Supplying a variety of customized high-pressure ring arc furnace bellows compensator

The role of the pressure ring is pressed copper tiles clinging electrodes, so that current flows through the copper tile uniformly through the electrode into the furnace. Pressure ring is composed of two half-circle, very complex internal waterway, cooling water first into the lower chamber, then cycle along the outer cooling chamber from the bottom, then enter the circulation in the ring, and finally discharged. Outer cooling chamber is very narrow, wide inner ring, pressure ring near the fire part of the cooling effect is very good, thus ensuring long life pressure ring. Metal bellows compensator multiple links design, manufacture, installation and operation management and so on. Therefore reliability should also be considered from several aspects. Select the bellows in the heating pipe network to select the materials used, in addition to its efficiency, it should also be considered medium, operating temperature and the external environment, we must also take into account the stress corrosion, water treatment agent, cleaning pipes may impact materials, and on this basis, the bellows material, welding, forming, material cost and performance, pointed out the economic and practical material production optimization bellows. Under normal circumstances, with the bellows material shall meet the following conditions: (1) high elastic limit, tensile strength and fatigue strength, in order to ensure that the bellows work. (2) good plasticity to facilitate the bellows molding, and through subsequent processing (work hardening, heat treatment, etc.), in order to obtain sufficient hardness and strength. (3) Good corrosion resistance, to meet the bellows work in a different environment. (4) good weldability, welding technology to meet the requirements of the production process bellows. For ditch laying heat pipe network, when in low-lying pipe, rain or accidental sewage will be immersed bellows compensation, should be considered, such as iron and more corrosion resistant materials, selection of nickel alloy, high nickel alloys and so on. Since the bellows manufacturing such material prices, we can consider an additional corrosion resistant alloy layer surface only in contact with corrosive media. Compensation reason bellows type fatigue life and failure analysis and design can be seen, both the stability of the displacement of the plane of the bellows, stability and corrosion week with fatigue life. Stability and anti-corrosion metal bellows fatigue life is too low will lead to the
