Existing problem of friction pulley type length measuring unit for continuous caster flame cutting machine has been analyzed,and pinion and rack type length measuring unit has replaced the friction pulley type length measuring unit,good effect has been proved by production practice.

This paper introduces the NC system of a flame cutting machine based on the industry personal computer and the stepping motor.

The numerical control flame cutters are applied in steel plate cutting and the welding industry in extremely widely.

The paper analyzed the main problems of the flame cutter at Panchen Steel,introduced the countermeasures and brought benefits of caster revamping.

Development of NC system for NC flame cutting machine based on PMAC;
