Abstract: PURPOSE:To improve the estimated accuracy of a steel slab temp. by controlling the temp. in a furnace based on information of variable atmospheric gas component in the furnace and furnace temp., etc. CONSTITUTION:The detected values of a CO2 meter 4 and a dew-point hygrometer 5 and the detected temp. of a thermometer 11 in the furnace are given to a controller 12 and an arithmetic unit 13 calculates the atmospheric gas component quantities according to the equations. Further, the furnace temp. distribution in the furnace longitudinal direction is calculated from the thermometer 11 in the furnace and a gas emissivity epsilonG is obtd. and an overall heat absorbing ratio phiCG is calculated. Based on this value, the steel slab temp. in the furnace, furnace temp. distribution and the aimed ejecting temp. are pre-calculated. Then, the temp. rising pattern to the ejection, ejecting pitch and furnace temp. setting value are decided. The controller 12 adjusts fuel charged to burners and controls so that the furnace temp. becomes the setting value.

Title: Cellular concrete painting plate and its manufacture
Inventor: YOSHIDA KAZUO
IPC: B28B1/50
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To simply perform manufacture at a low cost without any problem on a working environment by applying a paint containing a high temperature fusion resin on the surface of unhardened cellular concrete material, and performing autoclave steam curing. SOLUTION: After a paint containing high temperature fusion resin is applied on the surface of unhardened cellular concrete material, autoclave steam curing is performed to form a cellular concrete painting plate. Next, for instance, a water-soluble acrylic resin paint or the like is mentioned as a high temperature fusion paint, and since it is water-soluble, an organic solvent being the object of VOC regulation need not be used. Next, since the high temperature fusion paint is used, the resin component of the paint is fused by heat of the autoclave steam curing to form a paint film, and painting working is simple. Thereby no problem on a working environment of the VOC regulation or the like occurs by using resin containing the high temperature fusion resin, and it can be simply manufactured at a low cost.
