Aluminum rods are a type of aluminum product. Aluminum rods can be divided into different types according to the different metal elements they contain.
The melting and casting process of aluminum rods includes six steps: melting, purification, impurity removal, degassing, slag removal and casting. The main melting and casting processes are as follows:
1. First, calculate the amount of various alloy components that need to be added to the aluminum rod according to the specific alloy brand that needs to be produced, and then reasonably match the various raw materials to avoid errors.
2. Then the prepared raw materials are gradually added to the melting furnace for melting according to the process requirements, and the impurities and gases in the melt are removed through refining methods such as degassing and slag removal.
3. The smelted aluminum liquid is cooled and cast into round cast rods of various specifications through the deep well casting system under certain casting process conditions. In this way, various different aluminum rods can be made.
The aluminum rod casting process includes melting, purification, impurity removal, degassing, slag removal and casting processes.
The main process is:
(1) Ingredients:
Based on the specific alloys that need to be produced, calculate the addition amounts of various alloy components and rationally match various raw materials.
(2) Smelting:
Add the prepared raw materials to the melting furnace for melting according to process requirements, and effectively remove impurities and gases in the melt through degassing and slag removal refining methods.
(3) Casting:
The smelted aluminum liquid passes through the deep well casting system under certain casting process conditions and is cooled and cast.
Produce round cast rods of various specifications. The production process of standard extruded aluminum rods. The aluminum rod production line is roughly divided into casting workshop, mold workshop, extrusion workshop (1)/(2), aging workshop, packaging workshop, finished product warehouse, and aluminum bar warehouse.
Casting workshop → Aluminum rod warehouse Extrusion workshop → Aging workshop → Packaging workshop warehouse → Finished product warehouse The following is a focused analysis of the casting workshop, extrusion workshop and aging workshop.
(1) Casting process Casting process
The ultimate goal is to produce aluminum rods that meet the requirements. To produce these aluminum rods, you must go through the process:
Smelting→casting→sawing rods→homogenizing aluminum rods→cooling, washing rods→putting aluminum rods into the warehouse.
1. Smelting process flow in melting and casting workshop:
Load the furnace → Melt → Stir and completely melt → Add scrap → Melt → Add scrap → Completely melt → Spread covering agent and slagging agent → Remove slag → Stir → Sampling and analysis before the furnace → Add Al-Si (Sl-Cu, Cr additives ), Mg ingot → stirring → sampling, post-furnace analysis → composition adjustment → refining → slag removal and covering → let stand
2. Casting
3. Saw material
4. Homogenization of aluminum rods
5. Cooling and washing rods
(2) Extrusion process
Extrusion process:
Preparation before pressing → Extrusion → Stretching and straightening → Sawing into finished product → Frame and trimming
1. Preparation before extrusion
2. Squeeze
3. Stretching and straightening
4. Sawing the finished product, trimming and framing
