Abstract
The utility model relates to a blast furnace ignition manual device which is mainly applied in the manual ignition of a steel-rolling blast furnace. The manual device comprises a man hole base (1) and a man hole cover plate (5) and is characterized in that a ring-shaped flange (5.1) protrudes downwards from the bottom end surface of the man hole cover plate (5); a ring-shaped groove (1.1) is concave downwards from the top end surface of the man hole base (1) in the position corresponding with the ring-shaped flange (5.1); the ring-shaped flanges (5.1) is embedded in the ring-shaped groove (1.1); and a sealing material (2) is embedded between the ring-shaped flange (5.1) and the ring-shaped groove (1.1). With the adoption of the utility model, the sealing material can not cause the air leakage and escape because of being blew off by the air flow and has good sealing performance even being put in the high temperature environment, thereby improving the operational reliability of the utility model. Therefore, the utility model can improve production and meets the requirement of the blast furnace mass production.
Description
(1) technical field
The utility model relates to a kind of steel-making, steel rolling blast furnace, is specifically related to a kind of high furnace igniting Prosthesis.Be mainly used in the manual ignition of steel-making, steel rolling usefulness blast furnace.Belong to steel-making, steel rolling equipment technical field.
(2) background technology
High furnace igniting manhole is one of visual plant of guaranteeing the blast furnace sealing property.Before the utility model is made, high furnace igniting Prosthesis in the past, its manhole plate bottom face is plate armature, and its structure is as shown in Figure 1.What the trim between its manhole plate and the manhole base adopted is common plane shape trim.Adopt this sealed structure high pressure draft to be easy to the sealing material that is embedded between the described trim is blown the bad race wind that causes leaking.Wind is run in its leakage will directly cause the slow wind of blast furnace, damping down.This brings very big influence to furnace processor, has also greatly influenced steel-making, steel rolling ordinary production.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of air-flow to be not easy the high furnace igniting Prosthesis that the sealing material of trim between manhole plate and the manhole base is blown brokenly,
The purpose of this utility model is achieved in that a kind of high furnace igniting Prosthesis, comprise manhole base and manhole plate, protrude downwards on the described manhole plate bottom face and be provided with collar flange, corresponding to this collar flange, the corresponding position is concaved with annular ditch groove downwards on the described manhole base top end face, described collar flange is embedded in the described annular ditch groove, is equipped with sealing material between described collar flange and the annular ditch groove.
The utility model is by being arranged to the concave-convex type seal form with high furnace igniting Prosthesis's manhole plate and the trim between the manhole base, and suitably deepen gash depth, so just changed the high pressure draft flow direction, and select for use high-quality graphite metallic cover pad as sealing material, air-flow is not easy sealing material is blown brokenly and causes leakage to run wind like this, even under hot environment, also have excellent sealing performance, improved the work reliability of this equipment greatly, improve production output, thereby satisfied the big production needs of blast furnace.
(4) description of drawings
Fig. 1 is high furnace igniting Prosthesis structural representation in the past.
Fig. 2 is the high furnace igniting Prosthesis of a utility model structural representation.
Among the figure: manhole base 1, sealing material 2, trim 3, cover board fixing device 4, manhole plate 5; Groove 1.1, flange 5.1.
(5) embodiment
Referring to Fig. 2, the high furnace igniting Prosthesis that the utility model relates to mainly is made up of manhole base 1, manhole plate 5 and cover board fixing device 4.Described manhole plate 5 usefulness cover board fixing devices 4 are fixedly connected on the manhole base 1.Protrude downwards on described manhole plate 5 bottom faces and be provided with collar flange 5.1, corresponding to this collar flange 5.1, the corresponding position is concaved with annular ditch groove 1.1 downwards on described manhole base 1 top end face, described collar flange 5.1 is embedded in the described annular ditch groove 1.1, is equipped with sealing material 2 between described collar flange 5.1 and the annular ditch groove 1.1.Described sealing material 2 is a graphite metallic cover pad.
Claims (2)
1, a kind of high furnace igniting Prosthesis, comprise manhole base (1) and manhole plate (5), it is characterized in that protruding downwards on described manhole plate (5) bottom face and be provided with collar flange (5.1), corresponding to this collar flange (5.1), the corresponding position is concaved with annular ditch groove (1.1) downwards on described manhole base (1) top end face, described collar flange (5.1) is embedded in the described annular ditch groove (1.1), is equipped with sealing material (2) between described collar flange (5.1) and the annular ditch groove (1.1).
2, a kind of high furnace igniting Prosthesis according to claim 1 is characterized in that described sealing material (2) is a graphite metallic cover pad.
