如何生产出各方面都合格的方管产品呢?

发布时间:2022-03-31 来源:/

  随着生产技术的提高,方管的产量也随之提高,市场上出现不合格的方管也越来越多,那么如何生产出各方面都合格的方管产品呢?下面给大家详细的先容。
  With the improvement of production technology, the output of square tube also increases, there are more and more unqualified square tube on the market, so how to produce all aspects of qualified square tube products? Here is a detailed introduction.
  方管做冷拉时要采购宝钢的材料,因为宝钢的材料经过级探伤处理,钢材的密度比较好,冷拉加温后,便于成行,将钢材于常温下进行冷拉使产生塑性变形,从而提高屈服强度,这个过程称为冷拉强化,方管一般用于要求高的产品部件有良好的任性和强度,冷拉后表面比较好冷拉原理,
  Party cold-drawn tube do want to buy the material of baosteel, because baosteel level after inspection of materials processing, steel is better, the density of cold drawn after heating, facilitate lines, to cold drawn steel under the interesting and produce plastic deformation, thus improving the yield strength, this process is called cold drawn to strengthen, the square tube is generally used in demanding product components have good capricious and strength, After cold drawing, the surface is better.
  方管的性能指数分析-硬度硬度是衡量金属材料软硬程度的指针,目前生产中测定硬度常用的是硬度法,根据被程度来测定其硬度值,凹模圆角凹模圆角与应力大小和分布有很大的关系,圆角半径大,压边圈压料面积不足,轻易产生失稳皱。
  Square tube performance index analysis - the degree of hardness hardness is a measure of hard and soft metal materials pointer, determination of hardness hardness method is commonly used in current production, depending on the degree is to determine the hardness value, die die fillet corner has a lot to do with stress size and distribution, large radius, pressure to coil material area is insufficient, instability of wrinkle easily.
  而假如圆角太小,材料在变形过程中进进凹模的阻力就会增加,材料不易向内活动和转移,从而增加了传力区的大拉应力,可能导致拉裂。所有的无缝方管要进行力学性能测试,力学性能测试主要分两类,一类是拉伸试验,一类是硬度试验。
  If the fillet is too small, the resistance of the material into the concave die will increase in the process of deformation, and the material is not easy to move inward and transfer, thereby increasing the tensile stress of the force transmission area, which may lead to cracking. All seamless square tubes should be tested for mechanical properties, which can be divided into two categories: tensile test and hardness test.
  在贮存vnsc3775威尼斯城官网的时候,首要需求挑选合适的场所,大家需求思考许多外界要素,钢管的腐蚀性等等,所以场所定要是清洗洁净的,枯燥通风,有害气体呈现的地方,方管都不能呈现,镀锌管杂草等杂物要及时清除,要保持钢材的外表面洁净,脆性问题及相关因素假如库有酸碱盐等容易与钢管发生反响,使钢管腐蚀,所以尽量能够切割开来,假如关于那些较高的金属品,能够思考放进库非常好的保留,依据地理条件。
  In jinan, storage of square tube, priority for selecting suitable sites, we need think about many external factors, corrosion of steel pipe and so on, so place if wash clean, dry and ventilated, harmful gas present, square tube are not present, galvanized pipe weeds and other debris to keep clear of in time, to keep the steel surface is clean, Brittleness problems and related factors if there is acid, alkali and salt in the warehouse, it is easy to react with the steel pipe and make the steel pipe corroded, so it can be cut as far as possible. If there are higher metals, it can be considered to put them into the warehouse and retain them very well according to geographical conditions.
  另外,方管生产工艺流程包括这几道工序:管坯--切断--加热--穿孔--轧管--定(减)径--矫直--切头尾--检验--包装--入库。相关详细内容就来大家网站咨询吧。
  In addition, the square tube production process including the working procedure: tube billet, cutting, heating, piercing, rolling tube set - (minus) diameter, straightening, cutting head to tail, inspection, packaging, warehousing. For more information, please visit .
