High-Strength Cast Steel Rolling Mill Housings (Mill Stands)
Product Description
Yile Machinery is a specialized manufacturer of high-strength cast steel rolling mill housings, the foundational component of any hot or cold rolling mill. These massive structures form the backbone of the mill stand, providing the rigidity and precision required to produce high-quality steel products.
We leverage advanced casting technology and large-scale precision machining to produce mill housings that meet the extreme demands of modern steel production.
The Critical Role of the Mill Housing
The rolling mill housing is the single most important structural element in a rolling mill. Its performance directly impacts mill productivity, uptime, and the final product quality. A high-quality housing must:
Withstand Immense Rolling Forces: Absorb the millions of cycles of immense force and vibration generated during the rolling process without deflection or fatigue.
Ensure Geometric Precision: Maintain the precise alignment of the rolls, chocks, and screw-down systems to guarantee accurate and consistent steel thickness.
Provide Extreme Durability: Offer a long service life in the harsh, high-temperature environment of a steel mill.
Superior Materials and Advanced Casting Process
The strength of a mill housing begins with the material. We manufacture housings from high-strength alloy steels engineered for toughness and fatigue resistance.
Premium Alloy Steels: We commonly use materials like 34CrMo4 (1.7220), ZG45, and ZG35CrMo, selected for their excellent mechanical properties after heat treatment.
Advanced Casting Simulation: Before pouring, we use simulation software (CAE) to optimize the casting process, ensuring a sound, defect-free casting with high internal integrity.
Specialized Heat Treatment: After casting, the housings undergo a multi-stage heat treatment process (such as Quenching & Tempering) to achieve the optimal balance of hardness, strength, and toughness required for the application.
Precision Machining for Perfect Assembly
A raw casting becomes a functional mill housing in our precision machining facility. Using large-scale CNC gantry milling machines and boring centers, we machine all critical features to exact tolerances specified in your drawings.
Machining of Mill "Windows" for roll chock assembly.
Milling of top and bottom mounting surfaces.
Boring and drilling for drive systems, screw-down mechanisms, and hydraulic cylinders.
