Abstract In the present study, a modified duplex melting process was set up so as to be able produce an EN-GJL-150 gray cast iron from local manganese-rich pig iron. A descriptive statistics showed average Mn and Si content in raw material such that: % = 2.457±0.133 0.682±0.088. The demanganization run monitored cascade of two industrial-scale furnaces: rotary kiln electric arc furnace. perform...

Guinea pig reticulocytes were pulse-labelled with 59Fe bound to transferrin. Haemolysates prepared from these reticulocytes were subjected to rapid (NH1)2SO1 precipitation and then chromatography on an anion-exchange resin. ATP-bound 59Fe was the dominant species in the reticulocyte cytosol; 2,3-bisphosphoglycerate and GTP iron complexes were not detected despite the fact that these were stable...

Pada beberapa tahun terakhir, pertumbuhan industri pengolahan material non fero seperti nikel, alumumium maupun tembaga berkembang sangat pesat. Hal ini secara tidak langsung berdampak terhadap peningkatan limbah metalurgi hasil tersebut. Di Indonesia, slag logam diantarannya Nikel Pic Iron (NPI) merupakan salah satu yang belum digunakan optimal. Disisi lain NPI diketahui mengandung unsur-unsur...

Cast iron (CI) is one of the oldest materials in commercial use. It has excellent compressive strength and is commonly used for structures that require this property, as well as for water and sewer lines. This article explains CI metallurgy and why the understanding of this metallurgy is key to understanding other ferrous materials and alloys. The composition of cast iron (CI) varies significan...

The purpose of the foundry is to provide consumer with blanks for general machine-building (special) purposes which are as close possible size future part in full compliance requirements. competitiveness these products primarily dependent on use efficient and reliable smelting equipment meets necessary cost. replacement high-value ironworks iron steel scrap using induction melting furnaces (ICF...
