Problems solved by technology

However, because the burner brick and the burner are connected as one, the burner brick must be removed together with the burner after it is damaged. The deformation of the burner shell makes it difficult to position and install the burner brick, and the construction quality and construction period cannot be guaranteed.

Embodiment Construction

[0018] See Figure 1 to Figure 2 , a method for quickly replacing burner bricks in an annular heating furnace, which comprises the following steps,

[0019] Offline prefabrication of special burner bricks, see figure 1 Shown in 1-1 # , 1-2 # , 1-3 # , 1-4 # . There are four prefabricated parts 1 in total, and each prefabricated part 1 is staggered and connected to avoid gas blow-by due to joints.

[0020] The anchor brick 2 is pre-embedded in the prefabricated part 1, and the fiber paper 5 is wrapped on the surface of the anchor brick 2 before installation and embedding. It is required that the head of the anchor brick 2 must be exposed to the end face of the prefabricated part. figure 2 .

[0021] When the prefabricated block is made, the metal fixing part 4 is inserted, which not only facilitates the installation of the burner brick, but also strengthens the connection between the quick-drying castable and the prefabricated block.

[0022] A slot with a certain dep...

Abstract

The invention relates to a method for maintaining an annular heating furnace, in particular to a method for replacing a burner of an annular heating furnace. A method for quickly replacing burner bricks of an annular heating furnace, which comprises the following steps: offline prefabricating burner bricks; installing prefabricated burner bricks; using quick-drying refractory castables of the same material as the prefabricated burner bricks for on-site integral casting step. The invention is a simple and effective method for rapidly replacing the burner bricks of the heating furnace, which can realize the maintenance and replacement of the burner bricks within one day.

Description

technical field [0001] The invention relates to a method for maintaining an annular heating furnace, in particular to a method for replacing a burner of an annular heating furnace. Background technique [0002] The ring heating furnace is an important heating equipment in the steel pipe factory. The furnace is composed of a preheating section, a heating section and a soaking section. The heated material is passed through the rotation of the trolley at the bottom of the furnace to realize the preheating, heating and soaking of the tube billet. The furnace is heated by mixed gas through 95 burners distributed on the inner and outer walls of the annular furnace. During the infrastructure construction, the 95 burner bricks were all made of plastic ramming, and the furnace wall and furnace roof were built with refractory bricks and hanging bricks respectively. Since the distance between the plastic burner bricks and the furnace roof is only about 230mm, in order to ensure the Th...
