Frequently Asked Questions (FAQs)
The assembly is designed to support continuous strand loads that include thermal expansion forces, static strand weight, and dynamic vibration loads. Exact load capacity is determined by roll diameter, bearing selection, and frame stiffness, which can be provided upon request.
The assembly can be produced with either spherical roller bearings or deep groove bearings, depending on the customer requirement. Both options are selected based on temperature rating, radial load capability, and lubrication intervals.
The frame includes precision machined mounting surfaces that fix roll centers within controlled tolerances. Typical alignment accuracy is within one tenth of a millimeter across the roll width, ensuring consistent strand guidance.
Rolls are commonly produced from alloy steel with heat treatment suitable for high wear environments. Frames are fabricated from structural steel plate with stress relief applied after welding to prevent distortion during operation.
Roll surfaces are ground or polished to maintain smooth contact with the hot strand and reduce friction. The finish is typically within an Ra range appropriate for continuous caster requirements.
The bearing housings and frame geometry permit controlled axial float of the roll shaft, preventing excessive thermal loading during high temperature operation.
A centralized automatic lubrication system is recommended for continuous casting lines, supplying consistent lubricant volume to all bearings. Grease type and viscosity depend on temperature range and bearing load.
