Project Introduction
The casting material at the guide plate of the horizontal flue of furnace No. 2 was cleaned and transported, and after the dust and debris were cleaned, the pins were welded, the wire mesh was tied, and the wear-resistant lining was re-cast after asphalt brushing. The construction was carried out during the maintenance of 206B.
The estimated casting volume of the horizontal flue of this project is 6m³, and the construction is strictly in accordance with the material requirements and technical requirements.
Casting material selection: refractoriness is greater than or equal to 1750℃;, after baking at 100℃×24H, the volume density is ≥2.6g/cm3, the flexural strength (110±5℃) is greater than or equal to 10Mpa; the compressive strength (110℃±5℃) is greater than or equal to 80Mpa (the material requires good thermal shock stability and not less than 20 times, and has good resistance to water vapor immersion).
V-shaped pins are made of Φ6mm heat-resistant stainless steel with a material of 06Cr25Ni20. The wire mesh is made of heat-resistant steel bars of the same material Φ6mm.
Make welded steel bar pins (the quantity is calculated based on the total amount of castable material) and apply asphalt protective coating.
Before construction, take isolation and protection measures such as hard isolation and posting safety warnings.
