Description

Determination of the interelectrode distance is of great importance for the establishment of the normal operation mode of magnesium baths, i.e. L1a; their maximum performance with minimum electric power consumption.

Pro: leading research work has shown that with a decrease in the interelectrode distance below the known limit, the current output in the bath begins to fall rapidly. On the other hand, a large interelectrode distance leads to an unnecessarily high voltage on the bath, i.e., to over-electrical energy consumption, to the inclusion of baths with a large interelectrode distance and to a decrease in the efficiency of the series.

One of the BASIC X. PICTURES OF HIGH VOLTAGE on the baths is the high interelectrode distance of them. The absence of an instrument for measuring the interelectrode distance leads to the fact that the quantitative 1–1 = 1 cost between the current output and the interelectrode distance of the IB baths has not been studied, and the possibility of decreasing (existing, their current time between the electrodes) the current is not completely understood and, consequently, is not used.

The interelectrode state in magnesium baths is not measured due to a number of difficulties associated with this operation.

In modern high-power magnesium baths, the distance from the bath surface to the upper edge of the cathode sheet is about 1 meter, to its lower edge - about 1.7 meters.

In Ov zi With large cathode I1 sheet sizes, observed in Hai practice cases, firstly, deviations of the cathodeal sheet from the vertical position, and, secondly, non-parallelism (in plan) of the cathodeal sheet in relation to the working surface of the anode, the measurement of the interelectrode distance at each cathode it is necessary to produce no less. Than in the four most distant friends; from each other on the top and bottom edge of the bale: the cathode sheet.

In the proposed device, these difficulties are eliminated by the fact that / instead of a rod, a pipe is applied, one end is used to fasten the fixed jaw. The second end of the pipe carries a cover for the base of the measuring rod passing through the cavity of the pipe. The latter is connected by a flexible bond with a movable sponge.

In FIG. 1, depicts

proposed device, FIG. 2 -

installation of the device at the time of use. them.

The proposed device is designed according to the principle of the Shangen-tsvrkul. Instead of the rod, T1rub / was used, carrying at one end a fixed sponge U-, and at the other end-Krshka 9, serving as a rim / acting for the measuring rod 2. Meter fBra yut rod 2 has a split-I and is connected by a flexible link 1C, a moving sponge 5. Hybrid communication can be performed by IB in the form of an irregular type. -; .

The device through the gap between the diaphragm 6 and the cathode 7 is introduced into the space between the electrode 1 MI, "is launched onto the upper edge of the cavity; 7 And (advances along it to the sonny of the fixed jaw 4 with the anode S.

After (THIS measuring rod 2 raises up to the handle of the failure, upwards, i.e., until the moving jaw 5 contacts the cathode 7, I1, the distance between the legs is measured on the rod. When the mobile ynoip is lowered, the ynoip returns to its initial position and measures .but be produced (re.

In order to accommodate readings, the rod 2 with divisions applied on its own can be rotated around its axis.

For the manufacture of the lower chamber, the cathode device; slightly modified - it is made longer, the sponges are not upwards, but upwards; the measurement method remains the same.

During the first measurement, the pipe / cathode and anode are measured, i.e., it produces a short circuit between the electrodes. It is therefore necessary; to isolate the end part of the fixed sponge with the help of a refractory plate.

The adjustable device provides for the possibility of its adjustment. Upper yryshka 9 is cut throughout the height. By screwing or screwing on the lid I, it is established when checking the device that the lid surface coincides with the corresponding division on the pin.

Flexible hinge section of the movable part (the tool is designed, based on the need to | move | the movable sponge 5 to the initial position by lowering 2.

(Another method of returning the movable sponge IB is possible is the initial position — by moving the device from the anode; to the cathode, without detaching it from the upper edge of the cathode. In this case (the flexible-mobile section could be made from an ordinary chain.

When: for the manufacture of heat-resistant steel for the manufacture of flexible steel, the flexible hinge section is replaced with a thin PROTECTION of heat-resistant steel placed in an iron tube of somewhat larger diameter. The heat resistance of the wire prevents it from oxidizing at | The electrolyte temperature is about 700 ° C, and its small diameter is due to its flexibility. This way, not only the technology will be provided, but also the low weight of the device.
