The difference between aluminum alloy continuous casting and rolling and aluminum alloy continuous casting and rolling
Mar 31, 2021
In the continuous casting and rolling process, the casting process and the rolling process are completely synchronized; while the aluminum alloy continuous casting and rolling process is to complete the continuous casting first, and then complete the rolling of the billet on the subsequent hot rolling mill.

Characteristics of aluminum alloy continuous casting and rolling:

1. The equipment is simple and centralized, which shortens the time from molten aluminum-ingot-ingot processing-hot-rolled strip, saving ingot casting, sawing, milling, ingot heating, billeting, hot rolling, etc. The working procedure simplifies the production process, shortens the production cycle, improves labor productivity, and has a high degree of automation;

2. Energy saving and consumption reduction, reasonable configuration of the production line of continuous casting and rolling technology, compact structure and convenient operation, reducing the energy consumption of a series of processes required for hot rolling;

3. Few geometric wastes such as cutting heads and tails, high yield rate and low production cost;

4. Due to the thin thickness of the continuous cast-rolled strip, it can be directly cold-rolled after cooling, which saves the electricity and heat consumed by the high-power hot rolling mill and the heating of the ingot;

5. The equipment investment is small, the effect is quick, the investment recovery period is short, the area is small, the construction speed is fast, and it is suitable for the construction of small and medium-sized aluminum sheet and strip enterprises;

6. Continuous cast-rolled billets can completely replace hot-rolled billets for the production of aluminum and aluminum alloy plates, strips and foils;

7. Part of the recycled waste can be used as raw materials, the production cost is low, and the price is quite competitive.

Features of aluminum alloy continuous casting and rolling:

1. Due to the thin thickness of the continuous casting and rolling slabs, and the direct rolling with waste heat, high-power hot rolling mills, ingot heating equipment, and milling equipment are saved;

2. The production line is simple and centralized. From smelting to rolling out of the strip, the product can be carried out continuously in one production line, which simplifies many intermediate processes such as ingot sawing, milling, heating, hot rolling, transportation, and simplifies the production process. , Shorten the production cycle;

3. Less geometric waste and high yield;

4. High degree of mechanization and automation;

5. Low equipment investment and low production cost.
