Cast Iron Technology

With the complication of metal processing technologies, new alloys for structures arise, and many directions in the metallurgical sphere cease to be relevant. However, materials that have stood the test of time and remained indispensable due to their qualities are still actively used in different industries.

Casting of cast iron is still one of the main directions in the work of most metallurgical companies. The reason lies in the fact that products from this material are characterized by high demand. Such products are characterized by a long service life, as well as strength.

Cast Iron Technology

The production process has not changed much over time. Casting of cast iron is the production of cast iron castings according to certain drawings, in which their parameters are set.

The process of implementation depends on the technology that is applied to a particular enterprise. At the same time, on the whole, it assumes that the alloy in liquid form is supplied in special forms. After cooling of cast iron and its transition to a solid state, it can be cut and removed from the mold, and then subjected to further operations. In the production of cast iron castings it is assumed that further machining of the products will be carried out.

Companies that specialize in certain methods of casting cast iron produce an extensive range of spare parts for various industrial sectors. The areas of use and the parameters of cast iron castings depend on the brand of this material.

Production

In the industrial sphere, namely in the production of machines and machines, water disposal and supply systems, the demand for parts made of cast iron, called "gray", is high. The reason for this lies in the fact that such material is durable and wear-resistant. These properties are provided by the fact that graphite is added to the alloy.

Various industrial companies apply for such a service as casting products from pig iron to order. Despite the fact that there are differences in the requirements for the technological process, which are explained by the specific features of the activities of individual customers, there is a general requirement. It consists in the fact that the manufacture of cast iron castings must comply with the characteristics of the parts, which are indicated in the drawings and documents.

Methods

Casting of cast iron in cold-hardening mixtures is one of the modern technologies. This solution assumes that the molds are made from a mixture that incorporates binding elements, for example, resins. The advantage of a mold made from such a mixture is an increased tightness. Due to this, the possibility that in the production process the integrity of the product structure will be broken is excluded.

Popularity also uses casting using sand molds. This technology uses sand, which was compacted. This method is suitable for the serial production of large parts, for example, blades for turbines or large parts of other mechanisms.

Currently, cast iron castings are undergoing active development. In the technological sphere new production methods are successfully introduced.
