Industrial aluminum production and processing, how to control the hardness is the key, a slight failure, it will bring trouble to the user, then how to solve the industrial aluminum extrusion hardness is too low?
1. The setting and control of the aluminum aging furnace temperature: Generally, there is a certain error between the aging furnace temperature and the apparent temperature of the aging furnace. When setting the table temperature, the actual temperature of the furnace must be set according to the actual temperature of the furnace. The market pays close attention to the fluctuation of aging furnace temperature.
2, aluminum aging insulation: to strictly follow the process requirements for aging, the insulation time should be appropriate to prevent the lack of timeliness or overtime and resulting in insufficient hardness.
3, aluminum extrusion frame can not be too dense, there must be a gap between the material and material, especially the non-ventilated small material, thick material spacing should be larger, when the tube and the small material, the sheet together when a box , The tube is placed below this is conducive to aging circulation air.
4, before loading the aluminum profile 6xxx other special alloys and ordinary 6063 alloy separately loading furnace aging, due to production reasons must be with the furnace aging, to take special alloy technology to aging.
Aluminum surface treatment is to improve performance, specific methods we must be familiar with, in order to correctly operate, then common aluminum surface treatment methods are divided into several types?
1, metal plating method: more common, while polished after the plating process. The
2. Oxidation (coloring): The purpose of aluminum surface treatment oxidation is divided into two aspects, to enhance physical properties, can achieve the purpose of coloring. The
3, rub lines: There is called drawing, the performance is similar to the car lines, are smooth lines of continuous surface texture, the difference is that the car lines show a circular pattern, rubbing lines show a straight line of flowers. The
4. Sandblasting: The purpose of aluminum surface treatment is to overcome and cover up some defects in the aluminum alloy machining process and meet the customers' special requirements for the appearance of the product. There are glass sand, tungsten sand, etc., showing a different feeling, similar to the rough texture of the frosted glass, fine sand can also show high-end products. The
5, polishing: to overcome defects and deburring the surface of the role of light. The
6, car lines: aluminum surface treatment is the processing of the mold after the re-processing method, the use of lathe processing aluminum hard to talk about common aluminum surface treatment methods in life lines, the overall performance of extremely regular texture features.
