    111 The invention relates to the production of sheet glass. A known method for the continuous production of surface-modified glass by moving a glass ribbon on the surface of the molten metal, which contacts the upper surface with a fixed mass of the melt of two metals and a solvent under the conductive plate at a temperature of 600-900 ° C, which is supplied with an electric current l. However, during the migration of metal stems from the fixed mass of the melt to the glass surface, a change in the composition of this melt occurs, which negatively affects the proportions of migration. The purpose of the invention is to provide the migration of molten metals to the surface of the glass in predetermined proportions. The goal is achieved by the method of continuous production of surface-modified glass by moving a glass ribbon across the surface of the molten metal, contacting the upper surface with a fixed mass of the melt of two metals and a solvent at a temperature of 600,900, under which a current is applied, a conductive plate made of an alloy of metals of the same name as the metals of the melt, in the same proportions. The drawing shows the implementation of the proposed method. The method of continuous production of surface-modified glass is carried out as follows. Molten metal 1, for example tin or tin-based alloy, is contained in a bath having a base 2, side walls 3 and end walls 4 and 5. Above the inlet end wall 4 passes a chute 6 through which liquid glass 7 is supplied to the surface 8 molten metal 1 under the control of the regulating valve 9. The bath has a crushing 10, forming a cavity 11, into which a protective medium is supplied through pipelines 12, for example, consisting of 95% by volume of nitrogen and 5Z by volume of hydrogen. A glass ribbon 13 is formed by supplying liquid glass 7 to the surface of a bath of molten metal 1 and subsequent spreading along it to form a layer of liquid glass, which then moves in the water of the ribbon along the surface 8 of the molten metal 1 under the action of traction force applied to the ribbon at the output end baths with traction rollers 14 feeding the ribbon into a glass annealing furnace. When moving along the surface of the molten metal, the glass ribbon is cooled until it is strong enough so that it can be removed from the bath. A conductor plate 15 is mounted across and above the top surface 16 of the glass ribbon. A fixed mass of the melt 17, consisting of a solvent and two metals, the ions of which must migrate from the surface 16 of the glass ribbon, is attached to the bottom surface 18 of the conductive plate 15 with a key 19, which is set with the possibility of free re-centration in the holder 20 fixed on electrically isolated pillars 21 going from water-cooled beam 22. The conductor plate holder 20 is connected by a wire 23 to a terminal of a power source 24. Another source terminal is connected via wire 25 to electrode 26, which is immersed in a molten metal bath adjacent to a conductive plate 15. When power supply 24 provides a steady DC current, conductive plate 15 is an anode with respect to the bath. When the source of the pitaya switches to the manufacture of glass with a vacuum, a switched anode wave arrives at the conductive plate 15 through the wire 23. The fixed mass of the melt 17 consists of two metals (for example, copper and tin, or silver and tin), the ions of which electrolytically migrate into the glass ribbon under the action of applied voltage. The current plate 15 with the bottom surface 18 is made of an alloy of metals of the same type as metals of a fixed mass of the melt 17 in the same proportions. The bottom surface 18 of the conductive plate 15 dissolves in the fixed mass of the melt 17 as the migration of metal ions from the fixed mass of the melt into the glass ribbon occurs. Thus, the fixed mass of the melt is replenished by dissolving the bottom surface 18 of the conductive plate 15. The specific combination of metals and the relative content of each of the metals depends on the desired effect, for example, on the color or other properties that must be communicated to the glass. The conductor plate 15 is located in a bath with molten metal 1 in a position where the temperature of the fixed mass of the melt 17 varies between 600 and 900 s. The solvent metal is a metal that, at operating temperature

    f 2854 round forms an alloy with metals that must be introduced into glass. The solvent should have a slight tendency to migrate into the glass ribbon, as a result of which the alloy metals migrate preferentially. However, this provision is not necessary and in some cases it is preferable to migrate the metal of the solvent into the glass. The migration of ions from the stationary mass of the melt to the surface of the Tape of glass can be enhanced by regulating the oxygen concentration in the mass of the melt. The invention allows the continuous production of surface-modified glass while maintaining a constant degree of modification by maintaining the constancy of the composition of the fixed melt mass.
