Title: Method of preventing corrosion caused by use of magnesium hydroxide and continuous cast spray
Inventor: JIYOOJI BII UORUTOMAN
IPC: B22D11/055
Filed: 1994-11-09
Abstract: PURPOSE: To minimize corrosion of a soft steel structure of a casting device by adding magnesium hydroxide to spray water at an entrance of a scale pit and maintaining pH of recirculating water at a specific value. CONSTITUTION: Water to which magnesium hydroxide is added is filtered, is cooled and is returned to a spray system after circulation. Control of alkalinity is executed by maintaining pH of the recirculating water at 8.5 to 9.5. Magnesium hydroxide to be used has most preferably a form of thick slurry. The slurry containing 57% of magnesium hydroxide gives excellent effect. When the pH is adjusted within this range, supplemented acid is neutralized and the corrosion of the soft steel structure is minimized but water becomes scale- formable. Scale depressors, among which a phosphonate depressor is preferable, are used to prevent this and are added to supply water after filtered and cooled.
