Abstract
The utility model provides a novel welded split type gun nozzle of a blast furnace. The novel welded split type gun nozzle comprises a gun nozzle body and a gun nozzle cap which are connected with each other, wherein a spigot connecting flange is arranged at one end of the gun nozzle body and the gun nozzle body is connected with a gun body through the spigot connecting flange; a positioning spigot is designed at the other end of the gun nozzle body; and the gun nozzle cap is assembled on the positioning spigot. Compared with the prior art, the novel welded split type gun nozzle of the blast furnace has the technical effects that firstly, the flange of the gun nozzle body is thickened in contrast with the previous design, does not deform, and can be repeatedly used, secondly, in replacement, only the gun nozzle cap needs to be replaced, and as the weight of the gun nozzle cap only accounts for 1/10, the replacement can be carried out very convenient in contrast with the integrated replacement, and thirdly, when the gun nozzle cap is burnt down, only the gun nozzle needs to be replaced, and as the cost of the gun nozzle cap only accounts for 1/13 of the total cost, the expense of 60-70 thousand Yuan can be saved per year for one blast furnace.
Description
Technical field
The utility model relates to technical field of metallurgical equipment, refers in particular to a kind of novel blast-furnace and welds split type big gun mouth.
Background technology
The production of metallurgy industry blast furnace is the continuous process in a limit, after emitting the molten metal of having smelted, need block metal flow and go out duct, extensively makes at present clay gun block up, after mud gun nozzle and duct collision, and requirement fine the blocking of energy and do not ooze out liquid object.But, when blocking up, the big gun mouth need bear very large surging force, simultaneously with high temperature sludge, and liquid metal contact, damage often appears in the big gun mouth.Before the utility model, adopt monoblock type big gun mouth to block up, the big gun mouth more renewed after damage, and be generally the local damage of big gun mouth front end, or behind rear portion flange distortion generation gap, stemming spills.The cost of manufacture of a big gun mouth needs 1300 yuan, and a blast furnace needs with 50 left and right in 1 year, and annual big gun mouth expense is at 65000 yuan.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, detachable, split type big gun mouth of changing is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of novel blast-furnace welds split type big gun mouth, it includes interconnective big gun mouth body and big gun mouth cap, big gun mouth body one end is provided with the seam joint flange, and be connected with barrel by the seam joint flange, the other end is designed with positioning spigot, and big gun mouth cap is assemblied on positioning spigot.
The end that described big gun mouth body is positioned at barrel is provided with the eccentric transition section be tilted to.
Described big gun mouth cap is provided with the big gun mouth seam matched with positioning spigot, and, by this big gun mouth seam location, is assemblied on big gun mouth body.
Compared with prior art, technique effect is a kind of blast furnace welded type big gun mouth that adopts such scheme to provide: the first, the more original design thickening of big gun mouth body flange, not there will be distortion, but Reusability.Only need change big gun mouth cap while the second, changing, weight only accounts for one of 1/10, changes very convenient than monoblock type.Three, when big gun mouth cap burns out, only need to change the big gun mouth just can, big gun mouth cap cost only accounts for one of 1/13 of total cost, a blast furnace can reduce expenses 6～70,000 every year.
The accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is seam joint flange schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, the described novel blast-furnace of the present embodiment welds split type big gun mouth, it includes interconnective big gun mouth body 2 and big gun mouth cap 3, its special big gun mouth body 2 one ends are provided with seam joint flange 4 and bolt hole, can conveniently with barrel is reliable, locates and be connected; The end that big gun mouth body 2 is positioned at barrel is provided with the eccentric transition section 1 be tilted to.The other end is designed with the positioning spigot 5 of smooth flat, and big gun mouth cap 3 is provided with the big gun mouth seam matched with positioning spigot 5, and, by this big gun mouth seam location, electrical pads is soldered to be connected on big gun mouth body 2.By the seam matched, make tight-lipped laminating of iron of big gun mouth cap 3 and big gun mouth body 2, guarantee that stemming does not leak, realization can keep to the side to block up; The big gun mouth body indoor design well-balanced transition that is in line, resistance is little.When big gun mouth cap burns out, only need big gun mouth body be sliced off with the weld seam that the spot welding of big gun mouth cap is connected with cutter, big gun mouth cap is taken down from big gun mouth body, empty the foreign material in big gun mouth body seam, new big gun mouth cap is put in seam, with welding gun spot welding, connect just passable.For guaranteeing that big gun mouth body can repeatedly be used again, the relatively former design thickness of its thickness of flange is thickened, thereby guarantee repeatedly Reusability.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
