Mold Frame / Housing: Maximum Load Capacity 50-200 tons

Q: What is the primary function of the mold frame in continuous casting?

The mold frame provides structural rigidity and precise alignment for the copper mold, ensuring dimensional stability during steel solidification under extreme thermal and mechanical loads.

Q: Why are high-strength materials required for mold frames?

High-strength low-alloy steels are necessary to withstand thermal cycling stresses, ferrostatic pressure from molten steel, and mechanical loads from adjustment mechanisms without permanent deformation.

Q: How does the frame contribute to mold cooling efficiency?

The frame incorporates precisely machined cooling water channels that distribute coolant uniformly around the copper mold, maintaining optimal thermal gradients for controlled solidification.

Component Specifications

Definition

The Mold Frame/Housing is a critical structural component in continuous casting mold assemblies that provides rigid support, precise alignment, and thermal stability for the copper mold. It maintains dimensional accuracy under extreme thermal cycling and mechanical loads during steel solidification, ensuring consistent slab quality and preventing mold distortion.

Working Principle

The frame provides mechanical support to maintain the copper mold's precise geometry during continuous casting. It absorbs thermal expansion stresses from the molten steel contact, facilitates cooling water distribution through integrated channels, and allows for mold width adjustment mechanisms in modern designs. The housing ensures the mold remains perpendicular to the casting direction while withstanding ferrostatic pressure.

Materials

High-strength low-alloy steel (HSLA) grades like ASTM A572 or equivalent, often with stress-relieved heat treatment. Critical surfaces may have wear-resistant coatings. Materials must maintain structural integrity at operating temperatures up to 300°C.
