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

摘要

"Measuring device for determining the oxygen activity in metal or slag fusion in fusion".The invention relates to a measuring device for determining the oxygen activity in metal or slag fusion in fusion with a measuring head.Prepared in one end of a tube holder, in which it is prepared an analysis cell electrochemistry, the electrochemical cell analysis presents a tube of solid electrolyte.Closed on one side, which in the closed end and at least a portion of its circumference is surrounded by a steel tube, closed at one side.And inside the tube of solid electrolyte in its closed end is provided a reference material and the way adjacent to the reference material, a filling material.And a metal stick is prepared as the electrode along the tube of solid electrolyte, inside this in such a way,This is in contact on the one hand with reference material and on the other side is projected from the open end of the tube of solid electrolyte to outside.And with the open end of the tube of solid electrolyte has a zipper.The measuring device is distinguished by the fact that the closure is configured as a cap, which abuts the outer side of the steel pipe or tube of solid electrolyte.And that the fastener is permeable to gases.
