Non standard customized mechanical parts in steel plants refer to non-standard mechanical spare parts or components tailored to the specific needs and process requirements of the steel plant. These mechanical components usually do not conform to conventional standard dimensions and specifications, but are personalized designed and manufactured based on factors such as the process flow, equipment layout, and production scale of the steel plant. The application of non-standard customized mechanical components is very extensive in steel plants. For example, some special conveying equipment, loading and unloading equipment, smelting equipment, etc. need to be customized according to the actual situation of the steel plant. In addition, some auxiliary equipment in steel plants, such as cranes, pumps, valves, etc., may also require non-standard customization to meet specific process requirements and usage environments. The design and manufacturing of non-standard customized mechanical parts require professional technology and experience. Manufacturers need to fully understand the process flow and production requirements of steel plants, comprehensively consider the working environment, load conditions, and operating speed of equipment, to ensure that customized mechanical components can meet the actual needs of steel plants and have the characteristics of efficiency, stability, and safety.
