How to solve the problem of industrial aluminum hardness is too low
ã€China Aluminum Industry Network】When manufacturing and processing industrial aluminum profiles, how to control the hardness is the key. If there is a slight failure, it will cause problems for users. Now share the following methods.
Silicon Carbide particle size sand.
It is also known as silicon carbide sand,generally divided into mesh grade sand from 8#-320#,the greater the number is,the smaller particle size it is.
The size over 320# generally referred as the silicon carbide micro powder.Silicon carbide particle size of sand is dvided into green and black.
It is the ideal for abrasive material,mainly used in polishing and grinding wheel,cutting slices,and etc sectors in abrasive industry.

1, aluminum extrusion frame can not be too dense, there must be space between the material and material, especially non-ventilated small material, thick material spacing should be larger, when the tube material and small material, sheet material when a frame , The tube is placed below this is conducive to aging circulation.
2. Temperature setting and control: Usually, there is a certain error between the temperature and the apparent temperature. When setting the temperature of the table, set the temperature according to the actual temperature of the furnace and pay close attention to the temperature fluctuation.
3, aluminum aging insulation: to strictly in accordance with the process requirements for aging, the insulation time should be appropriate to prevent the lack of timeliness or aging and resulting in insufficient hardness.
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.
