Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is mold structure schematic diagram of the present invention.
In figure: 1. crystallizer body, 2. the first water inlet, 3. the second water inlet, 4. the 3rd water inlet, 5. the 4th water inlet, 6. the first delivery port, 7. the second delivery port, 8. the 3rd delivery port, 9. the 4th delivery port, 10. the 5th delivery port, 11. diffluence pass, 12. collection channel.
The specific embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention.
As shown in Figure 1, this wide cut copper ribbon continuous strand crystallizer, comprise crystallizer body 1, in crystallizer body 1, be formed with the crystallization cavity for copper liquid crystallization casting use, the cross sectional shape of crystallization cavity is rectangle, and crystallizer body interior is provided with the cooling duct for cooling water circulation, crystallizer body 1 is provided with water inlet and delivery port, between water inlet and delivery port, by the intrinsic cooling duct of crystallizer, be connected, by the cooling water flowing through in cooling duct, heat taken out of to cooling copper strips strand.
The quantity of the water inlet on crystallizer body 1 is less than the quantity of delivery port.On crystallizer body 1, be arranged side by side four water inlets, be respectively the first water inlet 2, the second water inlet 3, the 3rd water inlet 4, the 4th water inlet 5; Five delivery ports that are arranged side by side on crystallizer body 1, be respectively the first delivery port 6, the second delivery port 7, the 3rd delivery port 8, the 4th delivery port 9, the 5th delivery port 10, and on each delivery port, be all provided with for controlling the valve of water flow, make crystallizer internal cooling structure form five cooling units.The opening that is positioned at the valve at crystallizer body middle part is greater than the opening of the valve that is positioned at crystallizer body both sides, and the water flow that is positioned at the valve at crystallizer body middle part is greater than the water flow of the valve that is positioned at crystallizer body both sides.
Can be according to external temperature situation in season, water flow size to each valve regulates and controls, and realizes segmentation regulation and control, the intensity of cooling of strengthening crystallizer body central region, its middle part is consistent with both sides crystallization rate, thereby makes the crystallization of whole copper strips slab cooling even.
In winter, external temperature is lower, and the natural intensity of cooling of crystallizer body limit portion is large, the valve openings that is positioned at crystallizer body middle part can be tuned up or the valve openings of limit portion is turned down, makes middle part consistent with the intensity of cooling on both sides.The opening of valve that is positioned at crystallizer body middle part summer is less than the opening in winter, thereby the intensity of cooling on middle part and both sides is consistent equally.Guarantee throughout the year, the crystallization of whole copper strips slab cooling is even, guarantees wide cut copper strips slab quality and serialization production.
On crystallizer body 1, water inlet is provided with a component head piece 11, crystallizer body upper water-out mouth place is provided with collection channel 12, each diffluence pass 11 is connected with collection channel 12 by each cooling duct, and collection channel 12 is T-shaped structure channel, is convenient to all directions cooling duct and collects.
And the cooling duct that is positioned at middle part in crystallizer body 1 is more intensive than the cooling duct that is positioned at both sides, the intensity of cooling of strengthening central region, is consistent middle part and both sides crystallization rate.
The inwall of cooling duct is provided with groove or arc salient point or arc groove, and the contact area of increase and cooling water improves cooling effectiveness.Or the inwall that is only positioned at the cooling duct at crystallizer body middle part is provided with groove or arc salient point or arc groove, increases the intensity of cooling at middle part.Wherein, groove is wave shape groove, except increasing intensity of cooling, has also improved the structural strength of crystallizer body.
Valve is magnetic valve, and crystallizer also comprises connected control module and five temperature sensors, and each temperature sensor is located at corresponding water outlet, induces the water temperature at the mouth of a river, and control module is connected with valve.
The water temperature of water outlet is controlled at 30-35 ℃, and the crystallization rate of copper strips strand is good, guarantees wide cut copper strips slab quality.
If the water temperature threshold value setting of water outlet is 33 ℃, when the water temperature of one of them delivery port is higher than 33 ℃, temperature sensor feeds back to control module by temperature signal, control module tunes up this valve openings of control, increase the intensity of cooling of this cooling unit, make the intensity of cooling of each cooling unit of itself and other consistent, thereby guarantee that the crystallization of whole copper strips strand is even.When the water temperature of one of them delivery port is lower than 33 ℃, control module is controlled this valve openings and is turned down, reduces the intensity of cooling of this cooling unit, makes the intensity of cooling of each cooling unit of itself and other consistent.Realize Based Intelligent Control, significantly improved the quality that wide cut copper strips continuous casting is produced, guarantee serialization production, improved production efficiency.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
