Jinguo times: when the magnet 122 is directly above the hall sensor 144, the magnetic line weight of the hall sensor 144 becomes 0, and the magnetic line weight in the horizontal direction remains 0; When the magnet 122 continues to slide in the sliding direction, the magnetic wire weight of the hall sensor 144 changes from top to bottom. At this time, the output level of Hall sensor 142 changes from level 0 to level 1. In the intermediate state 32, the output level of Hall sensor 142 and Hall sensor 144 is 11. At this time, the output level of Hall sensor 144 changes from level 1 to level 0. In the sliding state 33, the output level of Hall sensor 142 and Hall sensor 144 is 10. There are many kinds of casting processes, such as sand casting, gravity casting, pressure casting, investment casting and so on. As one of the foundations of modern machinery manufacturing industry, casting has a history of thousands of years. Due to the precipitation of time, the casting process has become a complex process, and each casting process has corresponding process specifications.

The following is the introduction of sand casting process.

① Confirm the casting drawings, including dimensions, materials, precautions, etc., as well as the preliminary work.

② Process digital simulation, Huafeng casting adopts CAE to simulate the feasibility of casting process, so as to prevent casting shrinkage, pore cold shut and other defects from repeatedly returning to the furnace, resulting in time and economic losses.

③ Casting wood mold and pit modeling, casting molding.

④ Molten steel smelting, melting and purifying molten steel to remove impurities in molten steel. Huafeng heavy industry uses LF refining furnace and VD vacuum degassing furnace to purify molten steel, effectively improving molten steel quality, casting performance and users' high-end casting needs.

⑤ Casting composition detection and spectral analysis and detection of casting material composition to ensure that the castings meet the needs of users.

⑥ Casting and cleaning of castings.

⑦ Heat treatment, some castings need heat treatment and quality adjustment, which can be the physical properties of castings,

⑧ Test castings to ensure they are impeccable. There are seven testing systems for casting, including chemical composition testing, mechanical testing, metallographic analysis, NDT testing, molding sand tester, hardness tester, three-dimensional and three-dimensional testing, in which non-destructive testing follows level II UT and Mt.

⑨ Provide casting processing services according to customer needs. Foundry has CNC processing workshops, CNC gantry boring and milling machines, CNC Floor Boring and milling machines, CNC vertical lathes, boring and milling machines, radial drilling machines and other processing workshops, providing overall solutions from rough cast steel to finished products.

Cast steel is a kind of non denatured material made from scrap steel. High manganese steel contains 1.1 ~ 1.4% manganese and can withstand impact wear. It is mainly used for wear-resistant parts of mining machinery and engineering machinery. Low alloy cast steel takes chromium or chromium nickel as the main alloy element, which is used in chemical valve body and steam turbine shell of large capacity power station. The forging ratio is insufficient, the central deformation is small, and the as cast structure is locally retained.
