Hliníkový kruh na nádobí

What is Aluminium circle for cookwares

Hliníkový kruh pro nádobí obvykle označuje kus nebo kruh kruhového tvaru vyrobený z hliníku, který se používá při výrobě různých typů nádobí., jako jsou hrnce, pánve, a kuchyňské náčiní. These aluminium circles serve as the base or body of the cookware and are an essential component in their construction.

Aluminium circle have good formability, vysoká odolnost proti korozi, burnability, únavová pevnost a střední statická pevnost. They can be made into cookware through stamping or spinning processes.

Why use aluminium circles to make cookware

About half of the world’s cookware is made of aluminum, with a cooking thermal efficiency of up to 93%, while stainless steel and cast iron are only 1/3 of aluminum. Using aluminium circles to make cookware will greatly increase the physical and chemical properties of the cookware, so that the electrical conductivity, tepelná vodivost, heat resistance and other characteristics of the cookware can be improved, providing guarantee for making delicious food.

Characteristics of aluminium circle suitable for making cookware

hliník, as a metal with extremely high thermal conductivity, does not rust and remains resistant to many types of corrosion.

Since aluminum is prone to oxidation in areas where anodization has not occurred after long-term contact with some foods, a small amount of other metal elements are added to the aluminum material when making cookware to improve performance.

Aluminum is generally available in drawn, die-cast or anodized forms. Drawn aluminum is formed by rotary stamping.

Since aluminum is relatively soft, hořčík, měď, and bronze are added to make aluminum alloys to increase strength.

Die-cast aluminum is often thicker than stretched aluminum, making this structure more suitable for heavy soup pots.

Since die-cast aluminum is prone to tiny pores during production, its thermal conductivity is much lower than that of stretched aluminum.

Anodized aluminum forms a layer of oxide on the surface, which plays a protective role. It is hard and does not easily react with other substances.

V současnosti, most cookware on the market is based on manganese-aluminium alloy. The combination of manganese and aluminium metals in cookware manufacturing can effectively enhance each other’s physical and chemical properties.

Cookware aluminium circle production process

The most advanced equipment for the production of finished aluminium circles is the cookware aluminium circle uncoiling and blanking production line. Such an automated production line is a fully automatic and integrated aluminum circle production equipment, which can effectively improve material utilization and is far superior to other circles. Blanking method.

The aluminum circle uncoiling and blanking production line equipment can directly complete the stamping and blanking of circles on the aluminum coil without slitting and shearing. The product is widely used in the aluminium processing manufacturing industry, such as drawn aluminium circles for cookware and other industries.

Cookware production process

The production process of cookware mainly includes blanking, výkres, buckling, bottom finishing and cleaning.

In the blanking process, the metal materials for making cookware must first be screened. Since cookware needs to maintain good thermal conductivity and at the same time achieve stable chemical properties during high-temperature barbecues, the metal materials used to make cookware have a strict inspection scope.

The deep drawing process is mainly completed on a hydraulic press with the help of molds. There are basically two types of production molds: concave molds and punch molds, or called static molds and movable molds. The process of deep drawing deformation is to force the material to pull down in the concave mold through the downward pressure of the punch, and gradually form the prototype of the cookware.

The selection of the mold satisfies the requirements of wear resistance, strong toughness, low fatigue fracture performance, good anti-tempering stability, cold and hot fatigue resistance, a odolnost proti korozi.

Specifications of aluminium circle for cookwares

Common aluminum circle for cookwares

Generally common aluminum circles are mainly 1050-0 nebo 1050 polotvrdý. V tomto stavu, they will not crack during stamping, předení, atd. during the later production process. Elektrické spotřebiče, hrnce, atd. produced from circles have good heat dissipation, do not rust, are lightweight and have a long service life.

Which alloy of aluminum circles should I choose for cookware?

Aluminum circles are mainly 1000 series aluminum circle, 3000 series aluminum circle, 5000 series aluminum circle, 6000 series aluminum circle, a 8000 series aluminum circle. The most wildly used aluminum grades are: 1050, 1060, 1100, 1200, 3003, 5052, 6061,8011. The aluminum states (nálada) are O, H12, H14, H16, H18, atd.

Pure hliníkový kruh 1050 are made of fresh aluminum ingot and the purity is over 99.5%, so it is also named 99.5 pure aluminum circles. Například, hot-rolled aluminum circles are suitable for the production of kitchenware in the deep-drawing process, with a deep-drawing rate of ≥1.8; 1050 aluminum circles are suitable for the production of hydraulic or deep-drawing lamps and lanterns; cold-rolled aluminum circles are suitable for the production of kitchenware in the late spinning process.

Wide application of aluminum circles

The use of aluminum circles has increased in recent years. Hliníkové kruhy jsou široce používány v elektrických spotřebičích, izolace, strojní výroba, automobilů, letectví a kosmonautiky, vojenský průmysl, formy, konstrukce, tiskařský a další průmyslová odvětví, jako jsou kuchyňské potřeby, jako jsou nepřilnavé pánve, tlakové hrnce, atd. and hardware Supplies such as lampshades, pláště ohřívačů vody, atd. are one of the most widely used aluminum plate deep-processing products.

Používání: lampy, stínidla na lampy, kuchyňské potřeby, hliníkové hrnce, hliníkové konvice, hliníkové mísy, rychlovarná konvice tepelně vodivý podvozek, vložka do rýžovaru, bezdýmné hrnce, jemné železné hrnce, Evropské hrnce, nepřilnavé pánve, hliníkové lahve, aluminum barrels, dopravní značky , některé hliníkové kondenzátory, polotovary hliníkového pláště kondenzátoru.

Why choose huawei aluminum circle for cookware

Aluminum circles used inside the manufacturing of kitchenware have very high requirements for surface and performance. It requires the floor of the circle to be brilliant and flat to make certain no obvious scratches, olejové skvrny, oxidace, černé skvrny, a tak dále. When the thickness of the circle is >1.0mm, the finished product is assured to be neat and burr-loose at the edges.

As a expert aluminum round sheet producer, they’ll have correct control at the grain size and elongation of the grasp roll of the aluminum coil to make sure the exquisite deep punching and spinning performance of the aluminum spherical sheet, and correctly keep away from bad phenomena inclusive of orange peel pattern, ruffled side and high ear-making rate which can arise in the later processing.

Slitina, country, and overall performance of the aluminum coil are strictly managed and examined to make certain the accuracy and variety of the furnished aluminum circles.

Commonly exceptional troubles: orange peel problems; destroy trouble, surface oxidation, 4 ears. Surface nice mill finishes no oil stain, žádné škrábance, valivé značky, or orange peel trouble.
