Abstract

The present invention provides a dual-purpose installation for continuous annealing and hot dip plating to produce a continuously annealed steel sheet and a hot dip plated steel sheet by switching process routes in the single installation, and according to the present invention, by installing a bypass facility which leads a steel sheet from a continuous annealing furnace to a water quenching facility without it traveling through a plating pot and a plating facility in the a dual-purpose installation for continuous annealing and hot dip plating, it becomes possible to prevent the steel sheet coming out from the annealing furnace from being exposed to the outside atmosphere and being oxidized during the production of a continuously annealed product and to realize a less expensive dual-purpose installation for continuous annealing and hot dip plating.

Description

The Dualpurpose installation that is used for continuous annealing and hot dip process
Technical field
The present invention relates to a kind of Dualpurpose installation that is used for continuous annealing and hot dip process, in order to the steel sheet of production continuous annealing and the steel sheet of hot dip process by conversion process (processing) route in an individual equipment.
Background technology
Though being designed for separately by general way use so far, the distinct device of purposes comes the steel sheet of production continuous annealing and the steel sheet of hot dip process always, the steel sheet of galvanizing particularly, but in open No.S55-6469 of Japanese unexamined patent or Japanese patent application No.H11-5298, a kind of Dualpurpose installation that is used for continuous annealing and hot dip process or galvanizing is proposed, in order to the steel sheet of production continuous annealing in an individual equipment and the steel sheet of hot dip process.
The open No.S55-6469 of Japanese unexamined patent discloses a kind of Dualpurpose installation that is used for a hot dip process service line and a continuous annealing service line, wherein, when the steel sheet of production continuous annealing, the steel sheet that comes from a continuous annealing furnace cools off in usual atmosphere, and is not immersed in the coating bath.Yet,, will have the problem of surface of thin steel sheet oxidation as not taking some countermeasures because the steel sheet that just comes out from continuous annealing furnace has high temperature.Propose a kind of like this idea, a pickling installation promptly has been set, be used to remove lip-deep oxide film.Yet this needs the optional equipment investment, sewage treatment equipment of new clothes and raising operational load.
Japanese patent application No.H11-5298 discloses a kind of equipment, in order to reducing the steel-sheet temperature in continuous annealing furnace exit fully so that at steel sheet when continuous annealing furnace comes out and be exposed to the outside atmosphere, prevent the steel sheet oxidation.Yet, steel sheet is cooled to one it be exposed to the temperature that oxidation does not take place in the usual atmosphere yet, a bigger cooling apparatus need be arranged in continuous annealing furnace, cause facility investment to increase.
Summary of the invention
The present invention proposes some measures, addressing the above problem and to make a kind of Dualpurpose installation that is used for continuous annealing and hot dip process or galvanizing, so that produce steel sheet not causing under the situation that equipment cost heightens.
The main points that address the above problem of the present invention are as follows:
(1) a kind of Dualpurpose installation that is used for continuous annealing and hot dip process, wherein, at least one continuous annealing furnace, a plating groove, a plater and a granulating unit are along the arranged in form of steel-sheet direct of travel with a machining line, it is characterized in that having one and can make steel sheet directly guide to granulating unit from continuous annealing furnace and be not exposed to the shunting device of outside atmosphere, the inside of this shunting device has remained full of non-oxidizing atmosphere.
(2) a kind of Dualpurpose installation that is used for continuous annealing and hot dip process, it is characterized in that having continued access an alloying furnace of a plating groove and a plater, steel sheet cooling unit or they both, and be equipped with according to above-mentioned (1) described shunting device.
(3) a kind of according to above-mentioned (1) or (2) the Dualpurpose installation that is used for continuous annealing and hot dip process, by this plating groove, this plater and crane are arranged on this shunting device below, can make the equipment in this plater and this plating groove be transported and repair, and production efficiency is improved.
Brief description of drawings
Fig. 1 is a synoptic diagram, shows a kind of Dualpurpose installation that is used for continuous annealing and hot dip process of the present invention of using.
Preferred embodiment
Based on an example the present invention is elaborated below.
Fig. 1 uses a kind of annealing furnace synoptic diagram partly that is used for the Dualpurpose installation of continuous annealing and hot dip process or galvanizing of the present invention.Steel sheet 1 is annealed in continuous annealing furnace 2.When producing plating or galvanizing production, steel sheet 1 is by after the continuous annealing furnace 2, shown in institute's dotted line, is fed to plating groove 3 and by plating.Then, after coating weight was by plater 4 controls, steel sheet stood Alloying Treatment (as required) in alloying furnace 5, by 6 coolings of steel sheet cooling unit, was further cooled near room temperature in granulating unit 7 afterwards.The order of above-mentioned technology (processing) step is identical with the normal process order that is used for production hot dip process or galvanizing product.
When the steel sheet of production continuous annealing, steel sheet 1 will be cooled near room temperature by granulating unit 7, and not by plating groove 3, plater 4, alloying furnace 5 and cooling unit 6.Yet if steel sheet 1 is exposed to outside atmosphere after by continuous annealing furnace 2, the steel-sheet surface is oxidized.For anti-oxidation, be provided with shunting device 8 in the present invention, make steel sheet to be delivered directly to granulating unit 7, and be not exposed to outside atmosphere from continuous annealing furnace 2.
Because the inside of shunting device 8 has remained full of non-oxidizing atmosphere, the composition of this atmosphere for example is the H of 5-10% 2N with 95-90% 2, it is identical with atmosphere in the continuous annealing furnace, so stalloy 1 can be sent to granulating unit 7 and be cooled under not oxidized situation.In addition, by plating groove 3, plater 4 and crane (lifting machine) 9 are set below shunting device 8, make and during production continuous annealing product, can transport and repair the equipment in plating groove, plater or the plating groove, thereby to enhance productivity.
Industrial usability
As mentioned above, by the present invention being applied to for continuous annealing, hot-dip and galvanizing by dipping On the Dualpurpose installation, so that can save be used to the acid of removing the oxide-film on the sheet metal annealing rear surface Cleaning device. In addition, also can during production continuous annealing product, utilize crane to transport and repair plating Equipment in groove, plater and the plating groove, thus enhance productivity.
