Casting iron, also known as cast iron, is a ferrous alloy containing more than 2.4% carbon, more than 1% silicon and a number of metals. It has high hardness, good wear resistance and good elasticity. It is mainly used to manufacture some components and parts which are large and complex, and it is also an important engineering material which can not be replaced by other materials. It has a wide range of applications in many fields, and its use in the processing of machine tools is particularly important.
Casting iron used in the processing of machine tools, the main brand number is ZL101 and ZL102, its mechanical properties are as follows:
ZL101 has the highest abrasion resistance, its metallographic structure is dense pearlite matrix structure, containing more M alloying agent, combined with higher carbon content, making it suitable for all kinds of high hardness and wear-resistant parts, such as machining racks, etc.
The mechanical properties of ZL102 are also very good. Its metallographic structure is mostly hypereutectic and pro eutectic structure. Combined with relatively lower carbon content, the combination effect of suitable elements has the characteristics of good mechanical properties, compression resistance and abrasion resistance, which makes it suitable for some components and parts with high precision machining requirements, and at the same time improve the machining performance.
Casting iron is commonly used for the production of machine tool guide rails. Compared with other materials, it has the advantages of high hardness and wear resistance, good elasticity and toughness, low fracture and good cutting performance. In addition, its good performance also makes it suitable for the production of some functional parts, such as coordinate measurement tools, turntable bearings and other components.
At present, the application of casting iron in the processing of machine tools is very extensive. Whether it is the guideways of the slide and slide table of the machine tool or the stabilizer rack, the guide shaft and other main parts are basically made of cast iron. Its unique properties make it the best choice for the production of machine tool parts.
In summary, casting iron is an important engineering material with various advantages of high hardness, good wear resistance, good elasticity and toughness, low fracture and good cutting performance, so it is widely used in various machine tool processing applications. The two main types of ZL101 and ZL102 are particularly suitable for use in the production of machine tool guide rails, stabilizer racks and other parts. Therefore, it is an important tool material that people rely on in the development of machine tools.
