Abstract
The present invention relates to a technical method for vertical casting of aluminum bus. By adopting the technique of vertical casting the invention is characterzied in that the technological parameters in production are as follows: 1) aluminum content in aluminum liquid used in casting is more than 99.65 percent, content of impurity is less than 0.35 percent, and ratio of Fe to Si is limited between 1.2 to 1.5; 2) casting termperature is limited between 720 to 730 DEG C; 3) casting speed is controlled between 80 to 100mm per minute; 4) the distant between level of the aluminum liquid and the upper inner rim of crystallizer is 2.0cm. The present method can remarkably improve the passing rate of product. In practical production, the present method can control heat crack, curve and twist of the aluminum bus and can reduce the production cost of the aluminum bus.
Description
Technical field
The present invention relates to a kind of aluminium bus vertical casting technology method.
Background technology
Need a large amount of high-quality aluminium busbars in electrolysis production, the quality of its quality directly influences the security of operation of electrolytic cell capital construction installation and produces indicator of power consumption etc.Past, all adopt rolling calendering bus at aluminium bus of electrolyzer, it exists-serial shortcoming: technology make complicated, energy consumption is high, each diversity serious, current unevenness, connection voltage height and production cost are high.In recent years along with aluminium cell to large scale development, its negative busbar, anode bus, riser bus bar have all adopted the casting aluminium busbar of big section, and this product has mechanical strength height, easily processing, can realize low current density, easily current-sharing and many advantages such as energy-saving and cost-reducing.Casting big bus has horizontal casting and vertical shaft casting dual mode, and the vertical shaft type casting has difficult generation chemical composition segregation again, factory takes up an area of the characteristics little, that output is high, has a extensive future.But its production technology is difficult to grasp unstable product quality.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, provides a kind of production technology to be easy to grasp the aluminium bus vertical casting technology method of constant product quality.
The objective of the invention is to be achieved through the following technical solutions.
A kind of aluminium bus vertical casting technology method adopts vertical casting technology, it is characterized in that the technological parameter of its production is:
1) Jiao Zhu aluminium liquid contains aluminium more than 99.65%, and impurity content is not more than 0.35%, and Fe/Si ratio is controlled between 1.2～1.5;
2) casting temperature is controlled between 720～730 ℃;
3) casting speed is controlled at 80～100mm/min;
4) horizontal plane of aluminium liquid upper limb 2.0cm in the crystallizer.
Because casting technological parameter conditions such as the chemical analysis of the perpendicular casting formula aluminium busbar of casting, temperature of aluminum liquid, casting speed all can impact the quality of perpendicular casting formula aluminium busbar, adopt method of the present invention, product percent of pass obviously improves; In actual production, the fire check of aluminium busbar, bending, distortion are under control; Reduced the manufacturing cost of casting aluminium busbar.
The specific embodiment
A kind of aluminium bus vertical casting technology method adopts vertical casting technology, and the technological parameter of its production is: 1) Jiao Zhu aluminium liquid contains aluminium more than 99.65%, and impurity content is not more than 0.35%, and Fe/Si ratio is controlled between 1.2～1.5; 2) casting temperature is controlled between 720～730 ℃.3) casting speed is controlled at 80～100mm/min.4) horizontal plane of aluminium liquid upper limb 2.0cm and remaining on this horizontal plane in the crystallizer reduces fluctuation as far as possible.
Embodiment
Please write the concrete title of Casting Equipment, control during casting, the pressure of cooling water is controlled at 0.8～1.0kg/cm
2(pump lift H=32m, flow Q=100m
3/ h).
