1.灰鑄鐵具有較好的減震性,用灰鑄鐵制作機(jī)電設(shè)備上的底座或機(jī)架等零件,比如測功器鑄鐵平臺。能夠有效的吸收機(jī)器振動的能量,從而起到阻尼的作用,這也是灰鑄鐵最為重要的性能。
2.灰鑄鐵具有良好的導(dǎo)熱性能,用灰鑄鐵制作內(nèi)燃機(jī)上的汽缸體,汽缸蓋時,可迅速到處大量的熱量,這中良好的導(dǎo)熱性低于在高溫下工作的機(jī)電設(shè)備是很重要的。
3.灰鑄鐵具有良好的潤滑性能,用灰鑄鐵制作機(jī)電設(shè)備上經(jīng)受滑動摩擦的零件時,具有良好的減磨性能。在有水分存在的情況下,石墨是很好的潤滑劑,而一旦石墨從基體上脫落時所留下的空間又便于存住潤滑油,這也是灰鑄鐵作為良好耐磨材料的重要條件之一。
4.灰鑄鐵在同一應(yīng)力下反復(fù)加載時,具有加載次數(shù)增加,應(yīng)變曲線彎曲程度明顯減小,卸載后殘留塑性變形也減少的特性。鑄鐵平臺就是利用這種特性,可通過過精加工前一定次數(shù)的預(yù)加載,獲得高的鑄件穩(wěn)定性。
5.灰鑄鐵具有良好的鑄造和切削加工性,其熔煉比較方便,與鑄鋼相比,融化溫度較低,熔煉設(shè)備和熔煉工藝都都比較簡單,在鑄造性能方面,灰鑄鐵液的流動性良好,鑄件不易開裂。
5 basis for cast iron plate casting with
gray iron
1. Gray cast iron has good shock
absorption, and uses gray cast iron to make parts such as base or frame on
electromechanical equipment, such as dynamometer cast iron platform. It can
effectively absorb the energy of the vibration of the machine and thus play the
role of damping, which is also the most important performance of gray cast
iron.
2. Gray cast iron has good thermal
conductivity. The cylinder block on the internal combustion engine is made of
gray cast iron. When the cylinder head is used, a large amount of heat can be
quickly everywhere. It is very important that the good thermal conductivity is
lower than that of the electromechanical equipment working at high temperature.
.
3. Gray cast iron has good lubricity. When
using gray cast iron to make parts subjected to sliding friction on
electromechanical equipment, it has good anti-wear performance. In the presence
of moisture, graphite is a good lubricant, and once the graphite is detached
from the substrate, the space left is convenient for storing the lubricating
oil, which is one of the important conditions for gray cast iron as a good
wear-resistant material. .
4. When the gray cast iron is repeatedly
loaded under the same stress, the loading times are increased, the strain curve
is obviously reduced, and the residual plastic deformation is also reduced
after unloading. The cast iron platform utilizes this feature to achieve high
casting stability by preloading a certain number of times before finishing.
5. Gray cast iron has good casting and
cutting processability, and its smelting is convenient. Compared with cast
steel, the melting temperature is lower, the smelting equipment and the
smelting process are relatively simple, and the flowability of gray cast iron
liquid in terms of casting performance Good, the casting is not easy to crack.
