Requirements for laying clay bricks and magnesia-chrome bricks for the body of submerged arc furnace

Requirements for laying clay bricks for the body of submerged arc furnace:

When laying clay bricks for the body of an submerged arc furnace, it is necessary to select high-quality clay bricks to ensure that their appearance is complete and their size is accurate. Before laying, the surface of the foundation should be cleaned and kept dry. In order to ensure good contact between the clay bricks and the foundation, a suitable adhesive should be used and the laying should be carried out in accordance with the design requirements. During the laying process, the fullness and verticality of the brick joints should be checked at any time and adjusted in time. In addition, in order to improve the thermal insulation performance of the furnace body, it should be ensured that the thickness of the mortar joints between the clay bricks meets the design requirements.

Requirements for laying magnesia-chrome bricks for the body of submerged arc furnace:

Magnesia-chrome bricks are important materials in the body of submerged arc furnace, with the advantages of high high-temperature strength and good wear resistance. When laying magnesia-chrome bricks, high-quality magnesia-chrome bricks should be selected to ensure that their composition, appearance and size meet the design requirements. Like clay bricks, the surface of the foundation should be cleaned and kept dry before laying. The masonry of magnesia-chrome bricks requires the use of special refractory slurry as an adhesive to enhance the bonding between it and the foundation. At the same time, the masonry should be carried out according to the number of layers and thickness required by the design to ensure the flatness and verticality between each layer of bricks. During the masonry process, metal tools such as hammers should be avoided to avoid damaging the surface and performance of magnesia-chrome bricks.

In short, the masonry quality of clay bricks and magnesia-chrome bricks of the furnace body of the submerged arc furnace has an important influence on the performance and service life of the submerged arc furnace. Therefore, the relevant requirements should be strictly observed during the masonry process to ensure that the masonry quality meets the standards and provide protection for the safe and stable operation of the submerged arc furnace.
