Reliable plant technology Reliable plant technology Hot metal desulphurisation process Innovative and reliable. On the secondary metallurgy sector, ThyssenKrupp Polysius supplies injection systems for steel treatment in transfer ladles. For example fracture toughness of steel continuously increased over the last decades by decreasing the limits for Sulfur and Phosphor content in the steel. The solutions offered by Primetals Technologies include Sulfur removal, Silicon removal, Phosphor removal, and other specialized processes to reduce contents of Vanadium, Chromium, Titanium, and Manganese. That's why we developed an alternative technology. For Phosphor removal treatment solutions in converter or ladle have been developed and successfully implemented in several plants. The desulphurisation reagents can be injected singly, simultaneously or with a time lag. ThyssenKrupp Polysius also performs the extension, modernisation and optimisation of existing plants.
Desulfurization in Steelmaking. Steelmaking basically involves two consequential processes: an oxidation process performed in the furnace, followed by a. Hot metal treatment allows further to split the complete steelmaking process in separate process steps which are rather Fig Hot metal desulfurization stand.
Desulphurization of iron from the blast furnace is a well-established efficiency of the process that will be of great help for plant engineers to.
Two single stations for deep co-injection of lime and magnesium for HMD.
Hot Metal PreTreatment Plants by Primetals Technologies
The use of well-proven sensors and operating elements enables a smooth, reliable and automatic desulfurization process. Together with failsafe equipment, the powerful control system provides highest safety levels. To extend HMD capability, versatility, and flexibility, co-injection technology can feature different hardware configurations.
The online supervision models cyclically monitor the actual process, calculating the actual condition weight, analysis and temperature of hot metal and slag.
RLZ MOVIES ON NETFLIX
|All important signals are collected and monitored via our new HMI system, thus supporting a simple and systematic operation.
ThyssenKrupp Polysius has developed injection technology for this process for more than 35 years now. In case of disiliconization or dephosphorization iron oxide is commonly used.

M odern iron- and steelmaking is based on econom- ic effectiveness. Is the equipment doing the job for which it was of enhanced processing activities.
Desulphurisation plants from ThyssenKrupp Polysius reliably and precisely reduce the sulphur content of the hot metal. In modern integrated metallurgical plants producing high grade steels, the hot metal desulphurisation takes place outside the blast furnace.
The metallurgical sequence program contains mathematical equations which reflect the regularities of hot metal desulphurisation, so that every individual hot metal batch is desulphurised with the optimum process Injection technology Dispenser with MEPOL system The core system in the ThyssenKrupp Polysius desulphurisation technology is the injection system known by the proprietary name MEPOL. A large refractory-coated impeller rotates in the liquid iron and creates a strong downward vortex.
The most important components of the MEPOL system are pneumatic dispensers with five harmonised measurement and control units for recording, monitoring and controlling all operating parameters that have an influence on the process and the dosing precision. Our comprehensive process control and optimization system for hot metal desulfurization stations improves the desulfurization process to an optimum level.

Intelligent control of the desulfurization process is performed by the application of dynamic process models.
What makes all the difference to steel production in BOF shops is the hot metal desulphurization is done by means of mechanical stirring process in the hot. For the production of high-grade steels, hot metal desulphurisation is absolutely The desulphurisation process precedes the steel treatment in the converter.
Desulphurisation plants from ThyssenKrupp Polysius reliably and precisely reduce the sulphur content of the hot metal.
The treatment process can take place in transfer ladles or torpedo ladles. ThyssenKrupp Polysius has developed injection technology for this process for more than 35 years now.
