Today, we will bring you the main purpose of insulating riser. I hope that through our introduction, you can have a deeper understanding of Zhengzhou Dongsheng Metallurgical New Material Co., Ltd. and other issues,

insulating riser is very good, and has good quality. It is widely used in the production of various types of steel, cast iron and non-ferrous alloy castings. It can effectively prolong the cooling time of molten metal, enhance the feeding effect, increase the yield of casting process, reduce production cost, reduce the weight of riser, save the cost of metal melting and cutting riser, reduce the loss of moulding sand and metal, save energy and labor, reduce the production cost of castings, improve the internal quality of castings and the dense riser of castings, and the main insulating riser.

recommends you read this article: What is the function of

riser? How to place riser? When riser is used for casting, air in mould and impurities in casting metal juice can be discharged. Generally small castings can be set without riser, slightly larger castings can be set on the far side of the gate, especially large ones are set at both ends, riser is set up. In the central part, riser size is mostly determined by calculation method, and large castings are designed by computer aided design. The feeding efficiency of riser can be improved by various technical measures. For example, for medium and small castings, it is possible to add a insulating riser around the riser, what is the function of insulating sleeve or heating sleeve, so as to slow down the solidification of riser and achieve the purpose of reducing riser size; In addition to the insulating or heating jacket, it can also be heated by electric arc or flame at the top of riser to slow down its solidification.
