Process paper on lost foam casting iron cap for high voltage wire

Insulating iron caps for high-voltage wires were originally produced by coated sand casting. With the advantages of lost foam casting in terms of material labor cost and environmental protection of operating energy, people began to try to use lost foam casting to produce such castings. This paper describes a variety of lost foam production iron cap casting process practice, so as to explore the most suitable for lost foam production casting process.

Influence of Lost Foram Equipment on Lost Foram Process

The lost vanity mold process equipment is a necessary condition to ensure the implementation of the lost vanity mold process, and it also affects the quality of castings to varying degrees. Among them, the quality of the white mold, the pouring process and the sand treatment play a very important role in the whole process of the lost-form process. This paper mainly stands in the perspective of the process to the above-mentioned process of the loss of the key equipment for a concise analysis, the purpose is to clarify how to ensure the smooth implementation of the process.

Process Control of the Motor Shell Lost Molding

Before the Fujian site, the motor case was produced by the tide mold sand process, which has low production efficiency and high labor intensity, poor product appearance quality and heavy cleaning workload. With the promotion and wide application of the lost vanishing mold process [1], the factory introduced the lost vanishing mold process to produce the motor shell. Due to the limitation of technology and other convenience, the surface continuity of the mechanism white mold is poor, the surface quality of the cast castings is not good, and there are defects such as slag inclusion, sand addition, cold isolation, deformation, etc. Entrusted by the factory, we are here to provide technical guidance and services, from raw materials advance, white mold drying, brushing and drying, group molding process to buried box modeling and pouring to strictly control, to solve the problem of disappearance.

Optimization of lost foam casting process for grate bar

The reasons for the low production efficiency and high rejection rate of the lost foam casting of the ZGCr20Mn14Si2N material grate bar are analyzed. By optimizing the original process, the defects of slag and sand inclusion in the casting were solved, and the production efficiency was improved and the production cost was reduced.

Blast furnace cooling stave casting paper

The cooling stave is an important component in the cooling system of the blast furnace. It is installed in the furnace body, furnace waist, furnace belly, furnace cylinder and other parts of the blast furnace. It has the important functions of supporting refractory materials, cooling the furnace shell, and maintaining a reasonable furnace shape. The cooling stave not only bears high temperature, but also bears the abrasion of the furnace charge, the erosion of molten slag and the scouring of gas flow, must have good thermal strength, thermal shock resistance, resistance to quenching heat and other comprehensive performance.
