В Навоийском горно-металлургическом комбинате, использующем в большом количестве детали машин для горных работ, стал вопрос оптимизации составов используемых износостойких хромистых чугунов при сохранении их эксплуатационных характеристик. В работе представлены результаты исследования фазового состава литого сплава, а также влияния термообработки чугуна с высоким содержанием хрома на его структуру и свойства. В качестве операции термообработки применяли закалку по различным режимам и низкий отпуск. Исследование позволило систематизировать известные литературные данные параметров термообработки группы износостойких хромистых чугунов, а также оптимизировать их режимы термообработки для деталей, работающих в горно-обогатительном производстве.

At the Navoi Mining and Metallurgical Combine, which uses a large number of machine parts for mining operations, the issue of optimizing the compositions of wear-resistant chromium cast irons while maintaining their operational characteristics has arisen. The paper presents the results of studying the phase composition of the cast alloy, as well as the effect of heat treatment of cast iron with a high chromium content on its structure and properties. As heat treatment operations, quenching in various modes and low tempering were used. The study made it possible to systematize the known literature data on the heat treatment parameters of a group of wear-resistant chromium cast irons, as well as to optimize their heat treatment modes for parts operating in mining and processing industry.
