<p>In the continuous casting of copper bar, the bar B emerging from a casting wheel and traveling to a rolling mill, whilst within its hot working temperature range, passes through a cutting device comprising a pair (1) of cutting wheels (2) positioned on opposite sides of the advancing cast bar and rotatably driven about their axes. Each of the rotatably driven cutting wheels (2) has around its circumference a cutting edge which is urged into continuous engagement with an edge of the advancing cast bar B to cut flash material from the bar. The useful life of the cutting wheels (2) is substantially greater than that of fixedly mounted blades hitherto employed for this purpose.</p> |
