Sažetak
Refrigerating plates for external thermal insulation of the blast furnace furnaces are made in the sizes (140...180) x (1 000...2 500) x (500... 1 500) mm by filling with cast iron a coil of steel pipes. This can cause shrinkage shells and indigestion, which worsen or even damage the entire product. In practice, quality control of refrigeration plates was carried out, mostly by tapping (to detect internal voids), visually (to assess the appearance) and so on. In this regard, the analysis of the manufacturing technology with the definition of the process critical control points and the available means of the product quality identifying at these points and their effectivity was realized. As a result, it is proposed to use certain objective means of control at critical control points, based, in particular, on penetrating radiation.
