Abstract
The utility model provides bag water nozzle blocking device in a kind of continuous casting, comprise mouth of a river plug and with the handle be fixedly connected with bottom the plug of the described mouth of a river, described mouth of a river plug is that top diameter is less than described mouth of a river diameter and base diameter is greater than the cone table of described mouth of a river diameter.When stopper cannot close steel stream, operator can use the utility model manually to close the mouth of a river, prevents molten steel from flowing out and causes bleed-out, guarantees the stable of rhythm of production and reduces the loss of equipment.And this device is simple for production, with low cost, easy to use.
Description
Technical field
The utility model belongs to metallurgical machinery continuous casting installation for casting field, relates to bag water nozzle blocking device in a kind of continuous casting.
Background technology
In continuous casting production process, due to the lifting of the increase casting sequence of production capacity, normal flow control device stopper cannot close steel stream completely under the erosion of molten steel at the end of casting, causes bleed-out accident occurring haveing in tail base process, brings larger economic loss to enterprise.Present iron and steel enterprise generally sets about the erosion of the Mass lost stopper improving stopper and avoids the generation of similar accident by increasing shearing device, these measures not can solve and cannot shut at casting steel stream in latter stage the bleed-out problem brought, and cost is higher simultaneously.
Utility model content
The technical problems to be solved in the utility model is to provide bag water nozzle blocking device in a kind of continuous casting, object be when stopper is acomia shut steel stream steel stream is closed, avoid bleed-out accident occurs.
To achieve these goals, the technical scheme that the utility model is taked is:
Bag water nozzle blocking device in described continuous casting, comprise mouth of a river plug and with the handle be fixedly connected with bottom the plug of the described mouth of a river, described mouth of a river plug is that top diameter is less than described mouth of a river diameter and base diameter is greater than the cone table of described mouth of a river diameter.
Described handle is hollow steel pipe structure.
Described handle is zigzag, and described mouth of a river plug is connected to described handle, at its lower end.
Adopt technique scheme, when stopper cannot close steel stream, operator uses this device manually to close the mouth of a river, prevents molten steel from flowing out and causes bleed-out, guarantees the stable of rhythm of production and reduces the loss of equipment.And this device is simple for production, with low cost, easy to use.
Utilize hollow steel pipe alleviator weight, convenient operation person uses, and reduces labor intensity.
The upper end that operator holds zigzag handle uses the more convenient safety of this device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure:
1, handle; 2, mouth of a river plug.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figure 1, the utility model provides bag water nozzle blocking device in a kind of continuous casting, comprise mouth of a river plug 2 and with the handle 1 be fixedly connected with bottom mouth of a river plug 2.
For top diameter is less than, described mouth of a river diameter and base diameter are greater than the cone table of described mouth of a river diameter to mouth of a river plug 2.Handle 1 is zigzag, is made by hollow steel pipe, lightweight easy to operate.Mouth of a river plug 2 is solid construction, is connected to described handle 1 lower end.
If this device has the mouth of a river cannot closing molten steel after terminating in cast, mouth of a river plug 2 is installed and is blocked in bottom, the mouth of a river by handle 1 position of operating personnel's this device hand-held, prevents molten steel from flowing out and causes bleed-out.Remaining steel stream contact mouth of a river plug 2 quick solidification, makes molten steel flow out, reaches the object of closing steel stream.
Produce 500,000 tons, high-carbon steel calculatings with continuous casting plan, on average connect water 8 stoves, 115 tons of steel poured into a mould by every stove, need produce 540 and to water time, open that to water 2700 streams secondary.After using this device, breakout ratio was reduced to 0.05% by 0.35% of the past in 2013.A stream time bleed-out aggregate losses is about 4.4 ten thousand yuan.Calculate with this, the comprehensive benefit adopting this device to avoid bleed-out to produce every year is about 35.64 ten thousand yuan.And this apparatus structure is simple, easy for installation, invest little, be easy to promote.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
