Dingqiao Metal Testing Center carries out metal performance verification and measurement audit business, metal performance verification projects including chemical analysis, mechanical properties, metallographic analysis, etc. Dingqiao metal testing center through the national quality inspection committee approved, can provide metal composition testing, metal chemical analysis, metal physical properties testing, metal mechanical properties analysis, metal metallographic analysis and other qualification test report.

Metal detection machine is a device that uses electromagnetic field to check the inspected product transmitted on the conveyor line. When the metal signal above the set value is detected, it outputs an alarm mixed with metal or an easy command signal sent by the selector.

​In the production process of gold treatment enterprises, whether metal products and raw materials are qualified or not depends on measuring tools to make a judgment. Whether the indicator value of the measuring tool is correct or not is directly related to the correctness of judging whether the metal product is qualified. We often use metal length gauges which can be divided into vernier gauges, divider gauges, meter gauges and Angle gauges. Vernier measuring tools include: vernier calipers, vernier height calipers, vernier depth calipers, digital calipers and calipers with meter; Sorting card measuring tools include: outside diameter micrometer, thread micrometer, etc. : meter type measuring tools include dial gauge, micrometer, inner diameter scale, etc.; Angle gauge commonly used with universal Angle ruler. Here we introduce several commonly used metal measuring tools:

On December 11, 2019, the State Administration for Market Regulation issued the Notice of Municipal Supervision and Quality Supervision Letter (2019) 2349, including the notice of spot inspection of cold rolled strip reinforcement in 2019. This spot check involved 60 batches of cold rolled ribbed steel bar products produced by 60 enterprises in 9 provinces (municipalities), among which 40 batches of products were unqualified, and the unqualified detection rate was 66.7%.
The KEY TESTING ITEMS OF THE COLD ROLLED STRIP AIDED STEEL BAR ARE MAINLY: PLASTIC ELONGATION STRENGTH, TENSILE strength, elongation after fracture, flexION ratio, maximum force TOTAL elongation, bending, rib midpoint height, RIB spacing, weight deviation, surface mark and so on. The main unqualified items are: plastic elongation strength, tensile strength, flexion ratio, elongation after fracture, etc.
