Priced supply of high-quality spray molybdenum

Winder drum spray dry molybdenum Zhangqiu Sheng Machinery Co., Ltd. Winder bottom roll is the maximum speed of the paper machine rollers. Currently, the maximum balancing speed to reach 2800m / min, dynamic deflection requirements are very high, dynamic load roller to reach 60 tons. The production of such rollers in addition to ensure the roll body wall thickness difference, the more important is balancing the balance to be three sections to ensure dynamic deflection is not exceeded, reaching full speed smoothly. Surface coating according to the paper needs are tungsten, molybdenum spraying. Thermal spraying technology is a powder (or wire rod) shaped metal, ceramics, cermet or polymers, using a spray gun is heated to near or slightly above its melting point, and then using compressed air to accelerate these droplets in a molten state, after ejection to surface pretreatment, to obtain the desired coating. As long as the material can be melted without decomposition can be used as coating materials, which may be formed on the substrate to a coating level without significant heating of the workpiece substrate, it does not change the properties of the workpiece to be coated without thermal deformation
