Description

A kind of novel slag iron runner revetment and cover plate are supporting

Technical field

This utility model is related to a kind of novel slag iron runner revetment and cover plate is supporting.

Background technology

Blast furnace is the important place of smelting iron and steel.The molten iron of high temperature and slag send into fish along the iron runner of cast house, slag runner Thunder tank and slag ladle.Slag iron ditch is the flow channel of molten iron and slag, and realizes slag sluicing system, normal conditions in flow process Under, slag iron ditch can arrange protection trench cover.

Blast furnace each ferrum mouth alternately taps a blast furnace, and strong temperature change makes slag iron operculum colpi deform greatly.Under conventional situation, overheated Slag iron ditch can transfer heat on cover plate, in order to prevent slag iron trench cover temperature distortion from need to be sprayed and be arranged hollow heat insulation Layer, so resulting in cover plate weight increases, and later period maintenance expense increases, and also brings certain difficulty to daily lifting.Cover plate makes With crane handling and put on slag iron ditch, several tons of the cover plate of weighing can bump to the steel plate of revetment in hoisting process, long and long It, revetment steel plate easily deforms.

And the heat-insulated cover plate of conventional double, it is not provided with air vent, the aerial conduction after being heated is not gone out, and cannot be with cold sky Gas forms convection current, can not bring reducing temperature twice for cover plate.

The slag iron ditch revetment of arrangement at a right angle adopts sheet metal to make, and in order to ensure the planarization of cast house, cover plate is usual It is placed on inside revetment, and cover plate deadweight is born by both sides revetment, in cover plate hoisting process, the cover plate of temperature distortion can be right Revetment causes certain impact, damages revetment, and meanwhile, the cover plate of deformation and revetment also have impact on the smooth and beautiful of cast house entirety See.Blast furnace discharge yard planarizes, cleans the trend becoming current large blast furnace design, and flat cast house facilitates operative employee The arrangement of equipment in people's walking and cast house.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described in detail.

In figure, novel slag iron runner revetment and cover plate corollary system, including cover plate, cover plate is placed in slag iron ditch, slag iron ditch Side be revetment.Described cover plate includes upper plate 1, lower plate 2, and the bottom interval of wherein upper plate 1 is fixed with several isolating bars, preferably Isolating bar is I-shaped steel bar 3, and the stability of I-shaped steel bar 3 is excellent, and lower plate 2 is fixed in the bottom of I-shaped steel bar 3, and lower plate 2 is formed Refractory layer, the wherein space between upper plate 1, lower plate 2 are separated to form the hollow structure with cavity because of I-shaped steel bar, i.e. phase Space between adjacent I-shaped steel bar 3 forms the air cavity region of strip.Air cavity region forms the space of air flow, and air fills Work as insulation medium, reduce the high temperature of the slag iron ditch heat radiation to lid surface steel plate.The empty cavity position corresponding position of hollow structure, Several louvres are arranged on upper plate 1, the setting of louvre can ensure that the circulation of cavity inside heated air, the air of flowing Cooling effect is played to covering plate structure, so that the temperature on cover plate is declined in time.

The both sides of width, in the two ends of upper plate 1, lower plate 2 respectively fixed side 4.Side plate 4 can be thickness is 12mm Steel plate, side plate 4 is fixed on upper plate by way of welding, in lower plate, and side plate 4 maintains stablizing of cover plate entirety vertical direction. What preferably side plate 4 tilted is arranged on upper and lower plate, so that the section between side plate 4 and upper and lower plate is formed trapezoidal, wedge structure Section, and the revetment of slag iron ditch is also configured to the trapezoidal or wedge structure being adapted to side plate, when slag iron trench cover uses crane Handling when putting on slag iron ditch, the slag iron ditch revetment of wedge structure is put into the initial stage in cover plate, and space is big, and both are not susceptible to knock Touch, after centering is put into, cover plate glides under gravity automatically, install and surely lean on.

In this utility model, upper plate thickness is the integral plate between 15-25mm, chooses 20mm thickness in actual use Steel plate, the connection of herringbone steel bar 3 and upper and lower plates also using welding mode it is ensured that the overall firmness of cover plate.

Because lower plate 2 is closest with slag, molten steel, therefore spray heat-resisting castable 6 in the bottom of lower plate 2, it is right to reduce The heat radiation of cover plate steel plate, effectively prevents heat transfer to cast house concrete, it is to avoid be deformed, simultaneously the end of lower plate 2 Anchor 7 is welded on face, forms as one with concrete when pouring into a mould concrete.Lift cover plate for convenience, on upper plate simultaneously Setting hanger 5, and hanger adopts embedded structure it is ensured that the planarization of lid surface.

When this utility model is installed, along slag iron flow direction arrangement, cover plate is covered on slag iron ditch, slag iron ditch and ferrum The thick steel plate of 5mm is laid on the ironworks surface that goes out between factory's slag notch, and slag iron trench cover is all embedded in below earth's surface, cover plate and ground Face is concordant, and seam crossing " fits together perfectly ".In this utility model, below the steel plate of all fixations, weld anchor 6, in cast concrete When form as one with concrete.

Advantage of the present utility model is as follows：

(1) design of slag iron ditch revetment bevel angle, cooperating with trapezoidal decks, (cover plate Cross section Design is tied in echelon Structure), lifting is convenient.

(2) the slag iron ditch revetment of wedge structure is put into the initial stage in cover plate, and space is big, and both are not susceptible to collide with, and centering is put After entering, cover plate glides under gravity automatically, installs and surely leans on.

(3) slag iron ditch revetment is formed using steel plate integral manufacturing, and anchors into one by anchoring piece with cast house concrete Body, meanwhile, in heat-resisting castable in the part spraying of slag iron ditch central side, effectively prevents heat transfer from arriving cast house coagulation On soil, it is deformed.

(4) cover plate adopts double-decker, and air serves as insulation medium, and the high temperature reducing slag iron ditch is to lid surface steel plate Heat radiation, upper plate perforate simultaneously, accelerate the circulation of hot-air, the air of flowing plays cooling effect to cover plate steel construction.

These are only the preferred embodiment of this utility model embodiment, do not implement in order to limit this utility model Example, within all spirit in this utility model embodiment and principle, any modification, equivalent substitution and improvement made etc., all should wrap It is contained in the protection domain of this utility model embodiment.
