Problems solved by technology

[0007] In known sampling devices, the sample is removed from the sample chamber immediately after the carrier tube is removed from the metal melt, whereby the immersion end of the carrier tube and the sample chamber itself are destroyed simultaneously with the release of the sample disposed in the sample chamber

Embodiment Construction

[0046] figure 1 A cutaway view of the submerged end of the sampling device is shown. The input pipe 2 and the thermal sensor 3 of the molten metal sample are exposed at the immersion end of the carrying pipe 1 . The metal cap 4 protects the input pipe 2 . The metal cap 4 and the outer protective cap 5 made of metal prevent the inlet pipe 2 from being damaged during conveyance and prevent the inlet pipe 2 from immersing in the metal melt (e.g. steel melt) when the sampling device passes through the slag layer Afterwards, but before the opening of the inlet tube 2 is exposed, it is damaged. The thermosensitive element 3 and the input pipe 2 are fixed on the heat-resistant body 6 . The inlet pipe 2 leads into the cooling body 7 , and the molten metal passes through the passage opening 8 of the cooling body into the sample chamber 9 . The upper side of the sample chamber (viewed in the immersion direction) is closed off by an upper cooling body 10 . The cooling bodies 7, 10 c...

Abstract

A sampler is provided for taking samples from melts having a melting point higher than 600 DEG C., in particular for metal or cryolite melts. The sampler includes a carrier tube having an immersion end and having a sample chamber assembly arranged on the immersion end of the carrier tube. The assembly has an inlet opening and a sample cavity for the melt and is arranged at least partly inside the carrier tube. The sample chamber assembly has on a part of its outer surface a coupling device, arranged inside the carrier tube, for coupling a carrier lance. A method is also provided for taking samples using such a sampler.

Description

technical field [0001] The present invention relates to a sampling device for sampling from melts with a melting point higher than 600°C, especially a sampling device for sampling from metal or cryolite melts (especially iron or steel melts) using a carrier tube, wherein the carrier tube has a submerged end and a sample chamber assembly disposed on the immersion end of the carrier tube, the sample cell assembly having an inlet port and a melt sample cavity, and at least partially disposed inside the carrier tube. In addition, the present invention also relates to a sample chamber assembly of such a sampling device and a method of sampling using such a sampling device. Background technique [0002] Various sampling devices for melts, in particular metal or cryolite melts, are known. For example, DE 32 33 677 C1 describes a metal and slag sampling device. Wherein, an inlet of the sample cavity is provided at the immersion end of the carrying tube, and the inlet is covered by...
