Application of new MQ-P-T technology in white cast iron balls (2）
/dans Billes de broyageThe high chromium cast iron products treated in this paper are made of hot metal with a temperature of 1550 °C, which are cast into 80mm diameter high chromium cast iron grinding balls in a cold mould. The chemical composition of the material is shown in Table 1.
Application of new MQ-P-T technology in white cast iron balls (1)
/dans Billes de broyageAbstract: Fe-2.4C-12Cr high chrome white cast iron balls with a diameter of 80mm was quenched and tempered with water and air by MQ-P-T method, analysis of mechanical properties and microstructure, weaving, alignment, comparison. The strengthening and toughening mechanism of MQ-P-T treated high chromium cast iron was investigated using micro-and microstructure characterization. The results show that […]
Trial-manufacture and application of as-cast low chrome alloy casting balls (3)
/dans Billes de broyageAccording to the designed composition, the molten iron is smelted by induction furnace; after slag removal, temperature adjustment, alloy addition, sampling analysis, and adjusting the composition to be qualified, the molten iron is drawn out at 1500 ~ 1550 °C and is modified by the inner-ladle method, at 1400 ~ 1450 °C, Molten iron is […]
Trial-manufacture and application of as-cast low chrome alloy casting balls (2)
/dans Billes de broyageAccording to the requirements of mechanical properties, after repeated tests, the following chemical composition and scope have been designed: Carbon is the basic element that affects its structure and properties and the important factor that affects the properties of alloy grinding balls. With the increase of carbon content, the EUTECTIC carbides increased and distributed in […]
Trial-manufacture and application of as-cast low chrome alloy casting balls (1)
/dans Billes de broyageChen Mulin. Development & Application of As-cast Low Cr Alloy Ball. Development and application of as-cast low chrome alloy balls have been introduced. Proper chemical compositions and cast technology parameters have been via experiments determined to produce cast balls without heat treatment capable of being put into application in large and medium industrial ball crushers. With […]
