 　　Since there are so many factors influencing aluminum foil price, there are no stable answers to this seemingly simple question, but we can learn something by studying the factors. The first factor proves to be aluminum ingot, the price of which changes daily. You must pay attention to the price chart every day. Second, quality influences aluminum foil price, which is apparent, because quality always matches price. Raw material quality, production technology, experience of workers all have impact on quality of finished aluminum foil. Third, specification influences aluminum foil price. Foils of equal quality involve different processes if clients ask for varied specifications, because co...
