摘要： A device for contactless, vertically downwards continuous casting of metals in an electromagnetic alternating field, has an inductor and an electrically conductive, non-ferromagnetic screen that tapers downwards and features at a vertical distance 9 from this screen an electrically conductive, non-ferromagnetic counter screen that tapers upwards, the distance 9 between the said screen and counter screen being at least 2 mm, at most equal of the height of the inductor and in a continuous process which employs this device the circulation of the melt in the molten head of the ingot is reduced at least in the steady-state phase of casting. The process is particularly suitable for continuous casting aluminum alloys having a magnesium content of at least 2%.

摘要： A continuously cast strand or ingot of metal is cooled as it emerges from the mold by applying a coolant directly to the surface of the strand. In order to prevent distortion at the foot of the ingot due to too abrupt cooling, polymers of molecular weight 10.sup.4 -10.sup.8 are added to the coolant at least during the initial phase of casting. By the addition of polymers to the coolant the kinetics of formation and discharge of vapor bubbles as the coolant strikes the ingot surface are significantly altered due to the reduction in the surface tension of the coolant; as a result of this an insulating film of coolant vapor forms on the surface of the ingot thus reducing the heat flow from the ingot.

摘要： The cooling of a continuously cast ingot of metal as it emerges from the mold is carried out by applying coolant directly to the ingot surface. In order to reduce the amount of curvature at the foot of the ingot due to too rapid cooling, a substance which releases a gas as a product of decomposition on striking the hot ingot surface is added to the coolant at least during the initial phase of casting. This gas forms an insulating film on the ingot surface thus reducing the rate of heat extraction. Particularly suitable for this purpose are substances which produce carbon dioxide or nitrogen as decomposition product.
摘要翻译：连续铸造的金属锭从模具出来时的冷却通过将冷却剂直接施加到锭表面来进行。为了减少由于太快的冷却而在锭的脚部处的曲率的量，至少在铸造的初始阶段将至少作为分解产物的气体作为冲击热锭表面的物质添加到冷却剂中。这种气体在铸锭表面上形成绝缘膜，从而降低了热提取速率。特别适合于此目的的是产生二氧化碳或氮气作为分解产物的物质。
