How Does Steel Foundry Choose the Production Process

The method of formulating the model, modeling and core making of large-scale cast steel: the solid wood type is used as the solid wood type of the operating side frame. The wood surface layer is combined with steel, wood and soil to achieve the forming of the inner core box of the frame, meet the shape requirements, and save wood and time. Both the medium sand and the core material in the steel casting process are very important. In order to make the quality of the frame meet the requirements, the resin is used as the mold and core sand. It can not only ensure the quality requirements of sand mold and sand core, but also improve productivity.

Determination of large cast steel outlets: Combined with the structure of the operating side frame, the open outlet is used to achieve a higher shrinkage effect. In order to ensure the quality requirements of the steel casting process, external cooling iron is added to the riser surface, and the solidification sequence of the casting is also designed to ensure the quality requirements of the casting. Large-scale cast steel sets up a gating system: according to the design principle, the liquid metal can rise steadily in the mold. Resin sand is poured quickly without high temperature baking. The flow rate at the time of pouring should be increased in time.
