Abstract: Disclosed herein is a molten metal sampler with a wrap of corrugated board with flutes which provide vertical channels for conveying and outgasing the gas caused by reaction of the body of a molten metal sampler or immersion thermocouple in the molten metal to above the surface of the metal to prevent splash of the equipment operators. The corrugated board is coated with a refractory cement to protect the corrugated board during immersion to maintain the integrity of the channels.

Abstract: Disclosed herein is a molten metal sampler made from cast mold halves which are preassembled in a paperboard sleeve which is filled with sand-resin mix, which is then baked. The sampler is provided with windows on one sample cavity which are provided with metal plates which form the sides for sample mold and provide smooth sides for the sample. Various thickness plates can be employed to fit within the windows. The sampler is also provided with a bath thermocouple and a liquidus arrest thermocouple. The sample formed has a thick disc portion suitable for spectrographic analysis and a wafer portion suitable for punching for gas analysis.

Abstract: A molten metal sampler for obtaining pin samples has mold halves formed from foundry sand with fused quartz tubes located in mold recesses to form the samples. Passages are provided for side filling and end fillings and a bath heat sensor can also be employed.

Abstract: A molten metal sampler is disclosed which includes a mold cavity defined by a steel sleeve having an accurately machined and polished interior surface and a steel disc defining one end of the sampler remote from the sample entry passage by a steel disc having a projecting bolt which becomes imbedded in the sample as it cools and in which the steel disc provides a laterally extending annular flange on the sample so that it can be suspended from a collar for a jominey test. The sleeve and integrally formed flange eliminate the need to machine the sample to prepare it for testing.

Abstract: An apparatus for taking samples of molten metal and having provision for a sample tagging member. The preferred embodiment comprises a sampler including a plurality of separable mold forming elements which cooperate to form a mold chamber. The mold forming elements are mounted within a generally cylindrical housing around which is telescoped a second generally cylindrical member. The mold forming elements are provided with an opening through which a sample tagging member may be placed and the sample tagging member is bent up and around the outside of the first housing and is secured into position frictionally by being overlaid by the second generally cylindrical member telescoped about the first housing.

Abstract: The specification and drawings disclose an apparatus for taking samples of molten metal. The preferred embodiment comprises a housing enclosing a body defining a material flow path and a sample chamber. The material flow path and chamber are configured such that when the device is oriented in its position of use the material flowing into the flow path enters the housing and body from a position on a plane at about the top of said mold chamber, courses through the flow path to a position below said chamber and enters said chamber from said lower area. The body further comprises a conduit extending upwardly from said chamber and exiting the body at its top into a slag and shrink chamber.

Abstract: The specification and drawings disclose an embodiment of an apparatus for taking samples from a flowing stream of molten metal. The apparatus comprises a container defining a sample mold cavity having a flat mold sample chamber and a pin sample chamber that are interconnected. The apparatus is so designed that a sample tube communicating with the mold cavity can be placed in the stream of molten metal to fill the cavity with a quantity of sample metal. The apparatus is externally ribbed to facilitate slidable housing in a suitable protective shield so that the sample tube may be selectively exposed for use in drawing a sample. The sample tube, mold sample chamber and pin sample chamber define a flow path which creates a turbulent flow of molten metal in the sample chambers thereby to equalize the carbon content of the sample metal in both the pin sample and mold sample chambers.
