摘要： A roll-holder cartridge for a three-tube rolling stand with means adapted to release a tube during rolling in case of emergency. The roll-holder cartridge (3) has on both side walls a substantially Y-shaped opening (10) laying with the foot at the vertical axis yoke support so as to be able to pull out the roll-holder cartridge according to a direction coinciding with the horizontal axis of the vertical axis yoke while leaving the support hanging from the fixed structure (13) of the rolling stand. In case of normal maintenance operation, the cartridge (3) is pulled out sideways from the structure of the rolling mill with the yoke support of the vertical axis roll anchored to the cartridge itself, like the other supports of the rolls.

摘要： Method and apparatus to determine the skin-temperature of heat-exchange tubes and to prevent overheating of the heat-exchange tubes in a process gas heater (where extreme conditions prevent obtaining sufficiently-accurate direct thermocouple or pyrometric measurement to reliably prevent such overheating) by calculating the maximum skin temperature of heat-exchange tubes using preferably real-time calculation of the overall heat flux through the walls of the heat-exchange tubes with preferably real-time values of gas composition and gas temperature at the inlet and at the outlet of the tubes to calculate the overall transferred heat; and by periodically measuring the temperature of the gas flowing through each of the heat-exchange tubes, and using the measured gas temperatures for calculating the skin-temperature of all tubes, or of a tube selected for the highest gas temperature using the equation: Q = 2 π L ( Ts - Tg ) / ( ln ro ri Km ) . The highest value of skin-temperature can be used to take corrective actions to avoid tubes overheating.
