During the last century the steel industry was influenced by several crises which invoked strong innovation activities in development of new classes of steels. innovation was based on the statement of representative of automotive industry bernhard rolinson who said: “Steel has a long tradition but despite of this its potential from the point of view of material properties is exploited only to 2...

In order to improve efficiency of cutting process in production industry, development of new steel which has good machinablity is desired. The work material which has good surface roughness, easy breakable chip and small tool wear as the good machinablity is expected. And the free-machining steel was developed owning to adding elements which could make the machinablity better. Of all others, le...

At present, iron and steel enterprise develops towards the direction with many procedure, many process, many variety and many specification, and reaches hundreds and thousands of product series and product mix, how to plan, organize and control steel production, production schedule of its product line are key issues. According to the main characteristics of production line of iron and steel ent...

alloy steel, which is versatile in such qualities as grade, property and application, can play an important role in the technical and economic development of the country. the present consumption of the key industrial sector to this strategic material, specified basically as semi- finished products exceeds 100,000 tons per year. however, a rough estimation of the true potential needs, does clear...

The logistic processes in most steel producing plants are very complex. To assist the decision makers in steel producing plants, Incontrol Enterprise Dynamics have developed for and in cooperation with SMS Demag in Germany, a simulator that can be used to rapidly model any steel plant. The Steel Plant Simulator has been built using the software package Enterprise Dynamics® and allows for rapid ...

Iron and steel industry is a crucial basic section for most of the industrial activities. This industry provides the primary materials for construction, automobile, machinery and many other businesses. Furthermore, the iron and steel manufacturing is highly energy consuming. The influence of an efficient process control on the cost and energy reduction and environmental effects in iron and stee...

Cost reduction is one of the methods applied for improving the productivity of organizations. In productivity literature, particularly in nonparametric methods, cost reduction related methods are regarded as input oriented models. This paper presents a Supply Chain Management (SCM) model in which purchasing iron ore and coke from different resources, along with production and distribution of st...

A special instrument has been built to measure the coercivity directly on steel sheets without having to cut samples. It will be used to perform the 8000 coercivity measurements which will be needed during the production of the ll'OOO ton of steel sheets for the LEP dipole magnets. The coercimeter allows local and directional coercivity measurements to be made on a steel sheet with an accuracy ...

In the majority of cases, steel production constitutes the inception of the Supply Chains they are involved just as in automotive clusters or aerospace. Steel manufacturing companies are affected strongest by bull whip effects or other unpredictable influences along the production chain to the customers. Therefore, flexible planning and realisation as well as fast reorganisation after interfere...

The demand of highest possible effectiveness is put on all production processes, while the highest quality is demanded from products. These requirements are particularly justifi ed in the steel industry, due to high cost of technical equipment assembly and production cost. In such conditions continuous processes are of signifi cant meaning, since they facilitate maximum utilization of productio...
