A sampler for taking samples from a molten metal bath includes a carrier tube having an immersion end; sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening; an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, and the opening is configured to receive the molten metal from the inflow conduit; a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; and a metal bushing, wherein the metal bushing coupling the inflow conduit to the sample chamber.

Molten metal samplers for high and low oxygen applications

The present invention relates to a sampler for taking samples from a molten metal bath, particularly a molten steel bath, the sampler comprising: a carrier tube having an immersion end; a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening; an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, wherein the opening is configured to receive the molten metal from the inflow conduit; a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; and a de-oxidant material arranged along a central axis of the inflow conduit, wherein at least part of the de-oxidant material is arranged near the second end of the inflow conduit inside the measuring head, and wherein the inflow conduit comprises first coupling means, arranged on the second end of the inflow conduit, wherein the de-oxidant material comprises second coupling means, to interact with the first coupling means on the inflow conduit to anchor the de-oxidant material in a position along the central axis of the inflow conduit. The invention also relates to a sampler for taking samples from a molten metal bath, particularly a molten steel bath, the sampler comprising:a carrier tube having an immersion end;a sample chamber assembly arranged on the immersion end of the carrier tube, the sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening;an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, wherein the opening is configured to receive the molten metal from the inflow conduit;a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; anda metal bushing, wherein the metal bushing coupling the inflow conduit to the sample chamber.

A sampling device for molten metals is provided having a carrier tube and a sample chamber fixed in the carrier tube, with an inlet piece for the molten metal flowing into the sample chamber. In the inlet piece there is arranged an inlet tube, which has an outlet into the sample chamber and an inlet opening at its other end. The outlet as well as the inlet opening of the inlet tube has a reduced cross section relative to the central part of the inlet tube. The inlet tube is formed of quartz glass, and the wall of the inlet tube is crimped toward the axis of the inlet tube at its two ends.

Sampling device

A sampler is provided for melts, in particular for slags lying on a molten metal, the sampler having a single- or multi-part body for arrangement in a support. The sampler has an inlet and a sample chamber with two opposing chamber walls, wherein an inlet opening is arranged in one chamber wall. In order to make possible homogeneous and stable samples, an intermediate plate with at least one through opening is arranged inside of the sample chamber spaced from the chamber walls.

Sampler for melts, in particular for slags lying on a molten metal

A measuring device for determining the oxygen activity in metal melts or slag melts has a measuring head arranged on the end of a carrier tube, on which head an electrochemical measuring cell is arranged. The electrochemical measuring cell has a solid electrolyte tube closed on one end, which is surrounded on the closed end and at least on a portion of its periphery by a steel tube closed on one end. A reference material and a filler material adjoining the reference material are arranged inside the solid electrolyte tube on its closed end. A metal rod is arranged as an electrode along the solid electrolyte tube in such a manner that, on the one hand, it stands in contact with the reference material and, on the other hand, it projects out of the open end of the solid electrolyte tube. The open end of the solid electrolyte tube has a closure which is constructed as a cap, which fits on the exterior of the steel tube or the solid electrolyte tube, and the closure is gas-permeable.

Measuring device for determining the oxygen activity in metal melts or slag melts

A sampling device for molten metals, especially for molten cast iron or pig iron, has a sampling chamber arranged in a refractory body mounted on a carrier. The sampling chamber is bounded on two opposing walls by one metal plate each, and has at least one inlet opening for molten metal on a further wall. In order to create a sampling device with which samples are obtained which have the best possible white solidification and at the same time have the sturdiness necessary for an automatic sample analysis, a metal disk is separably arranged in the interior of the sampling chamber on at least one of the two metal plates. The diameter of metal disk is smaller than the diameter of the sampling chamber, and the thickness of the disk is less than the thickness of the sampling chamber.
