Zhengzhou Dongsheng Metallurgical New Material Co., Ltd. is very professional in the production process of riser heating agent manufacturers. Today, we will introduce the production process of riser heating agent manufacturers to you. We hope that through our introduction, you can have a deeper understanding of the production process of riser heating agent manufacturers and other issues, and have a better understanding of the different risers with different supply functions of

riser heating agent, their sizes and forms. For alloys with small volume shrinkage during solidification (such as gray cast iron) or alloys without centralized shrinkage holes (such as tin bronze), the main function of riser is to discharge the gas in the cavity and collect the liquid metal mixed with inclusions or oxide film at the front of the liquid flow, so as to reduce the amount of metal on the casting. Defects. This riser is mostly located opposite the inner gate, and its size is not too large. For castings requiring control of the microstructure, the riser can collect the cooled metal liquid in the front of the liquid flow to avoid supercooling structure on the casting. Figure 2 is a single cast piston ring. A small riser is set opposite the inner gate to collect cold metal, and there will be no white mouth group due to the undercooling of the metal. Weaving leads to scrap of castings. The size and location of such risers and the production process of riser heater manufacturers should be determined according to the microstructural requirements of castings.

Welcome you to read :

Henan deoxidizer manufacturers tell you that deoxidizer is not a food additive, it absorbs oxygen in packaging containers through the oxidation principle of iron powder, and it is fast within 0.5-2 working days. Reduce the concentration of oxygen to below 0.01% to ensure that the product is not oxidized and deteriorated. Its reaction is stable. No odor. No harmful gas is generated. No side effects. Because the weight of food is different. The volume of food is different. The material of bags is different. The shelf life is different. The type of deoxidizer used is different. The selected type of deoxidizer must be able to remove the oxygen in bags, otherwise the product will be mildewed.

As a new material for food preservation, deoxidizer has its unique advantages. It is packed in the same container as food. Deoxidizer absorbs oxygen in the container and makes the container anaerobic, so that food can be preserved. However, the raw materials used by Henan deoxidizer producer must have stable reaction, no strange odor and harmful gas formation, in case of eating incorrectly, it is harmless to human body. At present, besides bags, there are also caps. Bags are used for bagged food, while caps are used for bottles, cans and other containers. In recent years, with the development of the food industry and the improvement of packaging materials, deoxidizers have been paid more and more attention in China, and their applications are more and more extensive.

If Zhengzhou Dongsheng Metallurgical New Materials Co., Ltd. prepares this article for you, the "riser heater manufacturer's" Production technology "is helpful to everyone, I hope to collect it, if there are any shortcomings, I hope you can point out to us, so that we can make more progress.
