    1 The invention relates to the building materials industry, in particular, to the production of hardened glass products. There is a known method of creating a pseudo-fluidized layer by mixing a catalyst from aluminum silicate of a silica binder with particles with residual magnetization of powdered ferrite in the form, where X is metal or mixed metals such as manganese, barium copper and strontium. The mixture is subjected to a magnetic field that stabilizes the fluidized bed, clly Cl. There is a known method for processing dispersed material when sand is mixed with barium ferrite particles by passing up gas through this mass and by applying a magnetic field, the intensity and direction of which change 2j. The closest in technical essence and the achieved result to the proposed method is the processing of dispersed material to create a fluidized bed, including the preparation of a dispersed mixture of non-magnetic particles, such as alumina, and particles with a residual magnetization and an electromagnetic field controlled by its magnitude and direction. SPZ. However, the known methods do not both bake high quality tempered glass, because they do not create a uniformly fluidized bed. The purpose of the invention is to increase the quality of glass. This aim is achieved in that according to a method of treating particulate material to provide a fluidized bed, preferably for tempering glass izdedy comprising the preparation of the dispersion of nonmagnetic particles of the group of alumina, silica-alumina, alumina monohydrate, trigydrat al1shini or sodium bicarbonate and the particles having a residual magnetization, and the impact on it of an electromagnetic field that is adjustable in magnitude and direction, a dusty magnetic field is introduced as particles with residual magnetization Mbps general formula AB, where A - barium, strontium, or lead; O - oxygen, B - aluminum, gadolinium, chromium or iron, or an alloy of at least two metals; groups of iron, cobalt, nickel, aluminum, and the treatment is carried out in a wandering electromagnetic field, which is moved linearly through the mixture. Moreover, the electromagnetic field is stirred up. As a dispersed material, barium hexaferrite is used with an average size with a particle size range of 20-300y t and, moreover, 76% of the parts have a size. The dispersed aluminum triglydrate is characterized by an average particle size of 66 (UM and a particle size range of 20–120 m.) Before mixing with aluminum trihydrate, dispersed hexaferrite barium is permanently magnetized by pouring powder into a pipe and moving this pipe between the poles of a permanent magnet with field strength A / m. Sheets of glass with a size of 250 x 250 mm and a thickness of 2.3 NM are suspended on the grips and heated in an oven to an average temperature of 650-680 C, after which they are cooled in a dispersion of a mixture of hexaferrite barium and aluminum trihydrate containing 100% by weight of aluminum trigdrate to 100% by weight of barium hexaferrite. The temperature of the mixture is maintained at the level of OO-S. The average central tensile stress caused in each cooled sheet is measured by averaging the values measured at the top, middle and the lower parts of each sheet of glass. The results are presented in Table 1.
    Table 1
    These results show that the magnitude of the average central tensile stress induced in glass increases as the proportion of powdered ferrite in the mixture increases to 32.5 wt.%. When using one ferrite, less stress arises and a large amount of air is required to avoid agglomeration.
    Quenching voltages occurring in glass can be regulated by varying the current supplied to the motor windings, as well as by adjusting the frequency of the power supply.
    Examples 13 and 17 show how the central tensile stress caused in glass with a thickness of 2.3 mm affects the variation of the current supplied to linear motors in the range of 40-80 A. The same mixture of hexaferrite serves as a dispersed material. barium and aluminum trihydrate, as in examples 1-12. The mixture consists of 25 wt.% Barium hexaferrite and 75 wt.% Aluminum trihydrate. Air flow rate 25 l / min.
    The results are given in table. 2. Table2 S As can be seen from table. 2, the central tensile voltage increases by increasing the current or power supplied to the motor windings. Examples 18–21 show how the change in the frequency of the electric current in the range of 50–87 Hz at a constant current strength of 30 A affects the magnitude of the average central tensile stress induced in glass 2.3 mm thick. the same as in Examples 13-17, a mixture consisting of 25% by weight barium hexaferrite and 75% by weight aluminum trihydrate. The motor used and the air flow rate are the same as in the previous examples. The results obtained in examples 18-21 are given in table. 3. TABLE 3 Examples 18–21 show that the strut central tensile voltage increases with increasing frequency of the power supply. Vary glass thickness, for example in the range of 1-25 mm. Examples 22 and 2 illustrate the thermal hardening of sheet glass size. 300 X 300 mm, which is cooled in a dispersion of a powder containing 25 wt.% Barium hexaferrite with a mean particle size and a particle size range of 20-125 jLtM, mixed with 45 wt.% Aluminum trihydrate with an average particle size of particles 20-120 (UM. The results are shown in Table 4. 28 The fluid-generating gas is supplied to the bottom of the container. Glass sheets measuring 300 x 300 mm and 3 mm thick are heated to 650-680 ° C and then subjected to quenching in the dispersion of material particles , whose temperature is 25-40 C. O r and m 24.
