Abstract
The present invention is fast continuous casting process, and belongs to the field of continuous casting technology in non-ferrous metallurgy. The present invention has one increased second molten steel infusing crystallizer, and the fast continuous casting process includes the steps of casting the first crystallizer with the tundish, removing the first crystallizer, setting the second crystallizer and casting the second crystallizer. By increasing the second crystallizer, the present invention realizes the continuous casting and thus has high production efficiency.
Description
Technical field
The invention belongs to the continuous casting technology field in the smelting iron and steel, relate in particular to a kind of fast continuous casting process of trough casting crystallizer.
Background technology
In smelting iron and steel, the molten steel about 1600 ℃ is become steel, the first step is very important.This step carries out under the conticaster operation, makes molten steel cast steel billet, and the crystallizer that injects molten steel is arranged on conticaster top.Crystallizer is used for making solid profile in the continuous casting production process of steel production enterprise, crystallizer is one of most important member of continuous casting installation for casting, and molten steel begins progressively cooling formation steel billet in crystallizer.The key of continuous casting technology is that molten steel in mold base shell is evenly solidified, and casts the high-quality strand.
In casting cycle, tundish is placed in the crystallizer top.Tundish is the container that holds molten steel that connects between molten steel and the crystallizer, and it has decompression, shunting, removes the effect of field trash and storage molten steel.In conticaster, especially in billet caster, crystallizer will just can carry out next step technological operation by overhead traveling crane after casting finishes, and this moment, tundish need wait for that transporting original position again back behind the replacing EO of this crystallizer just can continue casting operation, generally need 15～25 minutes time therebetween, thereby make the time of tundish interruption casting longer, this will reduce the operating efficiency of casting, even can cause the tundish fault, cause heavy losses and delay production.
Summary of the invention
Main purpose of the present invention is to provide a kind of fast continuous casting process.Will just can carry out next step technological operation after instrument such as overhead traveling crane are transported to the conticaster replacing by transporting at continuous casting casting finishing post crystallization device in the prior art, and tundish is transported the deficiency that just can continue to cast back after need waiting for this crystallizer operation end again.
For realizing purpose of the present invention, the technical solution used in the present invention is as follows:
A kind of fast continuous casting process comprises that molten steel injects crystallizer, it is characterized in that this fast continuous casting process after comprising the steps: trough casting first crystallizer shifts out first crystallizer, and second crystallizer of packing into is cast.
Concretely, this fast continuous casting process comprises the steps:
(1) trough casting first crystallizer;
(2) first crystallizer is hung out;
(3) ready second crystallizer is packed into;
(4) trough casting second crystallizer;
(5) second crystallizer is hung out first crystallizer of packing into.
The concrete operations of described step (2) are as follows: tundish stops watering at first closes this first crystallizer cooling water after offing normal, and removes the crystallizer panel then, and the crystallizer suspension ring are installed, and middle hired car is left, and send instrument that first crystallizer is shifted out with hanging.
Describedly hang that to send instrument be overhead traveling crane.
Described concrete operations of closing this first crystallizer cooling water are closed back-water valve (BWV) then for closing the water intaking valve of cooling water earlier.
The concrete operations of described step (4) are as follows: hired car begins casting in the middle of after second crystallizer is packed into, the second crystallizer panel is installed, and is opened the second crystallizer cooling water.
Described concrete operations of opening the second crystallizer cooling water are opened the water intaking valve of cooling water then for opening the back-water valve (BWV) of cooling water earlier.
The main technical points of this fast continuous casting process is to increase a replacement crystallizer, i.e. second crystallizer can be at former crystallizer, and promptly first crystallizer is cast and finished when carrying out next step technological operation, replaces first crystallizer and carries out continuous casting.
After all processing steps are finished, promptly finished a process of changing first crystallizer fast.Replacing for second crystallizer also is same step, at first after tundish finishes to second crystallizer casting, also can utilize the instrument of transporting that this second crystallizer is transported to next step technology place of casting process operates, treat its end of operation transport back again the casting place, first crystallizer of finishing the continuous casting process operation that to transport back is simultaneously packed into, tundish is cast to it again, so constantly repeats above-mentioned steps.
Beneficial effect of the present invention is, by increasing by second crystallizer, has avoided because of waiting for that first crystallizer transports out of the casting tundish and carries out time delays, the rough sledding such as watering, cause heavy losses of being forced to break that next step technological operation causes; Simple to operate, efficient and convenient; The operator can change fast in very short time and finish, and can satisfy the quantity-produced needs fully, has improved production efficiency.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples, so that to purpose of the present invention, feature and advantage are carried out more deep understanding.
Fig. 1 is the flow chart that prior art is changed the crystallizer that is used for continuous casting installation for casting;
Fig. 2 is the flow chart of the embodiment of the invention.
The specific embodiment
As figure, in the casting cycle of iron and steel enterprise's continuous casting process, normal earlier casting first crystallizer of tundish; After casting finished, tundish stopped watering the steel stream of first crystallizer; Close the cooling water of this first crystallizer then, order is to close water intaking valve earlier, closes back-water valve (BWV) again; Then utilize professional tool to remove the panel and the screw of first crystallizer, and on this crystallizer, install suspension ring; At this moment, the instrument that the transports overhead traveling crane that ready second crystallizer is housed has been prepared to put in place; When tundish stop watering off normal after, utilize overhead traveling crane that first crystallizer is transported to next step technology place of casting process and take off ingot operation, treat that its end of operation transports the casting place again back; And first crystallizer is packed ready second crystallizer into after transporting at once; Tundish puts in place to open and waters subsequently, uses professional tool that the panel of second crystallizer is installed; Can open the second crystallizer cooling water after panel installs, order is to open back-water valve (BWV) earlier, opens water intaking valve again; Last tundish second crystallizer of can normally casting.
At this moment, the process of changing first crystallizer is fast finished.Replacing for second crystallizer also is same step, at first after tundish finishes to second crystallizer casting, also can utilize the instrument of transporting that this second crystallizer is transported to next step technology place of casting process operates, treat its end of operation transport back again the casting place, first crystallizer of finishing the continuous casting process operation that to transport back is simultaneously packed into, tundish is cast to it again, so constantly repeats above-mentioned steps, can increase work efficiency more than 80%.
