Not only the quality of the imported bearing workpiece is poor, but also the workpiece resistance to crystal corrosion is reduced. When the imported bearing workpiece is severely overheated, the grain size is coarse; together, the amount of 8 iron wire in the steel is added; the hot working function of the workpiece is easily deteriorated. lcrl8Ni9Ti stainless steel When the accompanying body or the flange member is overheated; it is prone to the appearance of orange peel.
To this end; propose ways to avoid such as (1) strict control of the lcrl8Ni9] ri stainless steel box, the casting temperature of the flange parts and the heating and holding time; avoid the workpiece overheating to make the workpiece coarse grain defects.
(2) Forging production of workpieces; such as casting ratio. 斩 露 露 露 撸 撸 惨 惨 惨 惨 鱿 鱿 鱿 鱿 ё橹 ё橹 荩 荩 κ κ ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮 ぜ驮
(3) Heat treatment of imported bearing workpieces should not be too high; the heat preservation time should not be too long; the heating temperature should not be higher than 1150"C; the heat preservation time should be calculated at 1 l_5min/mm.
(4) The coarse workpiece arranged for the overheating of the attack; the method of changing and forging the refined grain can be used to eliminate the shortcoming; avoiding the appearance of the orange peel appearance when the workpiece is cold deformed; improving the appearance quality of the workpiece
