in this study, vanadium recovery from the steelmaking converter slag was studied. salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. ground slag was roasted after mixing with determined quantities of sodium carbonate. the effect of time and temperature of roasting and sodium carbonate content were studied. the optimum temperatu...
Many researchers have reported positive effects of converter sludge and slag, two by-products in Isfahan iron melting factory. In this work, the optimum rate of application and the availability of some essential elements (for plant growth) in the converter sludge and slag for corn were investigated. The converter sludge contains about 64% Fe ІІ and ІІІ oxides and some other essential elements f...
Application of slag and converter sludge, major by-products of Esfahan Zob Ahan factory, to enrich two organic amendments for corn nutrition, was investigated. Farm manure and its vermicompost mixed with different rates of slag and sludge were incubated in 3 Kg pots at field capacity moisture and home temperature for three months. The applied rates of slag and sludge were 0, 5 and 10 percent ...

The most common steel-making process in the world is the Lintz-Donawitz converter. During operation, a slag foam is created to improve the converter performance. Problems arise when the foam level exceeds the height of the vessel and overflows, causing metal loss, process disruption and environmental pollution. The goal of this study is to design a model-based algorithm exploiting real-time pro...

Oxygen top-blow converter is the main equipment in steelmaking. Because the support system of converter bears total weight of the converter and its accessories, and meanwhile transfers tilting torque from tilting mechanism to converter, it is the most important part of converter machinery. The joint equipment which links the converter with the support ring is the key part in the support system,...
smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...
The paper shows the results of a study influence cut-off method slag by using destructible plugs on quantitative indicators redistribution and metal in steel ladle during tapping operation from converter. laboratory setup simulates real 160-ton industrial top-blown oxygen converter, at scale 1:18 has been used to fulfill study. Water was chosen as liquid imitator, machine oil for with parameter...
