And is affected by the tin bath atmosphere, resulting in uncontrolled pressure and temperature of the slag box. Because the uncontrollable of traditional slag box technology leads to the drawback of traditional molten tin bath slag box more:

1) oxide is easy to gather by electrical heating in the upper cover body of the slag box, and the gathered oxide contacts the glass plate to cause the upper surface of the glass plate to be scratched;

2) the lower cover body of the slag box is easily covered by oxides, sulfides and cullet when being electrically heated, and the transition roller can be scratched when the accumulation is higher, so that the production accident of plate breakage can be caused seriously;

3) the electric heating of the blowing slag box can influence the process of the slag box, and the transition roller is easy to be polluted;

4) the pressure fluctuation of the slag box can cause the falling of oxides condensed in the upper cover body of the slag box, one part of the falling oxides falls on the glass plate to form defects on the upper surface of the glass plate, the other part falls on the transition roller to pollute the transition roller, and after the transition roller is polluted, the falling oxides contact the glass plate to cause regular dense fine scratches on the lower surface of the glass plate;

5) the source of molten tin bath slag box temperature is the temperature of molten tin bath waste gas temperature and glass board, and under the certain condition of glass board temperature, molten tin bath waste gas gets into the slag box upper cover body preferentially, leads to the interior glass board of slag box about the surface difference in temperature great, and the glass board forms great permanent stress, and permanent stress can cause the glass board to break to a certain extent, also can cause the glass board cutting difficulty.
