Definition of casting

Casting
A process in which a metal is smelted into a liquid that meets a certain requirement and poured into a mold, and solidified and cleaned to obtain a casting (part or blank) having a predetermined shape, size, and performance. The basic process of the modern machinery manufacturing industry. The blank produced by casting has low cost, and it can show its economicality for parts with complicated shape, especially with complex inner cavity; at the same time, it has wide adaptability and good comprehensive mechanical properties. However, materials required for casting production (such as metal, wood, fuel, modeling materials, etc.) and equipment (such as metallurgical furnaces, sand mixers, molding machines, core making machines, falling sand machines, shot blasting machines, etc.) are more It can pollute the environment by generating dust, harmful gases and noise.
Casting is a metal thermal processing technology mastered by humans. It has a history of about 6,000 years. In 3200 BC, copper frog castings appeared in Mesopotamia. Between 13th and 10th centuries BC, China has entered the heyday of bronze castings, and its craftsmanship has reached a fairly high level, such as the Shang dynasty’s 875 kilograms of the mother-in-law, Fang Ding, the Warring States’ Zeng Houyi, and the Western Han Dynasty. Translucent mirrors are all representative products of ancient casting. The early casting was greatly influenced by pottery, and most of the castings were tools or utensils for agricultural production, religion, and life, and the artistic color was strong. In 513 BC, China cast the world's first iron castings found in the text - Jin Guozhu Ding (about 270 kg weight). Around the 8th century AD, Europe began to produce cast iron parts. After the industrial revolution of the 18th century, castings entered a new era of service for large industries. In the 20th century, the development speed of casting was very fast. The development of spheroidal graphite cast iron, malleable cast iron, ultra-low carbon stainless steel and aluminum-copper, aluminum-silicon, aluminum-magnesium alloy, titanium-based, nickel-based alloy and other cast metal materials was developed. A new process for the inoculation of cast iron. After the 1950s, there were new technologies such as wet sand high pressure molding, chemical hardening sand molding and core making, negative pressure molding, and other special casting and shot blasting.
There are many kinds of castings. According to the modeling method, it is customarily divided into: 1 ordinary sand casting, including wet sand type, dry sand type and chemical hardening sand type. 2Special casting, according to the modeling material, can be divided into special castings with natural mineral sandstone as the main modeling material (such as investment casting, clay casting, casting workshop shell casting, negative pressure casting, solid casting, ceramic casting). Etc.) and special castings with metal as the main casting material (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.). The casting process usually includes: 1 casting (the liquid metal is used as a container for solid casting). The casting can be divided into sand type, metal type, ceramic type, mud type, graphite type, etc. according to the materials used, and can be divided into times according to the number of times of use. Sex, semi-permanent and permanent, the pros and cons of casting preparation are the main factors affecting the quality of castings; 2 melting and casting of casting metals, cast metal (casting alloy) mainly cast iron, cast steel and cast non-ferrous alloy; 3 castings Handling and inspection, casting treatment includes removal of foreign objects on the core and casting surface, removal of the riser, burrs and burrs, as well as heat treatment, shaping, anti-rust treatment and roughing.
