Аннотация: Modern electrolyzers are equipment an optimal design, are making of qualitatively materials and are designed for a service life more of than five years. Their productivity and technological efficiency are largely determined by the quality of the electrical contact created between the cathode blocks and steel blooms of the cathode sПоказать полностьюections, for what several technologies are used, one of when based on the use of gas heating, which does not provide the necessary uniformity of heating. In 2014-2018, «ISO», Ltd, together with «RPC MHD», Ltd, was designed, manufactured and implemented installations for pre-heating of cathode sections before subsequent casting of the cast iron, type S-8B, S8Ba, S8BM, OA-300M2, SHpVV, SHpBM, SHpVV-120kA, SHpVV-105 kA. At the moment are put into operation the installations of the type UENB-R-01, UENB-R-02 and UENB-R-03 in Krasnoyarsk, Bratsk and Shelekhovo branches of «ISO», Ltd, in which uses electric heating with the help of tubular electric heaters developed by «RPC MHD», Ltd. Cooperation to improve the designs of installations allowed: to replace gas heating, to achieve the required characteristics in accordance with the technological regulation of production, in particular: the uniformity of temperature distribution on the surface of the cathode blocks and steel blooms in the ranges accordingly (350-410)°C and (430-550)°C, providing a difference of at least 100 °C between the average temperature of the blooms and the average temperature of the cathode blocks for 120 minutes. The efficiency of using of electric heating is confirmed by reliable and long-life operation of the cathode sections in electrolyzers type of S-8B, S8Ba, S8BM, OA-300M2.
