The processing process of graphite electrode

Raw materials: What are the raw materials used for carbon production? In carbon production, the commonly used raw materials can be divided into two types: solid carbon raw materials and binders and impregnants. Solid carbon raw materials include petroleum coke, pitch coke, metallurgical coke, anthracite, natural graphite and graphite crushed, etc.; binders and impregnants include…

There are many types of antioxidants for magnesia carbon bricks, how to choose them correctly?

Magnesia-carbon bricks are alkaline refractory materials made of magnesia and carbon materials, using asphalt or resin as binders. It has the multiple advantages of high refractoriness of magnesia refractories and carbon refractories that are difficult to be wetted by slag and molten steel. Because of its high refractoriness, strong slag erosion resistance, excellent thermal shock…

Comparative analysis of the advantages and disadvantages of top charging electric furnace, continuous horizontal charging electric furnace and quantum electric furnace

Today we make the following comparative analysis on the differences and technical pros and cons of the traditional top-charging electric furnace, continuous horizontal charging electric furnace and quantum electric furnace. Traditional top-loading electric furnace has simple equipment, occupies less land, less investment, flexible and simple operation, and is suitable for diversified scrap steel; however, the…

Robot-Temperature measurement and sampling

The temperature measurement and sampling system uses industrial robots as the platform, combined with robot application technology, detection technology, and robot visual recognition technology to complete the robot’s automatic installation of probes. The automatic measuring gun with the probe extends into the high-temperature molten steel for temperature measurement or sampling, and the probe is automatically…

Water spraying while steelmaking!

steelmaking technology: Water spraying while steelmaking! This is actually a new electrode protection technology developed first in Japan-water spray electrode protection. This technology uses an annular water spray device under the electrode holder to spray water on the surface of the electrode to make the water flow down the surface of the electrode. Above the…
