Description
Technical field
The utility model relates to the improvement technology of band steel production unit, is specifically related to a kind of improvement of industrialization Continuous Hot Dip Galvanizing.
Background technology
In the past, industrialization continuously dip coat zinc product was to adopt the different unit of function with the continuous annealing cold-rolled products, did not promptly produce on same lines.
Application number is a kind of continuous hot galvanizing and the multi-functional annealing furnace of the compatible unit of continuous annealing that the Chinese patent of 200620099743.X is introduced, it is characterized in that (heating zone being installed successively in existing Continuous Hot Dip Galvanizing, soaking zone, cooling section, thermotension roller chamber, outlet stove nose, the zinc pot, plating postcooling section) section tipping in parallel has overaging section and secondary cooling section after the cooling section, and in overaging section and secondary cooling section, be equiped with band steel transfer roller, during production continuous annealing cold-rolled products, steel band is through heating zone, after soaking zone and the cooling section, directly enter overaging section and secondary cooling section by parallel arrangement.But there is following defective in actual applications in this patent:
1. only utilized partly existing continuous zinc coating equipment, as heating zone, soaking zone, cooling section, and overaging section and secondary cooling section are newly added equipments, and cost is higher.
2. increasing overaging section and secondary cooling section newly need be than large space, and present Continuous Hot Dip Galvanizing Line layout is generally compact, does not possess the condition that increases overaging section and secondary cooling section.
The utility model content
For solving the existing installation of underusing of prior art existence, make cost higher, it is bigger to increase the equipment requisite space newly, and present Continuous Hot Dip Galvanizing Line layout is generally compact, not possessing increases the problem of volume than the condition of large equipment, the utility model provides the Dualpurpose installation of a kind of compatible continuous hot galvanizing and continuous annealing, can address the above problem well.
Purpose described in the utility model is achieved by the following scheme:
The Dualpurpose installation of a kind of compatible continuous hot galvanizing and continuous annealing, comprise heating zone, soaking zone, cooling section, thermotension roller chamber, outlet stove nose, zinc pot and plating postcooling section successively, at described outlet stove nose place and connect shunting device, its position is positioned at the top of zinc pot, is used for steel band is directly guided to plating postcooling section from outlet stove nose.
To further being improved to of above-mentioned foundation structure, described heating zone, soaking zone, cooling section, thermotension roller chamber, outlet stove nose, shunting device, zinc pot and plating postcooling section are provided with band steel transfer roller completely, along being with the steel direct of travel with a lines arranged in form.
The advantage of the utility model in practice is:
1. made full use of each working zone of existing Continuous Hot Dip Galvanizing, only increasing a shunting device realizes steel band is directly guided to plating postcooling section from outlet stove nose, thereby make to need not galvanized product and directly carry out the transition to cooling section and anneal cold rollingly, reduced equipment cost by this shunting device.
2. the shunting device that is increased is connected in outlet stove nose place, and the position is positioned at the top of zinc pot, and the space availability ratio height can adapt to the compact environment of Production Line Configured.
By simple modifications to existing Continuous Hot Dip Galvanizing, can make existing Continuous Hot Dip Galvanizing have the function of production continuous annealing cold-rolled products, realize utilizing existing Continuous Hot Dip Galvanizing production continuous annealing cold-rolled products, improved the operating rate of unit, and the cost of can reducing investment outlay greatly.In a word, the utility model is simple in structure, easy for installation, cost is low, space availability ratio is high, simple to operate, result of use good.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to structural representation of the present utility model shown in Figure 1, existing Continuous Hot Dip Galvanizing is improved, original Continuous Hot Dip Galvanizing is equipped with heating zone 2, soaking zone 3, cooling section 4, thermotension roller chamber 5, outlet stove nose 6, zinc pot 8 and plating postcooling section 9 successively, and the utility model is its improvements:
At first, at described outlet stove nose 6 places and connect shunting device 7, its position is positioned at the top of zinc pot 8, is used for steel band is directly guided to plating postcooling section 9 from outlet stove nose 6;
Then unit is provided with band steel transfer roller along band steel direct of travel with a lines form completely.
When utilizing the utility model to carry out the continuous hot galvanizing products production, steel band 1 heats in heating zone 2, insulation in soaking zone 3, in cooling section 4, be cooled to the temperature that zincincation requires, after opening roller chamber 5 and outlet stove nose 6 by heat, shown in dotted line, enter zinc pot 8 and carry out pot galvanize, enter at last in the plating postcooling section 9 and further be cooled near room temperature.Above-mentioned processing step is existing continuously dip coat zinc product ordinary production technology.
When utilizing the utility model to carry out the production of continuous annealing cold-rolled products, steel band 1 heats in heating zone 2, insulation in soaking zone 3, in cooling section 4, be cooled to lesser temps according to arts demand, after opening roller chamber 5 and outlet stove nose 6 by heat, directly enter in the plating postcooling section 9 and further be cooled near room temperature by shunting device 7, and not by zinc pot 8.Steel band has been cooled to lesser temps in cooling section 4, thereby can be in the oxidized surface quality that influences of air.
Need to prove; above-mentioned embodiment just to the exemplary illustration of this patent and and non-limiting its protection domain; those skilled in the art can make some local changes to this patent, so long as just available without creative work, all within the protection domain of this patent.
