The invention relates to the field of metallurgy of non-ferrous metals, specifically to a device for refining magnesium. Known furnace for refining magnesium, comprising a casing, lined mine with the electrodes, the arch with a Central shaft and pipes for loading and unloading of molten materials (U.S. Pat. RF 2283886, SW 26/22, F27B 17/00). One of the drawbacks of such a furnace is a large open surface of liquid magnesium, require protection from oxidation. Known furnaces for refining magnesium bell [Lebedev, O.A., magnesium Production by electrolysis. M, metallurgy, 1988; U.S. Pat. RF 2222623 SW 26/22, F27B 17/00; Pat RF 2228964 SW 26/22, F27B 17/00], in which the bell for magnesium immersed in a heating his salt medium containing the chlorides of potassium, magnesium, sodium and barium. Bell has the pipes for loading and unloading of magnesium, cross-section, which is significantly less than the open surface of the magnesium in the furnace, not containing bells. Furnace, bell type can significantly reduce the loss of magnesium oxidation on the surface of the proportionately lower open surface of the magnesium. Currently operated furnaces for refining magnesium both of these types. The present invention aims to improve the design of the furnace "bell" type, with the aim of improving its performance characteristics of the AK technology, and economic. The closest analogue, selected as a prototype, is a continuous furnace for the refining of magnesium on the patent of the Russian Federation 2228964, SW 26/22; F27B 17/00, containing the code, the casing is lined with a bathtub with electrodes installed inside the bell with two pipes with removable craters and refining chamber; the bell has a Central vertical channel with vertical radial ribs, between the two of them made the bottom, and the other fins are with the formation of the labyrinth for refining magnesium. From the description of the patent it is known that around the bell is heating the electrolyte composition: 10-18% MgCl2, 10-20% NaBr or 5-7 BaCl2, 18-20% of NaCl, KCl - rest, and at the bottom refining (casting) of the cell is the electrolyte of the electrolysis bath composition: 5-10% MgCl2, 20-30% of NaCl, KCl - rest. Periodically 1 time per shift from the priming chamber choosing vacuum ladle accumulated electrolyte electrolysis baths come with magnesium-raw. The disadvantages of the furnace of the prototype include: - Using BaCl2, which is a potent poison and a possible source of poisoning of staff. NaBr is quite "exotic" salt is not used in magnesium production. In addition, the loading of salts, their preparation requires updat the additional time and effort, reduce labor productivity. The use of barium chloride in a known flux mixtures due to the need of weighting them in the refining of magnesium or alloys input flux from the top. In large refining furnaces flux for refining the top is not introduced and therefore the use of weights (BaCl2, NaBr) is not required. Bottom loading chamber substantially complicates the technology of processing of magnesium in the furnace. Firstly, there needs surgery removal of salt from the loading chamber, otherwise magnesium in it to accumulate and the total capacity of the bells on magnesium decreases. It is impossible to remove the known devices the sludge from the loading chamber. Secondly, when pumping magnesium from the discharge pipe of the magnesium from the loading chamber (if it still exists) is pumped under hydrostatic conditions, i.e. reduced working capacity bells on magnesium on the volume of loading chamber. Thirdly, when removing accumulated in the loading chamber inevitably salt along with the salt will fall and magnesium, i.e. will increase the loss of magnesium. These negative aspects of the device of the bottom of the loading chamber were examined in the testing of hydraulic model of the furnace. The objectives of the proposed technical solutions are: simplification and stabilization service technology RAF is planning furnace, the reduction of losses of magnesium, excluding hazardous components of the composition of the tea salt. Technical results achieved by the fact that in the bottom between the ribs made the hole opposite boot outlet, boot removable funnel immersed in the bell and Cup-shaped ends of the guide thread, and as the tea salt is used the working electrolyte in magnesium electrolytic cells. In addition, the hole diameter is not less than the diameter of the loading branch pipe, and the area of the holes is 0.1 to 0.8 of the total flow area perechodnik channels ribs. In addition, the end of a feed hopper buried in a Cup-shaped guide thread, and the distance from the funnel to the bottom of the guide is 30-80 mm In addition, the diameter of the guide at 30-80 mm greater than the diameter of the end of the loading hopper. In addition, the hopper immersed in the bell by 0.1-0.5 height. The implementation of the holes in the bottom of the unites salt environment of the furnace, eliminates hydraulic "bags", allows you to fully utilize the volume of the bells for magnesium. The location of the holes in the bottom front of the loading branch pipe allows burned in the pipe magnesium freely fall down to the furnace hearth furnace, where the solid particles can be removed by the grapple through the Central vertical channel. Cup-shaped direction of the Commissioner at the end of the charging funnel directs a stream of magnesium when pouring from the ladle up to peritonism channels and further transportation to the discharge nozzle, not letting down the flow of magnesium in the lower layers of the furnace. The working electrolyte as the tea salt allows you to: eliminate dangerous and rare salt additives (BaCl2, NaBr); apply used in the production of magnesium salt mixture, in which the magnesium satisfactorily refineries and POPs up (separated), which has been proved by years of practice electrolytic production of magnesium in the electrolyzer cells and production lines. All parameters are set and reviewed on a water model and confirmed by the practice of trial operation of the furnace. Conducted by the applicant's analysis of the prior art, similar to the proposed technical solution, showed that it has the characteristics of "novelty" and meets the condition of "inventive step". Figure 1 shows a cross-section of the furnace, figure 2 - site installation guide thread on the feed chute. In the drawings, the numerals marked: 1 - furnace lining, 2 - electrode, 3 - bell, 4 - vertical channel bell, 5, 6 - ribs bells, 7, 8 - peritonei channels in the ribs 9 of the bottom between the ribs 6, 10 - pipes of bell 11 - detachable funnel for loading and unloading of magnesium, 12 - Cup-shaped guide thread on the feed chute, 13 - boot Luggage, 14 - hole in the bottom 9. The drawings are marked by letters: D - diameter of the loading p is the pipe bell 10, d is the diameter of the holes 14 in the bottom 9, b - depth of the funnel into the bell 3, h - height of the bell 3, and the diameter of the loading hopper at the bell, with the diameter of the Cup-shaped guide, the distance from the end of the loading hopper to the bottom of the Cup-shaped guide. The arrows show the direction of flow of the melt. The oven works as follows. In the oven pour the working electrolyte of the cell composition: 10% MgCl2, 20% NaCl, 70% KCl to full closing bell melt. Through electrodes 2 AC heat the Sol to 710°C. Further from the vacuum ladle through the funnel boot 11 download the magnesium raw (capacity vacuum ladle ~2 t). The flow of molten magnesium, penetrating through the feed chute to guide a flow of 12 receives the upward direction, because the way down is blocked. Climbing up the flow of the magnesium gets in peritonei channels 8 and moves in the direction of the discharge pipe. After filling bell magnesium defend 20-30 minutes and discharged (pumped by the pump) on the casting conveyor. Magnesium raw refinished by settling and by "refinement" of contact of magnesium and molten salt. The hopper periodically removed from the furnace for washing in the washing salt furnace, thus clear from growths boot outlet. Detached pieces harder melt, so they open the e 14 in the bottom of the loading chamber 13 will be taken to the furnace hearth furnace, which periodically retrieves the grapple through the vertical channel of the bells 4. Clean the funnel and the pipe is necessary technological operation. Because the diameter d larger than the diameter D, the pieces may large magnitude penetrate through the opening on the furnace hearth furnace. The depth infeed in bell b ensures optimal flow management in the upper zone of the bells and configuration guide (cacheobject) flow allows you to generate the correct direction and speed of flow. The relative sizes of the elements bells investigated water models and their optimality is confirmed working prototypes of the oven. The table shows the justification specified in the technical solution of the parameters. The hydraulic resistance of the holes in the bottom stream of magnesium should be greater than the hydraulic resistance perechodnik channels, make sure to direct the flow in peritonei channels, and not in the bottom hole. This condition is ensured by the reduction of the area of the hole relative to the total area of perechodnik channels. Thus, the proposed technical solutions that simplify the technology of servicing the furnace device holes in the bottom of the bell, reduce loss of magnesium due to the exclusion of the operation of cleaning the loading chamber of the bell from the elect who Olite in the presence of openings in the bottom eliminate the use of hazardous to human health components of salt. Test furnace showed the validity of the proposed solutions. Recycled more than 500 tons of magnesium raw, all the resulting magnesium-compliant. Loss of magnesium was less than 5 kt per 1 ton of magnesium.
