1
Preparation of raw materials - including visual inspection of raw materials, chemical composition analysis, ingredients and weighing of various ingredients according to the calculation of ingredients. In addition, also includes refining agent, metamorphic agent drying and weighing.
2
Smelting - adding materials in a furnace in a certain order to melt them into alloys of uniform chemical composition.
3. Pre-furnace test -- after the alloy is evenly melted, sample and test to check whether various chemical components meet technical standards.
4
Adjustment of composition - If the chemical composition of one or more alloys is found to exceed the technical standard after testing, adjustment shall be made to make the chemical composition meet the technical standard.
5
Refining - After chemical composition requirements, a refining agent is used to remove dissolved gases and entrained solid particles from the alloy.
6
Refining metamorphism - adding appropriate refiner and modifier to aluminum alloy liquid to improve mechanical properties and mechanical cutting properties of the alloy, etc.
7
Casting -- casting aluminum alloy with qualified chemical composition, good metamorphism effect, gas content and slag content to meet the requirements into ingot, into bales.
