The casting process is a crucial manufacturing method utilized in numerous sectors to create intricate components and forms. However, there are a number of underlying causes of casting flaws that can result in subpar quality, higher costs, and decreased productivity. This review seeks to give a general overview of casting process flaws, their causes, and possible fixes. The evaluation will go over the various possible flaws, including porosity, shrinkage, and surface abnormalities, as well as their underlying causes, which include design, material, and process characteristics. Furthermore, the review will focus on various remedial measures that can be taken to overcome these defects and improve casting quality, such as changes in design, material selection, and process optimization. This review will be useful for researchers and practitioners in the casting industry who are interested in improving their understanding of casting defects and developing effective remedial measures to enhance product quality and efficiency.

The present paper is focused on the mathematical and graphical determination of temperature and thermal parameters depending on the heat dissipation from solidifying steel in the mould, respectively in the primary cooling zone of continuous casting of steel (CCS). The main task of the primary cooling is mainly to remove heat from the solidifying steel, therefore knowledge of the temperature fields in the precast and mould is important. As part of the present research to evaluate the thermal performance of the mould, the heat flux density dependencies q between the steel and the cooling water in the mould were expressed in the primary cooling region. The cooling water parameters and temperature gradients along the height and perimeter of the working surface of a copper mould insert of square cross-section of 150 x 150 mm and 1 m long were used to determine the heat removal rate from the solidifying steel. The temperature and thermal parameters were determined for the solidification and precooling tasks for two grades of steel with carbon contents of 0.18 wt.% and 0.83 wt.%. Casting speeds were chosen to range from 2.1 m•min -1 to 2.7 m•min -1 and casting temperatures from 1500 °C to 1550 °C. The obtained dependencies were used for numerical simulation in the ProCAST environment.

The permanent mold was made of Ferro Casting Ductile as a result of sand casting. Permanent mold is mold that can be used repeatedly. This permanent mold is used to produce tensile test specimens. Tensile test specimens are made of gray cast iron. This study aims to determine and analyze the effect of spheroidal graphite on the hardness and toughness of Ferro Casting Ductile in permanent molds to make tensile test specimens. The casting process starts by making patterns using Styrofoam, making molds with green-sand sand molds, followed by pouring molten cast iron into the molds. The next process is dismantling the castings and machining to get a permanent mold according to the dimensions. Specimens for testing the chemical composition were obtained from the results of castings into spherical dies. Meanwhile, the impact, hardness, and microstructure specimens were taken from the permanent molded product. The results of the chemical composition test showed that Ferro Casting Ductile contained several main elements, namely 92.14 %Fe, 3.681 %C, 3.715 %Si, 0.182 %Mn, 0.050 %Ni, and 0.034 %Mg which affected the percentage of nodular graphite. Nodular graphite will affect the hardness of the permanent mold. Validation was carried out by testing the hardness at 3 different points 167.70 VHN, 162.77 VHN, and 155.77 VHN. Toughness was obtained from the impact test using the Charpy method, the impact values were 0.048 Joule/mm2 0.046 Joule/mm2 0.037 Joule/mm2 on 3 different specimens. From the test results, the specimen has met the FCD 400 standard.
