demand for iron castings in various spheres of life is undeniable.From the architecture to the decorative elements of drainage grates and manholes - properties withstand the environment allow the use of products from this material almost everywhere.
weight of such products is large enough, which creates some inconvenience, but they are very well compensated for durability and wear resistance.However, this statement is valid only for the production of solid manufacturers, equipment and technologies that allow them to produce material that meets the requirements of GOST.Since the absence of such compliance can result in unpredictable behavior of cast iron products in the course of operation, our company implements only guaranteed proven that meets the requirements and has all the necessary documentation iron castings.This approach allows us to guarantee our customers the absence of a marriage in any consignment.
Methods cast iron enterprises who are our partners, constantly improved, which, combined with strict quality control at all stages of production provides confidence in a magnificent result.Not to be unfounded, briefly describe how it is produced and what factors affect its quality.
Actually, first of all determined by the quality of the best one material to be loaded into the melting furnace, the so-called batch.To get the cast iron, the charge is formed in the form of ingots and scrap domain with the addition of steel scrap and fluxes.Selection is carried out in accordance with the desired chemical composition of the casting, which in turn is determined by its purpose.Selection should also take into account possible changes in the composition at higher temperatures or in contact with the fuel in the melting process.For example, well-designed technology allows for changes in the amount of carbon oxidation of manganese and silicon contained in the alloy, the increase in sulfur content.The calculation of the charge composition is adjusted for such changes.
quality of the resulting castings are tested for tensile and flexural strength.The test results are recorded in accordance with GOST marking cast iron.At the present level, thanks to the developed technology, it has great potential.Despite this, when designing the product from this material, designers try to combine the functionality of the product, its appearance with light-weight configuration possible.This is done for ease of molding, which ultimately leads to the convenience of subsequent operations and quality - stumps and purification.This is especially true of the types of cast iron, which by virtue of its properties difficult to machine due to their own susceptibility to cracking.Another reason to simplify the molding - reduction of the cost of the product.Production of geometrically complex castings invariably associated with an increase in the price of work, so in many cases it is more expedient to resort to the manufacture of the product, followed by parts welding.
Cast iron is widely used in the industry, and are used as large castings used in the structure of water turbines and small parts for electrical networks, pipes and piping components, hatches.In addition, it is widely used as a way to create decorative elements in interior and landscape design.
