Brief: Nous montrons les étapes pratiques et les résultats afin que vous puissiez juger rapidement de l'adéquation. Cette vidéo fournit une présentation détaillée du système de flux thermique d'huile pour rouleau de calandrage en papier Delco, démontrant comment la coque du rouleau de calandre thermique est fabriquée et comment l'huile caloporteuse circule à travers des canaux percés en périphérie. Vous verrez la construction des tourillons de rouleaux, des composants du boîtier de roulement et du système de contrôle de température de précision qui maintient une différence de température de surface de ≤ ± 2 ℃.
Related Product Features:
  • The thermo calender roll shell is manufactured from chilled cast iron for superior durability.
  • Peripherally drilled longitudinal holes allow heat-transferring oil to circulate efficiently through the roll surface.
  • Roll journals are constructed from steel with conical mating surfaces for secure roller bearing mounting.
  • Maintains exceptional surface temperature uniformity with a difference of ≤±2℃ across the roll face.
  • Features spherical roller bearings (23152-FAG type) with cast steel housing and thin oil lubrication.
  • Surface hardness of HV550±20 (HS70±2) with valid hardness depth exceeding 15mm for long service life.
  • Available in diameters from 100-1000mm and roll face lengths from 600-10000mm to suit various applications.
  • Heating system provides precise temperature control with ±1℃ precision and heating rate of 2℃/min from 60-260℃.
FAQ:
  • What materials are used in the construction of the thermo calender roller?
    The roll shell is manufactured from chilled cast iron, while the roll journals are constructed from steel. The bearing housing is made from cast steel, ensuring durability and thermal stability for paper calendering applications.
  • How does the oil thermo flow system maintain temperature uniformity?
    The system features peripherally drilled longitudinal holes that allow heat-transferring oil to circulate through channels to the roll surface. This circulation, combined with precise temperature control, maintains a surface temperature difference of ≤±2℃ across the entire roll face.
  • What are the technical specifications for the bearing system?
    The system includes two spherical roller bearings (type 23152-FAG) with cast steel housing. It uses thin oil lubrication requiring 8L/min flow and includes two rotary joints (Kadant) for efficient operation and easy bearing dismounting using pressurized oil.
  • What temperature range and control precision does the heating system provide?
    The heating system offers a maximum heating-oil temperature of 260℃ with temperature control precision of ±1℃. It provides a controlled heating rate of 2℃/min from 60℃ to 260℃, ensuring gradual and uniform temperature increases.
