In Henan deoxidizer raw materials need to have what characteristics in this regard, Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd. know or understand the relevant situation is analyzed, so that you can learn more about the industry in addition to Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd.

riser has different feeding function, its form, size and opening position are different, so the design of riser takes into account the properties of casting alloy and the characteristics of castings. For alloys with small volume shrinkage during solidification (such as gray cast iron) or alloys without concentrated shrinkage (such as tin bronze), the main function of riser is to discharge gas and collect gas in the mould cavity. For castings requiring control of microstructures, the riser can collect the cooled liquid metal at the front of the liquid flow to avoid supercooled structure on the castings. Fig. 2 is a single cast piston ring with a small size opposite the inner gate. The size and location of such risers should be determined according to the requirements of the microstructure of the castings.

Zhengzhou deoxidizer factory said that deoxidizer as a new food preservation material has it. The deoxidizer absorbs the oxygen in the container and keeps the food in an anaerobic state. However, the raw materials of the deoxidizer must have stable reaction, no strange odor, no harmful gas formation and other side effects. In case of accidental ingestion, it is harmless to human body. The deoxidizer is generally based on iron powder and can be used in general food to keep food products. Quality and prolong shelf life, use in healthy food can prevent oil oxidation, prevent fading and maintain nutrients. More than
