Background
Die casting steel pouring is the last step of steel ingot forming, and secondary oxidation and air suction of molten steel can affect the quality of steel ingot products if no measures are taken between a water gap and a bell mouth in the steel pouring process. Therefore, the mold steel ingot production enterprises adopt devices such as argon protective covers and the like, play a role in isolating air and reducing secondary oxidation and air suction of molten steel in the steel casting process, but most of the devices are heavy in design and inconvenient to operate by workers or cannot be used repeatedly.
Disclosure of Invention
An object of the utility model is to overcome exist among the prior art not enough and provide a reduce and water steel in-process molten steel secondary oxidation, breathe in, repeatedly usable alleviates operator's intensity of labour simultaneously, reduce cost's mould cast steel ladle mouth argon protection device.
The purpose of the utility model is realized like this: the utility model provides a mould cast steel ladle mouth of a river argon protection device, includes argon protection device body, is located the base of argon protection device body lower part, is located the argon protection device on argon protection device body upper portion and mouthful, is provided with argon gas around the argon protection device body and stores the storehouse, has seted up argon gas curtain hole on the inner wall of argon protection device body, and the storehouse is stored mutually the switch-on with argon gas in argon gas curtain hole, stores the argon gas and has seted up the argon gas input hole on the storehouse.
The storehouse is stored to the argon gas that argon gas protection device body increased constitutes the inner wall of argon gas protection device body, sets up two-layer evenly distributed's argon gas curtain hole about two-layer on this inner wall.
The aperture of the argon gas curtain hole is between 2 mm and 3mm, and the argon gas curtain hole forms a double-layer argon gas curtain.
The utility model has the advantages as follows:
(1) the steel plate is cut and welded, so that the steel plate can be recycled for many times, and the service life is prolonged;
(2) two layers of air holes are formed in the inner wall of the argon chamber, so that the protection effect of an argon gas curtain is improved;
(3) the uniformity of the air curtain is improved by uniformly distributing the air holes;
(4) the protection device is directly arranged on the pouring gate brick, so that the design is simpler and more convenient and is easier to operate.
Drawings
Fig. 1 is the cross-sectional view of the argon protection device of the die casting nozzle of the utility model.
The labels in the figures are: 1. an upper opening of an argon protection device; 2. an argon gas input aperture; 3. a base of an argon protection device; 4. an argon gas curtain hole; 5. and an argon storage bin.
Detailed Description
As shown in fig. 1, a mould cast steel ladle mouth of a river argon protection device, including the argon protection device body, be located base 3 of argon protection device body lower part, be located the argon protection device of argon protection device body upper portion and go up mouthful 1, be provided with argon gas around the argon protection device body and store storehouse 5, seted up argon gas curtain hole 4 on the inner wall of argon protection device body, argon gas curtain hole 4 stores storehouse 5 with argon gas and switches on mutually, has seted up argon gas input hole 2 on storehouse 5 is stored to argon gas.
The storehouse is stored to the argon gas that argon gas protection device body increased constitutes the inner wall of argon gas protection device body, sets up two-layer evenly distributed's argon gas curtain hole 4 about two-layer on this inner wall. The aperture of the argon gas curtain hole 4 is between 2 mm and 3mm, and the argon gas curtain hole 4 forms a double-layer argon gas curtain.
The argon protection device body is formed by cutting, welding and combining a thin steel plate and a steel pipe. The mould cast steel ladle mouth of a river argon protection device comprises base, upper shed, argon gas input hole, gas storage storehouse, argon gas curtain hole, and the argon gas gets into the argon gas through argon gas input hole 2 and stores 5 rethread inner wall upper and lower two-layer evenly distributed's argon gas curtain hole 4 and gets into in the runner, forms even gas curtain between the mouth of a river under protection device and the ladle, and the protection steel stream reduces secondary oxidation, increases nitrogen at the steel casting in-process.
As shown in figure 1, the argon protection device for the mold casting ladle nozzle consists of a base 3, an upper nozzle 1, an argon input hole 2, an argon gas storage bin 5 and an argon gas curtain hole 4, wherein argon enters the argon gas storage bin 5 through the argon gas input hole 2 and then enters a pouring gate through the argon gas curtain hole 4 uniformly distributed on the inner wall, a double-layer uniform gas curtain is formed between the protection device and the ladle nozzle, and secondary oxidation and nitrogen increase are reduced in the steel casting process of a protective steel flow.
The argon protection device for the die-cast steel ladle nozzle is 90-110mm high, is formed by cutting and welding a Q235B steel plate with the thickness of 3mm, and is required to be tight and uniform in welding line and free of defects such as welding leakage, sand holes and burrs. The inner diameter of the argon inlet hole 2 is 22-27mm, and 2-3mm air holes are uniformly distributed on the middle of the inner side surface and the bottom of the argon storage bin in a circle.
After the hanging casting powder is cast, the fixed end of the argon protection device base is directly installed on a pouring gate, and an operator inserts an argon pipe into an argon input hole during steel pouring to input argon according to the flow of 0.15-0.25Nm 3/min. Argon enters the argon protection device through the input hole and then is filled in the argon storage bin rapidly and flows out from the fine gas curtain holes uniformly distributed on the inner wall, a double-layer argon protection gas curtain is formed between the inner wall of the protection device and the lower nozzle of the steel ladle, and the effects of isolating air and reducing secondary oxidation and nitrogen increase of molten steel in the pouring process are achieved. The argon enters the gas storage bin through the input hole and then enters the space between the ladle lower nozzle and the argon protection device body through the gas curtain holes uniformly distributed on the inner wall, a uniform gas curtain is formed between the protection device and the ladle lower nozzle, and secondary oxidation and nitrogen increase are reduced in the steel casting process of the protection steel flow. And after the steel casting is finished, recovering and cleaning the steel for subsequent continuous use.
