Modular installation method for vertical annealing furnace

Abstract

The invention discloses a modular installation method for a vertical annealing furnace. The method includes the following steps of performing modular design on the vertical annealing furnace, settingcenter lines and a level point of the annealing furnace before installation, and performing modular installation on a preheating section, a heating section, a slow cooling section and a quick coolingsection of a furnace shell in sequence, wherein the longitudinal and transverse center lines and the level point are arranged at the bottom of the annealing furnace, and then permanent longitudinal and transverse auxiliary center lines and a permanent level point are arranged on a top platform of the annealing furnace. The modular installation of the preheating section, the heating section and theslow cooling section of the furnace shell involves installation of a lower furnace bottom chamber, multiple sections of furnace middle chambers and an upper furnace top chamber. The modular installation of the quick cooling section of the furnace shell involves installation of an upper furnace-shell quick cooling section body, the furnace top chamber and a lower furnace-shell quick cooling section body. The working efficiency is improved through modular installation. By projecting a furnace bottom plane installation reference line to the furnace top steel structure platform and adding the auxiliary center lines, the correction reliability and precision of the furnace shell equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of annealing furnace process equipment installation for a cold-rolled product production line, and in particular relates to a modular installation method for a vertical annealing furnace. Background technique [0002] In the cold-rolled automobile sheet production line, the continuous annealing unit, the hot-dip galvanizing unit and the galvanized high-strength steel unit all use the vertical annealing furnace as the main process section. The vertical annealing furnace is mainly installed on a multi-layer process steel structure platform. The annealing furnace of the continuous annealing unit consists of a preheating section (JPF), a heating section (RTF), a soaking section (SF), a slow cooling section (SCS), a fast cooling section Section (RCS), overaging section (OAS), final cooling section (FCS) and water quenching section (WQ), the furnace roof is 31m high, and the furnace length is 161m; the annealing f...
