Structure and sootblowing process of a sootblowing furnace

Many people are unaware of what a flue dust furnace is, its structure, and the blowing process. This article will tell you about it. First, let's look at the applicable scope of the flue dust furnace: In non-ferrous metals, this furnace is suitable for smelting blister copper, recycled copper, nickel secondary matte, and copper-nickel secondary matte.

What to do when the inverter circuit of the crucible is difficult to start

When the crucible is in use, the inverter circuit will be difficult to start. What is the reason for this? What should we do? 1. The water-cooled cable is open, and the copper busbar is burned out due to the output load.

The role of continuous casting flux in casting

The true meaning of casting is not merely the formation of a certain thickness of liquid crystallizer protective slag layer on the upper layer of molten steel in the casting mold to isolate the atmosphere from the erosion of the liquid metal. After completing this task, a certain thickness of protective slag layer is wrapped on the surface of the billet. On the slag interface in the casting mold, a non-metallic casting mold shell is first formed, and then the liquid metal adheres to the inner cavity of the casting mold shell to form a primary metal casting mold shell, which gradually develops and increases its thickness, away from the casting mold copper pipe, forming a casting mold shell with sufficient safety thickness, so that the internal molten steel, figuratively speaking, is wearing a tight-fitting lining on the outer wall of the mold shell. This solid and molten mold shell is equivalent to a

Production process of continuous casting flux

To ensure the rational use of continuous casting flux and fully utilize its role in the continuous casting process to obtain high-quality billets, it must be coordinated with the continuous casting process; otherwise, it is difficult to exert its effect. Generally, continuous casting flux is closely related to the following process factors: maintaining a stable mold powder level, centering the submerged nozzle, appropriate nozzle size and insertion depth, stable withdrawal speed, vibration parameters, etc., combined with the protective slag. The following is an introduction to the production process of continuous casting flux.

The role of continuous casting slag protection

Molds flux is an important part of the initial stage of casting. The liquid mold flux layer not only isolates the air to protect the casting, but also ensures that the mold flux layer is formed between the mold copper tube and the metal billet shell, which seriously affects the heat transfer, the formation of vibration marks, and the quality of the casting surface. Vibration marks are the inevitable product of the up and down vibration of the mold. Understanding the causes of vibration marks and reducing their harm is an important part of controlling the surface quality of castings. Let's learn more about the role of continuous casting flux.

The addition of continuous casting slag protection

In actual production, the quality of slag protection is closely related to the slag operation. The practice of continuous casting in steel plants at home and abroad has proved that even if the selected mold flux is correct, if it is not used correctly, there will be problems with the quality of the billet. When adding mold flux to the mold, the mold flux must be evenly distributed on the surface of the molten steel in the mold. When molten steel surface fluctuation, flow deviation, casting stop and other failures occur during casting, corresponding measures should be taken. Let's learn about the addition operation of continuous casting flux.
