[China Glass Net] First of all, we must consider whether the power value of the heating wire is uniform. The inspection method can be judged by measuring the current intensity of the wire. The aging of the furnace wire during use will affect its power, or the use of different manufacturers' furnace wire will also result in a large power deviation. As shown in Table 1, the TAMGALSS convection oven is taken as an example, and the current value passed there is deviation: from the above table, the average upper wire is 54.6A, the upper corner is 21.5A, the lower part is 55.4A, the lower corner is 21A, and the large value is Small values ​​differ by 8A or 15% deviation. Such deviation directly reflects the deviation of the heating power by 15% without considering other factors, which greatly affects the uniformity of the tempering temperature field. By default, the deviation is controlled within 10%, that is, the current of the furnace wire is within 5A. If the current is lower than the range, the length of the furnace wire can be properly cut and continued to balance. Most of the currents above the range are recommended for direct replacement. After the problem of furnace wire is solved, it is necessary to check the state of the radiant panel, and the radiant panel is required to be on the same level. This horizontal plane should be measured according to the level of the roller table. Make sure that the distance from the glass to the radiant panel does not exceed 3 mm (experience value). At the same time, we must consider the influence factor of convection, which is very large for convection heating glass. There are three points in this control. One is that the blowing intensity is the same, the second is that the blowing direction is the same, and the third is that the sealing height is consistent. In order to better ensure the long-term stability of the temperature field, it is necessary to measure the temperature of the outer wall of the furnace. It is recommended to carry out external insulation after exceeding 50 °C. Otherwise, the heat loss will be too large and the temperature fluctuation of each furnace will be too large. If the convection can be turned off without considering the cost, direct heating with radiation, so that the stress spot effect is better, or the effect of the glass stress spot produced by the continuous furnace is better than that of the double chamber furnace.
Velvet Fabric is a type of soft fabric that has a dense pile. It is made from a variety of fibers. Velvet Fabric has a distinctive texture that is created by weaving two layers of fabric together, then cutting the threads on the top layer to create a short, dense pile. This pile gives velvet its soft and plush feel, as well as its rich and lustrous appearance. It is commonly used in home decor for items such as upholstery, curtains, and pillows. Velvet can come in a variety of colors and patterns, and is often associated with elegance and sophistication.
