This article takes the blast furnace as an example to introduce in detail the principles and methods of online monitoring of refractory defects in the blast furnace body, hot blast pipes, and hot blast ports. From coke ovens, rotary kilns, hot blast stoves, and blast furnaces in ironworks, to ladle, converter, ladle, and tundish in…
Raw materials and manufacturing process of graphite electrode Graphite electrode is a kind of high temperature-resistant graphite conductive produced by a series of processes such as kneading, extrusion, baking, impregnatin, graphitization, mechanical processing, etc. using petroleum coke, needle coke as aggregate, coal pitch as binder material. Graphite electrode is an important high-temperature conductive…
Why does steel need to be deoxidized If the molten steel is not deoxidized, the continuous casting billet will not have the correct solidification structure.The high oxygen content in steel can also cause defects such as subcutaneous air bubble and porosity, and aggravate the harmful effect of sulfur.The residual oxide inclusion in the steel will…
Raw materials: What is the raw material used for carbon production? In the production of carbon, the commonly used raw materials can be divided into solid carbon raw materials and binder and impregnating agents. Solid carbon raw material include petroleum coke, pitch coke, metallurgical coke, anthracite, natural graphite, and graphite crushing, etc.; binder and impregnants…
The service life of the blast furnace tuyere affects the normal production directly. The tuyere burn-through caused by the tuyere leakage is the most serious safety production accident in the blast furnace ironmaking production. The tuyere burn-through accident that occurs during normal production of the blast furnace has serious consequences. As the blast furnace continues…

Control rooms centralized and leaves the scene. In the past, each of our production lines would have more than…
Properties And Considerations Of Manufacturing By Continuous Casting Continuous casting manufacture is different from other metal casting processes, particularly in the timing of the process. In other casting operations, the different steps to the process such as the ladling of metal, pouring, solidification, and casting removal all take place one at a time in a…
Direct reduced iron process The direct reduced iron process (DRI) is becoming more and more important in the climate change debate about producing steel with as little CO2 as possible. Learn more about this process in this article. This article provides answers to the following questions, among others: How does the direct…
