Abstract
The utility model relates to a blast furnace water rushing slag runner, which comprises a water rushing slag runner (5). The utility model is characterized in that a groove wall at the dry residual inlet opening of the water rushing slag runner (5) is arranged into a water cooled wall (6). The cooling area of the water cooled wall adopted by the utility model is large, the cooling intensity is greatly improved, the high heating load at the head part of the water rushing slag runner is adapted, the water cooled wall after being reformed can not be deformed, the maintenance cost is saved, and the normal operation of the blast furnace is guaranteed.
Description
Technical field
The utility model relates to a kind of blast furnace flush slag ditch, especially relates to a kind of blast furnace flush slag ditch with water wall.Belong to the steelmaking equipment technical field.
Background technology
The furrow bank of the flush slag ditch that blast furnace is original all directly is welded with steel plate.In the dried slag ingress of flush slag ditch, be subjected to the influence of current in the high temperature of the dried slag that dried slag runner comes and the flush slag ditch, furrow bank herein very easily is out of shape, and breaks, and causes the water in the flush slag ditch to rush down outward.When situation was serious, the dried slag of high temperature flowed out the flush slag ditch, burnt out cable and other equipment under the flush slag ditch, had influence on the blast furnace ordinary production, and working of a furnace shakiness, coke ratio rise, and molten iron cost increases.Therefore each maintenance all needs the furrow bank of herein flush slag ditch is changed, and labour intensity is big and service condition is very undesirable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of blast furnace flush slag ditch that can make the band water wall that the dried slag of flush slag ditch ingress furrow bank can not deform is provided.
The purpose of this utility model is achieved in that a kind of blast furnace flush slag ditch with water wall, comprises the flush slag ditch, and the furrow bank of the dried slag of described flush slag ditch ingress is arranged to water wall.
The blast furnace flush slag ditch of the utility model band water wall, the water coolant that described water wall inside will enter water wall with dividing plate are divided into two backflow forms of ten two tunnel of advancing.
The blast furnace flush slag ditch of the utility model band water wall, the entrance of cooling water of described water wall is connected with the flushing cinder water pipe by the water wall water inlet pipe, the water wall cooling water outlet is connected with the flushing cinder water inlet of flush slag ditch, the flushing cinder water out of flush slag ditch is connected with the flushing cinder water pipe, with the water cooling water wall in the flushing cinder water pipe, form circular flow.
The blast furnace flush slag ditch of the utility model band water wall is provided with the pressure that relief valve control enters the water of water wall on the described water wall water inlet pipe.
The cooling area of the water wall that the utility model adopts is big, has improved cooling intensity greatly, is adapted to the high heat load of flush slag ditch head, and improved water wall can not produce distortion, has saved maintenance cost, has ensured the normal operation of blast furnace.
Description of drawings
Fig. 1 is the vertical view of the blast furnace flush slag ditch of the utility model band water wall.
Fig. 2 is the facade structures synoptic diagram of water wall of the present utility model.
Among the figure: flushing cinder water pipe 1, water wall water inlet pipe 2, relief valve 3, dried slag runner 4, flush slag ditch 5, water wall 6, communicating pipe 7, dividing plate 8.
Embodiment
Referring to Fig. 1, the utility model is a kind of blast furnace flush slag ditch with water wall, be that furrow bank with flush slag ditch 5 dried slag ingress changes 6 coolings of airtight water wall into, this water wall 6 has a plurality of, front and back are arranged at interval, and adjacent 6 usefulness communicating pipe 7 of water wall are coupled together, the entrance of cooling water of water wall 6 is connected with flushing cinder water pipe 1 by water wall water inlet pipe 2, water wall 6 cooling water outlets are connected with the flushing cinder water inlet of flush slag ditch 5, and the flushing cinder water out of flush slag ditch 5 is connected with flushing cinder water pipe 1.Relief valve 3 is set on the water wall water inlet pipe 2.
Referring to Fig. 2, water wall 6 usefulness general steel plates are welded, and the inner water coolant that will enter water wall 6 with dividing plate 8 of water wall 6 is divided into and pair advances ten two tunnel backflow form.
Claims (5)
1. the blast furnace flush slag ditch with water wall comprises flush slag ditch (5), it is characterized in that: the furrow bank of the dried slag of described flush slag ditch (5) ingress is arranged to water wall (6).
2. require 1 described a kind of blast furnace flush slag ditch with water wall as requested, it is characterized in that: the inner water coolant that will enter water wall (6) with dividing plate (8) of described water wall (6) is divided into and pair advances ten two tunnel backflow form.
3. require 1 or 2 described a kind of blast furnace flush slag ditches as requested with water wall, it is characterized in that: the entrance of cooling water of described water wall (6) is connected with flushing cinder water pipe (1) by water wall water inlet pipe (2), water wall (6) cooling water outlet is connected with the flushing cinder water inlet of flush slag ditch (5), and the flushing cinder water out of flush slag ditch (5) is connected with flushing cinder water pipe (1).
4. require 3 described a kind of blast furnace flush slag ditches as requested, it is characterized in that: relief valve (3) is set on the described water wall water inlet pipe (2) with water wall.
5. require 1 or 2 described a kind of blast furnace flush slag ditches with water wall as requested, it is characterized in that: described water wall (6) has a plurality of, and front and back are arranged at interval, connect with communicating pipe (7) between adjacent water wall (6).
