Abstract
A blast furnace cooling post consists of a cooling post body, a cooling pipe and a grouting base; the grouting base is welded on the cooling post body and the cooling pipe is arranged in the cooling post body; the cooling post body consists of a cooling post steel canister, a cooling post steel chamber, a water chamber cover and a body block which are welded together; the water chamber cover is a red copper extrusion cast, the outside of the cooling post is evenly equipped with a set of grouting channel cams; the cooling pipe is formed by a water outlet pipe and a water inlet spiral pipe which are connected, the outside of the water inlet spiral pipe is equipped with a levo T-shaped threads. Because the cooling post is formed by welding steel and copper and designed with the unique grouting channel, the utility model can save valuable copper and prolong the service life; moreover, the grouting effect on the blast furnace is promoted.
Description
One, technical field:
The utility model relates to a kind of blast furnace furnace wall cooling spare part, specifically a kind of device of repairing blast furnace cooling stave.
Two, prior art:
For improving the work-ing life of blast furnace, on blast furnace cooling stave, bore some blind holes, in blind hole, fill in the blast furnace cooling stud, and with the can of high conductivity mortar in the gap, in cooling stud, inject recirculated cooling water, can make blast furnace furnace wall be continued to reduce temperature like this, reach the purpose that increases the service life.Traditional blast furnace cooling stud main body is that full copper becomes, cooling tube is a steel material, and cooling stud is along with the degree of depth difference that stretches into the furnace wall, envrionment temperature is also different, the work-ing life of each section is also different, precious materials has been wasted at the position of causing, and the position that has has influenced whole service life because of high-temperature capability is not high.Traditional in addition cooling stud is not designed rational grouting road and is made cooling stud irritate discontented in high firehole, influences heat exchange effect.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, both can improve work-ing life, can reduce cost again, and the better a kind of blast furnace cooling stud of cooling performance.
The utility model is achieved in that
This blast furnace cooling stud is by the cooling stud main body, cooling tube and several parts of grouting seat are formed, the grouting seat is welded on the cooling stud main body, cooling tube is contained in the cooling stud main body, it is characterized in that the cooling stud main body is by the cooling stud steel cylinder, cooling stud copper chamber, water box cover, the stifled several parts of main body are welded, on the cooling stud steel cylinder water inlet pipe is arranged, cooling tube is formed by connecting by rising pipe and water inlet spiral tube, outside the water inlet spiral tube, on the garden left-handed T type screw thread is arranged, rising pipe and main body be stifled, and endoporus is close joins, and weld, grout pipe is arranged and give vent to anger stifled on the fixing grouting seat, hole end surface is not less than the cooling stud steel cylinder below 10 millimeters in the fixing grouting seat of distance, there is one group of uniform double wedge in the outdoor garden of cooling stud copper on week, join with fixing grouting seat endoporus cunning in this garden, double wedge top.
Adopt the utility model that following advantage is arranged:
1, the cooling stud main body is three sections and is welded, and adopts steel, common red copper foundry goods and red copper extrusion casting part respectively, has satisfied the requirement of cooling stud in blast furnace wall different depths temperature contrast, has both saved the noble metal material, has prolonged the work-ing life of cooling stud again.
2, have unique grouting channel, the existing slurry passage of leading has terminal vent again, to guarantee the perfusion effect of cooling stud on blast furnace.
Four, description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a blast furnace cooling stud general assembly synoptic diagram;
Five, embodiment:
As shown in the figure, this blast furnace cooling stud is made up of cooling stud main body, cooling tube and grouting seat more than 4 parts, the grouting seat is welded on the cooling stud main body, cooling tube is contained in the cooling stud main body, the cooling stud main body is welded by stifled more than 8 parts of cooling stud steel cylinder 2, cooling stud copper chamber 5, water box cover 7 and main body, water inlet pipe 1 is arranged on the cooling stud steel cylinder, cooling tube is threaded with water inlet spiral tube 6 usefulness by rising pipe 9 and forms, outside the water inlet spiral tube, on the garden left-handed T type screw thread is arranged, rising pipe and main body be stifled, and endoporus is close joins, and welds.Have grout pipe 10 to block up 3 with giving vent to anger on the fixing grouting seat, there is one group of uniform double wedge in the outdoor garden of cooling stud steel cylinder, cooling stud copper that is not less than below 10 millimeters apart from the interior hole end surface of grouting seat on week, and this double wedge pushes up garden and joins with grouting seat endoporus cunning.The cooling stud copper chamber and the water box cover material of cooling stud main body are red copper, and wherein water box cover forms because of working conditions badly adopts red copper extrusion casting.
Claims (2)
1, a kind of blast furnace cooling stud, by the cooling stud main body, cooling tube and several parts of grouting seat are formed, the grouting seat is welded on the cooling stud main body, cooling tube is contained in the cooling stud main body, it is characterized in that the cooling stud main body is by the cooling stud steel cylinder, cooling stud copper chamber, water box cover, the stifled several parts of main body are welded, on the cooling stud steel cylinder water inlet pipe is arranged, cooling tube is formed by connecting by rising pipe and water inlet spiral tube, outside the water inlet spiral tube, on the garden left-handed T type screw thread is arranged, rising pipe and main body be stifled, and endoporus is close joins, and weld, grout pipe is arranged and give vent to anger stifled on the grouting seat, hole end surface is not less than the cooling stud steel cylinder below 10 millimeters in the distance grouting seat, there is one group of uniform double wedge in the outdoor garden of cooling stud copper on week, join with fixing grouting seat endoporus cunning in this garden, double wedge top.
2, blast furnace cooling stud according to claim 1 is characterized in that cooling stud copper chamber and the water box cover material on the cooling stud main body is red copper, and wherein water box cover forms for red copper extrusion casting.
