Many properties can be identified through coloring, contrasting, and closing values. In particular, it is easy to determine the degree of wear, glass-refractory interfacial displacement, or the position of the see-through boundary. Verification is used to verify the visual inspection. The scanning method was designed to improve the accuracy of the evaluation of the corroded specimens, not the microstructure study. In fact, the magnification obtained with the flatbed A4 scanner is limited, which is related to the optical resolution of the device (usually 600 dpi to 120odpi). According to the traditional cinder test method, the finely-ground abrasive substances are applied to the refractory mass increase sample block at the furnace test temperature. A hollow cylinder is cemented to a square bottom parallelepiped plate. 15 grams of container glass was placed on each mandarin. The less material is expected. In order to obtain accurate results, the remaining glass surfaces were scanned using the novel scanning technique described above without the use of old time-consuming planar measurement techniques. In addition, surface penetration was also measured.
The operation steps are as follows: l) sample scanning; 2) image processing; 3) stereo calibration and conversion of pixels into dedicated length units; 4) surface measurement of the selected area by image processing such as contrast and threshold determination, and then The depth of penetration was statistically characterized. This can be done by making a series of measurements along the impregnation zone. Using the standard deviation, a reliable assessment of the seepage uniformity can be made, and the average degree of impregnation data can be determined.
The PRI product has a large surface area of ​​the remaining glass sprayer in all samples. In addition, the degree of seepage is only limited to a small part of the dried fruit. The non-corrosive phenomenon of the refractory material in the interface region with the glass, even at the glass surface line, may be a result of the low degree of impregnation. The sample was placed in an electric oven, heated to 1400°C in 14 hours, then soaked at 1400°C for 24 hours, and then cooled to room temperature in an electric furnace. Select the soaking temperature that simulates the actual operation. During the measurement, the sample is cut in half to allow cross-section inspection of the glass-refractory interface. In order to reliably quantify the glass erosion resistance of refractory materials, the cross-sectional area of ​​the remaining glass was measured.
The ladle verified the technical feasibility of the new alkali spray material (NB-GM) for slag line repair, especially the product. The further study was conducted to find the most suitable product/equipment. The first industrial test was carried out in the laboratory and sprayed on the MgO-C slag line. The properties were as follows: Weight loss after 110°C. B, Product 5.5% Bulk density Porosity at room temperature Compressive strength 2.69/m3,319% 3lMPa It was confirmed This material has excellent performance compared to ordinary alkaline spray products. RH-OB Vents New materials reduce the total consumption of aluminum (external) and alkaline (internal) materials used for repairs compared to ordinary spray-off products. Ongoing tests are mainly focused on automatic spraying equipment, especially suitable for practical applications. This has the same effect as the common material used previously. The first comprehensive tests of these first tests were very useful, and they clearly demonstrated improved performance compared to ordinary spray materials. Two similar studies have indeed confirmed the future trends of LC-GM (aluminum) and NB-GM (magnesium) materials. The new optimization equipment has the best masonry operation, ie no dust and rebound, and the masonry rate is 5 to 6 t/h. The new product, especially the aluminum spinel monolith, is more suitable for the overall masonry of the ladle.
