Description

Steel-making continuous casting technique dummy device
Technical field
The utility model relates to steel-making continuous casting explained hereafter equipment technical field, especially a kind of steel-making continuous casting technique dummy device.
Background technology
The primary raw material of steel-making is to contain the higher molten iron of charcoal or the pig iron and scrap iron and steel.In order to remove the impurity in the molten iron, also need in molten iron, to add the materials such as oxidant, deoxidier and slag making materials, and ferroalloy, to adjust the composition of steel.Out molten steel from converter or refining furnace,, chemical composition suitable when its temperature adjust suitable after, can tap.Molten steel takes off in ingot mould or the continuous casting steel machine through steel ladle, namely obtains steel ingot or continuous casting billet.
Continuous casting workshop section is exactly the production process that the molten steel after the refining is continuously cast into steel billet, and capital equipment comprises panoramic table, tundish, crystallizer, withdrawal straightening machine etc.
The ladle that the good molten steel of refining is housed is transported to panoramic table, after panoramic table turns to pouring position, molten steel is injected tundish, tundish is assigned to molten steel in each crystallizer by delivery port and goes.Crystallizer is one of nucleus equipment of conticaster, and it makes casting forming and rapid solidification and crystallization.Under withdrawal straightening machine and crystallizing vibration device acting in conjunction, dummy device is installed on the withdrawal straightening machine, by dummy device the foundry goods in the crystallizer is pulled out, after cooling, electromagnetic agitation, cut into the slab of certain-length.
Existing dummy device comprises dummy bar, dummy bar head and cooling strip, open water before, dummy device is transported to crystallizer about 25cm suitable for reading place by two cold houses and crystallizer, dummy device is aimed at the delivery port of tundish, begin cast, behind molten steel and dummy device solidification and crystallization, dummy device is with the base shell that forms tractive down, this production technology cooling strip can scratch the copper pipe of crystallizer, so that the service life of copper pipe is about 100 dummy ingot number of times, so that production cost improves greatly, often changing copper pipe also can affect normal production, reduces production efficiency.
The utility model content
The technical problems to be solved in the utility model is: the dummy device that overcomes prior art reduces the technical problem in the service life of crystallizer copper pipe, and a kind of steel-making continuous casting technique dummy device is provided, the service life of energy Effective Raise crystallizer copper pipe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of steel-making continuous casting technique dummy device, comprise dummy bar, dummy bar head, connecting rod, cooling strip and guard shield, described dummy bar head is positioned at the head of dummy bar, connecting rod is installed on the dummy bar head, has the through hole of drawing for connecting rod on the bottom surface of described guard shield, guard shield is arranged on the periphery of connecting rod, places many cooling strips between guard shield and the connecting rod.
Described guard shield is to have four side plates and the cage type that base plate surrounds, and has at least on the side plate in four side plates to have notch.When dummy ingot, molten steel can pass notch and be full of crystallizer, improves cooling effect, forms fast the base shell.
For improving effect, all have notch on four side plates.
The beneficial effects of the utility model are that steel-making continuous casting technique of the present utility model is simple in structure with dummy device, is easy to realize, in the copper pipe service life of energy Effective Raise crystallizer, can reach the dummy ingot number of times more than 300 times.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that steel-making continuous casting technique of the present utility model is used the most preferred embodiment of dummy device;
Fig. 2 is the stereogram that steel-making continuous casting technique of the present utility model is used the guard shield part of dummy device.
Among the figure: 1. dummy bar, 2. dummy bar head, 3. connecting rod, 4. cooling strip, 5. guard shield, 51. side plates, 52. notches, 53. base plates, 6. crystallizer.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As depicted in figs. 1 and 2, the steel-making continuous casting technique of the present utility model most preferred embodiment of dummy device, comprise dummy bar 1, dummy bar head 2, connecting rod 3, cooling strip 4 and guard shield 5, described dummy bar head 2 is positioned at the head of dummy bar 1, connecting rod 3 is installed on the dummy bar head 2, have the through hole of drawing for connecting rod 3 on the bottom surface of described guard shield 5, guard shield 5 is arranged on the periphery of connecting rod 3, places many cooling strips 4 between guard shield 5 and the connecting rod 3.Guard shield 5 all has notch 52 for to have four side plates 51 and the cage type that base plate 53 surrounds on four side plates 51.
During use, molten steel enters crystallizer 6, is full of guard shield 5 and is full of crystallizer 6 by notch 52, forms fast the base shell under the cooling of crystallizer 6, and molten steel cools is solidified with connecting rod 3 in conjunction with after firmly, and dummy bar 1 moves down under traction, thereby realizes continuous casting.
