The overall situation of large continuous vertical annealing furnace production line is the core product in the production process, annealing furnace length of 176 m, width 9.2 m, 27.4 m height.Furnace on the various furnace roller installation number as many as 273 root, distribution in the furnace body, which under the location, up and down position permutation has a diameter of 1300 ㎜ ￠, ￠1200 ㎜ and ￠800 ㎜ big rolls.Find is in large scale continuous annealing furnace furnace roller installation projects, with a roller hearth furnace roller variety, furnace roll assembly of parts, the work high above the more installation, pipeline obstacle, process more complex layered characteristics, structure, repeat process for more high impact on the environment, operation large and scattered, and so on questions, severely restricted the project quality and time limit for a project schedule.
rosion resistance is the performance of the seamless steel tube than the other, so 310 s stainless steel pipe in petroleum, chemical industry, electric power, boiler, etc used more extensive.Main application:310s stainless steel is suitable for making various furnace using component, the highest working temperature 1200 ℃, continuous working temperature 1150 ℃.Brand;1 cr25ni20si2 (310 s)Features: austenitic steel, good oxidation resistance and processing property and welding performance.Because of high nickel, the organization is stable, generally after solid solution treatmentPurpose: high temperature furnace tube, heating furnace, roller hearth roller, the highest available to 1200 ℃
