Isfahan cast iron casting

Isfahan cast iron casting

Cast iron is an alloy of iron containing 2 to 4% carbon, with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. This material is made by reducing iron ore in the furnace. Cast iron is produced by smelting iron and carbon alloys with a carbon content of more than 2%. After melting, the metal is poured into the mold. The primary difference in production between wrought iron and cast iron is that cast iron does not work with hammers and tools. There are also differences in composition – cast iron contains 2-4% carbon and other alloys and 1-3% silicon, which improves the casting performance of molten metal. Small amounts of manganese and some impurities such as sulfur and phosphorus may also be present. The difference between wrought iron and cast iron can also be found in the details of its chemical structure and physical properties. Although both steel and cast iron contain traces of carbon and look similar, there are significant differences between the two metals. Steel contains less than 2% carbon, which makes the final product solid in a microcrystalline structure. The higher carbon content of cast iron means that it solidifies as a heterogeneous alloy and therefore has more than one microcrystalline structure in the material. It is a combination of high carbon content and silicon that makes cast iron very good casting. In Isfahan cast iron casting, different types of cast iron are produced using different heat treatment and processing techniques, including gray iron, white iron, flexible iron, malleable iron and compressed graphite iron. Apadana smelting industry provider Steel casting services, foundry modeling, has a cast iron casting agency in Isfahan.

Production of casting parts in Isfahan

Casting parts production processes in Isfahan may be different from other factories, and follows the following steps:
Project and design:
The starting point of the casting method is the order received from the customer.
First it is necessary to study the feeding system and filling of the manufactured parts and to make the necessary patterns and main boxes.
Melting and casting:
Depending on the type of alloy to be produced (wear-resistant steels, impact-resistant steels, stainless steels, heat-resistant steels, carbon steels), steel is melted at temperatures between 1450 ° C and 1650 ° C.
After the steel has solidified, a solid piece (cast) is obtained. This solid part (in the form of casting) must be sent to the next processes to reach the final design and shape desired by the customer.
Molding:
Casting molding is produced by separating casting sand (containing sand) from the casting product, an operation performed by the system.
Measurements of mechanical properties obtained in steel such as tensile strength, yield strength, impact resistance and hardness are performed in various laboratory test equipment of mechanical analysis and metallography.
Quality control and inspection:
All casting processes are subject to special quality control methods (dimensional and visual inspection, hardness, control of magnetic particles, X-rays, etc.), to ensure that defects are found and each step of the process is not transferred to the following processes Be.
Machining:
The whole production process of steel casting is completed by casting machining to obtain the dimensions required by the customer.
Metal casting is a process that is fully compatible with mass production needs. Heavy and very large metal objects may be dumped that would otherwise be difficult or economically impossible to produce.
Some engineering properties are obtained in casting metals more favorably.
for example:
More uniform characteristics from a point of view; For example, cast metals show similar properties regardless of the direction of the test piece relative to the main casting. Strength and lightness in light metal alloys, which can only be produced by casting. Good bearing quality in Metal casting is obtained.
The process of casting metals has more advantages. Of course, it is also true that there may be situations where the casting process must be replaced by other production methods, while other processes may be more efficient. The traditional method of obtaining casting geometry is by sending prototype drawings to the casting. This is usually done when requesting the pricing process. However, most customers and foundries are exchanging geometry and partly through computer-aided design files.
The physical pattern is the casting used to make the mold. Molding involves all the operations required to prepare the mold to receive the molten metal. Mold making is usually the placing of a mold around a pattern that is held in place by a retaining frame, pulls the pattern out of the mold cavity, places the cores in the mold cavity, and closes the mold.
The preparation of molten metal for casting is called melting. Melting is usually determined in a specific area of ​​the casting and the molten metal is poured into the area and filled there and transferred to the molds.
Cleaning is all the operations necessary to remove excess metal from the casting. The casting is removed from the mold and transferred to the cleaning section. Casting may be enhanced by welding or other methods. Casting inspection is performed for defects and general quality.
