Problems solved by technology

The extraction of the sample, e.g. the separation of the sampling chamber from the deacidification chamber is rather complicated with this arrangement, since first the common box has to be destroyed

Embodiment Construction

[0017] The carrier 1 of the sampler consists of two cardboard tubes, one inserted into the other. The submerged end of the carrier 1 is sealed by a measuring head 2 with a sensor 3 located on the outside and surrounded by a typically metal cap 3a. The measuring head inside the carrier 1 is equipped with a blocking element 4 in a recess of which a cylindrical helical spring 5 is fixed. At the end remote from the measuring head, the helical spring 5 presses against the sampling chamber 6 , which has an inflow opening 7 at its bottom end remote from the submerged end of the sampler. Arranged on the inflow opening 7 is a quartz tube 8 which is attached to the sampling chamber 6 in a sealed manner by means of a shaped member 9 . The shaping member 9 is pressed against the inflow area of ​​the sampling chamber 6, and the quartz tube 8 is fixed on the shaping member 9 by refractory cement 9a. Under spring pressure, the forming member 9 is pressed against the end of the deacidificat...

Abstract

A sampler for molten metal has a carrier; in the carrier, a sampling cavity and a deacidification chamber are connected with each other in a seal way through an inflow port and are arrayed in the carrier in succession along the axial direction of the carrier; the deacidification chamber is provided with an inflow pipeline passing through the carrier. The sampler which can easily and reliably assembled is provided, even has relatively large manufacturing tolerance, and allows samples to be easy to separate after sampling; the sampling cavity is kept on the deacidification chamber by an elastic element along the axial direction.

Description

technical field [0001] The invention relates to a sampler for sampling molten metal with a carrier, the sampling cavity and the deacidification chamber are connected in a sealed manner through an inflow port and are successively arranged in the carrier along the axis of the carrier, the deacidification chamber has a inlet pipe. Background technique [0002] Such samplers are known, for example the sampler described in DE 30 00 201 has a carrier in which a sampling chamber is arranged, which is connected via an inflow opening to a deacidification chamber. The deacidification chamber has an inlet duct for the molten metal passing through the side wall of the carrier. The sampling chamber and the deacidification chamber consist of separate housing parts and are fixed in the carrier. Usually the housing parts are fixed in the carrier by means of press-fit parts or are glued together by means of adhesive cement. High-precision individual components need to be sealed in such ca...
