Abstract
The invention involves providing various forms of connectors attachable to a lance for detachably connecting molten metal samplers or devices thereto. More particularly, the purpose of the invention is to provide a safe and simple method whereby a cast sample for example, through use of an improved connector, may be obtained from a flowing metal stream when molten metal is being transferred by pouring from one type vessel to another. The sample may be used directly for spectographic analysis or can be drilled to provide a sample for wet chemical analysis. In addition, the sample may be sawed and polished for use in metallographic study of grain structure, cleanliness, etc. The entire sample can be cast in a two piece mold assembly or device made of a material with optimum cooling venting and dimensional characteristics.
