Title: Manufacture of one-side copper plated stainless steel sheet
Inventor: IRIE YASUSUKE
IPC: C25D5/02
Filed: 1983-05-27
Abstract: PURPOSE:To obtain easily a one-side copper plated steel sheet of high quality by removing nickel and copper electrodeposited by throwing on one side of a steel sheet not to be plated by mechanical polishing and stripping, respectively when the other side of the steel sheet is striked with nickel and plated with copper in order. CONSTITUTION:A stainless steel sheet is degreased and pickled. One side of the steel sheet to be plated is striked with nickel, and nickel electrodeposited by throwing on the other side not to be plated is removed by mechanical polishing. A nickel layer formed by the striking is very thin, and nickel electrodeposited on the side not to be plated is less than nickel electrodeposited on the side to be plated, so said removal by polishing is easily carried out. The adhesion of copper electrodeposited by throwing in the next copper plating stage is made very low by removing nickel, and the copper is easy to strip, so it can be efficiently stripped with a brush roll or the like.

Abstract: PURPOSE:To improve the treating capacity of a sieving device by detecting the amt. of water contained in recovered sand and determining a difference from a set value thereby increasing or decreasing the amt. of the recovered sand to be charged to a sieving device in accordance with said difference. CONSTITUTION:Recovered sand (s) after shake-out is dispensed at every constant rate through a sand dispensing port 2a via a hopper 2, and the amt. of water contained in the recovered sand is detected with a measuring device 12. If the difference between the measured value and the set value set in a control board 13 is small, the amt. of the recovered sand to be dispensed from the hopper 2 is decreased by decreasing the feed speed of a conveyor 3 with a controller 14. If the difference is large, the recovered sand is charged onto the top surface of the sieving screen 6 of a sieving device 4 through a sand feed port 5 while increasing the amt. of the sand dispensed from the hopper 2 by increasing the feed speed of the conveyor 3. Then, the greater part of the recovered sand passes through the meshes of the screen 6 by receiving vibration effect and is recovered through a discharge port 10 into a conveyor 11, by which it is fed to the next stage. On the other hand, the foreign matters such as iron pieces, core shells, iron shots and others that do not pass through the meshes are discharged toward the outside through a discharge port 9.
