鑄鐵平臺鑄件缺陷種類繁多，作為分類群進行分類，大都以缺陷外觀特征作為分類依據(jù)。各國對鑄件的分類和定義不同。分析鑄鐵平臺鑄件的形貌、特點、產(chǎn)生的原因及形成過程，目的是防止、減少、消除鑄件缺陷，消除或減少鑄件缺陷是質(zhì)量控制的重要組成部分。
鑄鐵平臺鑄件質(zhì)量主要包括外觀質(zhì)量、內(nèi)在質(zhì)量和使用質(zhì)量。
1、外觀質(zhì)量指鑄鐵平臺鑄件表面粗糙度、表面缺陷、尺寸偏差、形狀偏差、質(zhì)量偏差。
2、內(nèi)在質(zhì)量主要指鑄鐵平臺鑄件的化學(xué)成分、物理性能、力學(xué)性能、金相組織以及存在于鑄件內(nèi)部的孔洞、裂紋、夾雜、偏析等情況。
3、使用質(zhì)量指鑄鐵平臺鑄件在不同條件下的工作耐久能力，包括耐磨、耐腐蝕、耐激冷激熱、疲勞、吸震等性能以及切削性、可焊性等工藝性能。
What are the defects of cast iron platform
castings?
Cast iron platform castings have a wide
variety of defects, and they are classified as taxonomic groups. Most of them
are based on the defect appearance characteristics. Countries have different
classifications and definitions of castings. The analysis of the shape,
characteristics, causes and formation process of cast iron platform castings is
to prevent, reduce and eliminate casting defects, and to eliminate or reduce
casting defects is an important part of quality control.
The quality of cast iron platform castings
mainly includes appearance quality, intrinsic quality and quality of use.
1. Appearance quality refers to the surface
roughness, surface defects, dimensional deviation, shape deviation and quality
deviation of cast iron platform castings.
2. The intrinsic quality mainly refers to
the chemical composition, physical properties, mechanical properties,
metallographic structure of the cast iron platform castings, as well as the
holes, cracks, inclusions, segregation and the like existing in the casting.
3, the use of quality refers to the working
durability of cast iron platform castings under different conditions, including
wear resistance, corrosion resistance, chilling heat, fatigue, shock absorption
and other properties as well as machinability, weldability and other process
performance.
