Abstract
The present invention discloses a kind of inserted steel impermeable mouth of a river, belong to continuous casting diligent fire-resistant field of material technology, including the mouth of a river, the described mouth of a river and brick cup matching part are mouth of a river waist, described mouth of a river waist is provided with cannelure, the number of described cannelure is 23, the degree of depth of described cannelure is 10 15mm, width is 10 15mm, the section geometry of described cannelure is arc, the present invention arranges cannelure at mouth of a river waist with the brick cup place of cooperation, realize existing brick cup and mouth of a river chamotte is filled, mouth of a river waist arranges 23 road cannelures, it is sufficient filling with fire-resistant chamotte, reach to build firm purpose by laying bricks or stones, realize the function preventing molten steel from permeating, increase mouth of a river safety in utilization.
Description
Technical field
The present invention relates to continuous casting diligent fire-resistant field of material technology, a kind of inserted steel impermeable mouth of a river.
Background technology
Continuous casting sprue is a kind of continuous casting functional refractory material, also known as tundish immersion filling pipe end, its be connect in bag and
One ladle canal of crystallizer, plays a part conveying and water conservancy diversion molten steel.According to different conticaster technological requirements, the mouth of a river can
Be designed to different contour structures, but generally speaking its common feature be to use brick cup, coordinate with brick cup together with build by laying bricks or stones in centre
The bag bag end, molten steel heart ladle canal from which passes through, and produces continuous casting direct motion and plays crucial important function.
At present, continuous casting sprue structure and installation masonry way, as it is shown in figure 1, by the mouth of a river and the brick cup matched, both
Between typically leave 2-3mm build by laying bricks or stones cooperation gap, this gap use when building by laying bricks or stones fire-resistant chamotte fill enrich.
But, when building by laying bricks or stones due to practice of construction, the technological disparity of operator and construction quality impact, easily bring chamotte
Smear unreal, and cause oozing at the mouth of a river and brick cup gap steel problem, can be owing to oozing steel and uncontrollable time serious, molten steel is from centre
Packet stream goes out development and oozes steel passage and flow at the bottom of tundish bag, burning apparatus, causes more major break down because oozing steel bleed-out time serious.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the present invention is to provide a kind of inserted antiseepage
Molten steel mouth, it is intended to the problem solving the potential safety hazard oozing steel bleed-out existed when existing continuous casting sprue is built by laying bricks or stones.
Its technical scheme solved is, a kind of inserted steel impermeable mouth of a river, including the mouth of a river, and the described mouth of a river and brick cup auxiliary section
Position is mouth of a river waist, and described mouth of a river waist is provided with cannelure.
Wherein it is preferred to, the number of described cannelure is 2-3.
Wherein it is preferred to, the degree of depth of described cannelure is 10-15mm, and width is 10-15mm.
Wherein it is preferred to, the section geometry of described cannelure is arc.
Use technique scheme, at mouth of a river waist, cannelure is set with the brick cup place of cooperation, it is achieved existing brick cup and the mouth of a river
Chamotte is filled, and mouth of a river waist arranges 2-3 road cannelure, is sufficient filling with fire-resistant chamotte, reaches to build firm purpose by laying bricks or stones, it is achieved prevent
The function of molten steel infiltration, increases mouth of a river safety in utilization.
Accompanying drawing explanation
Fig. 1 be in prior art the mouth of a river and brick cup build schematic diagram by laying bricks or stones.
Fig. 2 is the structural representation at the present invention inserted steel impermeable mouth of a river.
Fig. 3 be the present invention inserted steel impermeable mouth of a river with brick cup build schematic diagram by laying bricks or stones.
In figure: 1 mouth of a river, 2 fire-resistant chamotte, 3 brick cups, 4 cannelures.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely, based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As shown in Figure 1 to Figure 3, the present invention provides a kind of inserted steel impermeable mouth of a river, and including the mouth of a river 1, the mouth of a river 1 is joined with brick cup
Closing position is mouth of a river waist, and mouth of a river waist is provided with the cannelure 4 that 2-3 road section geometry is arc.
In the present embodiment, the groove depth of cannelure 4 is 10-15mm, and width is 10-15mm.
The use process of the present embodiment is:
The waist at the mouth of a river 1 coordinates place with brick cup, is provided with 2-3 road cannelure 4, when the mouth of a river 1 is installed on brick cup, in reality
When construction is built by laying bricks or stones, the mouth of a river is smeared tight with the chamotte in brick cup gap, it is to avoid steel and molten steel are oozed from tundish in the mouth of a river and brick cup gap
Outflow development is oozed steel passage and is flowed to the problem at the bottom of tundish bag, not only realizes existing brick cup and mouth of a river chamotte filling effect, especially
It is the 2-3 road cannelure of mouth of a river waist setting, fire-resistant chamotte can be sufficient filling with, reach to build firm purpose by laying bricks or stones, it is achieved prevent steel
The effect of water penetration.
Use technique scheme, at mouth of a river waist, cannelure is set with the brick cup place of cooperation, it is achieved existing brick cup and the mouth of a river
Chamotte is filled, and mouth of a river waist arranges 2-3 road cannelure, is sufficient filling with fire-resistant chamotte, reaches to build firm purpose by laying bricks or stones, it is achieved prevent
The function of molten steel infiltration, increases mouth of a river safety in utilization.
