作业条件
Operating conditions
本工程采用流水线做法进行加工,具体作业顺序如下:
The work of this project is carried out by pipelining.
风管制作
Wind pipe making
金属风管采用钢板制作通风管道,法兰采用型钢加工制作,预制时要注意能不能用错材料,对变径附件(如风口等)连接处应留下一段,待安装时再根据实际尺寸进行下料制作安装。避免返工,法兰制作时应成对进行,避免以后安装时螺栓孔对不齐。通风管道加工
Metal ducts are made of steel plates, flanges are made of profiled steel. When prefabricating, attention should be paid to the use of wrong materials. A section should be left at the connection of variable diameter accessories (such as tuyeres etc.) and then be made and installed according to the actual size. Avoid rework, flange production should be carried out in pairs, to avoid future installation bolt hole alignment.
根据风管的尺寸,选择不同的板材厚度,然后留足咬口余量、进行下料。
According to the size of the duct, choose different thickness of the board, then leave enough allowance for the blanking.
划线方法要严密,做到角直、线平、等分准确、经常检验结合尺寸,达到交圈严格、尺寸正确的目的。
The method of marking should be strict, so that the angle is straight, the line is even, the equal part is accurate, and the combined size is often checked, so as to achieve the goal of strict circle crossing and correct size.
剪切、倒角要正确,尽量减少误差,操作时避免接缝、翻边处重叠。通风管道加工
Cut and chamfer should be correct, minimize error, avoid overlap between joints and flanges.
制作风管及部件时尽量采用咬口连接,因为咬口缝可以增加风管的强度。
Try to use bite connections when making air pipes and components, because the seam can increase the strength of the duct.
根据不同的板材厚度选择咬口的宽度和留量,咬口操作时,避免咬口不实,造成胀裂及半咬口现象。
Choose the width and quantity of bite according to the different thickness of plate. When bite is operated, avoid false bite, cause crack and half bite.
当风管边长过大,其管段在1.2米以上时应采取加固措施视具体情况采用角钢框加固、角钢加固大边,内壁设置加固肋条的办法加固。
When the side length of air duct is too long and the pipe section is over 1.2 meters, reinforcement measures should be adopted, such as angle steel frame reinforcement, angle steel reinforcement of large side, and internal wall reinforcement ribs. 通风管道加工
法兰选用角钢法兰组焊。切断时用型钢切割机加工,在钻床上钻孔后,放在焊接平台上焊接,以保证平直度。
Flange is welded with angle steel flange group. When cutting, it is processed by the section steel cutting machine. After drilling on the drilling machine, it is welded on the welding platform to ensure the flatness.
预制时将相邻风管进行编号,增加功效并减少施工过程中的返工。
During the prefabrication, the adjacent air pipes are numbered to increase efficiency and reduce rework during construction.
风管的规格,尺寸应符合设计要求,当外观质量达到折角平直、圆弧均匀,两端平行、无翘角,风管与法兰连接牢固翻边平整并紧贴法兰。风管加固牢靠、整齐,间距适宜,均匀对称。
The specifications and dimensions of the air duct should meet the design requirements. When the appearance quality reaches a straight angle, uniform arc, two ends parallel, no warping angle, air duct and flange connection firmly flanged flat and close to the flange. The reinforcement of the wind pipe is firm and orderly, and the spacing is suitable and symmetrical.
山东通风管道加工
在安装风管前,障碍物已清理,地面无杂物的条件下进行施工。
Before installing the wind pipe, the obstacles are cleared up and the construction is carried out under the condition of no sundries on the ground.
检查现场结构预留孔洞的位置、尺寸是否符合图纸要求,有无遗漏现象,遗留的孔洞应比风管实际尺寸每边大于100MM。通风管道加工
Check the location and dimension of the pre-reserved holes in the site structure to meet the requirements of the drawings. If there is any omission, the remaining holes should be larger than 100MM on each side of the duct.
作业地点要由相应的辅助设施,如梯子电源和安全防护装置消防器材等。
The place of operation should be provided by corresponding auxiliary facilities, such as ladder power supply, fire protection equipment and so on.
