Stroke order:? Skimming, horizontal, horizontal, horizontal, vertical lifting, horizontal skimming, horizontal hook, vertical hook, anyway,? Fold horizontally, vertically, vertically, horizontally.
Basic explanation: metal element, symbol Mn, atomic number 25. Silver gray, shiny, strong and fragile. Used for smelting manganese steel and making copper, aluminum and other alloys. Also used as deoxidizer and desulfurizer.
A gray-white multivalent metallic element, usually hard and brittle, similar to iron but nonmagnetic.
Ingredients: manganese ore, potassium permanganate, manganese oxide, pyrolusite, ferromanganese, high manganese steel, metallic manganese, manganese-containing, manganese dioxide, manganese dichloride, manganese hydroxide, electrolytic manganese, manganese nitrate, manganese sulfate, rhodochrosite, potassium permanganate, manganese fertilizer, potassium permanganate, manganese-rich and manganese oxide.
Examples of manganese:
1. This paper introduces the advantages and disadvantages of cutting performance of high manganese steel, expounds the influence on cutting performance of high manganese steel from the aspects of tool material, geometric parameters of tool handle, cutting parameters, cutting force and tool durability, and gives the reasonable cutting conditions of high manganese steel.
2. The cold working characteristics of high manganese steel, the characteristics and development of explosive hardening technology are briefly introduced.
3. Multi-shaped spring steel wire skeleton was cast in high manganese steel casting by dispersion casting process, and composite test bar was obtained after casting.
4. Through the explosion hardening experiment of high manganese steel, a safe insensitive explosive suitable for explosion hardening was screened out.
5. The causes of fracture of microalloyed high manganese steel liner are analyzed.
6. The situation of high strength and toughness bainite steel frog, high manganese steel and similar products abroad is introduced.
7. The results show that under the conditions of abrasive cutting and small impact load, medium manganese white cast iron samples and liners have better wear resistance and less wear than high manganese steel.
8. For this reason, high manganese steel grinding roller and grinding ring materials are used in raymond mill for steel slag to adapt to the grinding characteristics of steel slag, and good technical results have been achieved.
9. High manganese steel for large rollers in open-pit coal mines belongs to difficult-to-machine materials.
10, high manganese steel surfacing, suitable for surfacing of impact wear parts such as crushers.
