Many characteristics can be identified through color differentiation, contrast adjustment, and value closure. Specifically, it is straightforward to assess the degree of wear, glass-refractory interfacial displacement, or the location of the see-through boundary. Verification is conducted to support visual inspection. The scanning method was developed to enhance the accuracy of evaluating corroded specimens, rather than for microstructural analysis. In fact, the magnification achievable with a standard A4 flatbed scanner is limited, typically ranging from 600 to 1200 dpi, which depends on the device's optical resolution. According to the traditional cinder test procedure, finely ground abrasive materials are applied to refractory mass increase samples at furnace test temperatures. A hollow cylinder is cemented onto a square-bottomed parallelepiped plate. Each mandarin is loaded with 15 grams of container glass, with the aim of minimizing material usage. To achieve precise results, the remaining glass surfaces were scanned using the newly developed scanning technique, avoiding the outdated and time-consuming planar measurement methods. Additionally, surface penetration was also evaluated.
The process involves several steps: 1) sample scanning; 2) image processing; 3) stereo calibration and conversion of pixel measurements into standardized length units; 4) surface measurement of selected areas using image processing techniques such as contrast and threshold setting. The depth of penetration is then statistically analyzed by taking multiple measurements across the impregnation zone. Using standard deviation, an accurate assessment of seepage uniformity can be made, and the average level of impregnation can be determined.
The PRI product demonstrates a significant surface area of remaining glass sprayer in all samples. Moreover, the degree of seepage is restricted to only a small portion of the dried fruit. The lack of corrosion in the refractory material at the glass interface, even at the glass surface line, may result from the low level of impregnation. The sample was placed in an electric oven, heated to 1400°C over 14 hours, held at that temperature for 24 hours, and then cooled to room temperature in the same furnace. The soaking temperature was chosen to simulate real operating conditions. During the measurement, the sample was cut in half to enable cross-sectional inspection of the glass-refractory interface. To reliably quantify the glass erosion resistance of refractory materials, the cross-sectional area of the remaining glass was measured.
The ladle confirmed the technical feasibility of the new alkali spray material (NB-GM) for slag line repair, especially for this specific application. Further studies were carried out to identify the most suitable product and equipment. The first industrial test was conducted in the lab, where the material was sprayed onto MgO-C slag lines. The properties included weight loss after drying at 110°C, with Product B showing 5.5% weight loss, a bulk density of 2.69 g/cm³, porosity of 31.9%, and compressive strength of 31 MPa. This material was confirmed to perform exceptionally well compared to conventional alkaline spray products. The RH-OB Vents new materials reduce the total consumption of aluminum (external) and alkaline (internal) materials used for repairs when compared to regular spray-off products. Ongoing tests focus primarily on automatic spraying equipment, particularly those suitable for practical applications. These systems produce the same effect as previously used common materials. The initial comprehensive tests proved very useful, clearly demonstrating improved performance over traditional spray materials. Two similar studies have indeed validated the future trends of LC-GM (aluminum) and NB-GM (magnesium) materials. The new optimized equipment offers superior masonry operations, characterized by no dust or rebound, with a masonry rate of 5 to 6 tons per hour. The new product, especially the aluminum spinel monolith, is more appropriate for full-scale masonry of the ladle.
