g對頭內(nèi)壁橢圓曲線部分拋光，可將工作物固定在有傾斜角200～450的轉(zhuǎn)盤上，用小直徑的風(fēng)動工具裝在拋輪上。沿周長方向由外向部分拋磨。
G. polish the elliptic curve part of the inner wall of the head, and fix the working object on the turntable with an inclination angle of 200-450, and install the small-diameter pneumatic tools on the polishing wheel. It is polished from the outside to the center along the circumference direction.
(10)磨光采用分段打磨，(每段200～300 mm) 磨輪在焊縫上橫向移動，須注意防止長期停在一個地點上，避免局部發(fā)熱產(chǎn)生撓曲。
(10) The grinding wheel (200-300 mm in each section) shall move horizontally on the weld joint. Attention shall be paid to prevent long-term stop at one place and deflection caused by local heating.
2酸洗鈍化工藝
2 pickling and passivation process
(1) 目的在制造過程中，由于加熱，焊接、敲打、搬運等破壞了鋼材表面的鈍化膜，使表面生成水銹及氧化皮，損害了產(chǎn)品的外觀，降低了不銹鋼耐磨蝕性能。酸洗后的表面應(yīng)是干凈光滑，然后作鈍化處理，使加工后的表面重新生成新的鈍化膜(Cr203)，因此酸洗鈍化應(yīng)在拋光后進行，屬于一道工序，
(1) Objective in the manufacturing process, due to heating, welding, beating and handling, the passive film on the steel surface is destroyed, water rust and oxide scale are formed on the surface, which damages the appearance of the product and reduces the wear resistance and corrosion resistance of the stainless steel. After pickling, the surface should be clean and smooth, and then passivation treatment should be carried out to regenerate a new passivation film (CR203) on the machined surface. Therefore, pickling and passivation should be carried out after polishing, which belongs to the last process,
（21酸洗配方的選擇采用以H N03為主的配方。
(21) hn03 is the main formula for pickling.

Preparation of passivation solution: mix 40% ~ 500 / 0 hn03 and 60% ~ 50% H20 at room temperature.
(b)先用有機溶劑（香蕉水、松香水等）不銹鋼表面的局部油漆，然后用工具鏟除焊渣和去除飛濺物。
(b) first use organic solvents (banana water, pine perfume, etc.) to remove the local paint on the stainless steel surface, then use tools to remove slag and remove spatter.
