The demand for iron castings in various spheres of life is undeniable. From decorative elements of architecture to gutters and sewer manholes - its ability to withstand environmental influences allows the use of products from this material almost everywhere. The weight of such products is large enough, which creates some inconvenience, but they are very successfully compensated by durability and wear resistance. However, this statement is true only for the products of reputable manufacturers, whose equipment and technologies allow them to produce material that meets the requirements of GOST. Since the lack of such compliance can lead to unpredictable behavior of iron casting products during operation, our company sells only guaranteed, tested, meeting the requirements and having all the necessary documentation for iron casting. This approach allows us to guarantee customers the absence of marriage in any batch of goods.
The methods of iron casting at our partner enterprises are constantly being improved, which, combined with careful quality control at all stages of production, gives confidence in an excellent result. In order not to be unfounded, we will briefly talk about how it is produced and what factors affect its quality.
Actually, first of all, quality is determined by the correct choice of material that will be loaded into the melting furnace, the so-called mixture. To get iron castings, the mixture is formed in the form of blast furnace ingots and scrap with the addition of steel waste and fluxes. The selection is carried out in accordance with the required chemical composition of the casting, which, in turn, is determined by its purpose. The selection should also take into account the likely changes in the composition with increasing temperature or contact with the fuel during the melting process. For example, a well-calculated technology takes into account changes in the amount of carbon, oxidation of manganese and silicon contained in the alloy, and an increase in sulfur content. The calculation of the composition of the charge is adjusted for such changes.
The quality of the resulting castings is tested in tension and bending. Test results according to GOST are reflected in the labeling of iron castings. At the modern level, thanks to the developed technologies, it has great potential. Despite this, when designing a product from this material, designers are trying to combine the functionality of the product, its appearance with the most lightweight configuration. This is done to simplify the molding, which, ultimately, leads to the convenience and quality of subsequent operations - cutting and cleaning. This is especially true for those types of cast iron, which due to their properties are more difficult to process due to their own tendency to crack. Another reason for simplifying molding is the reduction in the cost of the product. The manufacture of geometrically complex castings is inevitably associated with an increase in the cost of work, so in many cases it is more advisable to resort to manufacturing the product in parts with subsequent welding.
Iron casting is widely used in industry, and both large-size castings used in the hydraulic turbine structure are used, as well as small parts for electric networks, pipes and elements of pipelines, hatches. In addition, it is actively used as a way to create decorative elements in interior and landscape design.
