Ductile iron is one of the most important engineering materials, in view of its excellent castability, signifi cantly better mechanical properties and low cost [1, 2]. It represents the fastest growing segment of the iron market. In the medium term, it is to be expected that the market share of nodular iron will level off at 40 % to 45 % [3]. Achieving the full potential of ductile iron require...

Glass cell experiments were conducted to investigate kinetics of iron sulfide and mixed iron sulfide/carbonate scale precipitation in CO2/H2S corrosion. Weight gain/loss (WGL) method was used to investigate the scale formation using X65 carbon steel as substrates. Scanning Electron Microscopy (SEM/EDS), X-ray Diffraction methodology (XRD), X-ray Photoelectron Spectroscopy (XPS), and Electron Pr...

The present paper approaches the development and application of a Discrete Event Simulation (DES) model with a Multiple Criteria Decision Analysis (MCDA) tool for the simulation and sizing of a closed-loop maritime transportation system. This system is responsible for the supply of raw materials, especially iron ore, to a steel plant, and its sizing involves the analysis of the transportation f...

Historical estimates of productivity growth in India's iron and steel sector vary from indicating an improvement to a decline in the sector's productivity. The variance may be traced to the time period of study, source of data for analysis, and type of indices and econometric specifications used for reporting productivity growth. We derive both growth accounting and econometric estimates of pro...

holy basil (ocimum sanctum) is one of the important medicinal plant belongs to lamiaceae family. in order to evaluate the effect of foliar application of iron on iron and chlorophyll contents and photosynthetic parameters of holy basil, an experiment was conducted at research farm of department of horticultural science, shahid chamran university of ahvaz based on randomized complete block desig...

A comparison between the plants of some vital South African industries such as Sugar Industry, the Iron and Steel Industry, the Chemical, Pulp and Paper Industries as well as Power Stations will single out the South African Sugar Factories for one very noticeable item: The absence of supervising and controlling instruments for the manufacturing process and for a number of ancillary processes.' ...

When a steel pilot plant reactor was emptied, and left exposed to the humid summer atmosphere over a weekend, a heavy corrosion deposit formed on the inner surface. Because the process stream contained triflic acid (trifluoromethanesulfonic acid, CF3SO3H), the engineer wanted to determine whether the deposit contained triflate(s) [1]. The brown deposit was ground in a mortar and pestle. The maj...

By: John R. Lanahan Inland Steel Company is the fifth largest steel company in North America and is the largest .producer of steel at one plant. More than 6,000,000 tons/year can be shipped, of which about 60% are flat rolled, products, inland has a series of subsidiaries in warehousing, metal building, and containers which are also steel users. Total corporate sales are in excess of $2 billion...

An important problem in metallurgy of iron and steel is management of hydrated, fine-grained, iron-bearing waste which can be formed as a result of gas scrubbing. The article presents a model of application of converter slurry in a closed-circuit flow system. The correct preparation of slag, namely briquetting with defined additives, allows for application of such slag in the steel-making proce...
