In addition, the present invention relates to a measurement battery for measuring electrochemical activity. Often, not only the measurement in the molten bath, but also the measurement in the layer above the molten bath is required. The oxygen potential of the slag ^ is evaluated for the metallurgical process. It may also be measured during aluminum electrolysis. The ice rabbit stone is melted so that the metallurgical method can be monitored. — From Radexrundschau 1 " 〇 page 236_243 Milk measurement is carried out in the slag. Here, a Su-Hua, measuring device is arranged in «. The electrochemical element is a device-a measuring cell with an opposite electrode and an electrochemical element. The electrochemical element is arranged from The reference electrode in the reference material is made in a known manner. This reference material is again surrounded by a small solid electrolyte tube. For example, such a measuring cell It is known from European Patent No. 〇〇〇8 431. It is used to measure the oxygen activity in the molten bath, the battery itself is protected, and the protective cover passes through the layer above it (such as mine). The direct measurement of the oxygen activity in the molten layer on the molten bath, such as ore survey or cryolite, requires the electrochemical element to be placed correctly in the layer to be measured. This layer is usually thin (for example, dipper slag about 0 to 〖5 cm ), So the different arrangement of the electrochemical elements also leads to different measurement results ^ Therefore, measuring the correct arrangement of the battery often requires higher energy and cost consumption, because it is not easy to measure the height of the melted surface. Therefore, positioning requires a probe Long immersion time, so 'for example, it is possible to destroy the counter electrode and measure lead. In addition, the method of analyzing slag was learned, in which the slag sample was taken and the Chinese National Bare Standard (CNS) A4 specification was applied at its 4-paper scale (210x297mm) Too installed-.- (please read the notes on the back before filling in this page) Order Λ 冰 A7 B7 Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention Instructions (2 It is partly analyzed after melting. According to the situation known in the art, the present invention is based on providing a method for measuring electrochemical activity, which provides the correct measurement results with the lowest possible consumption. In addition, the present invention provides a suitable The electrochemical element and the measuring cell used for these measurements. The task of solving the above characterized method according to the present invention is that the measuring cell is immersed in the molten bath through the non-metallic liquid layer, and that the active part of the electrochemical element This layer of material contains a non-metallic liquid layer in that the material is held in the electrochemical element until the electrochemical activity is measured, and in that the measurement is performed after the electrochemical element is immersed in the molten metal in the molten bath. It is known The measuring cell is an arrangement of at least one electrochemical element and a counter electrode, and the counter electrode is arranged next to or away from the electrochemical element. The counter electrode can, for example, be fixed to or become part of the wall of the melting vessel. In this case, of course, the counter electrode is not essentially immersed in the molten bath through the non-metallic liquid layer. In this way, the measurement is carried out in an almost constant environment. It is not necessary to measure the correct placement of the battery, because the molten bath usually has a sufficient height. The temperature distribution in the molten bath is considerably more homogeneous than that of the layer on which the activity is measured, so the temperature fluctuations are neglected for the measurement results compared to known measurement methods. The measurement is carried out in an almost constant environment, so it is possible to obtain reproducible and / or comparable measurement results. In order to improve the accuracy and the proven reproducibility of the measurement, when the insertion end of the measurement cell is passed through the non-metallic liquid layer, the counter electrode is not completely surrounded by this layer of material, and / or this material is at least partially before measurement The electrode is removed from phase 5, so the opposite electrode is in direct contact with the molten bath.

Description of the invention (3) occurred during the retest. It is advantageous to determine the oxygen activity of the material to be measured. The material on the non-metallic layer of the molten bath can, for example, become cryolite for iron melting or aluminum electrolysis. Solve the task of measuring the electrochemical activity of the non-metallic layer arranged on the molten bath of the electrochemical element of the bracket of the battery measuring tool. The battery contains a small solid electrolyte tube with an active part and a counter electrode, which lies in the electrochemical element Arranged in the molten bath with the counter electrode, the active part is surrounded by the measured non-metallic layer and at least a part of the counter electrode is in direct contact with the molten bath, ie it is not completely surrounded by the non-metallic layer to be measured. Direct contact with the melt bath relative to the battery produces particularly accurate measurement results. It has proved that making the active part into an annular surface of an electrochemical element is advantageous for correct measurement results. The counter electrode can be protected by painting before use, such as cardboard. When passing the measured layer or entering the molten bath, the protective coating is destroyed and the measured layer is prevented from adhering to the counter electrode. It is more convenient to coat the insertion end of the small solid electrolyte tube with an electrically insulating material without painting the area between the insertion end and the refractory body. For example, 2 〇3 or Mg〇 has been proved to be a particularly suitable coating material ❶ this coating ensures that the material of the layer to be measured is adhered to the electrochemical element, so the electrochemical measurement can be under the rubber melt bath In progress. In essence, the layer material to be measured can adhere to the small solid electrolyte tube in different ways, such as a suitable mechanical collection device for this material, in the form of a tube surrounding the electrochemical element at a certain distance. It is convenient to apply a maximum of 6 mm to the refractory body at the insertion end, especially the coating is about 2.5 mm long. In addition, it has been shown that the electrochemical element protrudes from the main refractory by about 9 to 13 mm, especially about 11 mm.

Description of the invention (4) Adhered to the electrochemical element that will measure the material, and also ensure the reliable measurement of the activity of this material. In addition, it is more convenient to arrange thermal elements in the electrochemical element, because the electrochemical activity is also affected by temperature, and this possible temperature fluctuation can be considered. Solve the task of the electrochemical activity of the non-metallic liquid layer arranged on the melting bath of the electrochemical element of the bracket and the counter electrode of the immersion measuring instrument measuring tool is to protect the non-refractory material when immersed in the non-metallic liquid It is arranged on the opposite electrode, and the electrochemical element does not have a protective layer when immersed in the non-metallic liquid layer. The protective layer of the counter electrode prevents the counter electrode from being covered by slag when flooding through the mine. The protective layer dissolves in the molten bath below it, for example burning or melting. In addition to cardboard, other materials can be used, such as a metal layer with a low melting point, such as copper. When the counter electrode is not covered by slag, the slag can adhere to the surface of the electrochemical element and be inserted into the molten bath because the slag directly reaches the electrochemical element due to the lack of a protective cover or similar direct method. A protective layer or cover, such as cardboard, can be used to protect the electrochemical element from damage during transportation, etc. Remove the protective cover before using the immersion tester gauge, or it will burn due to radiation before insertion. It has been proved that the protective layer is made of cardboard, and the entire opposite electrode surface is preferably covered with the protective layer on the outside of the support. In addition, it is convenient for the electrochemical element to extend out of the holder by about 9 to 13 mm. In an advantageous embodiment of the dip measuring instrument, the holder has a cardboard tube, the measuring head is arranged from the refractory material at its insertion end, and the opposing electrode surrounding the electrochemical element is at least partially ring-shaped, for example, in Pass the measuring head like a metal test tube, and it protrudes in front of it "In addition, the contact of the counter electrode and the contact of the electrochemical element f · Binding ice (please read the note $ item on the back and fill in this page)

Invention Instructions (6). The small solid electrolyte tube 7 of the electrochemical element 1 is coated with an electrically insulating material 8 at its insertion end. This layer is quite derived from MgO, however it can also come from Ba203 or another insulating material. This layer is 50 mm thick; it can also be slightly thicker. The coating is 2.5 mm long towards the refractory body. Between this area, the electrically insulating material 8 is arranged on the small electrolyte tube and the refractory material embedded in the small solid male electrolyte tube 7 'There is an uncoated area of about 11 mm long, the so-called active part of the electrochemical element 1 Copies. Regarding the measurement, the measurement cell is inserted into the slag layer on the molten steel. Here, the electrochemical element 1 is surrounded by slag, so the slag is also inserted into the molten steel. The temperature balance of the molten steel in the area of the electrochemical element 1 is quickly reached, and the oxygen activity of the liquid slag layer is measured. The cardboard 10 arranged on the opposite electrode 6 avoids ore through the slag layer; it is adhered to the opposite electrode 6. Starting at this time, the counter electrode 6 is directly in molten contact with steel during measurement. No electrical insulating material 8 is used on the electrochemical element 1, but other materials can also be used, which causes slag to adhere to the electrochemical element 1. The electrochemical element j, which protrudes from the adhesive 2 by about 9 to 13 mm, especially 11 mm, can be more rounded by a small tube, such as an electrode 6 protected by a cardboard 10 on the outside, creating a ring Ring area shown in 2 and 3. Here, the cardboard 10 does not need to form a kind of cover which covers the entire surface of the opposing electrode 6, but it can also be arranged on the outer surface of the opening of the opposing electrode 6, for example, using an adhesive tape. Circle 4 represents a measuring cell in which the active part is the annular surface 9 of the electrochemical element. In Figure 5, the arrangement of the electrochemical elements is shown in the molten bath, the slag adheres to the active part, and the counter electrode has been partially dissolved and coated by the ore part. --------- ^ · Installation ------ order ----- Λ bowl (Please 4?
