在排烟管的制造过程中，镀锌钢板的厚度是根据加工车间风管材料的制造清单来选择的。镀锌钢板从装载架上装载到校平机中，启动后切断钢板端部。送料时检查钢板是否倾斜，试切一块钢板，测量切好的钢板切割线与边缘线是否平直，对角线是否常见。
In the manufacturing process of smoke exhaust pipe, the thickness of galvanized steel plate is selected according to the manufacturing list of air duct materials in the processing workshop. The galvanized steel plate is loaded into the leveling machine from the loading frame, and the end of the steel plate is cut off after startup. During feeding, check whether the steel plate is inclined, try to cut a steel plate, measure whether the cutting line and edge line of the cut steel plate are straight, and whether the diagonal line is common.
根据料单的切割长度和数量输入电脑，启动机器，电脑会主动切割并压筋。有必要重新检查用于剪板的材料，以避免错误。ACL3100等离子切割机用于特殊形状的板材，电动剪刀用于切割零散材料。使用固定式移动剪刀时，钢板应双手支撑，双手离刀口不小于5厘米，用力应均匀适当。
Input the cutting length and quantity of the material list into the computer, start the machine, and the computer will actively cut and press the reinforcement. It is necessary to recheck the material used for shearing to avoid errors. Acl3100 plasma cutting machine is used for special shape plates, and electric scissors are used for cutting scattered materials. When using fixed mobile scissors, the steel plate shall be supported by both hands, and the distance between both hands and the knife edge shall not be less than 5cm, and the force shall be uniform and appropriate.
倒角和咬边连接的风管的咬边宽度和余量根据板材的厚度确定。底切宽度如下表所示。在各种空调通风风管的制造和施工过程中，采用法兰角钢法兰连接方式：方形法兰由四根角钢焊接在一起。划线下料时要注意保证焊接法兰内径不能小于风道外径，并用砂轮切割机将风道用线截取。
The undercut width and allowance of the air duct connected by chamfer and undercut shall be determined according to the thickness of the plate. The undercut width is shown in the table below. During the manufacturing and construction of various air conditioning and ventilation ducts, flange angle steel flange connection mode is adopted: the square flange is welded together by four angle steel. During marking and blanking, pay attention to ensure that the inner diameter of the welding flange shall not be less than the outer diameter of the air duct, and cut the air duct with a grinding wheel cutter.
下料调直后，在钻床上钻铆钉孔和螺栓孔。通风空调系统的孔间距应大于150m，排烟系统的孔间距不应大于100 mm，将冲孔角钢均匀分割，放在焊接平台上进行焊接。焊接时，根据各种标准模具夹紧并压平。焊接后，在台钻上钻螺栓孔；螺栓孔间距与铆钉孔间距相同，分布均匀。
After blanking and straightening, drill rivet holes and bolt holes on the drilling machine. The hole spacing of ventilation and air conditioning system shall be greater than 150m, and the hole spacing of smoke exhaust system shall not be greater than 100mm. The punched angle steel shall be evenly divided and placed on the welding platform for welding. During welding, clamp and flatten according to various standard molds. After welding, drill bolt holes on bench drill; The spacing between bolt holes is the same as that of rivet holes and is evenly distributed.
在整个通风系统的设计和施工中，应该注意的是，排烟管道的质量将直接影响整个建筑的通风和通风功能。因此，山东排烟管道对排烟管道加工技术提出了更高的要求。因此，在主楼的排烟管道工程施工中，尽量选择较大的排烟管道公司，生产设备会更，这样整个排烟管道施工技术才能得到保证，因为生产技术直接关系到排烟管道将来能否使用好。
In the design and construction of the whole ventilation system, it should be noted that the quality of smoke exhaust pipe will directly affect the ventilation and ventilation function of the whole building. Therefore, Shandong smoke exhaust pipe puts forward higher requirements for the processing technology of smoke exhaust pipe. Therefore, in the construction of the smoke exhaust pipe project of the main building, try to select a larger smoke exhaust pipe company, and the production equipment will be more advanced, so that the whole smoke exhaust pipe construction technology can be guaranteed, because the production technology is directly related to whether the smoke exhaust pipe can be used well in the future.
减少有害气体浓度的市政基础设施。选择排烟管道时必须注意。风管生产安装使用的板材、型材等主要成品是否符合现行设计及相关产品标准的规定，并应申请出厂检验证书。材料进场时，应按现行相关标准进行验收
Municipal infrastructure to reduce the concentration of harmful gases. Attention must be paid to when selecting smoke exhaust pipe. Whether the main finished products such as plates and profiles used in the production and installation of air ducts comply with the provisions of the current national design and relevant product standards, and the factory inspection certificate shall be applied. When materials enter the site, they shall be accepted according to the current relevant national standards
