Description

TECHNICAL FIELD

[0001] The utility model belongs to tar processing technical field, concretely relates to a tar automatic modification treatment device for anhydrous stemming. BACKGROUND

[0002] In the process of blast furnace ironmaking, stemming is an important refractory material for plugging the tapping hole, and its performance is directly related to the safe operation and smooth efficiency of the blast furnace. In recent years, anhydrous stemming has gradually replaced water stemming due to its excellent performance and has become the mainstream refractory material for blast furnace smelting. Among them, tar as the main binder of anhydrous stemming plays a crucial role in the plasticity, workability and stability of the blast furnace. However, there are still many problems in the use of existing tar materials, which seriously affect the final quality of the stemming.

[0003] Firstly, the quality of tar fluctuates greatly, and the carbon content is low, which leads to insufficient strength of the stemming after high-temperature sintering, easy to produce cracks or peeling, affecting the sealing of the tapping hole. In addition, the coking ability of tar is poor, and it cannot form a stable carbon skeleton in high-temperature environment, further reducing the wear resistance and erosion resistance of the stemming.

[0004] Secondly, the viscosity of tar is low, which easily leads to insufficient bonding force between particles during the stemming batching process, making the plasticity of the stemming decrease and affecting the stability of the construction. At the same time, the moisture content of tar is high, which is easy to form bubbles or holes during the stemming forming process, reducing the density and compactness of the stemming, thereby affecting its service life and stability. In addition, the volatile content in tar is high, which is easy to release harmful gases under high-temperature conditions, not only polluting the environment, but also possibly threatening the health of blast furnace operators.

[0005] In addition, due to the great influence of temperature on the specific gravity and viscosity of tar, stratification and sedimentation phenomena are easy to occur during storage and use, leading to uneven quality of tar and even affecting the overall batching effect of the stemming. At the same time, the accumulation of tar residue also increases the maintenance cost of the equipment and reduces the production efficiency. INVENTION CONTENTS
