The finishing roll mill unit of a high-speed wire factory adopts a 45° top-crossing cantilever rolling mill designed by Italian DANIELI company, which was put into use in 2015, and its main production wire specifications are Ф5.5 to Ф16mm. The unit is composed of eight rolling mills, and the maximum designed speed of the mill…
The first intelligent project in front of the blast furnace is officially put into operation! This project is ahead of the domestic and international realization of remote and automatic operation of the liquid metal area in front of the furnace, and has become a model project for front furnace operation. Function The robot automatically adds…
This paper introduces the typical high speed bar production process layout and the key equipment of high speed upper steel system The working principle has certain guiding significance to the maintenance and production organization of high-speed bar equipment. With the development of new technology of rolling equipment, the production of bar in steel works has…
After a company’s capacity expansion ladle went online, the quality of molten steel was increased from 290t to 310t, which directly laid the foundation for stable production and excellent production in the steelmaking department. The annual production capacity of the first steelmaking converter increased by 7% to about 630,000 tons. The total annual production capacity…
Continuous feeding: the scrap steel is loaded into the conveyor or rail car with electromagnetic chucks, hydraulic grabs, and baskets, and is automatically and continuously added to the arc furnace from the upper part of the furnace shell on the side of the electrode no.1 and no.2 of the arc furnace. Afters that, the scrap…
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…
