Embodiment Construction

[0009] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0010] The present invention is successively installed with preheating section 1, heating section and soaking section 2, cooling section 3, equalizing section 4, heat-stretching roll zone 5, furnace nose section 6, zinc pot 7, and cooling section after plating. 8. Finishing machine 9, tension straightening machine 10, roller coating system 11 and strip conveying equipment 14. At the same time, an over-aging section 12 and a secondary cooling section 13 are installed in parallel in the heat stretching roll zone 5.

[0011] The process method of the present invention is briefly described as follows:

[0012] When producing hot-dip galvanized products, the strip steel 15 enters the preheating section 1, the heating section and the soaking section 2, the cooling section 3, the equalizing section 4, and the heat-stretching roll zone 5 of the continuo...

Abstract

The invention belongs to the technical field of metallurgy and relates to production device and technique used both for hot galvanizing and continuous annealing. The device comprises a preheating section, a heating section and a soaking section of a continuous vertical heater, a cooling section, an equalizer section, a hot expansion roller section, a furnace nose section, a zinc pot, a cooling section after plating, a temper mill, a straightening and withdrawal machine, a roller coating system and band steel transmission equipment, and an overaging section and a secondary cooling section are arranged in parallel in the hot expansion roller section. The invention overcomes the problem of single function of hot galvanizing line of the existing continuous vertical heater, and also solves the problem that the added overaging section and secondary cooling section are arranged by utilizing limited space, therefore, not only hot galvanizing products can be produced, but also annealing products with the quality equivalent to that of an independent continuous annealing line can be produced, thus greatly improving the adapting capability of the lines to the market so as to further improve enterprise benefits, and being especially suitable for the improvement of the existing hot galvanizing line.

Description

Technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a device and a process method for dual-purpose production of hot-dip galvanizing and continuous annealing, in particular to a dual-purpose production of hot-dip galvanizing and continuous annealing on an existing continuous vertical furnace hot-dip galvanizing unit Production equipment and process methods. Background technique [0002] In recent years, with the continuous rapid growth of my country's economy, my country has built a large number of continuous hot-dip galvanizing units, which greatly exceeds the demand for hot-dip galvanizing. As a result, the galvanized sheet market continues to weaken, while the annealed sheet market is popular. However, all the existing continuous hot-dip galvanizing lines are specialized hot-dip galvanizing lines and cannot produce annealed plain sheets. Faced with the current market situation, they cannot do anything. They either lose production t...
