IPC: B01D3/14
Filed: 1993-12-24
Abstract: PURPOSE:To improve the firmness and wide applicability of control regardless of the disturbance such as variations in the supply of raw material and its composition by cascade-controlling the deviation of the detected temp. or temp. difference in a tower from the preset temp. or temp. difference against the distillate amt. set from the material balance. CONSTITUTION:The temp. difference obtained from the temp. detectors 31 and 32 provided in a distillation tower 1 with a substracter 103 is used as the measured value and the preset temp. difference as the target value, and both values are outputted to a PID controller 113.

Title: Production of hot-dip galvanized high tensile strength steel sheet of high si content excellent in adhesive strength of plating
Inventor: KIMURA YOSHITAKA
IPC: C23C2/06
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the occurrence of uncoating and to obtain the steel sheet stabilized in grade and having uniform external appearance by specifying oxidation-zone combustion air ratio and performing rapid oxidation at a velocity of a specific value or above in a method for forming an Fe oxide film in a furnace and exerting reduction and heating. CONSTITUTION:A hot-dip galvanized high tensile strength steel sheet having >=0.3% Si concentration in steel is produced. At this time, a steel sheet is subjected to rapid oxidation, where oxidation-zone combustion air ratio is regulated to 0.95-1.10 and also average oxidation velocity in an oxidation zone excluding a preheating zone is regulated to >=30Angstrom /sec, and then to annealing in an atmosphere in which reducing-zone hydrogen concentration is regulated to <=20%, followed by hot dipping. Great changes in oxidation behavior are brought about because of the subtle change in the composition of gas when the above air ratio is less than 0.95, and when it exceeds 1.10, an oxide film is rapidly formed and the adjustment of the desired oxide film of 200-1000Angstrom  cannot be done or is made difficult. When the average oxidation velocity is less than 30Angstrom /sec, oxide film forming velocity is decreased and Si, Mn, and Al are allowed to diffuse in the surface and oxidized and, as a result, the adhesive strength of plating is deteriorated.
