Aluminum billet casting process and continuous rolling process began in the 1980s and are an advanced production process.
The basic process is: aluminum ingot → melting furnace → static furnace → degassing → filtering → casting nozzle → rolling mill → intermediate unit → coiler.
Aluminum billet casting process characteristics
Continuous casting and rolling is to cast aluminum solution into ingots with a certain thickness (generally about 20mm thick) or a certain cross-sectional area (generally about 2000mm2) through a continuous casting machine, and then enter the subsequent single-stand or multi-stand hot (warm) plates Strip mills or wire pass mills for direct rolling into sheets for cold rolling, strips or billets for drawing and other finished products. Although casting and rolling are two independent processes, continuous casting and rolling are a continuous production process because they are carried out continuously on the same production line.
The aluminum billet casting process is to cast and roll molten aluminum into a slab with a thickness of 6-10mm and a width of 650-1400mm, coil it, and then directly send it to a cold rolling mill for finishing. In this way, in the production process of aluminum sheet and strip, ingot casting, heating, hot rolling, billeting and other processes are omitted, which not only shortens the technological process of aluminum sheet and strip production, greatly reduces engineering construction funds, but also reduces the production process. The metal is burnt out, energy is saved, and at the same time, the continuous production of aluminum sheets and strips can be conveniently realized.
It is used for cold-rolled coils of aluminum and aluminum alloys. Through the unit’s uncoiling head cutting, edge trimming, joint stitching, surface cleaning, drying, stretching and side bending straightening, board surface inspection, coiling and rectifying processes, a flat, clean, uniform color and neat shape can be obtained. product. It is suitable for the production of high-quality products such as flat stone, no grease, surface water, paint coating, decoration and lamination.
It is used for transverse shearing of hot-rolled or cold-rolled aluminum and aluminum alloy strips or sheets with different length requirements. The machine line is composed of uncoiling, feeding, cutting head flattening, trimming waste processing, roller leveling, measuring and shearing, stacking and other equipment.
Main product index material: aluminum and aluminum alloy,
Thickness: 0.3-12mm (design according to different thickness)
Cutting length: 500-4500mm
Train speed: 90m/min.
The main advantages of strip casting and rolling:
1.Due to the thin thickness of the continuous casting and rolling strip and can be directly rolled with waste heat, it saves high-power hot rolling mills and ingot heating equipment, and milling equipment;
2.The production line is simple and centralized. From smelting to rolling and stripping, the products can be continuously processed in one production line, which simplifies many intermediate processes such as ingot sawing, milling, heating, hot rolling, and transportation.
order, simplifies the production process and shortens the production cycle;
3.A lot of geometric waste, high yield;
4. High degree of mechanization and automation; 5. Less investment in equipment and low production cost.
The main advantages of wire billet continuous casting and rolling:
1.The transportation of ingots, repairing ingots and ingots is omitted, and the heating process and heating equipment are omitted;
2.The degree of mechanization and automation is improved, which greatly improves the working conditions;
3.The rolling piece passes through the machine in a straight line, and the temperature drop is small, which reduces the torsion of the rolling piece and the phenomenon of sticking, scraping, and touching with the equipment, and the surface quality is high;
The quality of the coiled wire blank is not limited, and the coil weight of the wire blank can reach more than 1 ton, which greatly reduces the number of welding heads and improves the production efficiency;
The equipment is small, light in weight, small in land occupation and convenient in maintenance.
Continuous casting is an intermediate link between aluminum-smelting and steel-making and aluminum-rolling and steel-rolling, and is an important part of the smelting industry. Whether it is the aluminum billet casting process or the steel billet, the application of continuous casting technology has completely changed the production process and logistics control of the smelting workshop, providing continuous production in the workshop, the application of automation and information technology, as well as greatly improving the environment and improving product quality condition.
In addition, the development of continuous casting technology will also drive the development of other industries in the metallurgical system, which has an important role in promoting the simplification and optimization of enterprise organizational structure and product structure.
