Rongsheng self-baking carbon brick for Sale is a kind of carbon refractory material. Rongsheng blast furnace self-baking carbon bricks use high-temperature calcined anthracite as aggregate, calcined anthracite, and coke mixed powder as fine powder, medium-temperature coal tar as binder, and kneads evenly at a certain temperature. It is made by high-frequency molding and vibration molding. Rongsheng blast furnace self-baking carbon bricks are a product with precise dimensions and specific physical and chemical properties. Self-baking carbon brick has the characteristics of high-temperature resistance, good thermal conductivity, high-temperature strength, strong resistance to slag iron erosion, and low price.

Advantages and Characteristics of Blast Furnace Self-Baking Carbon Bricks

Self-baked carbon bricks have the following characteristics in production and use:

• (1) Simple production process, low investment cost, and easy construction.
• (2) With a regular shape, it can be built into the required furnace lining without precision processing.
• (3) After being baked by the heat of the oven and blast furnace production, it can form a nearly seamless integral furnace lining.
• (4) During the baking process, under the condition of single-sided heating, the volatiles of coal tar pitch produce reverse migration, pyrolytic carbon is generated in the pores of the matrix at the working hot end and fills the pores, making the brick body “self” dense.
• (5) It can absorb the temperature stress generated when the furnace lining is heated, and alleviate the damage of thermal stress to the furnace lining.
• (6) Under the catalytic action of high-temperature slag iron and other media in the furnace, a heterogeneous graphitization transformation is produced. The thermal conductivity and chemical corrosion resistance of the furnace lining are improved, and the 1150℃ molten iron solidification isotherm is migrated into the furnace.

Application Advantages of Self-Baked Carbon Bricks

Due to the characteristics of self-baked carbon bricks and the qualitative changes in the furnace, the stability and durability of the furnace lining are ultimately improved. As a result, self-baking carbon bricks can be widely used in small and medium-sized blast furnaces and achieve good technical and economic results. The use of semi-graphite self-baked carbon bricks in large blast furnaces can reduce the melting index of molten iron, increase thermal conductivity, improve alkali corrosion resistance, enhance oxidation resistance, improve erosion and wear resistance, and reduce residual shrinkage.
