Every person in the casting market knows a truth. That is the mechanical residential or commercial properties of stainless-steel spreading are more than that of cast iron, yet its casting efficiency is worse than that of actors iron. Stainless-steel spreading belongs to financial investment or precision casting, with fairly high melting factor. The molten steel is conveniently oxidized, as a result of bad fluidness and also big contraction rate. From an useful perspective, stainless steel casting appropriates for casting of various kinds and alloys.
Advantages as well as negative aspects of the stainless steel spreading process are as listed below:
Initially, due to the poor liquidity of the liquified steel, the wall surface density of the steel spreadings must not be much less than 8 mm, in order to protect against the cold closed as well as misrun. The structure of the putting system makes every effort to be straightforward, and also the sectional measurement is larger than that of cast iron. Adopt completely dry casting or warm casting, and also the casting temperature ought to be appropriately enhanced to 1520-1600. The fluidness can be improved because the spreading temperature is high with huge superheat, thus the fluid stays for a very long time.
Nonetheless, if the pouring temperature is too high, it will certainly create issues such as coarse grains, hot splits, pores and sand burning. For that reason, the spreading temperature level of small, thin-walled as well as intricate spreading ought to go to the melting factor +150; and also of huge, thick-walled casting +100.
We must take these steps to prevent the incident of shrinkage openings and also fractures in stainless-steel spreadings. 1. Making the wall surface thickness attire, and also prevent sharp and also best angle structures, 2. Including Yide Machinery to sand mold and mildew, as well as coke to sand core. 3. Adopting hollow sand core and oil sand core to alter the deformability and leaks in the structure of the sand mold and mildew and also core.
