Description

End face sealing mechanism for stainless steel water cooling roller Technical Field The utility model relates to the technical field of water cooling roller sealing, in particular to an end face sealing mechanism for a stainless steel water cooling roller. Background Stainless steel water-cooled rolls are often referred to as rotating shaft type components for industrial cooling or transportation, and end face sealing mechanisms such as water-cooled rolls, cooling shafts, etc. are key components to ensure efficient, stable operation thereof, especially in high temperature, high pressure or corrosive medium environments. The movable ring and the water-cooled roller synchronously rotate, and are usually made of stainless steel or hard alloy materials, and the surface of the movable ring and the water-cooled roller is required to have high wear resistance and corrosion resistance. The static ring is fixed on the equipment shell, and is usually made of graphite, silicon carbide or ceramic materials, so that the static ring has good self-lubricating property and high temperature resistance. The existing water-cooled roller way of the continuous casting machine has the defects that the service life of equipment is prolonged, the maintenance amount is increased, the production efficiency is affected, the labor intensity of workers is increased, and the working condition and environment are deteriorated due to high temperature during continuous casting. The prior patent (publication number: CN 203470866U) discloses a water-cooled roller way of a continuous casting machine, a water inlet pipe of the water-cooled roller way extends into the roller through a central through hole of a left roller shaft, a water pipe part positioned in the roller is provided with a row of upward water spraying holes, and the water inlet pipe is fixed on a left bearing cover in a sealing way. The water cooling device has the advantages of simple water cooling structure, long service life of equipment, good site working environment, improved working environment, and contribution to civilized production and production efficiency improvement.
