The twohalves of the mold are drawn apart as soon as a thin skin isformed, holding the liquid steel during compression. The 3i4 The Iron and Steel Magazine movement of the molds, which are placed close together, ismade by drawbars connected with the head of the hydraulicrams. This apparatus has given very satisfactory results forsmall ingots cast from crucibles, but it is not well adapted forcasting from a bottom-tapped ladle into large molds. A specialapparatus on the same principle was built for this purpose, butthe experiments were not continued sufficiently long to securesuccessful
