Production of the material chamber to a blast furnace

The theses deals with the production of furnace-top hopper. Mainly it is focused on the welding of abrasion-resistant materials and steel for pressure vessels using the FCAW method. These materials are described in detail in the research section, including the additional materials used, the welding methods used and NDT tests used to check the quality of the welds. The practical part then describes the technological process of production. Subsequently, the procedure of welding of the abrasion-resistant steels and steel for pressure vessels, including the developed WPS, is elaborated. The procedure of testing by non-destructive tests of selected combinations of materials with documented test reports and a plan of inspections and tests is also described. Finally, a technical and economic evaluation of production was performed
