Casting
Key words:
Casting is a kind of metal thermal processing technology that human beings have mastered relatively early, and it has a history of about 6000 years. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the technology has reached a very high level. Casting is the method of casting liquid metal into the casting cavity suitable for the shape of the part, and then cooling and solidifying to obtain the part or blank. The cast material is usually a metal that is originally solid but heated to liquid (e. g., copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal, or even ceramic. The methods used will vary according to different requirements.
The main production equipment is 3 sets of 1T medium frequency hearth furnace, 1 automatic sand treatment line, 2 sets of full-automatic vertical molding machine, 2 sets of shot blasting machine, 2 sets of shaping machine, 12 sets of flat mouth machine, 17 sets of tapping machine, 1 set of 20T electric annealing kiln, etc.

Precautions for installation of grooved pipe fittings
Select a suitable sealing ring when ordering the groove parts. Different media in the pipeline require sealing rings of different materials. At present, there are eight sealing rings of different materials on the market to apply different media.
What is the casting characteristics of Shanxi Masteel pipe fittings?
The casting performance of Marsteel is good. Its fluidity (measured by the length of the spiral specimen) is better than that of ductile iron and gray iron of comparable strength, and it is easy to pour into thin small castings with clear contours.
Classification, characteristics and equipment used in forging
Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components.
Development Trend and Prospect of Foundry Industry
The foundry industry is facing great opportunities and challenges in the future development. By actively adapting to market demand, promoting technological innovation, strengthening environmental protection and optimizing management, the foundry industry is expected to achieve sustained and stable development and make greater contributions to industrial development and economic growth.
Present Situation and Future Trend of Foundry Industry
As an important part of the manufacturing industry, the foundry industry is of great significance to promote the development of the national economy.
Precautions for the production of ductile iron castings
Ductile iron is a high-strength cast iron material, its comprehensive performance is close to steel. Ductile iron is spheroidal graphite obtained by spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel. It is based on its excellent performance, has been successfully used for casting some complex force, strength, toughness, wear resistance requirements of the higher parts. Ductile iron castings have developed into a cast iron material that is second only to gray iron and is widely used. The so-called "iron on behalf of steel", mainly refers to the ductile iron.
