Through the coloring, contrast and set the value, can find out a lot of performance, in particular, can easily determine the degree of wear, glass-refractory interface displacement or infiltration boundary position; with a quantitative value of visual inspection. The scanning method is intended to improve the accuracy of the evaluation of corroded specimens, rather than for microstructure studies. In fact, the magnification obtained with a flatbed A4 scanner is limited, which is related to the optical resolution of the device (typically 600 dpi to 120odpi). In accordance with the traditional test method, at the test temperature of the kiln, the finely ground aggressive material acts on the refractory materials for furnace. Use a cement to bond the hollow cylinder to a square bottom parallelepiped. Each of the citrus fills 15 grams of container glass. The less the material. In order to obtain accurate results, the residual glass surface was scanned with the new scanning technique described above without using the old time-consuming planar measurement technique. In addition, surface osmosis was measured.
2) image processing; 3) three-dimensional calibration, the pixel conversion into a dedicated length unit; 4) by contrast and threshold determination and other image processing on the selected area for surface measurement, and then on the Infiltration depth for statistical description. This can be done by making a series of measurements along the impregnation area. Using the standard deviation, the infiltration uniformity can be reliably evaluated, and the average value of the impregnation can be determined.
PRI products in all samples, the remaining glass spray paint surface area. In addition, the infiltration degree is limited to a small part of the wall thickness of citrus. The refractory material in the interface area in contact with the glass is free of erosion, even at the glass level, and the result may be low against the degree of impregnation. The sample was placed in an electric furnace, heated to 1400 ° C in 14 hours, then warmed at 1400 ° C for 24 hours, and then cooled to room temperature in an electric furnace. Choose to simulate the actual operation of the soaking temperature. When measuring, cut the sample in half so that the glass-Refractory company interface is cross-section tested. The cross-sectional area of ??the remaining glass was measured by a reliable quantification of the glass-resistant erosion resistance of the firebrick refractory sale.
The ladle package verifies the technical feasibility of the new alkaline spray filler (NB-GM) for slag line repair, especially the product. Further research is done to find the most suitable product / equipment. The first industrial test is carried out in the laboratory, the spray of MgO-C slag line, the performance is as follows: 110 ℃ after the weight loss B, product 5.5% bulk density porosity at room temperature compressive strength 2.69 / m319% 3lMPa it confirmed This material with ordinary alkaline spray products compared to excellent performance. RH-OB Ventilators Compared to conventional spray products, new materials can reduce the total amount of aluminum (external) and alkaline (internal) materials used for repair. The ongoing tests are mainly focused on the automatic installation of the spray, especially for practical applications. This has the same effect as the conventional material used previously. The first comprehensive test of these first tests was very useful, and they clearly confirmed the improved performance compared to conventional jetting. Two similar studies confirm the future trends of LC-GM (aluminum) and NB-GM (magnesia) materials. The new optimization equipment has the best masonry operation, that is, no dust and rebound, masonry rate of 5 a 6t / h. New products, especially aluminum spinel amorphous material is more suitable for ladle overall masonry.
