Bomba la chuma la ductile
-
Nodular cast iron steel pipes are essentially ductile iron pipes, which have the essence of iron and the properties of steel, hence their name. Graphite in ductile iron pipes exists in a spherical form, with a general size of 6-7 grades. Kwa upande wa ubora, kiwango cha spheroidization ya bomba la chuma la kutupwa inahitajika kudhibitiwa katika viwango vya 1-3, na kiwango cha spheroidization cha ≥ 80%. Therefore, the mechanical properties of the material itself have been improved, possessing the essence of iron and the properties of steel. Baada ya kushinikiza, muundo wa bomba la chuma ductile ni feri na kiwango kidogo cha lulu, ambayo ina mali nzuri ya mitambo, kwa hivyo pia huitwa bomba la chuma la chuma.
