The Slagman Vibration Slag Detector (VSD) accurately detects the steel/slag transition at the end of every ladle. You''ll know precisely when to end a heat every time. The Slagman VSD is built with simplicity to maximize uptime and operator trust.
Jan 05, 2012· Then, if there is some slag carry over to the ladle, and steel and slag have a low oxidation level, P reversion is again possible. Therefore, in such phosphorus critical cases slag carry over to the ladle should be carefully prevented. That can be done by slag detection–slag stopping system or by EBT, which is stopped before the end of the steel.
Plasma Arc Recycler. Steel Refining. This furnace was developed as a cost effective alternative to AOD processing for the foundry industry. A 500 kW plasma arc ladle furnace with 5 ton steel capacity was constructed and then commissioned in June, 1993.
When slag intensity reaches the set value, sound light alarms will be given, and ladle gate can be closed in time. This design allows KMD LSDS to generate a reliable and accurate slag alarm far in advance of the slag detection of a human operator. So the user can maximize yield while greatly minimize slag carryover.
Ladle furnaces look like smaller versions of EAF furnaces, having three graphite electrodes connected to an arc transformer used for heating the steel. At the bottom of the ladle furnace, typically, there is a pipeline through which argon gas can be injected for stirring and homogenizing the .
Steel slag is a solid waste from steel production. Monocon can provide a range of slag detection cameras as part of the complete slag control package. The Infra Red slag detection camera (shown to the right) is a mean to measure when the level of slag in a metal stream reaches a certain percentage.

the slag detection system to improve the steel transfer process. Data to the slag detection system includes tap number, alarm level and five unique variables specified by the steel plant such as chargenumber, heatnumber, steel grade and tap temperature. When used, these data are recorded in the saved text data file.
Ladle slag carryover detection technology (SCDT) is of important practical significance to steel continuous casting production (CCP), which can effectively improve the casting blank quality ...
While slag has use in the aftermarket in a variety of applications, its presence as a result of the steelmaking process causes substantial time, expense and equipment damage. Until now, it has taken herculean efforts to remove slag. Now, based on recent advances in detection, slag is more reliably and effectively managed.

The utility model relates to a ladle tracking management system in metallurgical steelmaking industry. The ladle tracking management system comprises a crane vehiclemounted system, a crane route system, a ground processing system and a wireless communication system; the crane vehiclemounted system is used for acquiring a ladle position signal and a ladle weight signal and transferring the ...
The Slag Detection System has a robust housing assembly, which views directly the liquid metal stream as the steel is tapped. Key Benefi ts of the Slag Detection System Improved production yield Lower slag content improving steel quality Lower maintenance on BOF/ EAF vessel Reduced energy costs Main Problems of slag carryover
Case: Slag pot / slag ladle made by CHAENG (Great Wall Steel Casting Co.,Ltd) has good property. On July 18, 2008, the Great Wall steel casting signed the first contract of slag pot, under the situation of financial crisis and shrinking market, on the same year on December 12 we signed 13 pcs of slag pot with South Korea''s posco, since 2008 we have signed the contract of more than 50 types of ...
Initial success of the early products for Mould Level Measurement, Tundish Level Measurement and Ladle Slag Detection Systems for Continuous Casting were soon followed by Basic Oxygen Furnace and Electric Arc Furnace Slag Detection Systems. Early in the 1990s, the EMLI Technology was sold to the private sector.

Based on lots of investigation of the internal and external slag detection technology, ladletundish slag detection system using vibration measurements and BPANN analysis of the molten steel vibration signal has been developed. According to the difference between slag and steel feature, the method of slag characteristic parameter identification has been discovered.
The Tozato Slag Detector, for continuous monitoring of metal teeming ladles, is equipped with a very sturdy software that uses a shielded vibration sensor and a high quality optical sensor, giving the system an unique performance in monitoring the slag carryover from the teeming ladle to the tundish.
May 30, 2019· The position of the vessel and the ladle car, the ladle alloying system, the installations for slag detection and the slag stopper are controlled by the software module. Multiple safety functions such as maximum tilting speed, online weight monitoring, and ladle fill level detection are included with Automated Tapping.
