After the surface of industrial LED light aluminum profile are oxidized, the appearance will look very beautiful, and it is resistant to dirt. It is easy to clean with oil stains. When assembling into products, we can use different specifications of aluminum profiles based on different loads. , Xiaobian will introduce how to ensure that industrial aluminum profiles can reach the hardness used.

Furnace charge processing, the charge needs to be preheated before entering the furnace, this can remove the moisture attached to the surface, and shorten our smelting time. Preparation of crucibles and melting tools. New crucibles should be cleaned and carefully inspected for penetrating defects.

Confirm that there are no defects before they can be used. Preheat to dark red to burn off the moisture and combustible substances attached to the inner wall of the crucible. After cooling, carefully clean the inner wall of the crucible. When the temperature is not lower than 200 degrees, spray the paint and dry it before use.

The melting temperature is controlled, the alloy liquid is quickly raised to a higher temperature, and reasonable stirring is performed to promote the dissolution of all alloy elements. After confirming that all the elements are dissolved, the refining and degassing is performed, and the scum is removed to the pouring temperature.

In order to control the melting time, in order to reduce the oxidation and gettering of the aluminum profile solution, we need to reduce the time that the aluminum solution stays in the furnace as much as possible, and we need to achieve rapid melting. In order to speed up the smelting process, we first need to add medium bulk and low melting point regrind, which is convenient to form a molten pool at the bottom of the crucible, and then add an aluminum ingot to gradually expand the molten pool and accelerate the melting.
