Problems solved by technology

In the past, for the setting of the tension of the continuous annealing unit on site, the method of combining the form with the experience of the operator was adopted, mainly to ensure the stability of the plate, and did not take into account the problem of suppressing the vibration during the operation of the strip, resulting in the strip Because of the vibration and continuous beating of the furnace roll, transverse stripes are formed on the surface of the furnace roll and the strip, which affects the surface quality of the strip

Abstract

The invention discloses an integrated optimization and setting method of tension in a continuous annealing set furnace of a continuous annealing set, belonging to the technical field of continuous annealing. The invention optimizes and sets nine zones of tension, such as a first heating zone, a second heating zone, a third heating zone, a soaking zone, a quench zone, a first ageing zone, a second ageing zone, a third ageing zone and a final cooling zone; on the premise of ensuring that band steel stably penetrates the plate and does not have transverse buckling and pass-line deflection, the invention furthest inhibits band steel vibration, lightens the transverse stripe on the surface of the band steel and improves the surface quality of the band steel. The invention has the advantages that the transverse stripe on the surface of the produced band steel is lighter than that of the band steel produced with the traditional method. The technology of the invention can effectively prevent the band steel from vibrating in the furnace, reduces the incidence of transverse stripes on the surface of the band steel and improves the surface quality of the band steel.

Description

technical field [0001] The invention belongs to the technical field of continuous annealing, and in particular relates to a method for comprehensively optimizing the tension in a furnace of a continuous annealing unit. Background technique [0002] In recent years, with the huge demand of household appliances, automobiles, electronics, construction, shipbuilding, military industry, aerospace and other industries, the strip production industry has developed rapidly. The continuous annealing unit adopts technologies such as rapid heating, high temperature annealing, rapid cooling, and overaging treatment, which can combine the four processes of cleaning, annealing, leveling, and finishing into one, and produce flat products at a lower cost. Products with good straightness, uniform performance and high surface cleanliness have gained rapid development. attached figure 1 It is a schematic diagram of the production process and equipment layout of a typical continuous annealing ...
