复合钢板检测需要特别注意的事项

来源:http://www.jnjgcg.com/ 日期:2023-04-27 发布人:
复合钢板能够有效结合基材与复材的优势特征,在不改变基材本身性质的前提下,有效克服基材自身的缺点,发挥其优点,增强复合钢板整体的耐磨性、耐冲击性和抗腐蚀性,同时济南复合板厂认为其具有良好的延伸性、成型性等特征。无论是哪种项目的试验,在对复合钢板进行质量检测时,应注意试验结果无效的情况,例如:
Composite steel plates can effectively combine the advantages and characteristics of the substrate and composite materials, effectively overcome the shortcomings of the substrate itself without changing its properties, leverage its advantages, and enhance the overall wear resistance, impact resistance, and corrosion resistance of the composite steel plate. At the same time, Jinan Composite Plate Factory believes that it has good extensibility, formability, and other characteristics. Regardless of the type of test, when conducting quality testing on composite steel plates, attention should be paid to situations where the test results are invalid, such as:
测试抗剪强度时因试样机械加工不当或试验装置使用不当而造成非结合面断裂、弯曲试验时因弯心选错或设备故障等影响试验结果等。当出现此类情况,应重做同样数量试样的试验,或结合实际情况采取其他方案及措施,以保证检测的有效性及科学性。
During the testing of shear strength, non joint surface fracture may occur due to improper mechanical processing of the specimen or improper use of the testing device, and the test results may be affected by incorrect selection of the bending center or equipment failure during bending testing. When such situations occur, the same number of samples should be retested, or other plans and measures should be taken based on the actual situation to ensure the effectiveness and scientificity of the detection.
结合度试验也是复合钢板比较重要的一项检测,可作为剪切试验的一种替代试验对复合钢板相关性能进行检测。由于此试验在卸除试验力后需用肉眼检查试样两侧结合面处是否分离,试验人员技术经验就较为重要,如果对此发生误判,将会直接影响终分离率的计算结果。
The adhesion test is also an important test for composite steel plates, and can be used as an alternative test for shear testing to detect the related properties of composite steel plates. Due to the need to visually inspect whether the joint surfaces on both sides of the sample are separated after removing the test force in this experiment, the technical experience of the testing personnel is more important. If there is a misjudgment in this regard, it will directly affect the calculation results of the final separation rate.

另外还需注意,在制样时如果需要对钢板减薄,需保证复材厚度不得小于3mm,如果复材厚度小于等于3mm时,应只减薄基材厚度。
In addition, it should be noted that if it is necessary to reduce the thickness of the steel plate during sample preparation, it is necessary to ensure that the thickness of the composite material is not less than 3mm. If the thickness of the composite material is less than or equal to 3mm, only the thickness of the substrate should be reduced.
冲击试验时,试样应在靠近基材表面处切取,如果有需要的话,可以在靠近结合面处的基材上取样。对于维氏硬度指标的检测而言,由于复合钢板复材和基材的不同,且可能会产生过渡层等,所以经抛光加工后的试样表面须用相应的腐蚀液腐蚀,使其显示出复材与基材的分界线,如果所需检测的复合钢板具有过渡层和热影响区,还应显示出各区域的分界线。
During the impact test, the sample should be cut near the surface of the substrate. If necessary, samples can be taken from the substrate near the bonding surface. For the testing of Vickers hardness index, due to the difference between the clad steel plate and the base material, and the transition layer may be generated, the surface of the polished sample must be corroded with corresponding corrosion solution to show the boundary between the clad steel plate and the base material. If the clad steel plate to be tested has a transition layer and a Heat-affected zone, the boundary of each area should also be shown.
当根据需要对复合钢板进行超声检测时,应根据复合钢板的声阻抗、表面状态及形状决定是从复板一侧还是从基本一侧进行检测,但如果复板厚度不能满足相关要求时,则必须从复板一侧进行检测。完成检测后可根据检测结果进行等级评定,对于评定不合格的复合钢板供方可以采取相关措施进行处理或修复,修复后重新进行检测,以再次进行等级评定。
When conducting ultrasonic testing on composite steel plates as needed, it should be determined whether to test from one side of the composite plate or from the basic side based on the acoustic impedance, surface state, and shape of the composite steel plate. However, if the thickness of the composite plate cannot meet the relevant requirements, it must be tested from one side of the composite plate. After completing the inspection, the level can be evaluated based on the inspection results. For composite steel plates that fail the evaluation, the supplier can take relevant measures to handle or repair them. After repair, the inspection can be conducted again to conduct the level evaluation again.
对于复合钢板的质量检测还涉及到其他很多指标,每个检测项目都有不同的意义,在不同的应用领域,对于其性能与质量的具体技术要求也不一致,在检测时还应结合实际情况来进行。更多相关内容就来我们网站http://www.jnjgcg.com为您咨询了解吧!
The quality inspection of composite steel plates also involves many other indicators, and each inspection item has different meanings. In different application fields, the specific technical requirements for its performance and quality are also inconsistent, and the inspection should also be carried out based on the actual situation.
