Abstract

The invention relates to a method for installing and fixing a large lining plate for a metallurgical steel slag treatment hot stuffy tank. The method is characterized in that: plate blanks serving as lining plates lean against an embedded iron plate on the wall of the hot stuffy tank in certain angles and play a role in structure stabilization by using dead weight, and certain gaps are reserved on the plate blanks and the cement tank wall to form a heat insulation layer so as to play a role in protecting the tank wall. At the lower ends of the plate blanks, stop iron and wedge iron are welded close to two sides of the plate blanks by using tank bottom steel plates to form inner wedge and outer stop; and the degree of freedom of the plate blanks is controlled, and the extension of the plate blanks is not affected, so that the stress of the plate blanks is fully released and the influence of expansion with heat and contraction with cold on the lining plate is eliminated. The plate blanks are connected by hooks and iron bars to form a whole. A door shape is welded on an embedded steel plate on the upper part so as to reinforce the upper parts of the plate blanks. The method stabilizes the structure of the lining plate, enables the lining plate to resist impact, reduces the damage rate of the lining plate, prolongs the service life of the lining plate, is convenient for construction, and can save a large amount of fund.

Description

A kind of installing and fixing method of large-scale liner plate

Technical field

The present invention relates to a kind of metallurgical steel slag and handle the installing and fixing method of the large-scale liner plate in hot vexed pond, be applicable to installing and fixing and safeguarding of the hot vexed technology slag heat large-scale liner plate in vexed pond.

Background technology

At present, handling the comparatively advanced method of slag both at home and abroad is hot vexed technology, finish in the hot vexed pond that several volumes of this arts demand are bigger, general volume is 5m*7m*5.4m, because hot slag is about 1400 degree, rapid heat cycle during work, the steel plate amplitude of expanding with heat and contract with cold is bigger, so generally make liner plate with the metallurgical slab of thickness 200 millimeter, every block of liner plate is that the 5m*1.6m*0.2m volume is bigger, and traditional fixing means mainly adopts pre-buried some spiral shell selects on pool wall, holes on the slab, with nut slab is fixed on the pool wall, and slab is upright.Liner plate is installed, and it is bigger to take up room, and stability is also poor, and difficulty of construction is big.Invar slag temperature is higher, and steel billet can cause the damage of cement pool wall near pool wall, and spacing has waste that causes material and the useful volume that influences vexed pond.

Summary of the invention

The present invention seeks to overcome the shortcoming of prior art, a kind of novel fixing means is provided, it both can guarantee the stability of liner plate, can make slab that enough harmomegathus spaces are arranged again, prevent integrally-built damage thereby reach, prolong the work-ing life of liner plate, convenient construction, and can save a large amount of funds.

The technical solution used in the present invention is: some slabs as liner plate are leaned at a certain angle on the pre-buried iron plate of the vexed pond of heat pool wall, utilize its deadweight to play constitutionally stable effect.The slab lower end utilizes steel plate at the bottom of the pond, and near slab outside weld shelves iron, every block of slab is two or more, and steel billet is subjected to can not be near pool wall under the situation of greater impact power, the inboard plug of slab drift, and every block of slab is two or more, and slab is not toppled over to pond central authorities.Wedge overside in the slab bottom forms is controlled the slab degree of freedom like this, does not influence its dilatability again.Connect between the slab, adopt, during installation, successively slab is hung on the last iron bar, be close between the slab, thereby slab is fixed as one by the both sides, slab side of pool wall burn-on respectively one or more hook and iron bar.Door type iron is enclosed within on the iron bar of slab upper end welding, and door type iron is welded on the pre-embedded steel slab, thus fixing slab top.

This large-scale liner plate fixing means, compared with prior art, beneficial effect of the present invention is as follows:

1. the stable of structure played in the deadweight that makes full use of steel billet, mutual restriction between each liner plate, and one-piece construction is good, does not influence the structure of pool wall.

2. slab and cement pool wall leave a fixed gap, form thermofin, thereby play the effect of protection pool wall.

3. utilize installation method of the present invention, controlled the slab degree of freedom, do not influence its stroke again, slab stress is fully discharged, got rid of the influence of expanding with heat and contract with cold, reduced the spoilage of liner plate, prolonged the work-ing life of liner plate liner plate.

4. because this drift that welds behind slab promptly plays fixed action, play a supporting role again, less with material, so saved a large amount of funds, also reduce the space occupancy volume.

5. pool wall is smooth, does not influence any equipment discharging, reduces the damage amount of liner plate.

6. it is simple that manufacture craft is installed, and cost is lower.

Embodiment

Among Fig. 1, some slabs as liner plate (1) are leaned at a certain angle on the pre-buried iron plate (10) of the vexed pond of heat pool wall (6), utilize its deadweight to play constitutionally stable effect.About 250 mm distance are stayed from the vexed pond of heat pool wall (6) in slab (1) bottom, utilize steel plate (5) at the bottom of the pond, near slab (1) outer face down bonding shelves iron (7), every block of slab (1) weldering shelves iron (7) are two or more, steel billet (1) is subjected to can not be near pool wall (6) under the situation of greater impact power, the inboard plug of slab (1) drift (4), every block of slab (1) weldering drift (4) is two or more, and slab (1) is not toppled over to pond central authorities.Wedge overside in slab (1) bottom forms is controlled the slab degree of freedom like this, does not influence its dilatability again.Connect between the slab (1), adopt by slab (1) both sides, side of pool wall (6) burn-on respectively one or more hook (2) and iron bar (3), during installation, successively slab is linked up with on the iron bar (3) that (2) hang over last, slab is close between (1), thereby slab (1) is fixed as one.Door type iron (8) is enclosed within on the iron bar (9) of slab (1) upper end welding, and door type iron (8) is welded on the pre-embedded steel slab (10), thus fixing slab top.
