不同的钢筋的检验规则!

添加时间:2019-01-04      发布人:

作为一个合格的钢市人,对于钢材检验的流程,应该也需要熟知于心的。今天就给大家介绍一下四种不同的钢筋检验时,有哪些规则。
  As a qualified steel market person, the steel inspection process should also be familiar with the heart. Today I will introduce to you four different rules of steel bar inspection.
  热轧钢筋检验:
  Hot rolled steel bar inspection:
  1、组批规则
  1. Group Batch Rules
  以同一牌号、同一炉罐号、同一规格、同一交货状态,不超过60吨为一批。
  With the same brand, the same tank number, the same specification, the same delivery status, no more than 60 tons as a batch.
  2、取样方法
  2. Sampling method
  拉伸检验:任选两根钢筋切取。两个试样,试样长500mm。冷弯检验:任选两根钢筋切取两个试样,试长度按下式计算:L=1.55*(a+d)+140mm
  Tensile test: choose two steel bars to cut. Two specimens, 500 mm in length. Cold bending test: Two specimens were cut from two steel bars and the test length was calculated as follows: L=1.55*(a+d)+140 mm
  低碳钢热轧圆盘条:
  Hot rolled low carbon steel disc rod:
  1、组批规则
  1. Group Batch Rules
  以同一牌号、同一炉罐号、同一品种、同一尺寸、同一交货状态,不超过60吨为一批。
  With the same brand, the same tank number, the same variety, the same size, the same delivery status, no more than 60 tons as a batch.
  2、取样方法:
  2. Sampling methods:
  拉伸检验:任选一盘,从该盘的任一端切取一个试样,试样长500mm。弯曲检验:任选两盘,从每盘的任一端各切取一个试样,试样长200mm。
  Tensile Testing: Choose any plate and cut a sample from either end of the plate. The sample length is 500 mm. Bending test: Select two plates and cut one sample from each end of each plate. The length of the sample is 200 mm.
  在切取试样时,应将端头的500mm去掉后再切取。
  When cutting the sample, 500 mm of the end should be removed before cutting.
  冷拔低碳钢丝:
  Cold drawn low carbon steel wire:
  1、组批规则
  1. Group Batch Rules
济南钢筋批发
  甲级钢丝逐盘检验。乙级钢丝以同直径5吨为一批任选三盘检验。
  Grade A steel wire is inspected by disc. Grade B steel wire shall be inspected in batches of 5 tons of the same diameter with three optional plates.
  2、取样方法
  2. Sampling method
  从每盘上任一端截去不少于500mm后,再取两个试样一个拉伸,一个反复弯曲,拉伸试样长500mm,反复弯曲试样长200mm。
  After cutting no less than 500 mm from each end of each plate, two specimens are drawn, one is repeated bending, the length of the tensile specimen is 500 mm, and the length of the repeated bending specimen is 200 mm.
  冷轧带肋钢筋:
  Cold-rolled ribbed bar:
  1、冷轧带肋钢筋的力学性能和工艺性能应逐盘检验,从每盘任一端截去500mm以后,取两个试样,拉伸试样长500mm,冷弯试样长200mm。
  1. The mechanical and technological properties of cold-rolled ribbed bars should be checked disk by disk. After cutting 500 mm from either end of each disk, two specimens are taken. The length of the tensile specimens is 500 mm and the length of the cold-formed specimens is 200 mm.
  2、对成捆供应的550级冷轧带肋钢筋应逐捆检验。从每捆中同一根钢筋上截取二个试样,其中,拉伸试样长500mm,冷弯试样长250mm。如果,检验结果有一项达不到标准规定。应从该捆钢筋中取双倍试样进行复验。
  2. The 550 grade cold-rolled ribbed bars supplied in bundles shall be inspected by bundles. Two specimens were cut from the same steel bar in each bundle. Among them, the tensile specimens are 500 mm long and the cold-formed specimens are 250 mm long. If one of the test results fails to meet the standard requirements. Double specimens should be taken from the bundle of steel bars for re-examination.
