Abstract

The utility model relates to a drainage device for smelting steels, which comprises a circular pipe. The center of one end in the circular pipe is provided with a drainage rod, and the other end is provided with a drop hammer; the drainage rod and the drop hammer are connected by a chain; the other space in the pipe is filled with material filling drainage agent. The utility model causes the material filling drainage agent to be concentrated in the pipe and to be difficultly rushed by molten steel. When the utility model is used, the drainage device only needs to be directly assembled in a water gap after the water gap is built and a sliding plate is folded. The utility model has 95-100% of the automatic pouring rate, and can avoid the problem in the process of pouring steel that the water gap can not be automatically poured or has low pouring rate to cause oxygen burning drainage so as to result in accidents of steel overflow, steel flow and staff burn. The utility model has the characteristics of needing no oxygen blast drainage, reducing cost, reducing pollution, lightening labor intensity of workers, ensuring the steel quality, etc.

Description

The steel-making flow diverter

The utility model relates to steelmaking equipment, and particularly a kind of steel that waters is the flow diverter that can guarantee automatic casting.

For many years, steel-making enterprise is a hang-up of steel-making enterprise watering aspect the steel all things 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.

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 flow diverter of the quality of steel.

The flow diverter that the utility model relates to comprises a pipe, and end central authorities are provided with the drainage rod in the pipe, and the other end is provided with and drops hammer, described drainage rod with drop hammer between be connected with chain, in managing, be full of filler drainage agent in other spaces.

The weight of drainage rod described in the flow diverter of the utility model design is 250 grams-500 grams; Described drainage rod diameter is 15 millimeters-20 millimeters, and length is 150 millimeters-200 millimeters.

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 packed in the mouth of a river, and the slide plate that closes then gets final product; Its automatic casting ratio can reach 95-100%, 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 the accident of 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.

Further describe the utility model below in conjunction with drawings and Examples

The steel-making that accompanying drawing designs for the utility model structural representation of flow diverter.

Wherein, label 1 is a tube wall, and 2 are the drainage rod, and 3 is chain, and 4 for dropping hammer, and 5 are the drainage agent.

Flow diverter as shown in the figure, iron sheet is made pipe 1 shape, diameter is the same with the filling pipe end diameter and the length of ladle bottom with length, the bottom is equipped with one 500 cylindrical cast iron that restrains and is dropped hammer 4 in the pipe, it is 200 millimeters the husky rod 2 of magnesium that the pipe internal upper part is equipped with one 20 mm dias, length, this rod is connected with iron chains 3 with following garden ball thing, press mouth of a river slide plate when watering steel, cast iron drops hammer by gravity fall, it is descending that thereby pulling drainage agent 5 drives the husky rod of magnesium again, molten steel is gone out along the orifice flow that the husky rod of magnesium draws back, play the effect of automatic casting.

Claims

1, a kind of steel-making flow diverter is characterized in that comprising a pipe, and end central authorities are provided with the drainage rod in the pipe, and the other end is provided with and drops hammer, described drainage rod with drop hammer between be connected with chain, in managing, be full of filler drainage agent in other spaces.

2, flow diverter as claimed in claim 1, the weight that it is characterized in that described drainage rod are 250 grams-500 grams.
