On October 31, a factory made a new breakthrough in the industrial test of high-speed steel billet continuous casting. The maximum pulling speed of HRB400 steel with 155*155cm cross-section exceeded 5.7 m/min, breaking the 5.07 m/min set by the plant last year. Minute ultra-high speed record, once again set the highest record of domestic billet…
Contains the inner lining of liquid molten iron, liquid molten steel container and related furnace protection and insulation materials. Specifically, it can be divided into iron ladle lining, converter lining, ladle lining and tundish lining and related supporting taps, sliding There are more than 130 kinds of shaped refractory materials such as nozzles and three…
The role of blast furnace clay The tap hole can be opened and filled many times. The gun mud can keep the hole diameter of the iron hole stable, and the iron can be drawn uniformly, and finally the molten iron slag in the furnace can be cleaned. The hearth can be protected. The performance…
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…
live situation After the mold is installed, in order to check the sealing condition of the mold during the assembly process, it is necessary to conduct a water flow test to see whether the connection and coordination between the various parts are normal, and whether the seal is leaking. I often observe the mold installation…
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…
The rotary kiln is called the heart of the cement clinker line. The quality of the refractory brick lining directly affects the operation of the rotary kiln. Therefore, the lining of the rotary kiln has always been the top priority of the quality control of the entire clinker line. . At a foreign construction site…
Abstract: With the progress of continuous casting industry, steel works in the progress of the process equipment, billet continuous casting machine’s drawing speed is rising steadily. Shanxi Jianbang Industry Group for 160 * 160 small billet caster, in simple equipment modification and process optimization to improve, to achieve the HRB40OE in production process is drawing…
Temperature measurement, oxygen determination and slag breaking are important links in the iron and steel metallurgical process, but at present, they are all done manually in China. The on-site working environment is poor, the labor intensity of workers is high, and the degree of automation is low. In order to adapt to the intelligent development…
Recently, the price of graphite electrode raw materials has risen, and the downstream steel market prices have slowly risen. At the same time, the overall inventory of graphite electrodes in the current market is slowly falling. Both ends of supply and demand are gradually becoming balanced. The graphite electrode market may in a short rebound.…
