Abstract
The present invention relates to metallurgical industry technical field of building construction, specifically a kind of large blast furnace furnace bottom closes the following refractory material grout construction method of steel plate, i.e., the construction method of the refractory material perfusion between furnace bottom closing steel plate and blast furnace concrete foundation face.After Blast Furnace Bottom closes steel plate completion erecting and welding, aperture is perfused for refractory material on steel plate of furnace hearth, position of opening welding perfusion steel pipe, mouth under the mobile feed leakage bucket made is inserted into intrusion pipe upper end, fire resisting grouting material is perfused into funnel with conveying pipeline, stop carrying out other feed leakage bucket conveyings to the feed leakage bucket conveying when the slow blanking of the grouting material in intrusion pipe and feed leakage bucket；All intrusion pipe perfusions are completed, and grouting material cuts off grout pipe after reaching intensity, with circular steel plate welded closure grout hole.The present invention improves pouring quality, accelerates rate of flooding, and pouring quality is good, and charging efficiency is high.
Description
Technical field
The present invention relates to metallurgical industry technical field of building construction, below specifically a kind of large blast furnace furnace bottom closing steel plate
Refractory material grout construction method.
Background technique
Before Blast Furnace Bottom refractory material laying of constructing, need to carry out refractory material to below Blast Furnace Bottom closing steel plate
Masonry, general small blast furnace furnace bottom closing steel plate area is small, and the hearth area for needing refractory material to be in the milk is small, and be in the milk thickness
It is small, it is perfused by closing the direct filler of aperture on steel plate in Blast Furnace Bottom, can satisfy requirement substantially, and large blast furnace furnace bottom seals
It is big to close steel plate area, it is big that Blast Furnace Bottom closes steel plate following refractory material perfusion thickness, pouring quality require it is high, using directly opening
The method of hole perfusion, it is difficult to guarantee that pouring quality, charging efficiency are very low.
Summary of the invention
Present invention seek to address that the above problem, to provide the large blast furnace furnace that a kind of pouring quality is good, charging efficiency is high
Underseal closes the following refractory material grout construction method of steel plate.
The present invention solves described problem, the technical solution adopted is that:
A kind of large blast furnace furnace bottom closing following refractory material grout construction method of steel plate, includes the following steps:
(1) after Blast Furnace Bottom closing steel plate completes erecting and welding, before Blast Furnace Bottom refractory material laying, in State of Blast Furnace underseal
It closes aperture on steel plate to be perfused for refractory material, position of opening welds intrusion pipe；
(2) feed leakage bucket is made, the feed leakage bucket to complete is inserted into intrusion pipe；
(3) subregion piecemeal carries out the perfusion of Blast Furnace Bottom refractory material, with the mobile conveying of electric hoist after a full feed leakage bucket is perfused
Next feed leakage bucket is perfused in pipe, and third is perfused later, and so on, the grouting material in the feed leakage bucket to be perfused at first flows into high
Furnace furnace bottom repeats to be perfused at once after closing steel plate or less；
(4) after all perfusions are completed and reach intensity, intrusion pipe is cut off, welds circular steel plate closure grouting in position of opening
Hole.
The present invention by adopting the above technical scheme, compared with prior art, the feature protruded is:
Pouring quality is improved, rate of flooding is accelerated, pouring quality is good, and charging efficiency is high.
Preferably, the further technical solution of the present invention is:
In step (3), when the grouting material flowing in feed leakage bucket is slow, State of Blast Furnace is vibrated using vibrating head while perfusion
Underseal closes steel plate and intrusion pipe to accelerate blanking velocity, after the grouting material in intrusion pipe and feed leakage bucket stops decline, stops
To the feed leakage bucket conveying, carry out other feed leakage bucket conveyings, with vibrating head vibration Blast Furnace Bottom closing steel plate and intrusion pipe to
Accelerate blanking velocity, until grouting material no longer declines completion perfusion, no dead level substantially increases pouring quality.

Specific embodiment:
Below with reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, therefore, institute
The example of act is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of following refractory material grouting of large blast furnace furnace bottom closing steel plate
Construction method includes the following steps:
(1) after Blast Furnace Bottom closing steel plate completes erecting and welding, before Blast Furnace Bottom refractory material laying, in State of Blast Furnace underseal
It closes aperture on steel plate to be perfused for refractory material, position of opening welds intrusion pipe.
(2) feed leakage bucket is made, the feed leakage bucket to complete is inserted into two rows of intrusion pipes.
(3) perfusion of Blast Furnace Bottom refractory material is carried out using conveying pipeline subregion piecemeal, is used after a full feed leakage bucket is perfused
Next feed leakage bucket is perfused in the mobile conveying pipeline of electric hoist, and third is perfused later, and so on, in the feed leakage bucket to be perfused at first
Grouting material flow into Blast Furnace Bottom closing steel plate below after at once repeat be perfused；When grouting material flowing in feed leakage bucket is slow,
Using vibrating head vibration Blast Furnace Bottom closing steel plate and intrusion pipe to accelerating blanking velocity while perfusion, when intrusion pipe and
After grouting material in feed leakage bucket stops decline, stop carrying out other feed leakage bucket conveyings to the feed leakage bucket conveying, two rows have been in the milk
Subsequent grout pipe is perfused in Cheng Hou according to the method described above, with vibrating head vibration Blast Furnace Bottom closing steel plate and intrusion pipe to accelerate
Blanking velocity, until grouting material no longer declines completion perfusion, no dead level substantially increases pouring quality.
(4) after all perfusions are completed and reach intensity, intrusion pipe is cut off, in position of opening welding circular steel plate closing
Grout hole.
The present invention improves pouring quality, accelerates rate of flooding, and pouring quality is good, and charging efficiency is high.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to use equivalence changes made by description of the invention and its accompanying drawing content, it is intended to be included within the scope of the present invention.
