How to Choose The Production Process of Steel Castings?

Like the general large-scale steel casting products, in addition to its large size and large outline, the wall thickness is also relatively large, so the technological measures taken by the steel casting manufacturers are very important.

(1) Cold iron is generally divided into internal cold iron and external cold iron, for thick parts such as spindle box and workbench, we have designed a welded internal cold iron frame inside, and the outside is to place graphite cold iron.

(2) The insulation riser is mainly for the thick part of the casting on the box, and the insulation riser of different specifications can play a very good role in replenishing and shrinking, and can also reduce the amount of metal liquid.

(3) For tall and large castings, steel casting manufacturers have designed a total of two sets of pouring systems, the upper one, about one-third of the total height from the upper box, a set of lower and middle areas, the metal liquid will be charged into the pouring system in the lower middle area first, and the pouring system above will be backward, at the same time, the temperature of the metal liquid above is higher than that poured first, so that the pouring system will have a good shrinkage effect on the castings.

(4) Before the start of casting, steel casting manufacturers generally adopt computer simulation technology to simulate various preset process schemes for large castings, which can avoid the risk of large castings not being tested and then produced, and can improve the success rate of large castings. We will carry out process simulation on all castings to ensure the quality of castings.

As a traditional metal forming industry, with the continuous development of science and technology, steel casting is also constantly integrating materials and technologies from other industries to achieve its own transformation and growth. In the near future, the composition and properties of raw materials, including scrap, refurnace and pig iron, and the metal liquid formed by a series of reactions that occur during the melting process, will be more clearly understood by more people after filling, cooling, solidification, cooling and other links. In terms of making patterns, resin and steel and other materials have also replaced traditional wood, which are the future development trend and direction of castings, and at the same time will have a very important impact on steel casting manufacturers.
