A study of the position effect in cold bending test of hot rolled ribbed bar

热轧带肋钢筋冷弯试验位置效应的研究

Structure steel 20 g is used as a welded joint specimen to perform the cold bending test in different angles .

选用20g焊接试板，在不同的冷弯角下进行冷弯试验；

After welding the materials deterioration in performance , sometimes hot cracks will appear , and cracks will take place in the cold bending test .

焊后材料性能发生恶化，焊缝中有时会出现热裂纹，冷弯试验中会出现冷弯裂纹。

A " position effect " usually occurs in cold bending test of ribbed steel bars , when the bending mandrel is misaligned with the bar surface .

冷弯试验时，钢筋表面相对弯芯放置位置不同，钢筋的变形部位将产生位置效应。

Test results show that it is appropriate to perform a cold bending test as a technology appraisal test before the manufacture of the welded structural parts . It also shows that for cold bending test of carbon steel double-welded joints , the suitable bending angle is 120 ° .

试验结果表明，冷弯试验作为焊接结构件生产前的工艺鉴定试验是合适的，而且，对于炭素钢双面焊焊接接头冷弯试验，其弯曲角度120°为宜。

Described here is the cold bending rupture test on the AC-16C modified asphalt mixture designed using the GTM method with varied gradation , bitumen-aggregate ratio and cement-bitumen ratio .

论述了以GTM设计的AC-16C改性沥青混合料为基础，在级配、油石比、粉油比变化的条件下，分别对混合料进行低温弯曲破坏试验。

The higher the cooling rates , the greater the thermal stress , and the lower the toughness and the cold bending property of test sample .

冷却速度快，试样产生的热应力大，导致冲击韧性及冷弯性能降低。

The cold bending property is one of the important targets for the hot rolled strip , the cold bending test is required inspection item stipulated in the standards .

冷弯性能是热轧中薄板带材的重要指标之一，冷弯试验是标准规定的必检项目，但在实际生产中经常出现冷弯不合格现象。
