Hello, the main classification of cast iron can be divided into four main categories:

1. Gray cast iron;

2. White cast iron;

3. Malleable cast iron;

4. Ductile iron.

Different types of cast iron have different carbon content, process and structure, and will have different applications and values.

Types, uses and characteristics of cast iron.

Cast iron can be divided into the following according to the fracture color

Grey cast iron. The carbon content is high (, the carbon mainly exists in the form of flake graphite, and the fracture is gray, referred to as gray iron. The melting point is low (1145 1250), the shrinkage is small when solidified, the compressive strength and hardness are close to carbon steel, and the shock absorption is good.

It has certain mechanical properties and good machinability, and is widely used in industry to manufacture machine tool beds, cylinders, boxes and other structural parts.

White cast iron. The content of carbon and silicon is low, and the carbon mainly exists in the form of cementite, and the fracture is silvery-white. During solidification, the shrinkage is large, and it is easy to produce shrinkage holes and cracks.

It has high hardness and brittleness, and cannot withstand impact loads. It is mostly used as a blank of malleable cast iron and to make wear-resistant parts.

Hemp cast iron is a kind of cast iron between white cast iron and gray cast iron, and its fracture is gray and white pockmarked shape, the performance is not good, and it is rarely used.

Cast iron can be divided into the following according to its chemical composition

It refers to cast iron that does not contain any alloying elements, such as gray cast iron, malleable cast iron, ductile iron, etc.

Alloy cast iron. Ordinary cast iron is obtained by adding an appropriate amount of alloying elements (such as silicon, manganese, phosphorus, nickel, chromium, molybdenum, copper, aluminum, boron, vanadium, tin, etc.). Alloying elements change the matrix structure of cast iron, so that it has corresponding characteristics such as heat resistance, wear resistance, corrosion resistance, low temperature resistance or non-magnetism.

It is used in the manufacture of parts and components for mining, chemical machinery and instruments, meters, etc.

Cast iron can be divided into the following according to the production method and tissue properties

Plain gray cast iron. Most or all of the carbon in this cast iron exists in the form of flake graphite in a free state, and its fracture is dark gray, with certain mechanical properties and good cutting properties, which are widely used in industry.

Cast iron is incubated. This is based on gray cast iron, which is made by "metamorphic treatment", also known as metamorphic cast iron. Its strength, plasticity and toughness are much better than that of ordinary gray cast iron, and the structure is also more uniform.

It is mainly used to manufacture large castings with high mechanical property requirements and large cross-sectional size changes.

Malleable iron. Obtained by annealing of white cast iron, graphite is distributed in a flocculent form, referred to as tough iron. Its microstructure is uniform, wear-resistant, and has good plasticity and toughness. It is used to manufacture parts with complex shapes and strong dynamic loads.

Nodular cast iron. The gray cast iron molten iron is obtained after spheroidization, and the precipitated graphite is spherical, referred to as ductile iron. It has higher strength, better toughness and plasticity than ordinary gray cast iron. It is used in the manufacture of internal combustion engines, auto parts and agricultural machinery.

Special properties cast iron. This is a kind of cast iron with certain characteristics, which can be divided into wear-resistant cast iron, heat-resistant cast iron, corrosion-resistant cast iron, etc., according to different uses. Most of them belong to alloy cast iron, which is widely used in machinery manufacturing.

According to the existence of different forms of carbon, cast iron is divided into three categories: white cast iron, carbon mainly exists in the form of cementite, this kind of cast iron is hard, brittle, and rarely used directly; Gray cast iron, carbon mainly exists in the form of graphite, this kind of cast iron has different properties and uses due to different graphite shapes; Hemp cast iron, part of the carbon exists in the form of cementite and the other part exists in the form of graphite, this kind of cast iron is also hard and brittle, and is rarely used directly.

Gray cast iron is commonly used in production, which is divided into four categories according to the different shapes of graphite: gray cast iron, graphite is flaked, poor mechanical properties, castability, shock absorption, friction reduction, gap sensitivity, and machinability are better than steel; Malleable cast iron, graphite is flocculent, and the mechanical properties are slightly higher than that of gray cast iron; Ductile iron, graphite is spherical, and its mechanical properties are equivalent to quenched and tempered steel; Graphite cast iron, graphite is worm-like, and the mechanical properties are slightly lower than that of ductile iron.

Casting [ zhù zào ].

Vocabulary book. Basic Definition Detailed Definition.

zhù zào ]

The metal is melted and poured into the mould to form a predetermined object. This includes the fabrication of molds, melting of metal, casting and cleaning. The casting mold made of sand is widely used, so it is also known as turning sand.

Molding sand is a material used for modeling in casting. Molding sand is generally made of casting raw sand, molding sand binders and auxiliary additives and other modeling materials mixed in a certain proportion. Molding sand can be divided into clay sand, sodium silicate sand, cement sand, resin sand, etc. according to the different binders used.

Clay sand, sodium silicate sand and resin sand are the most used.

The role of molding sand in casting production is extremely important, and the casting waste caused by the poor quality of molding sand accounts for about 30 50% of the total casting waste. The usual requirements for molding sand are: It has high strength and thermal stability to withstand various external forces and high temperatures.

Good flow sock blind motility, that is, the ability of the sand to move between sand particles under the action of external force or its own gravity. A certain plasticity, that is, the ability of the molding sand to be deformed under the action of external force, and when the external force is removed, it can maintain the shape given. Good air permeability, that is, the ability of the pores of dry sand to transmit gas.

High dispersibility, also known as sand extraction, is the performance of whether the molding sand is easy to destroy after the casting is solidified, and whether it is easy to remove from the casting.
