Low-carbon Optimization steps for characteristic parameters of Sand casting process Design

According to the above-mentioned parameter optimization objective function, and combined with the characteristic carbon benefit calculation model of process design, the characteristic parameters of sand casting process design are optimized with low carbon. The specific optimization steps are as follows:

Step 1: selection and value of process parameters associated with features.

Firstly, according to the characteristics of sand casting process design, the relevant process parameters are extracted as the optimization object, and combined with the casting production conditions and casting structure, the initial values of the related process parameters are determined by the look-up table method.

Step 2: formulation and quality verification of the original casting process plan.

The original casting process plan is made according to the initial values of the related process parameters, and the pouring simulation of the example is carried out by using ProCAST software, and the total shrinkage porosity and porosity are taken as quality constraints to verify the feasibility of the process plan.

Step 3: carbon benefit calculation and result analysis.

For the casting process scheme that meets the quality constraints, combined with the input of materials, energy and production time in the casting process, the process carbon benefit is calculated, and the results are analyzed and compared.

Step 4: determination of casting optimization process plan.

The related process parameters are re-valued, and the casting process plan is determined by using the parameter optimization objective function as the constraint condition, and step 2 is repeated. All the process parameters are compared and analyzed, and the process parameters with the best carbon benefit are taken as the casting optimization process plan.
