Blast furnace carbon block pre-assembly and inspection methods

Apr 11,2024

Blast furnace carbon block pre-assembly is an important task in the blast furnace construction process. It plays a vital role in ensuring the stability and durability of the blast furnace body. The following will introduce in detail the pre-assembly of blast furnace carbon blocks and their inspection methods.

1. Preparation before pre-assembly

Before pre-assembly of blast furnace carbon blocks, it is necessary to ensure that the quality of the carbon blocks meets the design requirements, the surface is smooth, and there are no defects such as cracks and breakage. At the same time, the pre-assembly site must be cleaned to ensure that the site is flat and free of debris to facilitate the smooth assembly of the carbon blocks.

2. Pre-assembly steps

First, determine the order and combination of carbon blocks based on the design drawings of the blast furnace. Then, special tools are used to assemble the carbon blocks according to the design requirements to ensure that the gaps between the carbon blocks are even and tight. During the assembly process, attention should be paid to the stability and balance of the carbon blocks to prevent the carbon blocks from being deformed or damaged due to uneven stress.

3. Inspection method

After pre-assembly, the carbon blocks need to be thoroughly inspected. First, check whether the arrangement sequence and combination of carbon blocks meet the design requirements; second, check whether the gaps between the carbon blocks are uniform and tight; finally, check whether the carbon blocks have defects such as cracks and damage by tapping, observation, etc.

When inspecting, pay special attention to the stability and balance of the carbon blocks to ensure that the carbon blocks will not fall off or tip over during transportation and installation.

In short, the pre-assembly and inspection of blast furnace carbon blocks is an important task in the blast furnace construction process, and it needs to be carried out in strict accordance with the design requirements to ensure the quality and stability of the carbon blocks. Through reasonable pre-assembly and inspection methods, the stability and durability of the blast furnace body can be effectively improved, providing a strong guarantee for the long-term operation of the blast furnace.
