Process Performance Requirements To Be Met In Manufacturing Basket Mould

The Basket Mould manufacturing process usually involves several processes, such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce production costs, the material should have good forge ability, machinability, hardenability, hardenability, and grindability. It should also have small oxidation, decarburization sensitivity, quenching, deformation cracking tendency.

1. Malleability

It has low hot forging deformation resistance, good plasticity, wide forging temperature range, lower forging cracks, and net carbide precipitation tendency.

2. Annealing processability

The spheroidizing annealing temperature range is wide, the annealing hardness is low, the fluctuation range is small, and the spheroidizing rate is high.

3. Machinability

Large cutting volume, low tool loss, and low surface roughness.

4. Sensitivity to oxidation and decarburization

When heated at a high temperature, the oxidation resistance is good, the decarburization speed is slow, and it is not sensitive to the heating medium, and the tendency of pitting corrosion is small.

5. Hardenability

Uniform and high surface hardness after quenching.

6. Hardenability

After quenching, a deep hardened layer can be obtained, which can be hardened with a mild quenching medium.

7. The tendency of quenching deformation and cracking

Conventional quenching has little change, shape warping, small deformation, and a low tendency of abnormal deformation. Conventional quenching has low sensitivity to cracks and is insensitive to quenching temperature and workpiece shape.

8. Grindability

The relative wear of the grinding wheel is small, the maximum grinding amount is not burnt, and it is not sensitive to the quality of the grinding wheel and cooling conditions, and it is not easy to cause wear and cracks of the grinding wheel.
