Abstract
The utility model discloses a drainage device for steel making, which is characterized by comprising a circular tube, a counter weight, a plug and a draw bar. The counter weight is mounted on the inner lower portion of the circular tube, the plug is mounted on the inner upper portion in the circular tube and connected with the counter weight by the draw bar, and packing drainage agent is filled in other space inside the circular tube. The drainage device for steel making leads the packing drainage agent to be gathered in the tube without being easily flushed by molten steel, when used, the drainage device can be directly mounted in a runner after the runner is repaired, and can be used after a sliding plate is closed. The automatic pouring rate of the drainage device can achieve 95%-100%, can avoid accidents of steel spillage, loss of steel and burning of personnel due to oxygen burning and drainage when the runner cannot realize automatically pouring or is low in pouring rate during steel pouring, and has the advantages of capabilities of avoiding oxygen blowing for drainage, reducing cost, environmental pollution and labor intensity of workers and guaranteeing quality of steel, and the like.
Description
Technical field
The utility model relates to steelmaking equipment, particularly a kind of flow diverter that can guarantee automatic casting when watering steel.
Background technology
For many years, steel-making enterprise is a great problem of steel-making enterprise watering aspect the steel all accidents of can not automatic casting and causing always, though novel drainage agent has been arranged, washed away by molten steel but still exist because of the drainage agent, or stand and stay slag before not dropping into new drainage agent, to flow into the mouth of a river earlier when wrapping, so casting rate does not still reach problems such as peak demand.Since can not automatic casting, oxygen drainage, the pipe and the oxygen that not only need a large amount of burning oxygen to use must be burnt, increased spending, cause waste, and operator's safety has also been formed certain threat, burn workman's major accident often occurred, simultaneously because of burning oxygen often, time is long, and column jecket during the iron oxide of formation can stop up waters in case open, in passage below the column jecket obstructed and emit steel, so just cause one heat steel all to scrap; Water because of not opening in addition, the molten steel overstand descends too much the steel temperature, also can cause molten steel to melt down.
Summary of the invention
The purpose of this invention is to provide a kind of can make ladle automatic free-opening rate reach 95%-100%, without the oxygen blast drainage, reduce cost, reduce environmental pollution, alleviate working strength of workers and guarantee the steel-making flow diverter of the quality of steel.
For reaching above-mentioned purpose, the utility model provides a kind of steel-making flow diverter, and it comprises pipe, weight, stopper and pull bar; Described weight is installed in bottom in the pipe of described pipe, and described stopper is installed in the pipe internal upper part of described pipe, and the described pull bar of employing is connected between described stopper and the described weight, is full of filler drainage agent in described pipe in other spaces.
Above-mentioned pull bar can be replaced with chain.
Described steel-making flow diverter, wherein, the weight of described weight is 3000 grams.
Described steel-making flow diverter, wherein, described weight adopts cast iron quality.
Described steel-making flow diverter, wherein, the diameter of described stopper is 15～20 millimeters, length is 150～200 millimeters.
Described steel-making flow diverter, wherein, the material of described stopper is selected the magnesium carbon refractory for use.
Described steel-making flow diverter, wherein, described pipe adds the last layer steel pipe for the paper tube crust and adopts the structure of iron sheet end socket.
The flow diverter of the utility model design concentrates in the pipe filler drainage agent, is difficult for being washed away by molten steel, during use, only needs after fixing the mouth of a river flow diverter directly to be adorned in the people mouth of a river, and the slide plate that closes then gets final product; Its automatic casting ratio can reach 95-100%, can stop when watering steel position, the mouth of a river when watering steel can not automatic casting or the low and burning oxygen drainage that causes of casting rate, thereby cause accidents such as emitting steel, badly bleeding and personnel's burn, it has without the oxygen blast drainage, reduce cost, reduce environmental pollution, alleviate working strength of workers and guarantee the characteristics such as quality of steel.
Description of drawings
Further describe the utility model below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model steel-making with flow diverter.
Description of reference numerals: 1-pipe; The 2-stopper; 3-drainage agent; The 4-pull bar; The 5-weight.
The specific embodiment
About the utility model is the application target that reaches above-mentioned and effect and the technological means that adopted, now enumerate preferable feasible embodiment, and shown in the conjunction with figs., details are as follows:
As shown in Figure 1, a kind of steel-making flow diverter of the utility model, it comprises a pipe 1, and described pipe 1 adds the last layer steel pipe for the paper tube crust and adopts the structure of iron sheet end socket, and the diameter of pipe 1 is the same with the filling pipe end diameter and the length of ladle bottom with length.The cylindrical weight 5 that a weight is 3000 grams is equipped with in the bottom in the pipe of pipe 1, and described weight 5 can adopt cast iron quality.At the pipe internal upper part of pipe 1 diameter being housed is that 15～20 millimeters, length are 150～200 millimeters stopper 2, adopts pull bar 4 to be connected between the weight 5 of described stopper 2 and below, is full of filler drainage agent 3 in pipe 1 in other spaces.
Above-mentioned pull bar 4 can be replaced with the chain (not shown).
The material that pipe 1 is adopted can make the refractory material in the pipe 1 be difficult for outflow, guarantees automatic casting ratio.
The material of described stopper 2 is selected the magnesium carbon refractory for use, improves refractoriness, guarantees automatic casting ratio.
Press mouth of a river slide plate when watering steel, weight 5 is by gravity fall, and is descending thereby pulling drainage agent 3 drives stopper 2 again, and molten steel is gone out along the orifice flow that stopper 2 draws back, and plays the effect of automatic casting.
Flow diverter is after the mouth of a river of packing into erects ladle, from 5～10 kilograms of drainage agent 3 of top input.
The steel-making of the utility model design makes filler drainage agent concentrate on 1 li of pipe with flow diverter, is difficult for being washed away by molten steel.During use, only need after fixing the mouth of a river flow diverter directly packed in the mouth of a river, the slide plate that closes then gets final product; Its automatic casting ratio can reach 100%, and can stop when watering steel position, the mouth of a river when watering steel can not automatic casting or the low and burning oxygen drainage that causes of casting rate, thereby causes accidents such as emitting steel, badly bleeding and personnel's burn.It has without the oxygen blast drainage, reduces cost, reduces environmental pollution, alleviates the characteristics such as quality that working strength of workers guarantees steel.
Only the above, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, so the change of numerical value or displacement of equivalent elements such as, or, all should still belong to the category that the utility model patent contains according to equalization variation and modification that the utility model claim is done.
