A new solution for large-scale scheduling in the steelmaking industry, called Finishing Line Scheduling (FLS), is described. FLS in a major steel mill is a task to create production campaigns (specific production runs) for steel coils on four continuous processes for a one-month horizon. Two process flows are involved in FLS, and the balancing of the two process flows requires resolving conflic...

World labor was estimated to encounter various occupational injuries and health effects shown in iron and steel industries as 37% back pain, 16% hearing loss, 13 % chronic obstructive pulmonary disease (COPD), 11% asthma, 9 % trachea, bronchus or lung cancer, 8% injuries, 2% leukemia. %. Significant decreases in FEV1 and FVC have been associated with increases in occupational exposures to gases...

The equations governing the motion of steel balls and their impact onto shell liners in industrial Semi-Autogenous Grinding (SAG) mills are derived in full details by the authors and are used in order to determine the effective design variables for optimizing the working conditions of the mill and to avoid severe impacts which lead to the breakage of SAG mill shell liners. These design vari...

To enhance the cutting performance of high speed steel(HSS) end mill, single and multilayer coating is applied on substrated HSS mill. Coating material reduces force enhances resistance against abrasive wear. This paper presents physical vapour deposition(PVD) technology machinability PVD coated The mills are fifteen times better than uncoated mill proposed conditions. TiAlN monolayer mills(fut...

We investigated the suitability and applicability of Pseudevernia furfuracea (L.) Zopf for environmental genotoxicity assessment. P. furfuracea lichen specimens were collected from 10 different Pinus species, in every 5 km, starting from around an iron-steel factory located in the central area of Karabük Province up to Yenice Forest. The impact of the pollution sources such as iron-steel f...

The main objective has been to describe different cases of the methanol production from steel-work off gases (Coke oven gas and Basic oxygen furnace gas) and biomass based synthesis gas. The SSAB steel mill in the town of Luleå, Sweden has been used as a basis to analyze four different methanol production cases. The studied biomass gasification technology is based on a fluidized bed gasifier un...

ball mills are common grinding equipment in mineral processing industries. ball wear results from three mechanisms namely impact, abrasion and corrosion. of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. therefore, the aims of this research were to investigate the grinding chemistry influence (slurry ph, solid percentage, water chemistry an...

This paper was aimed to address the modeling and optimization of factors affecting the corrosive wear of low alloy and high carbon chromium steel balls. Response surface methodology, central composite design (CCD) was employed to assess the main and interactive effects of the parameters and also to model and minimize the corrosive wear of the steels. The second-order polynomial regression model...

T C teel remains one of the most important manufacturing industries in Indiana, and the dominant manufacturing industry in Northwest Indiana. The Chicago region continues to lead the U.S. in steel production, accounting for as much as 28% of the total output of steel in the country.1 Currently, steel mill employment accounts for nearly 10% of total employment in Northwest Indiana,2 compared wit...
