The cast iron casting process involves the process design of iron casting itself, the design of the gating system, the design of the feeding system, the design of the exhaust port, the design of the chill system, and the special design. Cast iron casting process, etc. Next, let's take a look at the design of the cast iron casting process.
Here is the content list:
The process design of the part itself of the Cast iron casting process
Cast iron casting process casting system
Feeding system of Cast iron casting process
The process design of the Cast iron casting process part itself involves the machining allowance of the Cast iron casting process part, the selection of the pouring position, the selection of the parting surface, the selection of the Cast iron casting process parameters, the dimensional tolerance, the shrinkage rate, the draft angle, and the correction Design of negative number point of quantity, type, etc.
The casting system of the Cast iron casting process is a channel that guides the molten metal into the mold cavity. Whether the casting system of the Cast iron casting process is designed reasonably or not, it has a great impact on the quality of iron casting and is likely to cause various types of casting defects. For example insufficient pouring, cold barrier, sand-washing, slag inclusion, inclusions, sand inclusions, and other casting defects. The design of the gating system of Cast iron casting process includes the selection of the type of the gating system, the selection of the position of the inner gate, and the determination of the cross-sectional dimensions of each component of the gating system of the Cast iron casting process. In addition, the choice of Cast iron casting process gating system is also very important, so how can we choose the correct Cast iron casting process gating system?
Nowadays, to facilitate production and ensure the quality of iron casting, the inner runner of the Cast iron casting process casting system is generally set on the parting surface of the iron casting mold. According to the pouring position of the iron casting blank and the selection of the parting surface, the inner runner opened on the parting surface of the iron casting mold belongs to the "medium casting" gating system. Liquid metal will inevitably contain a certain amount of "slag" during the casting process. To improve the slag retaining ability of the casting system of the cast iron casting process, a "closed" casting system should be adopted. In the cast iron casting process, the design of the cast iron casting process has a great influence on the quality of the cast product, but the choice of the casting system selection method of the cast iron casting process cannot be ignored.
The design of the feed system of the cast iron casting process is an engineering technology of rational design of risers and subsidies to compensate for the shrinkage of liquids and solids produced in the solidification process of iron casting to obtain a good iron casting. The vent hole of the cast iron casting process feed system is used to discharge the gas in the cavity, improve the filling capacity of the molten metal, remove the scum of the supercooled molten metal and the first filling of the cavity, and can also be used to observe whether the cavity is full Logo.
