A polygonal diagram of the state CaO-SiO2-MgO ternary system was constructed in entire range concentrations solid and liquid initial components, which increases informativeness diagrams metallurgical systems. The obtained results SCS analysis silicate silicide phases duplex SiO2–MgO–CaO : Si–Mg–Ca are scientific basis for optimization blast furnace iron refining processes with smelting slags ma...

The wide-gap aluminothermic rail welds with root opening of 50-70 mm were produced using plain carbon steel rail and non-alloy aluminothermic charge. Mechanical properties and micro-structure of the weld metal and HAZ as well as the impact energy and the fracture toughness of the welds were investigated. The yield and tensile strength of wide-gap welds were about 98% and 95% of the base metal, ...

Deuterium loading of palladium cathodes in Pons-Fleischmann type electrolytic cells has been observed to result in generation of excess heat on several occasions. Metallurgical examination of some of the electrodes showed extensive damage associated with deuterium loading. Surfaces have been found to be covered with large number of impurities. Initiation and sustaining these heat bursts, monito...

Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...
