Iron ore and coal together account for about 72% of cost of input materials in Indian steel plants. Moreover, sourcing iron ore and coal for steel plants is posing multitude of challenges including availability, quality and logistics. At present it is found that high quality input materials are hard to reach and easy to reach ones are of lower quality. Hence efficient utilisation of lower quali...

Aluminium and iron/steel are truly sustainable materials. As a result the global metallurgical industry strives to produce products, which contribute to the global effort by reducing resource use, recycling and reusing materials where possible, and to help create the economic and supply frameworks needed to do this. Aluminium is a material that is infinitely recyclable and remarkably plentiful....

krytyn triplet alkyl esters ayzvsyanydha reactions and lead to the production of acetylene is stable.

Production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. This is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. Initially, unsuitable surface roughness, the friction between rolls and the st...

Introduction Ingot products account for 8.3% of the total crude steel produced in the world. It is produced either by top pouring or bottom pouring of the liquid in the moulds. The increasing demand for quality steels led to the evolution of bottom pouring technology for casting of steel ingots. This process constitutes of a set up involving pouring sprue and runner system to deliver liquid ste...

Calculations were performed to quantify the damage parameters in the leading candidate structural and plasma facing materials when used in magnetic and inertial confinement fusion systems and when irradiated in fission reactors. The structural materials considered are ferritic steel, austenitic steel, vanadium alloy and SiC/SiC composite. Plasma facing materials included beryllium, tungsten, an...

This paper stablishes the model of the integrated batch planning process, and proposes an improved algorithm for this problem. The simulation results of a computerized scheduling system are given to prove the fitness of the model. The steel making casting production process scheduling problem is very difficult to get a good performance solution in practice. The scheduling of steelmaking casting...

The course, technical progresses, and achievements of energy conservation of China steel industry (CSI) during 1980-2010 were summarized. Then, the paper adopted e-p method to analyze the variation law and influencing factors of energy consumptions of large- and medium-scale steel plants within different stages. It is pointed out that energy consumption per ton of crude steel has been almost on...
