4．切割下料
Cutting
下料前，应检查材料表面质量，涉及局部凹陷和划伤情况，表面质量合格才干下料，如复层表面有局部伤痕、刻槽等，则应修磨，修磨深度不应超过复层厚度的30%，且不大于1mm，修磨范围的斜度至少为1：3，且应有良好的圆滑过渡。

，复层面应朝上，对于复合板总厚度不大于60mm，采用等离子直接切割；对于复合板总厚度大于60mm，应将割缝处的复层剥掉，然后用氧-乙炔切割，割口两边应涂保护涂料，如白垩粉等，以免飞溅物影响复层表面质量。切割前，应进行标记移植（先在复层用记号笔移植，待工件翻身后再在碳钢基层上移植并打钢印）。
During cutting, the cladding surface shall be put up. For the total thickness of the clad plates not more than 60mm, the plasma cutting shall be used; for the total thickness of the clad plates more than 60mm, the cladding that on the cutting seams shall be peeled off firstly and then use the oxy-acetylene to cut them, the area adjacent to the cutting area shall be protected by painting chalkiness powder to avoid the spatter dropping on the cladding surface. Before cutting, the markings shall be transferred (firstly, transfer the markings on the cladding surface, secondly, transfer the markings on the carbon steel after the plate is overturned.)
，严防刨边机机油污染复层表面，刨边机夹具处应用不锈钢垫板隔开。
When use planer machine to process the groove, the oil from the machine shall be strictly controlled to avoid it to drop on the cladding surface, the clamp of the planer machine shall be separated by stainless steel pad.
-乙炔切割的坡口，需用砂轮或风铲打掉熔渣，并去除1～，打磨过碳钢的砂轮片不得用来打磨复层（打磨碳钢的砂轮片应当用油漆做好标记，如用红色油漆）。
The grooves which are cut by plasma or oxy-acetylene shall be ground with grinding wheel or wind shovel to remove the slag. And the 1~ of cutting HAZ shall be removed. The piece of the grinding wheel which grinds the carbon steel shall not be used for grinding the cladding (The piece of the grinding wheel which grinds the carbon steel shall be marked by paint, such as red paint).
：为了保证环缝组对错边量，对筒体展开长度应严格控制，相邻两筒节长度偏差不大于5mm；筒体展开长度应按封头实测外周长换算成内径，以内经为基准计算展开长度。对于厚壁容器要考虑卷制伸长量，具体按《厚壁容器制造工艺规程》拟定。
The requirements for the cutting dimension of the shell: In order to ensure the misalignment of the circumferential welds during assembly, the length of the open up shell shall be strictly controlled, and the deviation of two adjacent shell length shall be not more than 5mm; the length of the open up shell shall be conversed to inner diameter according to the true measurement and calculate the true open up length shall base on the inner diameter of end. For the thick wall vessel which shall regard the elongation, the specific requirement shall be performed according to <<The procedure specification of the thick wall vessel fabrication>>.
：按有关文献规定及具体产品工艺文献规定放余量下料。
The requirements of the cutting dimension for cone: it shall be performed according to the requirements of the corresponding document and specified process document of equipment.
坡口加工后，基层表面弱酸实验，具体按《复合板坡口表面酸蚀实验流程》。
After the groove processed, the backing shall be tested by weak acid and the specific requirements according to << the procedure of clad plate groove surface acid test >>.
5．冷作成形 Cold forming
筒体一般采用冷卷成形；锥体宜采用冷压成形。
Shell is usually formed with cold rolling; cone is usually formed with cold pressing.
卷板前必须将卷板机上辊表面的铁屑、毛刺、锈斑、油污等杂物清除干净，并用砂纸打磨光滑。
Before rolling the plate, the iron, fragments, rust, oil and other contaminations on the surface of roller shall be removed cleanly and ground smoothly by sand paper.
，以保护复层表面。
The roller of the rolling machine shall be covered by plastic film or thinner stainless steel to protect the surface of the cladding.
卷制前应先压头，压头应在油压机或卷板机上进行。如用油压机压头，在模具与复板之间应衬垫8～10mm厚不锈钢板。对于厚壁容器是否加放压头量以及成形前的准备，按《厚壁容器制造工艺守则》规定执行。压头曲率用样板控制，样板弦长不小于300mm，并符合相关标准规定。
The head shall be pressed before rolling, and pressing head shall be done on the oil pressing machine or rolling machine. If using the oil pressing machine, 8~10mm thickness stainless steel shall be put on between the mould and clad plate. For the thick wall vessel, whether the measure of the head shall be set or not and the preparation before formation shall be according to <<Thick wall fabrication procedure specification>>.The curvature of the pressing head shall be controlled by former, and the string length of the former shall be not less than 300mm and shall comply with the requirement of corresponding regulation.
，在同一段区域不宜多次反复碾压。
The down pressing measurement of up roller shall be controlled during rolling, and too many times on the same area is forbidden.
，对于厚度大于60mm的锥体，应提成3片压制。压制前，在扇形板片上复层面画等分素线。压制时，复层与上模间应用8～10mm厚不锈钢板条垫好，然后沿素线压制。大、小口曲率用样板控制。
The cone shall be divided to two or three pieces for cold pressing forming. For the thickness more than 60mm, the cone shall be divided to three pieces. Before forming, cladding surface of the sector shall be drawn with line. During forming, the cladding and upper mould shall be filled up with 8~10mm thickness stainless steel, and the cladding shall be pressed along the line. The former shall be used to control the big and small vent curvature.
6．热成形或温成形
Hot forming or warm forming
凸形封头整体宜采用热成形或温成形。不得采用旋压成形。成形过程中，重要保证基层的力学性能和复层的耐腐蚀性能。如采用整体冷压成形应经工艺责任工程师批准。
The gibbose head should be adopted hot forming or warm forming and the spin pressure forming is forbidden. During the forming, the mechanical properties of the backing and the corrosion resistance of the cladding shall be mainly ensured. In case of adopting cold forming, the procedure shall be approved by process responsibility engineer.
，热成形时，升温速度应较同等厚度的碳钢或合金钢慢。冲压时，为了避免温差应力过大而影响了两种不同金属间的结合强度，还应使模具有一定的预热温度。具体应按《封头数据表》规定执行。热成形一般采用控制温度成形，不此外热解决。对于特殊材料需要单独热解决的应制定具体工艺。
For the austenitic stainless steel clad plate, hot forming should be used. The speed of the temperature raising shall be slower than the carbon steel and alloy steel which are with same thickness during hot forming. During punching, in order to avoid the big temperature difference stress to affect the coalescent strength between two different metals, the mould shall be with definite preheat temperature. The specific requirements shall be performed according to <<Head Date Sheets>>. Hot forming usually adopts temperature controlled to shape and other heat treatment is not need. For the special materials which need single heat treatment, the specific procedure shall be prepared.
