球墨铸铁井盖的制作方法普及!

来源:http://www.kpp647.com添加时间:2019-06-25 16:21:54

球墨铸铁井盖是球墨铸铁产品的一种,球墨铸铁通过球化和孕育处理得到球状石墨,有效地提高了铸铁的机械性能,特别是提高了塑性和韧性,从而得到比碳钢还高的强度。下面小编就给大家讲解一下这种井盖的制作方法!

Ductile iron well cover is a kind of nodular cast iron products. The nodular graphite is obtained by nodularization and inoculation treatment of nodular cast iron, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than that of carbon steel. The following edition will explain to you how to make this kind of well cover!

(一)严格要求化学成分,对原铁液要求的碳硅含量比灰铸铁高,降低球墨铸铁中锰,磷,硫的含量

(1) Strict chemical composition is required. The content of carbon and silicon required for molten iron is higher than that of gray cast iron. The content of manganese, phosphorus and sulfur in nodular cast iron is reduced.

(二)铁液出炉温度比灰铸铁更高,以补偿球化,孕育处理时铁液温度的损失

(2) The tapping temperature of molten iron is higher than that of gray cast iron in order to compensate for the loss of molten iron temperature during spheroidization and inoculation treatment.

(三)进行球化处理,即往铁液中添加球化剂

(3) Spheroidizing treatment, i。e。 adding spheroidizing agent to molten iron

(四)加入孕育剂进行孕育处理

(4) Adding inoculants for inoculation treatment

(五)球墨铸铁流动性较差,收缩较大,因此需要较高的浇注温度及较大的浇注系统尺寸,合理应用冒口,冷铁,采用顺序凝固原则

(5) Ductile iron has poor fluidity and large shrinkage, so higher pouring temperature and larger size of pouring system are needed. Risers and chills should be reasonably applied and sequential solidification principle should be adopted.

(六)进行热处理

(6) Heat treatment
