| description | Rolling rings as an important element of the rolling mill belong to the category of replaceable equipment, the quality of performance of which affects a number of operational characteristics, as well as the quality of rolled products. The material from which the rolling ring of the stand No. 7 is made must have the appropriate properties capable of perceiving high thermal loads for a long period of time without destruction, chipping and significant development of calibers. In this regard, there is a need to select the optimal option for the manufacture of rolling rings that can withstand such loads for a sufficiently long period of time. The study of the causes of destruction of the rolling ring 450×242×100 mm of high-speed steel, used at OJSC «BSW – Management Company of the Holding «BMC» in the cage number 7 mill 150 rolling shop. The results of metallographic studies of the microstructure and chemical composition of fragments of the destroyed rolling ring are presented. A detailed study and comparative analysis of the chemical composition and microstructure of samples of similar rings made of high-speed steel from two different suppliers, which showed high results in durability during operation, was carried out. |
