鑄鐵平板生產(chǎn)過(guò)程中，有很多的步驟及操作流程，其中硬度和質(zhì)量也是很容易出現(xiàn)問(wèn)題的，一起來(lái)了解一下生產(chǎn)鑄鐵平板時(shí)導(dǎo)致硬度不夠，硬度過(guò)強(qiáng)的因素：
鑄鐵平板鑄造硬度不夠的原因：
1.鑄鐵平板是由于鑄鐵平板底料廢剛比例偏高。提高鑄鐵平板中生鐵或者回爐料的比例改善平板的硬度。
2.鑄鐵平板是由于平板碳含量偏低。提高平板中碳的含量會(huì)使鑄鐵平板硬度加強(qiáng)。
鑄鐵平板硬度過(guò)強(qiáng)的原因：
1.鑄鐵平板是由于平板孕育劑的量偏少，使得鑄鐵平板薄壁處得不到良好孕育而偏硬甚至白口。提高平板中孕育劑的含量會(huì)使鑄鐵平板硬度降低。
2.鑄鐵平板是由于平板合金元素偏高了，比如錳、鉻，強(qiáng)度符合工藝還有較大余量的情況下可以適當(dāng)降低合金元素含量使鑄鐵平板硬度降低。

In the production of cast iron plate, there
are many steps and operation procedures, among which hardness and quality are
easy to be problematic. Let's understand the factors that lead to insufficient
hardness and excessive hardness in the production of cast iron plate.
Reasons for insufficient hardness of cast
iron plate casting:
1. Cast iron plate is due to the high ratio
of waste rigidity of the base material of cast iron plate. Increase the
proportion of pig iron or return charge in cast iron plate to improve the
hardness of the plate.
2. Cast iron plate is due to the low carbon
content of the plate. Increasing the carbon content in the cast iron plate will
enhance the hardness of the cast iron plate.
Reasons for Excessive Hardness of Cast Iron
Plate:
1. Cast iron plate is hard or even white
because of the low amount of inoculant in the plate, which makes the thin wall
of the cast iron plate not well inoculated. Increasing the content of inoculant
in the slab will reduce the hardness of the cast iron slab.
2. Cast iron plate is due to the high alloy
elements, such as manganese and chromium, which can reduce the hardness of cast
iron plate if the strength is in line with the process and there is a large
margin.
Has many years of technical experience in
the production of cast iron plate, over the years the reputation of users and
friends to witness our quality, cast iron plate family, professional
households!
