From May 26th to 28th, the 20th China International Metallurgical Industry Exhibition, co-organized by the China Iron and Steel Association and the Metallurgical Industry Branch of the China Council for the Promotion of International Trade, was held at the Shanghai *** Convention and Exhibition Center. The 16th China International Refractory...

In conventional converter mechanisms with left-right door structures and slide-type slag-blocking tapping, to reduce the production cost of the inner slide bricks, the bottom plate of the slide brick slots in the fixed frame is typically made very thin, typically 10 mm, to ensure the correct height of the inner...

Composition of Refractory Materials in Slide Plate Slag Stopping Systems Using slide plates to stop slag in converter tapping is one of the most advanced methods internationally, yet also the most challenging slag stopping technology. Using this technology, the system's refractory materials primarily consist of five refractory components: the taphole...

With the rapid development of the steel industry, customers' demands for steel quality are increasing. Producing high-quality, technologically advanced, and value-added premium steel products has become an inevitable choice for steelmakers. Steel quality directly impacts steel performance, and reducing slag discharge during the converter tapping process is a crucial step...

Controlling converter (BOF) slag discharge is not only a crucial process technology for improving molten steel quality but also a key measure for reducing steelmaking costs. This article discusses the detrimental effects of converter slag discharge on smelting costs and molten steel quality, and compares the discharge rates of various...

Reducing slag during the converter tapping process is a key aspect of improving molten steel quality. Low-slag or slag-blocking tapping is essential for producing pure steel. Its purpose is to accurately control the molten steel composition, effectively reduce rephosphorization, increase alloying element absorption, and reduce alloy consumption. This helps reduce...

The nominal tonnage of a converter, also known as its nominal capacity, is measured by the average tapping volume of the operating furnaces. For example, a 120-ton converter has an average tapping volume of 120 tons; a 300-ton converter has an average tapping volume of 300 tons. Using the average...

The tilting mechanism of the converter works in a high-temperature and dusty environment. Its characteristics are large tilting torque, high speed ratio, frequent starting and braking, and large dynamic load. Therefore, the following requirements are put forward for the tilting mechanism of the converter: (1) The furnace body can tilt...

The support ring and trunnion support the converter body and transmit tilting torque. The support ring has a rectangular box-like cross-section with vertical ribs welded in the center to increase rigidity. Water cooling reduces thermal stress within the ring. It can be welded from high-quality Q345 steel plates or cast...

The main parameters of the converter are: (1) The nominal tonnage of the converter. (2)The furnace volume ratio. Also known as the volume coefficient, it is the ratio of the working volume (also known as the effective volume) of the converter after bricklaying to the nominal tonnage. It can be...
