· High carbon content of the cast steel leads toa microstructure consisting of primary carbides instead of austenite or one of its transformation products ( pearlite, martensite, etc.) as a primary Dimpled roll forged mill ball, indiing a soft core 6. Usually, the C content of the steel balls is kept between % and %.
The chemical composition of pull rod was determined by optical emission spectrometry (OES) with the result presented in Table analysis at various loion revealed that the pull rod met the chemical composition as per EN 10083 test was conducted to confirm the specified material was supplied by the manufacturer. Table 1.
Grinding wheels with aluminum oxide (corundum), silicon carbide, or ceramic grains are called conventional abrasives. Grain size [ edit] From 10 (coarsest) to 600 (finest), determines the average physical size of the abrasive grains in the wheel. A larger grain will cut freely, allowing fast cutting but poor surface finish.
