Discussion on the damage mechanism and preventive measures of converter bricks

As social competition becomes more and more intense, reducing production costs has become the lifeblood of enterprises. Various copper smelters are constantly exploring ways to reduce the consumption of copper bricks per ton in converters. There are many factors that affect the damage of converter bricks, which are related to factors such as matte grade, […]

Steelmaking – Refining – Control of inclusions in continuous casting steel

With the rapid development of the national economy, the demand for steel has gradually increased, and the quality requirements for steel have continued to increase. Pipelines, bridges, automobiles, shipbuilding, pressure vessels and other industrial production steels require a large amount of steel, and there are also high requirements for the control of inclusion levels. Therefore, […]

Trial of magnesia-alumina carbon bricks at the bottom of 75 t ladle

The ladle is one of the necessary production equipment in the steelmaking plant. It has the functions of transporting molten steel, refining outside the furnace, and casting molten steel. Our company’s steelmaking production is not configured with refining, so the function of the ladle is relatively simple. At present, the structural modes of ladle linings […]

Development of High-Life Converter Sliding Slag-Blocking Brick

Abstract: Many large and medium-sized converters in domestic steel plants adopt slide gate plate slag-blocking tapping technology, and the supporting taphole bricks have become one of the factors affecting the development of sliding plate slag-blocking technology. This article analyzes the application of sliding plate slag-blocking taphole bricks, studies the causes of damage, and proposes optimization […]

What are the alkaline refractory bricks? How much magnesium content can be achieved?

In the refractory industry, refractory bricks with MgO as the main component and periclase as the main crystal phase are collectively called alkaline refractory bricks. Alkaline refractory bricks are mainly used in thermal kilns used in cement, glass, ferroalloy and other industries. Taking the glass melting furnace as an example, alkaline refractory bricks are mainly […]

Design and application of five-hole oxygen lance nozzle for 100 t converter

Design and application of five-hole oxygen lance nozzle for 100 t converter Abstract: In view of the problems of poor slag removal effect and serious slag sticking to steel in the oxygen lance in the smelting of low silicon molten iron, a five-hole oxygen lance nozzle was designed and developed based on the theory of […]

Analysis of the causes of damage to alumina-magnesia carbon bricks and magnesia-carbon bricks during use of carbon-containing refractory materials

Analysis of the causes of damage to alumina-magnesia carbon bricks and magnesia-carbon bricks during use of carbon-containing refractory materials Carbon-containing refractory materials Although carbon-containing refractory materials have significant resistance to molten steel erosion, slag resistance, good thermal shock resistance and high temperature flexural strength, the oxidation problem of carbon limits its service life. During use, […]

Performance and requirements of dolomite bricks used in VOD ladle molten pool area

VOD method ladle In recent years, the use of Dolomite Bricks as a raw material for high-quality refractory materials for the lining of external furnace vacuum treatment devices, especially VOD and VAD molten steel treatment equipment, has increased dramatically and can increase the lining life by more than 1 to 2 times. The main cause […]

Two common recycling methods of waste magnesia carbon bricks and their key technical issues and application prospects

Recycling brick making technology of waste magnesia carbon brick refractory materials Steel production requires a large amount of magnesia-carbon bricks, which provides an outlet for the recycling of used magnesia-carbon refractory materials. Therefore, the recycling brick-making technology of used magnesia-carbon refractory materials has become the focus of development for domestic and foreign steel mills and […]
