Abstract—The reheating furnace is used to reheat the steel slabs before the hot-rolling process. The supported system includes the stationary/moving beams, and the skid buttons which block some thermal radiation transmitted to the bottom of the slabs. Therefore, it is important to analyze the steel slab temperature distribution during the heating period. A three-dimensional mathematical transie...

Nitrogen doping in combination with the brookite phase or a mixture of TiO2 polymorphs nanomaterials can enhance photocatalytic activity under visible light. Generally, nitrogendopedanatase/brookite mixed phases TiO2 nanoparticles obtained by hydrothermal or solvothermal method need to be at high temperature and with long time heating treatment. Furthermore, the surface areas of them are low (<...

s Some zirconia foams are used as heating elemeht in electrical furnaces. Their creep behaviour has been investigated at high temperature and under low stress. Important visco-elastic behaviour has been observed. It is likely due to recrystallization, which is sensitive to the tetragonal-cubic phase transition and to the stress. I INTRODUCTION Porous and dense zirconia based ceramics have been ...

We develop a method for fabricating very small silica microbubbles having a micrometer-order wall thickness and demonstrate the first optical microbubble resonator. Our method is based on blowing a microbubble using stable radiative CO(2) laser heating rather than unstable convective heating in a flame or furnace. Microbubbles are created along a microcapillary and are naturally opened to the i...

This article presents an optimization methodology for finding the heater settings that provide spatially uniform transient heating in manufacturing processes involving radiant heating. Equations governing the transient temperature and temperature sensitivity distributions over the product are first derived using an infinitesimal-area technique and then solved numerically to calculate the object...

The paper evaluates the performance of cascaded PID controller designs for the temperature control of an industrial heating furnace. From the control theory literature it is clear that ideal PID controller is an obsolete for the control of non-linear processes like temperature. PID controller in cascaded architecture is the best choice compared to conventional single loop control system for con...

In this paper, we argue that servers can be sent to homes and office buildings and used as a primary heat source. We call this approach the Data Furnace or DF. Data Furances have three advantages over traditional data centers: 1) a smaller carbon footprint 2) reduced total cost of ownership per server 3) closer proximity to the users. From the home owner’s perspective, a DF is equivalent to a t...

the design and manufacture of direct smelting reactors depends on the rate of the physico-chemical reactions that occur in the particles immersed into the molten bath. investigation of the effects of the important parameters that influence the smelting rate of the particles that in the furnace are both difficult and expensive if the aimed is to take measure meuts under real practical conditions...
