Features & benefits of electric arc furnace water-cooled cover ?

The working conditions of the electric arc furnace water-cooled furnace cover are very bad, it is in a high-temperature state for a long time, and is affected by the temperature sudden change, and is subject to the chemical erosion of the furnace gas and powder slagging materials and the mechanical vibration of the furnace cover lifting.

The electric arc furnace water-cooled furnace cover adopts a close-packed tube structure, which greatly reduces the number of furnace shutdowns, repairs and replacements due to various reasons, thereby reducing production costs. A new type of electric arc furnace cover for steelmaking。

Including:

A water-cooled furnace cover with a top center hole is provided with an electrode furnace in the top center, and the sidewall of the electrode furnace cover is fitted on the inner wall of the top center hole.

By directly fitting the sidewall of the electrode furnace cover to the inner wall of the top center hole, the original water-cooled support ring of the furnace cover is eliminated, thereby avoiding the arc leakage caused by the adhesion of cold steel after water cooling, and reducing the entire arc The arcing probability of the furnace at the electrode furnace cover, thereby improving the production efficiency.

In order to improve the service life of the electrode furnace cover, the electrode furnace cover is made of refractory materials. After the electrode furnace cover is made of refractory materials, it can prevent arcing around the electrode furnace cover from damaging it, and improve the service life of the electrode furnace cover. The refractory material can be formed by casting corundum, silicon carbide, silicon oxide, and other materials.

In order to improve the strength of the electrode furnace cover, reinforcing steel bars and steel rings are arranged in the electrode furnace cover, and the reinforcing steel bars are fixedly connected to the steel ring. During manufacturing, the steel enclosure and reinforcing steel bars are put into the mold for making the electrode furnace cover at the same time, and then the refractory material can be poured into the mold. After forming, the reinforcing steel bar and the steel ring can be located inside the refractory material. Strengthen the role of the electrode furnace cover.
