对我影响最大的一个人H-beam production process
With the development of industrialization and the arrival of information age, more and more advanced equipment for production of the liberation of a large number of labor, create more social value, increa the production safety coefficient at the same time. In terms of welding h-beam production, h-beam group to the emergence of machine and the u of gantry submerged arc welding welding technology has brought significant technological innovation.
Since h-beam automatic group on the machine put into u, due to the decisive role of h-beam technical parameters to ensure become indispensable in the group of process equipment. H-beam automatically t to the preferred cutter blanking machine work, after flat steel (including flange plate and web plate) in the group of orbit of the machine, with a group of machine clamping device for wing plate and web plate initial clamping positioning, the active entry table input artifacts to host, host prior to adjust benchmark web and flange size, namely artifacts can be accurate positioning spot welding, automatic cycle button, then the head location and spot welding, and then u some good h-beam gantry crane hanging from the group, after the machine into the next procedure. H-beam t of machin
e is one of the important equipment, ensure the h-beam technical parameters is mainly compod of four large transmission mechanism, specific include: web roller drive mechanism, wing on the two positioning clamping mechanism, about web positioning clamping mechanism and input/output roller transmission mechanism, etc. Pressure on web wheel transmission mechanism adopts hydraulic clamping, u by hydraulic cylinder transfer of power is the highest roller, roller center external u V groove design, to ensure that regulations within the scope of different width of accurate positioning and automatic web for accurate, do not need to ret every time; On roller thrust bearing on inside, can not only convenient for h-beam transmission on the roller table, still can make the h-beam web can fully contact with wing during transmission, for guarantee of h-beam ction height size, played an important role.
Through a large number of instances prove that operation, including automatic h-beam group on the machine and gantry submerged arc welding, a large number of the application of advanced instruments and equipment, saving the cost and reduce the time limit for a project, to ensure the quality of reliable, ensure no potential safety hazard and so on. Steel alloy steel, high-quality steel bar mill rebuilding project of 3000 t welded h-beam applied the new equipment, h-beam welding qualified rate reached 99%, greatly improved the production quality and reliability, and productivity in一边一边造句二年级
cread five times, and the whole project of the welding process in the traditional group saves about $200000, created a considerable economic benefits.

H型钢制作工艺
随着工业化的发展和信息化时代的到来，越来越先进的生产设备解放了大量的劳动力，创造了更多的
社会价值，同时增加了生产安全系数。在焊接H型钢制作方面，H型钢组对机的出现和门式埋弧焊的使用给焊接技术领域带来了重大的技术革新。
自从H型钢自动组对机投入使用以来，由于其对H型钢技术参数保证的决定性作用而成为组对工序中必不可少的设备。H型钢自动组对机工作首选切割机下料，将平整后的钢板（包括翼缘板和腹板）吊放进组对机轨道上，用组对机的夹紧装置进行翼板和腹板初步夹紧定位，由主动输入辊道将工件输入主机，主机上事先调整好腹板和翼板基准尺寸，也就是可将工件准确定位点焊，然后自动循环按钮，进行头部定位点焊，然后将点好的H型钢用龙门吊吊离组对机后，进入下一道工序。H型钢组对机是保证H型钢技术参数的重要设备，主要由四个大型传动机构组成，具体包括：腹板上压轮传动机构、翼板左右定位夹紧机构、腹板左右定位夹紧机构及输入输出辊道传动机构等。腹板上压轮传动机构采用液压夹紧，使用的动力由液压缸传递至上压轮，上压轮外部中心处采用V型槽设计，能确保规定范围内不同宽窄的腹板定位准确和自动对中准确，不需要每次重新调整；上压轮内部采用推力轴承，不仅能方便H型钢在辊道上传输，还可使H型钢腹板在传输时能够充分接触到翼板，对于H型钢截面高度尺寸的保证，起到了重要作用。
通过大量的操作实例证明，包括H型钢自动组对机和门式埋弧焊在内大量先进的仪器设备的应用，节约了成本，减少了工期，保证了质量的可靠行，确保无安全隐患等。韶钢合金钢、优质钢棒材轧机改建工程的3000t焊接H型钢应用了新型的仪器设备，H 型钢焊接合格率达到99%，大大的提高了制作质
量和可靠程度，生产效率提高了五倍，而且整个项目较传统组对焊接工艺节省了约20万元，创造了可观的经济效益。
