Technological Aspects of Low-Alloyed Cast Steel Massive Casting Manufacturing

Abstract

In the paper authors have undertaken the attempt of explaining the causes of cracks net occurrence on a massive 3-ton cast steel casting with complex geometry. Material used for casting manufacturing was the low-alloyed cast steel with increased wear resistance modified with vanadium and titanium. The studies included the primary and secondary crystallization analysis with use of TDA and the qualitative and quantitative analysis of non-metallic inclusions.

Corrosion Behaviour of Low-Alloyed Cast Steel in Diverse State

“…The structure was additionally conducted with use scanning microscope with EDS. The results of microstructure observations were presented in other publications [6,8]. The corrosion test methodology was based on ASTM G-48 00 and position [15], describing the salinity and chemical composition of mining waters in different mining sites of Silesia.…”

“…the mining industry machinery, due to its high operational properties [1][2][3][4][5][6][7][8][9]. Work conditions of such machinery include abrasive wear and corrosion, due to high salinity, with tendency to selective and pitting corrosion [3,4,[10][11][12][13][14].…”

Abrasive Wear of Alloyed Cast Steels Applied for Heavy Machinery

“…Low-alloyed cast steels belong to a very wide range of iron alloys used for responsible heavy-loaded elements and parts [5][6][7][8][9][10][11][12][13][14]. They have found many applications in mechanical engineering, including heavy-duty machines for mining and power engineering (mining machines, crushers, loaders, mills etc.).…”

Size of Non-Metallic Inclusions in High-Grade Medium Carbon Steel

“…Despite existing technological possibilities of obtaining alloys of very high purity, it is not the main aim to achieve the maximum possible effect. Economic conditions, combined with the required steel purity, determine the degree of its purity which must be achieved [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
