With the complexity of metalworking technologies, new alloys for structures appear, and many areas in the metallurgical sphere cease to be relevant. However, materials that have stood the test of time and remained indispensable because of their qualities are still actively used in various industries.
Iron casting is now one of the main directions in the work of most metallurgical companies. The reason is that products from this material are in high demand. Such products are characterized by a long service life, as well as durability.
Cast Iron Technology
The production process has not changed much over time. Cast iron casting is the production of cast iron castings according to certain drawings, in which their parameters are set.
The execution process is dependent on the technology that is applied at a particular enterprise. Moreover, in general, it assumes that the alloy in liquid form is supplied in special forms. After cooling the 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 iron castings, it is assumed that further machining of the products will be performed.
Companies that specialize in specific casting techniques produce an extensive range of spare parts for various industrial sectors. Areas of use and performance of cast iron castings depend on the brand of this material.
Production
In the industrial sphere, namely in the production of machines and machine tools, water disposal and water supply complexes, there is a high demand for parts that are made of cast iron, called “gray”. The reason for this lies in the fact that such a material is durable and wear-resistant. These properties are ensured by the fact that graphite is added to the alloy.
Various industrial companies apply for such a service as casting iron products to order. Despite the fact that there are differences in the requirements for the technological process, which are explained by the characteristics of the activities of individual customers, there is a general requirement. It consists in the fact that the manufacture of iron casting must comply with the characteristics of the part, which are indicated in the drawings and documents.
Methods
Casting of iron into cold-hardening mixtures is one of the modern technologies. This solution assumes that the molds are made from a mixture that includes binders, such as resins. An advantage of a mold made from such a mixture is increased tightness. Due to this, the possibility is excluded that during production the integrity of the product structure will be violated.
Sand casting is also popular. This technology uses sand that has been compacted. This method is suitable for serial production of large parts, for example, turbine blades or large parts of other mechanisms.
Currently, iron casting is undergoing active development. New production techniques have been successfully introduced into the technological field.
