What is cast rolled coil

In our aluminum plate and strip industry, casting and rolling coils are often mentioned, and many users may not understand what casting and rolling coils are. Here, Lvmeng Aluminum will provide you with a detailed explanation of the common knowledge of casting and rolling coils.

Firstly, the cast rolled coils we mentioned are all aluminum cast rolled coils, which refer to the preliminary processed coils with a thickness between 8.0-10mm processed by a cast rolling mill. It can also be considered that cast rolled coils are billets used as raw materials for the production of various cold rolled aluminum sheets and strips. Currently, most aluminum sheet and strip production enterprises are outsourcing cast rolled coils, as most of the enterprises producing cast rolled coils are electrolytic aluminum enterprises, which directly process liquid aluminum water into cast rolled coils, Eliminating the melting process saves a significant amount of electricity, while also avoiding the consumption of aluminum ingots during melting, resulting in lower costs for purchasing cast and rolled coils.

Why choose cast rolling coil: In terms of cost, we can provide a detailed account for the cast rolling coil. Usually, the processing cost for a series of cast rolling coils is around 700-800 yuan. However, if we use aluminum ingots for cast rolling, only 5% of the consumption will be around 750 yuan. At the same time, we also need to bear the electricity cost and labor costs of melting the aluminum ingots in various processes. Therefore, it is more cost-effective to directly purchase cast rolling coils, As an electrolytic aluminum enterprise, directly producing cast rolled coils is also much more cost-effective than aluminum ingots. Therefore, cast rolled coils are currently circulating in cold rolled aluminum sheets. Nowadays, few enterprises choose to use aluminum ingots, but in the hot rolling industry, melting furnaces must be carried out and alloy costs must be allocated. Therefore, hot rolled aluminum sheet enterprises must use aluminum ingots.

Summary of advantages and disadvantages of cast rolled coils: The advantages of cast rolled coils are self-evident, which can effectively reduce production costs and shorten production cycles. The disadvantage is quality control, as cast rolled coils are produced in electrolytic aluminum plants, and enterprises cannot grasp first-hand information. They must be inspected during use, and sometimes quality issues may arise.
