Product Description

Good Oxidation Resistance Magnesia Carbon Refractory Brick for Ladle

Magnesia carbon bricks are made of magnesia sand, dead-burned magnesia sand, fused magnesia sand, high-purity magnesia sand, high-quality graphite and bauxite additives. The performance of alumina-magnesia carbon bricks is closely related to the graphite content in the bricks. As the graphite content increases, the strength of the brick decreases, the thermal expansion rate decreases, and the residual expansion rate increases. Refractory MgO-C bricks are very suitable for the requirements of steel smelting. This brick has the characteristics of high refractory, high corrosion resistance, excellent heat resistance, high temperature anti-flaking stability, and high thermal shock resistance, and has been rapidly promoted and applied. Using carbon materials that are difficult to be wetted by slag and molten steel, and using the high refractory properties, high slag resistance and solubility, and low high temperature creep of magnesia sand, MgO-C (magnesia carbon) bricks are used in places with severe corrosion, slag lines and products, steel mouths and other parts. Due to the extensive use of magnesia carbon bricks in the steelmaking process and the improvement of steel smelting technology, huge economic benefits have been created. The graphite content in the brick should be controlled at about 20%. Magnesium carbon bricks have low wettability on slag and are suitable for the ladle slag line part, especially for occasions of continuous casting of multiple furnaces. In order to meet the needs of producing clean steel, the application of magnesia carbon bricks in the ladle refining process has been expanded from the slag line to the side wall. In the ladle, the chemical composition of the slag is complex and changeable, and the temperature changes violently and frequently. The ladle slag line often uses high-performance ladle magnesia carbon bricks. Electric furnace magnesia carbon bricks are mainly used for the lining and tapping of the medium-frequency electric furnace steelmaking oxidation converter, the hot spots of the high-power electric furnace wall, the lining of the external refining furnace, the slag line of the ladle, etc.

Good Oxidation Resistance Magnesia Carbon Refractory Brick for Ladle
Magnesia carbon brick production process 1.Selection of raw materials The raw materials for the production of MgO-C bricks are mainly magnesia. The technical requirements are high purity, few impurities, complete particle crystal development, uniform texture, low porosity and high volume density. Magnesia is divided into fused magnesia and sintered magnesia, but gradually replacing part of the sintered magnesia with fused magnesia can significantly improve the corrosion resistance. The carbon raw material generally uses natural flake graphite. It has no eutectic relationship with oxides such as MgO and does not form low-melting materials. It has high thermal conductivity, small elastic modulus, low thermal expansion coefficient, and is non-wetting. Binder is the key material for the production of MgO-C bricks. Its technical requirements: (1) The wetting angle for carbon materials is small and the affinity is good; (2) The residual carbon rate is high; (3) The impurities and moisture content are low. Commonly used binding agents include phenolic resin, modified phenolic resin and tar asphalt. Nowadays, most MgO-C bricks are produced using synthetic phenolic resin. Admixtures mainly include unit metals and multi-element metal powders such as Al, Mg, Si, Al-Mg, Al-Si, Al-Mg-Ca, carbon pure substances and complex alkalized substances such as B4C, Al8BC7, Al4SiC4, ZrB₂, MgB, CaB6 and other borides. 2.Proportion 5-1(3-1)mm magnesia 50~60%, <1mm magnesia 10%, <0.074mm magnesia + graphite + additives 30~40%, resin 5% (extra). 3. Practice The feeding sequence is generally magnesia particles - binder - graphite - magnesia fine powder and mixed fine powder of additives. And it is best to do it in a kneading equipment with a heating device, so that the resin has good flow properties and can achieve uniform distribution. 4. Forming When using a hydraulic press to produce MgO-C bricks, the pressure is generally required to reach 115~200MPa. The number of pressurization times cannot be less than 15 times. 5.Heat treatment MgO-C bricks are generally processed at a temperature of 200~250℃. The heating system is: 50~60℃, because the resin softens, it should be kept warm; 100~110℃, a large amount of solvent is discharged, so it should be kept warm; 200 or 250℃, in order to make the reaction Completely, should be kept warm. It is not difficult to see that the production of MgO-C bricks from raw materials to processes has reached its limit. Therefore, the improvement of the performance of existing MgO-C bricks will be slow and very limited. In addition, resources are limited. Since graphite is easily oxidized, the high-temperature reaction between magnesium chloride and graphite always exists, especially in a vacuum metallurgical environment. The redox reaction of MgO-C bricks and the redox reaction of oxide inclusions and carbon are determined by the nature of the material. The ease of oxidation of graphite is the dominant aspect that determines this nature. Therefore, artificial modification of graphite is an effective way to solve this problem. Only in this way can the chemical compatibility conditions of MgO-C bricks be further improved, thereby promoting the development of MgO-C bricks.
