Negative Strip Time Calculator for Continuous Casting Machine

The negative strip of continuous casting machine plays a vital role while casting quality steel. Negative strip of machine is referred to the amount of time the mould is in downward direction when the mould speed is greater than casting speed.

Formulas:

Negative Strip Time (Ns) = (Vc - Vm) / Vc

Mould Oscillation Speed (Vm) = 2 × f × l

Where:

• Vc = Casting speed (mtr/min)
• Vm = Mould oscillation speed (cycles/min)
• f = Frequency at casting speed in cycles/min
• l = Length of stroke
