Title: Method of producing of sodium silicate
Inventor: SCHIMMEL GUENTHER DR
IPC: C01B33/38
Filed: 1993-05-04
Abstract: In order to prepare crystalline sodium silicates having a layered structure, a water content of less than 0.3% by weight and an SiO2 to Na2O molar ratio of (1.9 to 2.1):1 from a water glass solution containing at least 20% by weight of solid, the water glass solution is obtained by reaction of silica sand with sodium hydroxide solution in an SiO2 to Na2O molar ratio of (2.0 to 2.3):1 at temperatures of 180 to 240 DEG C and pressures of 10 to 30 bar. This water glass solution is treated in a spray-drying zone with hot air of 200 to 300 DEG C at a residence time of 10 to 25 s and a temperature of the waste gas leaving the spray-drying zone of 90 to 130 DEG C with formation of a pulverulent amorphous sodium silicate having a water content (determined as loss on ignition at 700 DEG C) of 15 to 23% by weight and a bulk density of more than 300 g/l. The pulverulent, amorphous, water-containing sodium silicate is placed in a tilted rotary kiln equipped with means for moving solids and treated therein counter-currently with flue gas at temperatures of more than 500 DEG C to 850 DEG C for 1 to 60 minutes with formation of crystalline sodium silicate. The rotary kiln is insulated here in such a manner that the temperature of its outer wall is less than 60 DEG C. Finally, the crystalline sodium silicate leaving the rotary kiln is comminuted by means of a mechanical crusher to particle sizes of 0.1 to 12 mm.

Inventor: GENIES BERNARD
IPC: F27B14/10
Filed: 1982-12-07
Abstract: This invention relates to the production of refractory linings. According to the method, the lining formed by refractory materials is heated to a temperature sufficient to cause the sintering of the materials on at least an internal surface of the said lining. To provide this heating action, a flame is produced from a fuel gas and oxygen, within a partially closed volume close to the lining which is to be sintered, and a diluting gas is injected between the flame and the lining, at least during the first part of the rise in temperature. The method is applicable to the sintering of the linings of vessels utilized in metallurgy, in particular of induction furnaces.
