Abstract
The utility model discloses a cooling apparatus of the casting technique, and the utility model is aimed to provide a continuous casting two-cooling chamber casting blank gas cooling apparatus. The apparatus consists of a gas circulating pipeline, a spray nozzle, a control apparatus and a refrigerating apparatus. The utility model can increase the finishing ratio of the casting blank, and the utility model economizes a good deal of water resources, and the utility model economizes production cost. Using the gas as a cooling medium can also increase the visibility of the working place, and the environment is cleaned, and the production safe coefficient is increased.
Description
Technical field
The utility model relates to a kind of casting technique cooling device.More particularly, the utility model relates to a kind of continuous casting two cold chamber strand gas quench system.
Background technology
In the continuous casting production process of steel casting, molten steel still need continue cooling after the crystallizer cooling, and the space of this part cooling is commonly referred to two cold houses.The quality of strand cooling effect in two cold houses is vital to the quality influence of strand.The cooling technology that uses mainly contains following two kinds at present:
First kind is the water cooling technology, and this is the most general cooling scheme, and utilization rate is more than 90% in present two cold house's types of cooling.The water cooling technology is that water is cooked cooling agent, and water injects directly on the strand by nozzle.This technology is simpler, but sprays because of belonging to rigidity, has the casting billet surface sensitive for damages, produce shrinkage cavity and crackle and loose, and water consumption is big, defectives such as nozzle is easily stifled, operating cost height, and the utilization of cooling medium simultaneously is subjected to the restriction of water resource.
Second kind is the aerosol cooling technology, and it is improved in addition on the basis of water cooling technology, promptly adopts two kinds of cooling medium water and gas simultaneously.This technology cooling effect is more better than water cooling technology, but its operating cost is higher, and nozzle quality is had relatively high expectations, and still exists and the same defective of water cooling technology.
Summary of the invention
Primary and foremost purpose of the present utility model is to overcome deficiency of the prior art, and a kind of continuous casting two cold chamber strand gas quench system is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model provides a kind of continuous casting two cold chamber strand gas quench system, comprises pipeline, the nozzle of gas communication, and a controller also is installed on the gas communication pipeline, is used to control the pressure and the flow of gas; A refrigerator is used for refrigerating gas its temperature is reduced.
On the gas communication pipeline of gas quench system, a temperature monitoring can also be installed, be used to monitor cooled gas temperature.
Its middle controller can be one and have the Self controlling valve of regulating parts that refrigerator can be a semiconductor cooling device.Refrigerator can also be a heat exchanger.
Compared with prior art, the beneficial effects of the utility model are:
Adopt gas cooling technology, can reduce cooling stress and concentrate and strand oxide skin, eliminate the face crack of strand and inherent shrinkage cavity, loose defective, thereby improve the strand lumber recovery; Can save great lot of water resources, remove water treatment technology equipment from, save the land used of laying relevant apparatus, save production cost.Using gases can also avoid answering aerosol, the visibility of raising work-yard, clean environment and the raising production safety coefficient of steam formation under the cold climate condition as cooling medium.
Description of drawings
Fig. 1 is the structural representation of gas quench system in the utility model specific embodiment 1.
Fig. 2 be in the utility model specific embodiment 1 gas quench system the using method schematic diagram.
The specific embodiment
With reference to the accompanying drawings, will be described in detail the utility model below.
The structure of gas quench system as shown in Figure 1 in the specific embodiment of the utility model 1.
Continuous casting two cold chamber strand gas quench system comprises pipeline 1, the nozzle 6 of gas communication in the specific embodiment 1, and the controller of installing on gas communication pipeline 12, is used to control the pressure and the flow of gas; Refrigerator 3 is used for refrigerating gas its temperature is reduced.
In the gas quench system of specific embodiment 1, a temperature monitoring 4 also is installed on gas communication pipeline 1, be used to monitor cooled gas temperature, its installation site is between refrigerator 3 and nozzle 6, have a holding wire 5 that temperature signal is passed to refrigerator 3, refrigerator 3 is regulated the size of refrigerating capacity according to temperature information.Holding wire 5 passes to temperature signal controller 2 simultaneously, and controller 2 can be adjusted gas pressure and flow in the pipeline 1 according to temperature signal.
The shape adjustments of the strand that the quantity of nozzle 6 and shape can be processed as required can be circular single hole, also can be rectangle.
Cooling medium adopts the gas of low-pressure, can be air, also can adopt inert gas.Continuous casting two cold chamber strand gas cooled realizes as follows in the utility model: at first make gas pass through a controller 2 through pipeline 1, the flow and the pressure of gas are adjusted at this; Make gas pass through refrigerator 3 then, to reduce the temperature of gas; Molten steel enters two cold houses after crystallizer 7 coolings.Refrigerating gas is injected in strand 8 surfaces by nozzle 6 and cools off, and generates strand product 9.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
