Screwdown Mechanism Mounting Pad: Load Capacity ≥5000 kN

Component Specifications

Definition

A specialized mounting pad that provides a stable, precisely aligned foundation for screwdown mechanisms in rolling mill stand housings. It ensures proper load distribution, maintains alignment under operational stresses, and facilitates accurate vertical positioning of work rolls during metal forming processes.

Working Principle

Acts as a rigid interface between the screwdown mechanism and the mill housing, transmitting compressive forces while maintaining geometric stability. It distributes operational loads evenly to prevent localized stress concentrations and ensures the screwdown mechanism maintains precise vertical alignment during rolling operations.

Materials

High-strength alloy steel (typically ASTM A36 or equivalent), heat-treated to 250-300 HB hardness, with machined surfaces ground to precise flatness specifications
