How To Cast Accurate Aluminum Ingots?

T-type ingot sow mold can be applied to metal smelting and recycling. Because of its T-type design, it is easy to stack and re-process, and is the best choice for large-scale production in aluminum plants.

◎ Generally, excellent heat-resistant steel or cast iron is used to ensure the service life of the mold.

◎ T-type design is more conducive to storage and transportation

◎ It can be cooled quickly, and the aluminum ingot made has unity

◎ The surface is specially treated or coated to prevent aluminum from sticking to the wall and easy to demoulding.

◎ There are different specifications to choose from, such as 7kgs, 500kgs...

1. Preparation of raw materials: Before metal smelting, aluminum waste should be pre-treated to ensure that the purity of aluminum is not affected by impurities.

2. The use of flux in the melting process helps to remove oxides and impurities in the aluminum liquid to ensure the quality of aluminum ingots

3. Using melting furnaces, reverberatory furnaces and other equipment to melt, can effectively maintain accurate temperature control, usually 660-750 ° C, to avoid oxidation.

4. Preparation of T-type ingot sow mold

◇ sow mold should be preheated to 200-300℃ to prevent thermal shock

◇ Release agent can be used to prevent aluminum sticking to the wall

◇ Clean up in time after use, and check whether there are cracks affecting the ingot

5. Poured aluminum

◇ Pour the aluminum liquid slowly at a controlled speed to prevent turbulence and non-uniformity

◇ Precise pouring can be done by tilting furnace

◇ To ensure that the filling is uniform, to avoid shrinkage holes, or surface defects and other problems

◇ Maintain a consistent pouring temperature (700-720°C) to avoid poor surface finish

6. Cool and set

◇ Natural cooling: It can be cooled naturally at room temperature to make the structure uniform

◇ Water cooling: water spraying can be used to accelerate cooling, but it must be controlled in this process, otherwise cracks and other situations will occur

◇ Cooling time usually takes several hours to fully set

7. Release mold

◇ After complete solidification, the ingot can be removed from the mold (the mold can be removed by hydraulic lift and other equipment)

◇ Check the surface, pores and cracks of aluminum ingots

8. Safe handling, stacking and transportation

The use of T-type ingot sow mold can accurately cast standard, unified aluminum ingots, and can be effectively stored and remanufactured, but it is necessary to control each step of the smelting process, from the selection of raw materials to the release of the mold need to do the preliminary preparation work, otherwise it will affect the quality of aluminum ingots, affect the quality of the final product.
