Abstract: PURPOSE:To enable production of a crystalline silicic acid compound, capable of suppressing adhesion to a furnace core pipe and carrying out stable continuous operation by directly feeding a hydrous silicic acid compound to a high- temperature region in externally heating type horizontal rotary pipe furnace whose furnace wall temperature is not lower than a crystallization initiating temperature. CONSTITUTION:In a process for producing a crystalline silicic acid compound by subjecting hydrous silicic acid compound to heat treatment, a hydrous silicic acid compound having

Abstract: PURPOSE:To suppress the formation of the deposit layer and agglomerate in a device and improve the productivity by burning a powdery amorphous silica compd. having a specified content of water. CONSTITUTION:A siliceous compd. soln. (e.g. silicate soln.) contg. 28-95wt.% (wet basis) water is dried at 170-400 deg.C by spray drying, etc., to obtain a powdery amorphous siliceous compd. contg.

Abstract: PURPOSE:To inhibit the growth of a deposit layer in a heating furnace and to obtain a stable silicate compd. by heating a powdery hydrous silicate compd. in the furnace packed with a granular rigid body. CONSTITUTION:A heating furnace is packed with a granular rigid body having 3-100mm diameter, 2-10g/cc density and spheroidicity of >=0.85 so that 5-70% rate of packing is attained. A powdery hydrous silicate compd. is fed into the furnace and heated at 250-500 deg.C for >=30sec to obtain the objective silicate compd. represented by the formula xM2O.ySiO2.zM'O (where M is Na and/or K, M' is Ca and/or Mg, 0.5

Abstract: PURPOSE: To provide an amorphous silicic acid compd. having a prescribed water content with a compact drier without causing sticking or producing an aggregated lump. CONSTITUTION: An aq. soln. of a silicic acid compd. is mixed with an amorphous silicic acid compd. and the resultant mixture is dried with a drier having stirring mechanism to produce the objective amorphous silicic acid compd. In other way, an aq. soln. of a silicic acid compd. is mixed with an amorphous silicic acid compd., the resultant mixture is granulated and this granulated mixture is dried with a drier having stirring mechanism to produce the objective amorphous silicic acid compd.

Abstract: PURPOSE:To provide the device which displays a Gantt chart and the occurrence prediction chart of a manual operation process. CONSTITUTION:The start time and end time of a future process are predicted on the basis of the contents of an operation result data base 4a which controls past operation results, process operation information which is inputted sequentially, and the contents of the production schedule file 4d, and then displayed on a CRT 8. Predicted values regarding manual operation are stored 10 a manual operation prediction file 4b and also displayed on the CRT 8.
