Ductile hlau tau tsim sai heev rau hauv cov khoom siv hlau cam thib ob rau grey hlau thiab dav siv. Lub npe hu ua "hlau es tsis txhob steel" feem ntau yog hais txog cov hlau ductile.

Nodular cam khwb cia hlau yog tau los ntawm spheroidization thiab inoculation kev kho mob, uas zoo txhim kho cov neeg kho tshuab zog ntawm cam khwb cia hlau, tshwj xeeb tshaj yog cov ductility thiab toughness, thiaj li yuav tau siab zog dua carbon steel.

Ua tsaug rau koj xaiv peb cov khoom. Peb tos ntsoov yuav pab koj nrog qhov zoo tshaj plaws ntawm peb lub peev xwm.

Ductile cam khwb cia hlau lim dej npog yog ib yam ntawm cov khoom siv hlau, ductile cam khwb cia hlau los ntawm spherization thiab yug me nyuam ua tau pob graphite, zoo txhim kho cov neeg kho tshuab engergy ntawm cam khwb cia hlau, tshwj xeeb tshaj yog txhim kho cov yas thiab toughness, yog li tau txais lub zog siab dua carbon hlau. Ductile cam khwb cia hlau yog ib qho khoom siv hlau casting uas tau nthuav tawm hauv xyoo 20^th century, which is close to steel, which is based on its excellent performance and has been successfully used to create some parts that are complex, strong, resilient and wear-resistant, Ductile cast iron has been rapidly developed second only to grey cast iron and is widely used in cast iron materials. It is called”iron generation steel”, mainly ductile iron, Ductile cast iron is divided into circular and square, in urban road management, generally adopt round manhole cover, because round manhole cover is not easy to tilt, can be better protect the safety of pedestrians and vehicles, using the circle manhole cover is mainly considered that the round manhole cover same diameter, when the hole is rolled up, it will be slightly wider than the hole in the bottom and the lid will not fall into the well.

And if you use the square manhole cover, because the diagonal is significantly longer than each of the edges, it’s easy to fall into the well along the diagonal direction of the well and cause safety risks.

Nyob rau hauv lub countryside thiab cable Wells, square feem ntau yog siv, uas tuaj yeem tiv thaiv kev nkag mus ntawm cov kua dej zoo li nag.
