CCM Negative Strip & Mould Oscillation Calculator
Calculate the negative-strip interval for sinusoidal mould motion using consistent SI units and a full peak-to-peak stroke.
This tool provides a preliminary engineering calculation for reference. Final equipment selection, design and commissioning decisions must consider manufacturer data, applicable standards, operating conditions and project-specific engineering requirements. It is not certified design output.

Formula
f(Hz) = frequency(CPM) / 60
x(t) = (S/2) sin(2πft)
vm,max = π f S
tN = [1/(πf)] cos⁻¹[vc/(πfS)]
Worked example
6 mm full stroke, 180 cpm and 1.2 m/min casting speed.
Expected check: Maximum mould velocity = 3.393; Negative-strip interval per oscillation cycle = 0.1283; Negative-strip fraction = 38.5.
Assumptions
- • Sinusoidal mould motion only
- • S is full peak-to-peak stroke
- • Casting speed (m/min) and mould speed (m/s) are normalized internally before comparison
- • Frequency conversion from cycles per minute (CPM) to hertz is explicit
- • Casting speed is constant through one cycle
Limitations
- • Result is the negative-strip interval per oscillation cycle
- • Does not support or imply a correction factor for non-sinusoidal waveforms, hydraulic/servo tracking error or waveform asymmetry
- • Does not set metallurgical oscillation practice
Frequently asked questions
Can this result be used for final equipment selection?
No. Use it for a preliminary check, then verify manufacturer data, site conditions, applicable standards and the complete system design.
What does formula version 1.0.0 mean?
It identifies the exact calculation logic used so a saved result can be traced when the formula register changes.
Can Elexorn review my calculation?
Yes. Transfer the result to Request a Quote or Talk to an Elexorn Engineer and add the relevant project or equipment details.
