Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium processing technical field, specifically, relate to a kind of aluminium alloy wheel belt type continuous casting cooling water regulating control device. BACKGROUND

[0002] Wheel belt casting technology is a new type of aluminium alloy production technology, which realizes continuous casting and online shearing production of aluminium alloy ingot through wheel belt casting machine. This technology has short production process, low investment, low production cost, environmental friendliness, stable product quality, low silicon segregation, and performance indicators such as pinhole degree, grain size, hardness, tensile strength and elongation reach high standards.

[0003] The process includes furnace, ladle, wheel belt rotation crystallization, hydraulic cutting, rolling and coding, and rolling shear steps. The aluminum water is crystallized by wheel belt rotation cooling, and the cooling efficiency is improved after spraying water with compressed air. The aluminum alloy production speed is greatly improved, the process is coherent, and the energy loss is reduced. The steel belt is cooled by water spraying, and heat exchange is carried out by steel belt rotation, which greatly reduces the continuous casting and rolling process, reduces production cost, greatly improves production efficiency, and reduces energy consumption by more than 30%. The continuous casting technology is easy to realize mechanization and automation, and the ingot can be continuously cast and rolled during casting, which greatly improves the production efficiency. In the process of semi-continuous casting of aluminum alloy, the management and water quality control of circulating cooling water have important influence on casting process, equipment and environment.

[0004] The existing aluminum alloy wheel belt type continuous casting machine cools the casting blank in four directions of inside, outside, inside and outside. Specifically, the cooling water pipe is composed of four semicircular bent pipes, which are distributed in the inner circle, outer circle and left and right sides of the crystallization wheel. Cooling water nozzles are installed on the pipe wall. When the aluminum liquid is poured into the crystallization cavity from the small ladle, the cooling water pipe provides cooling water spraying on the crystallization wheel and the steel belt to take away the heat of the aluminum liquid and complete the casting. If the cooling water control is not accurate, it will lead to coarse grain size of casting blank, formation of cavity in the center, affecting subsequent processing, and products with strength not meeting the requirements, product section hollow, etc. Therefore, it is necessary to develop a cooling water flow regulating control device that can accurately control each region.
