Hydraulic cylinder apparatus for controlling roll gap of the rolling stand

摘要

The invention relates to metallurgical equipment, namely means changing or adjusting the roll mills solution. Hydraulic cylinder devices for controlling the rolling stand rolls solution comprises a housing movable relative to the housing the plunger, on whose surface is sequentially coated annular layer high-chromium compounds, aluminum and fluoroplastic coatings secured to the plunger plate to connect the plunger position sensors mounted on the housing, and planted on the plunger interference fit seals, made of a material based on synthetic rubber. The proposed construction of the hydraulic cylinder assumes an increase in corrosion resistance and lowering the coefficient of friction of the rubbing surfaces, which, ultimately, increases the lifetime of the hydraulic cylinder.
