The invention provides a method for reducing zinc ash and zinc residues in a zinc pot. Alumina ceramic beads with the diameters phi of 7-15mm are added to the surface of zinc in the zinc pot, and are densely and uniformly tiled on the zinc surface in a three-layer or four-layer manner, and the thickness is about 20-45mm. The method has the following advantages: the heat loss can be reduced and the oxidation can be prevented because the alumina contained ceramic beads have the characteristics of anti-oxidation function, small heat conductivity, high melting point, small specific gravity, and no reaction with molten zinc. Alumina has an iron removal function, so the formation of iron impurities of the zinc pot is reduced. The beads which are balls can be pushed away by workpieces, and do not adhere to the workpieces. The method well controls the generation of the zinc ash and the zinc residues in the zinc pot.

The invention relates to a zero-clearance bracket used for the orthodontics. The zero-clearance bracket used for the orthodontics comprises a bracket body, wherein the bracket body comprises a bottomplate and a foundation support; one side, which is far away from the bottom plate, of the foundation support is provided with an upper spacing wing and a lower spacing wing; on one side, which is faraway from the bottom plate, of the foundation support, an arch wire groove used for placing a correction arch wire is arranged between the upper spacing wing and the lower spacing wing; the foundationsupport is provided with a movable groove of which the length direction is vertical to the length direction of the arch wire groove; the movable groove communicates with the arch wire groove; in themovable groove, a pressing block abutted against the correction arch wire is arranged; and a ligation wire used for tightly pressing the pressing block is jointly sheathed to the upper spacing wing and the lower spacing wing. Through the above arrangement, the pressure of the ligation wire tightly presses the pressing block to the direction of the correction arch wire, and the pressing block reduces a gap between the correction arch wire and the arch wire groove so as to improve a torque and correction force expression effect of the correction arch wire in a correction process. In addition, utilization of fixing parts is reduced, so that the zero-clearance bracket can be more easily operated in the narrow space in the oral cavity, the foreign matter feeling of a user is not obvious, and the comfort level of the user is improved.
