Disclosed is apparatus and method for integrated, continuous, high speed manufacture of metallic strip, especially brass, from a melt. The apparatus comprises a chilled casting mold in liquid communication with a melt and means for drawing a rod through the mold in a pattern of forward and reverse strokes. After emergence from the mold, the rod speed is regulated to a substantially constant value before conversion into strip. In this embodiment, the casting mold is stationary; the rod is drawn through the mold by driven rolls programmed to create the desired forward and reverse motion of the rod through the mold. Creating substantially constant speed is accomplished by allowing slack to develop through the lateral deflection of the rod. In another embodiment, the casting mold oscillates as the rod is withdrawn at a substantially constant speed so further rod motion regulation is unnecessary. Conversion of the rod to strip comprises flattening in a hot rolling mill, and quenching. In accordance with known procedures the produced strip can be further reduced in cross section in a cold rolling mill if desired. |
