The Eaton (Hopewell) Furnace located near Struthers, Ohio was built in 1802-1803. The first blast furnace west of the Alleghenies and the first industry of any kind in the Western Reserve, it went out of blast circa 1808 due to a combination of factors and fell into ruin. Historical sources on the Eaton are scarce and informational sources are vague, but archaeological excavations carried out i...

In this paper, a new iron-carbon micro-electrolytic filler for wastewater treatment was prepared using the blast furnace dust. The effects of preparation conditions on performance during were investigated. optimal obtained, which provided an experimental theoretical basis use metallurgical dust sludge in fillers. From results treating methyl orange-simulated with fillers different conditions, i...

environmental degradation and economic growth are two important proofs in sustainable developmentwhich are followed by steel industry. in this case, energy and environmental damages as sustainabilitypatterns of environment have been investigated in three different dust collectors to select the mostenvironmentally suitable dust collector for electric furnace. in this article, the consumption amo...

The method of integrating many partial simulators for a complicated system in the consideration of interaction is proposed. Java Native Interface is used to integrate the simulators programmed in different languages. Remote Method Invocation is used to integrate the simulators in different computer environment. By applying the method to the partial simulators on the blast furnace, java-based in...

The high performance concrete is a highly complex material that consists of cement, water, blast furnace slag, super-plasticizer, coarse and fine aggregate. All of the materials play a certain role in the compressive strength of concrete. Combined with the information about age, the compressive strength of concrete is determined by eight attributes: 1. Cement (kg/m!) 2. Fly ash (kg/m!) 3. Blast...

P. Bigoš, J. Kuľka, M. Mantič, M. Kopas , Faculty of Mechanical Engineering, Technical University of Košice, Slovakia This paper describes measuring of time behaviour specified for local stress increments on the blast furnace shell that were performed using strain gauge sensors. These results are compared with values obtained by means of the second specific measuring method. There is also prese...

When tapping a blast furnace, break-through of gas through the taphole at end cast needs to be prevented, both preserve healthy state and prevent dust from escaping into environment. In this paper, two acoustic techniques are presented that can used emissions cast. The first approach is by using spectral analysis recorded data, second uses neural network recognize popping sounds announce slag–g...

The effect of alkali content (% K2O + %Na2O) on the mechanical properties of alkali activated blast furnace paste has been investigated. The paper presents the study on workability, compressive strength, split tensile strength and microstructure of alkali activated blast furnace slag paste specimens prepared by using of sodium silicate and potassium hydroxide solution as activators. The experim...
