This article considers the problem of the rise in temperature of the windings of an induction motor during start-up. Excessive growth of thermal stresses in the structure of a cage winding increases the probability of damage to the winding of the rot

During the steel production process, nearly twice as many input materials are used as compared to finished products. This creates a large amount of post-production waste, including slag, dust, and sludge. New iron production technologies enable the r

Emergency motor switch-on happens occasionally while operating a doublesquirrel- cage motor at full supply voltage with the rotor blocked (e.g., in coal mills). After releasing the blockage, the by now heated motor is started up again. However, the m

This article discusses the thermal and mechanical exposure of the starting cage of a double-cage induction motor rotor during start-up. Damage to the starting cage is the most common cause of failure of a double-cage winding during long start-ups. It

A procedure for evaluating the susceptibility of raw materials for the process of sintering of iron-ore mixes is presented. The procedure relies on the evaluation of the amount and quality of the finest grain fraction. The method is based on determin

As a result of manufacturing processes, steelworks plants produce large amounts of waste materials. Currently in modern steelworks the most of waste is utilized in the same steelworks and passed to external customers or it is reused as a feed for oth

The rotating disk methodology has been used for examination of the reduction of FeO from CaO-FeO-SiO2 liquid slags (20 and 60 pct FeO) with a CaO/SiO2 ratio equal to 0.66 and 1.27, in the temperature range 1350 °C to 1420 °C. It has been found that
