The pouring of steel castings is not a simple task. Many people think that when casting steel castings, the Ningbo railway steel casting manufacturers only need to design the process, make a good shape, put the mold, etc., and then start pouring.In fact, railway steel casting manufacturers have to calculate the amount of molten steel before pouring, pay attention to controlling the speed during pouring, and determine the pouring position of the casting in actual pouring. The pouring position that Ningbo railway steel casting manufacturers should pay attention to refers to the position of the casting in the mold or whether a certain surface is on the top, bottom, or side of the mold when pouring large castings.
In addition, the railway steel casting manufacturers have to ensure that the large castings are filled, and the thin-walled parts are placed in the lower half or below the inner runner, so as to avoid the defects of large steel castings that cannot be poured or cold-shut. If the Ningbo railway steel casting manufacturers are not sure about these factors, the whole pouring process will be difficult to carry out, and the quality of large castings will be difficult to guarantee.
