Title: Production of magnesium silicate
Inventor: TAKAHASHI TERU
IPC: C01B33/22
Filed: 1981-07-10
Abstract: PURPOSE:A slurry that is composed of a raw material of silicic acid, that of magnesia and water is subjected to hydrothermal synthesis to produce magnesium silicate where the raw material of silicic acid and the reaction conditions are specified to give a formed product of high strength and low dry shrinkage without reduction in water repellency. CONSTITUTION:An amorphous raw material for silicic acid, preferably ferrosilicon dust or silicon dust as a by-product in the production of silicon-iron or metallic silicon, a raw material for magnesia and water are mixed to prepare a slurry. The slurry is pressurized and heated under stirring or molded or casted,  then pressurized and heated to effect hydrothermal synthesis to produce magnesium silicate. At this time, the saturated vapor pressure, i.e., the reaction  pressure, is set to lower than 9kg/cm<2> at 179 deg.C. The use of amorphous silica  such as white carbon or kieseguhr as the raw material for silicic acid is undesirable, because the resultant magnesium silicate tends to lower its water  repellency.

Title: Production of ferrite stainless steel sheet of superior workability
Inventor: HARASE JIROU
IPC: C21D9/46
Filed: 1980-08-09
Abstract: PURPOSE: To obtain superior ridging characteristics without annealing of hot rolled sheets by hot rolling a ferrite stainless steel slab under specific conditions then rolling the same as it is to product thickness through one time of cold rolling.  
     CONSTITUTION: A ferrite stainless steel slab is hot rolled at 1,150W900°C thickness central temps., and ≥80% cumulative draft. At this time, the heat treatment is accomplished so as to contain ≥35% draft of one pass. Then, the steel recrystallizes and fines the structure during hot rolling. When it is hot rolled dividedly to plural passes, the recrystallization is difficult but there is the tendency that the recrystallization is easier as the cumulative draft is higher. As the hot rolling temp. is lower, the recrystallized grains during hot rolling are finer, and ridging characteristics improve, but below the lower limit, the recrystallization is insufficient and above the upper limit, the crystal grains after the recrystallization increase. Next, the steel is cold rolled, where it is done as hot rolled to assure the deposition amount of AlN, to improve an π value by maintaining SolAl at above a certain value and to improve cold ductility.
