The factors influencing the formation of external and internal defects in 4Kh5MFS quenched steel piercing mandrels are investigated. During the formation of vessel cavity, the solid mandrel is found to undergo nonuniform heating along its length with a temperature of about 350°C at the base and about 600°C in the nose part. A high temperature (600°C) is shown to cause the formation of a 0.6-mm-thick scale layer and a 0.4-mm-thick decarburized layer in the nose part. Subsequent external water cooling of the mandrel makes it possible to eliminate the influence of temperature on the further growth of a ferritic ring; however, thermal stresses form in this case and induce defects in the form of flaws and cracks. The hardness along the solid mandrel length after piercing 1000 vessels differ by more than 2 times: it is 20 HRC in the nose part and about 40 HRC at the base. A water-cooled mandrel with internal cooling has been designed to form high-quality vessel cavity. The internal cooling of the mandrel is found to decrease the heating temperature of the nose by more than 4 times and that of the base by 2 times. The decrease in the mandrel temperature during the piercing of vessels is shown to eliminate the formation of a decarburized layer and flaws on the mandrel surface almost completely and to stabilize the hardness in a range of 45–50 HRC along the mandrel length.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 7","pages":"1783 - 1788"},"PeriodicalIF":0.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multifactorial experiment has been conducted to study the influence of grinding modes and grinding wheel materials on the surface roughness on processing 95Kh18 steel. The surface roughness was assessed using parameter <i>Ra</i> and a portable profilometer model MarSurf PS1. Based on the obtained data, it is possible to select the optimal cutting mode based on the required surface roughness. To achieve a stable quality of the processed surface (<i>Ra</i> = 0.63 μm), it is necessary to use a diamond wheel at cutting speeds from 10 to 25 m/s and low feed. The obtained regression equations show that an increase in the cutting speed or a decrease in the feed leads to a decrease in the surface roughness. The main provisions of metal cutting technology and mechanical engineering technology have been used.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 7","pages":"1495 - 1500"},"PeriodicalIF":0.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
