The invention belongs to the technical field of glass production, and in particular relates to a liquid flow control device for float glass and an installation method thereof. The installation of lip bricks is carried out after the baking temperature of the cooling part of the furnace, the runner bricks and the tin bath reaches the target, and the expansion of the cooling part of the furnace, the runner bricks and the tin bath has also been completed. The position of the brick has been fixed. At this time, the calculation makes the installation of the lip brick in the most ideal position in the design. Considering the expansion of the lip brick, the actual calculation and measurement of the size of the installation position of the lip brick, the length of the pre-installed lip brick is cut And grinding, in order to meet the calculated standard reflow length L1, adjust the horizontal height during the installation of the lip brick, so that the lip brick is installed in the most ideal position during design, so that the lip brick bakes and heats up, and the expansion length of the lip brick It has been calculated in advance that after the lip tiles are baked, the liquid flow backflow length L between the lip tiles and the wet back tiles is equal to or basically close to the standard backflow length L1, so as to achieve precise control of the glass liquid flow.
Description
technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a liquid flow control device for float glass and an installation method thereof. Background technique [0002] Although we have accurately calculated the change of float glass liquid flow in the runner area, in the cold state, after the installation of each part according to the design requirements, it will be baked along with the cooling part of the furnace, runner bricks, lip bricks and tin bath The amount of expansion is different. Due to the inaccurate control of the construction and the thermal expansion direction of each part, at the end of the baking, the expansion of each part is superimposed on each other, which makes the reflow length L that we need to accurately control change greatly. Once the reflow length L is formed It is difficult to correct. In the later production process, due to the change of the reflow length L, the reflow part of the glas...
