The dynamic behavior of an industrial tunneltype furnace is of the fundamental importance for the quality of the processed products. The knowledge of the furnace dynamics can make the control of the system easier as well as it can eliminate certain operational problems. The various subsystems existent in a tunnel-type furnace are usually controlled by conventional techniques and independent con...

*Tenova LOI Italimpianti, Italy, **Centro Sviluppo Materiali SpA, Italy ENVIRONMENTAL concerns and rising prices of fossil fuels have focused the steel industry’s attention on minimising emissions and improving heating efficiency in reheat furnaces. Additionally with the rise in competitiveness within the world steel market product quality can be a key strategic factor to gain a market, a facto...

Abstract Fe–26Si–9B alloy is a promising high temperature phase change material (HTPCM), due to its heat of fusion, small volumetric change, abundance, and low cost. Additionally, graphite has been identified as candidate for use container this alloy. In study, the feasibility using HTPCM investigated in pilot-scale. Specifically, 4–5 kg master alloys were melted crucibles an induction furnace,...

Plastic strain behavior in the transversal direction to axis of loading has often been underestimated concrete design and its strength performance. However, as this article demonstrates, it is fundamental define viability using a certain composition real applications. In study, 15 Self-Compacting Concrete (SCC) mixtures produced with Recycled Aggregate (RCA) Ground Granulated Blast Furnace Slag...

Hydrogen sulfide (H$) has long been associated with the cause of corrosion damage and sulfide stress cracking (SSC) in high strength steels and high hardness weldments used in oil and gas production, petroleum refining, and petrochemical/chemical processing. Other applications where sulfide species have produced environmental cracking include heavy water production, electric power, marine appli...

Corrosion cracking of reinforced concrete caused by chloride salt is one of the main determinants of structure durability. Monitoring the entire process of concrete corrosion cracking is critical for assessing the remaining life of the structure and determining if maintenance is needed. Fiber Bragg Grating (FBG) sensing technology is extensively developed in photoelectric monitoring technology ...

abstract fruit cracking of pomegranate is a phenomenon that is shown at most growing zones of the world. pomegranate cracking is the main obstacle for production and export, and have a lot of annual economic damage, the present study has been done about pomegranate trees. the purpose of this research is surveying the decreasing of pomegranate cracking and increasing the fruit quantities and qua...

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...

Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...

This study investigated the effect of oxygen and micro-cracking on the flotation of low grade nickel sulphide ore. The ore treated contained serpentine minerals which have a history of being difficult to process efficiently. The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential. The desired effect of micro cracking the ore is that the nickel ...
