Iron castings such as Furniture Casting Part for industrial development of China's major industry development is very rapid in recent years, mainly for castings porous structure, the ash in the process of origin are the corresponding technical requirements, castings with the requirements of the production process parameters mainly, hot metal melting temperature of main must control the best temperature is between 1500 ~ 1550 ℃, 1530 ℃, so we can ensure that the molten iron of high purity, thus removing the hereditary of graphite iron cast. According to the general casting wall thickness to determine the automobile castings, for example, according to the shape of the casting wall thickness is different, generally in the range of 1400 ~ 1440 ℃. Iron casting should guarantee in the inoculation process, make the inoculant quickly dissolved in molten iron, and exist in the microcosmic concentration difference, guarantee in the subsequent cooling solidification crystallization...
