Description

Technical Field

[0001] The invention belongs to the technical field of heating furnace water energy saving, and in particular relates to a single-column pipeline insulation prefabricated block and an installation method. Background Art

[0002] The water-cooled beam of the heating furnace is a load-bearing component for the steel billets to enter and exit the furnace and to realize heating in the furnace. It is composed of a steel pipe, an anchor hook welded on the steel pipe, a load-bearing slider and a refractory castable.

[0003] At present, the commonly used method is on-site pouring. The on-site pouring of water beams has the following main disadvantages:

[0004] 1. The iron sheet is relatively thin, and when wrapped, it directly presses against the anchor hook, which cannot ensure the casting thickness requirements;

[0005] 2. The anchor hook directly supports the thin iron sheet. After the heating furnace has been used for a period of time, the anchor hook will oxidize and fall off because there is no castable protective layer;

[0006] 3. The iron sheet is too thin, and you dare not vibrate or hit it with a rubber hammer during construction, which will cause the porosity of the castable to be too large after molding;

[0007] 4. When supporting the iron formwork, it is easy to deform when tied with iron wire, resulting in uneven thickness of the pouring layer, affecting the service life and the overall aesthetics of the poured water-cooled beam.

[0008] 5. The working conditions of refractory castables for water-cooled beams are very harsh. The thickness is relatively thin (generally 50~60mm), and it is only connected and fixed to the water-cooled beams by metal anchor hooks. It is affected by mechanical vibrations, rapid cooling and heating of the furnace when it is shut down and started, and other factors under high temperature conditions. Therefore, the life of refractory castables for water-cooled beams cast on site is generally not high, which restricts the overall life of the heating furnace. Summary of the invention
