Cause analysis about buildup formation of carbon sleeve in continuous annealing furnace for silicon steel Mingsheng He1, a, Shoujun Peng2, Gaifeng Xue1 and Jing Zhang2 1R&D Center of WISCO, Wuhan 430080, China 2Silicon Steel Division of WISCO, Wuhan 430080, China ahms03@mails.thu.edu.cn Key words: silicon steel, continuous annealing, carbon sleeve, causes for buildup formation Abstract: Based on the investigation and study of the topography and composition of the buildups, combined with production process of silicon steel, the major causes of forming buildups of carbon sleeve are analyzed from the factors such as the quality of carbon sleeve, furnace atmosphere, dew point, adjusting steel roll, intermediate steel roll, running speed of carbon sleeve and so forth.
Introduction Annealing furnace is the center of continuous annealing production line for silicon steel strip and key equipment in heat processing for silicon steel.
Generally speaking, graphitization degree of carbon sleeve is more than 60% and carbon sleeve in itself is porous material.

It wastes too much manpower and material, so traffic signal area control system based on ZigBee network is designed.
MCF5208 integrates key structured module, so that we realize the solutions of ZigBee much easier.
The key modules contain 10/100baset Ethernet MAC module with the MII, 8k unified cache /16KSRAM, DDR SDRAM Memory Controller, external bus interface, QSPI, 32-bit timer, many serial connections and BDM/JTAG ports used for test and debugging.

Introduction When developing new dental restorative materials, manufacturers must be able to predict the properties of new materials and their performance in the oral environment.
Also, dental materials are tested to predict the wear performance of new materials before launching to a competitive market [44].
Dental Materials, 2006. 22(8): p. 712-734
'A parallel robot to test dental components and materials'.

For those processes where materials properties are a strong function of temperature, it is challenging to provide equivalent material.
The majority of the industry has settled on hafnium oxide based materials deposited by either metal-organic CVD (MOCVD) or atomic layer deposition (ALD).
film stoichiometry must be controlled as well as, if not better than, the previous generation's oxynitride materials.
