摘要： PURPOSE:To produce an alloy sheet for shadow mask, excellent in adhesion of resist, seizure resistance, thermal strain characteristic, etc., in a manufacturing process of a shadow mask and improved in manufacturing yield. CONSTITUTION:This alloy sheet is an Fe-Ni alloy sheet of proof stress, (18 to 48)kgf/mm elastic limit strength, 0.70-2.5mum average surface roughness, and 0.30-2.0 index of deviation from a roughness curve in a height direction.

摘要： PURPOSE:To obtain the smooth and uniform surface of a hot-rolled article made of titanium or titanium alloy by projecting the high-pressure liquid mixed with polishing material and pickling the workpiece with the mixed aqueous solution of nitric acid and hydroluoric acid. CONSTITUTION:After a hot-rolled titanium hot coil is annealed and pickling- treated, said hot coil is polished to form the state shown in (a) by a belt grinder having a grain particle size of #80, and the state shown by (b) is formed by projecting the high-pressure liquid mixed with the polishing material having a polishing-material mixing rate of 55vol% with a projection pressure of 110kg/ cm , and further the state shown by (c) is formed by pickling said hot coil with the mixed aqueous solution consisting of 200gr/l nitric acid and 30gr/l hydrofluoric acid at a temperature at 25 deg.C, under a spraying pressure of 1kg/cm , and for a spray time of 30sec. Therefore, crack is not generated on the hot rolled article thus obtained even after bending work, and the surface is smooth and uniform, and unevenness is not formed in the grinding trace since the worked surface layer due to the belt grinder and the projection of polishing material is removed through spray pickling.

摘要： PURPOSE:To perform high-efficiency rolling with high rolling reduction and at high speed, by controlling a forward slip so that it exceed the forward-slip limit by detecting the number of revolutions of work roll and the sheet speed of strip at the exit side to compute the foward slip. CONSTITUTION:Forward-slip operators D, E compute the values fT, fB of forward slips from the peripheral speeds UOT, UOB of upper and lower work rolls. An urgent signal is sent by alarm devices H, I when the forward slips fT, fB fall lower than the foward-slip limits fT', fB' previously set by forward-slip limit setters F, G. Then, electric current values of reel motors d, e are controlled through a tension adjuster K so that the foward slips fT, fB exceed the forward- slip limits fT', fB' and the strip tension ratio sigmab/sigmaf us decreased (sigmab: tension at the inlet side, sigmaf: tension at the exit side).
