While slag has use in the aftermarket in a variety of applications, its presence as a result of the steel-making 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.
If steel of high quality has to be produced, the most important prerequisite is a slag-free pouring of steel. AMEPA is the worldwide market leader with its electromagnetic slag detection system ESD for ladles with more than 2000 vessels equipped with sensors.
Carryover slag has to be kept under control otherwise one can end up with negative results. With the development of sensor technology, the detection of carryover ladle slag becomes possible at the end of heats. The main advantage of the sensor type is early detection over a human-controlled system.
The utility model relates to a ladle tracking management system in metallurgical steelmaking industry. The ladle tracking management system comprises a crane vehicle-mounted system, a crane route system, a ground processing system and a wireless communication system; the crane vehicle-mounted 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 carry-over

Steel and slag have different features with regard to radiation physics in the infrared spectral range. Thus, by means of an infared camera, it is possible to determine without any contact and in real time which of both materials is the current main constituent of the tapping, respectively the deslagging stream coming out of the converter or an electric furnace.
Based on lots of investigation of the internal and external slag detection technology, ladle-tundish slag detection system using vibration measurements and BP-ANN 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.
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.
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.
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 charge-number, heat-number, steel grade and tap temperature. When used, these data are recorded in the saved text data file.
Ladle slag carry-over detection technology (SCDT) is of important practical significance to steel continuous casting production (CCP), which can effectively improve the casting blank quality ...
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.

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.
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 up-time and operator trust.
D.C. Plasma Arc Recycler. Steel Refining. This furnace was developed as a cost effective alternative to AOD processing for the foundry industry. A 500 kW D.C. plasma arc ladle furnace with 5 ton steel capacity was constructed and then commissioned in June, 1993.
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.
RAMON Science & Technology Co., Ltd. Was founded in 1993 and was the first one to innovate pilot enterprises in Hunan Province in 2008, which is a high-tech software enterprise and a state planning key software enterprise. RAMON specializes in research and development of automatic measurement and control technology in continuous casting process.
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.
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 .
