In the process of riser heating agent manufacturer, Zhengzhou Dongsheng Metallurgical New Material Co., Ltd. knows or understands the relevant situation, so that you can know more about the industry besides Zhengzhou Dongsheng Metallurgical New Material Co., Ltd.

deoxidizer, also known as oxygen absorbent or deoxidizer, is called deacidifier in Japan. It can reduce the concentration of oxygen in the prescribed sealed package from 21% to less than 1% in half a day or two days, so as to prevent mildew deoxidizer of various articles and foods from being a fresh-keeping material in food. It has unique advantages. It has the same package as food. In bagging, deoxidizer absorbs the oxygen in the bag, so that the anaerobic deoxidizer and deoxidizer in the bag can be preserved. In case of eating by mistake, it is harmless to human body.

riser with different heating agent supply function, its form, size and location are different, so the design of riser takes into account the properties of casting alloys and castings. For alloys with small volume shrinkage (such as gray cast iron) or alloys without centralized shrinkage (such as tin bronze) during solidification, the main function of riser is to discharge the gas in the mould cavity and collect the liquid metal mixed with inclusions or oxide film at the front of the liquid flow, so as to reduce the defects of the riser heater manufacturer in the process of casting. For castings requiring control of microstructures, risers can collect cooled metal liquid at the front of liquid flow to avoid supercooled structure on the castings. Fig. 2 is a single cast piston ring. A small riser is set opposite the inner gate to collect cold metal. There will be no white structure at this place due to metal supercooling, leading to the scrap of the castings. The location should be determined according to the microstructural requirements of the castings. The above
