Abstract

The invention discloses a furnace roller temperature field and heat roller type prediction method for a furnace section of a continuous annealing unit. According to relevant heat transfer theory parameters of a furnace roller and roller type parameters, temperature field distribution of the furnace roller and a heat roller type can be figured out on the condition that set temperature of a technology section and strip steel temperature are known, and the guidance effect is realized for high-speed stable operation of the continuous annealing unit.

Description

technical field [0001] The invention relates to a temperature prediction method for continuous annealing equipment, more specifically, to a method for predicting the temperature field of furnace rollers in the furnace section of a continuous annealing unit and the shape of hot rollers. Background technique [0002] In the cold rolling production process, CAPL has gradually become an important part of the cold rolling production organization, and the equipment stability of the furnace section directly affects the operation of the CAPL unit. At present, deviation and hot warp are two major problems affecting the high-speed and stable plate passing of the continuous annealing unit. To reduce the incidence of deviation and hot warp, it is necessary to strictly set the tension according to the furnace roller profile and annealing temperature in the furnace section. Control, in general, the annealing temperature is given with the steel type. Therefore, the temperature field distr...
