According 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 […]
According 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 […]
Chen 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 […]
In order to make use of the MQ-3 ball tester for the impact fatigue test, we produce an 80mmm size ball. 2.1 Smelting and casting The melting equipment is a medium frequency coreless induction furnace with a nominal capacity of 850kg, and the pouring equipment is a 1-ton tilting type crane ladle.
In recent years, high chromium metal mold casting grinding ball has been widely used. In cement, electric power and mining industry and in the water, mud production, replaced, the pebble ball has achieved significant social benefits, market demand, and increasing. How to ensure the quality and meet users’ needs, production process control has become a […]
