Title: Steel sheet coated with zinc or zinc alloy by hot dipping and having superior blackening eresistance
Inventor: SUZUKI MASARU
IPC: C23C28/00
Filed: 1985-08-29
Abstract: PURPOSE:To inhibit the progress of the blackening of a steel sheet coated with zinc or a zinc alloy by hot dipping by thermally decomposing a cobalt salt on the steel sheet immediately after the hot dipping so as to form a cobalt oxide film. CONSTITUTION:A steel sheet is coated with zinc or a zinc alloy by hot dipping. Before the resulting zinc or zinc alloy layer is solidified, cobalt nitrate and/or cobalt chloride is blown on the layer in the form of an aqueous soln. or the like and decomposed by the heat of the hot layer to form a cobalt oxide film of CoO, Co3O4, CoAl2O4 or a mixture thereof. The cobalt oxide film acts as a barrier for inhibiting the progress of blackening. A chromate film is further formed on the cobalt oxide film as required so as to enhance the effect of the cobalt oxide film.

Filed: 1988-07-29
Abstract: PURPOSE:To form ice crystals without supercooling solution for saving energy in a storage system for ice crystals which are formed by mixing a very small amount of ice crystals into the cooled solution after it reaches around its freezing point. CONSTITUTION:Solution in a heat storage tank 1 is circulated through a suction port 6, a pipeline 7, a pump 4, a cooler 2, a pipe line 9, and a control valve 5, and cooled by the cooler 2. At this time, a portion of the solution flows into a nucleus ice storage 3 through a branch line 12, and then return to the cooler 2 again. When the solution reaches its freezing point and a temperature sensor 14 is put in action, the control valve 5 is closed, and the solution is circulated only between the ice storage 3 and the cooler 2 to cool it until ice crystals are formed. When an ice sensor 15 detects the formation of ice crystals, and the control valve 5 is opened, the solution in the heat storage tank 1 is circulated again. At this time, the ice crystals in the seed ice storage 3 play a role as the nucleus in separating ice crystals from the solution since the solution has reached its freezing point, so that energy can be saved.
