1. The sealing cover plate with the water-cooling embedded pipe type slag iron runner is characterized by comprising a plurality of cover plate units which are mutually connected along the length direction of the slag iron runner; the whole cover plate unit is made of steel castings, the outer surface of the cover plate is a plane, and the heating surface on the inner side is cast with a 'well' -shaped grid; and a cooling water pipe is embedded in the cover plate body.

2. The sealing cover plate with the water-cooling embedded pipe type slag iron runner of claim 1 is characterized in that: and a ceramic fiber blanket is paved on the steel surface of the cover plate unit, and a light heat-insulating fireproof spray coating is sprayed outside the ceramic fiber blanket.

3. The sealing cover plate with the water-cooling embedded pipe type slag iron runner of claim 1 is characterized in that: the cover plate unit is respectively combined with a plurality of slag iron runner embedded steel pieces arranged along the length direction of the slag iron runner, and a sealing structure is formed at the combination position.

Technical Field

The invention relates to a sealing cover plate with a water-cooling embedded pipe type slag iron runner.

Background

The iron-making blast furnace can produce a large amount of smoke and dust in the tapping process and pollute the production field, so that steel enterprises can reduce the pollution of the production process to the environment in order to meet the requirement of clean production, and a sealing cover plate is additionally arranged on a slag iron runner. Because the cover plate is formed by welding steel structures, in practical application, the welding members are often subjected to thermal deformation, welding failure and frequent repair, and the normal use is influenced by the wavy deformation and large-area defect. Due to the manufacturing precision and deformation of the welding components, gaps between the cover plates are large, smoke and dust often emerge from the gaps between the cover plates, and a good sealing effect cannot be achieved.

Disclosure of Invention

In order to solve the defects and shortcomings of the slag iron runner cover plate, the invention discloses a water-cooled embedded pipe type slag iron runner sealing cover plate, wherein a welding component is changed into a steel casting, the integrity of the cover plate is greatly enhanced, the outer surface of the cover plate is a plane, and a 'well' -shaped grid is cast on the inner side heated surface, so that the water-cooled embedded pipe type slag iron runner sealing cover plate not only plays a role of reinforcing ribs, but also plays a great role in enhancing the adhesive force of refractory materials. In addition, on the basis of keeping original labyrinth seal structure form, at the inside pre-buried condenser tube of apron body, the normal during operation of apron leads to water circulative cooling, and the effectual influence that reduces tapping channel high temperature to the apron lets the apron keep normal atmospheric temperature operating condition for a long time and avoids the deformation that the high temperature influence produced to effectively guarantee the sealing performance of apron, prolonged the life of apron.

The sealing cover plate is composed of a plurality of cover plate units which are connected with each other along the length direction of the slag iron runner and used for covering the slag iron runner, and is different from the cover plate units formed by welding components in the prior art, the cover plate units are all formed by steel castings, and the cover plate units are identical in shape.

Furthermore, a ceramic fiber blanket is paved on the steel surface of the cover plate unit, and a light heat-insulating fireproof spray coating is sprayed outside the ceramic fiber blanket.

Further, the cover plate unit is respectively combined with a plurality of slag iron runner embedded steel pieces arranged along the length direction of the slag iron runner, and a sealing structure is formed at the combination position.
