background: noise pollution is currently a major health risk factor for workers in industries. the aim of this study was to investigate noise pollution and implement a control intervention plan for blast furnace in a steel industry. methods: the measurement of sound pressure level (spl) along with frequency analysis was done with the sound-level-meter cell-450 . personal noise exposure was perf...

bullwhip effect phenomenon is what reduces the efficiency of the supply chain. the effect occurs when demand changes in the supply chain face with a lot of volatility. so far, several key factors have been identified as causes of this phenomenon. since the steel industry, is the basic one, its efficiency is of great importance. therefore, in this study influencing factors on bullwhip effect in ...

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...

In this paper, we will establish an Eco-efficiency evaluation index system which is based on the characteristics of the steel industry. Using the principal component analysis to eliminate the impact of the evaluation, reduce the workload of the selection of indicators, and establish the DEA model of the iron and steel industry Eco-efficiency. Finally, we test and verify the effectiveness of thi...
