The specific operation of nodular casting is: placing the alloy block on the bottom of the bag and covering it with iron filings (thin steel plate can also be used). When the molten iron is full, stir the molten iron with a stir (speed up the reaction) and immediately add straw ash to the molten iron (reduce heat radiation and oxidation). When the nodularization reaction is over, take out some molten iron with a sampling spoon, pour the test piece into a shape, water-cool it after solidification, break it, and check the section to determine the degree of nodularization. When the requirements are met, the molten iron is poured into a ladle for casting. 、清整处理后得到有预定形状 、尺寸和性能的铸件（零件或毛坯）的工艺过程。 The process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and solidifying and finishing , a casting (part or blank) with a predetermined shape , size and performance is obtained . Basic technology of modern machinery manufacturing industry. The cost of the blank produced by casting is low, and it can show its economy more for the parts with complex shapes, especially with complicated inner cavity. At the same time, it has a wide adaptability and good comprehensive mechanical properties. However, there are many materials (such as metal, wood, fuel, modeling materials, etc.) and equipment (such as metallurgical furnaces, sand mixers, modeling machines, core making machines, falling sand machines, shot blasting machines, etc.) required for casting production, It will pollute the environment with dust, harmful gases and noise.
The casting process can be divided into three basic parts, namely the preparation of the cast metal, the preparation of the mold and the processing of the casting. Casting metal refers to the metal material used for casting in casting production. It is an alloy composed of one metal element as the main component and the addition of other metal or non-metallic elements. Cast steel and non-ferrous alloys.
Metal smelting is not just a simple melting, but also a smelting process, so that the metal poured into the mold, in terms of temperature, chemical composition and purity, meets the expected requirements. For this reason, during the smelting process, various inspections and tests are conducted for the purpose of quality control, and the liquid metal can be allowed to be poured after it has reached various prescribed targets. Sometimes, in order to meet higher requirements, the metal liquid must be processed outside the furnace after it is released, such as desulfurization, vacuum degassing, refining outside the furnace, inoculation or deterioration treatment. Commonly used equipment for smelting metal are cupola furnace, electric arc furnace, induction furnace, resistance furnace, reflex furnace, etc.
