Pitch coke is a solid residue obtained from coal tar pitch after high-temperature dry distillation or delayed coking. It is a low-sulfur, low-ash coke. It is a product obtained by direct coking of coal pitch (medium temperature pitch or hard pitch) as raw material in a coke oven. It can also be produced by delayed coking method, and the final coking temperature is above 1100°C. Pitch coke is the raw material of electrode material for aluminum smelting in the electrochemical industry. Generally, the pitch coke and coal pitch are bonded into a block of 20 kg to 30 kg as an electrode substrate. In addition, pitch coke is also used to produce high-grade cast iron, such as ductile iron.
Uses of pitch coke
If the amount is the most, it should be paving asphalt pavement (generally choose heavy handed 90# 70# and modified asphalt). As asphalt has good adhesion, insulation, heat insulation and moisture-proof, anti-seepage, waterproof, anti-corrosion, anti-rust and other properties, it has a wide range of uses in addition to paving.
1. When building a shelter, asphalt is often used as a waterproof layer, and when a refrigerator is built, asphalt and wood chips are often mixed to form an insulating layer;
2. Coating asphalt on railway sleepers can prevent corrosion; coating underground pipes with asphalt can prevent rusting;
3. The reservoir dam is covered with a layer of asphalt to prevent seepage and leakage;
4. The injection of asphalt into the joint of the bridge deck can play the role of thermal expansion and contraction.
5. Asphalt can also be mixed with other materials to make asphalt paint, asphalt felt, asphalt rubber, asphalt coating, asphalt insulating adhesive and other products.
With the development of modern science and technology, the use of petroleum asphalt is also more extensive. In terms of building materials, mixing asphalt and soil can make asphalt bricks and asphalt slabs with high strength, low water absorption, beautiful and durable appearance, which is a new type of building material. In agriculture, mixing asphalt and fertilizers and then spraying them on the soil surface can keep warm, reduce water evaporation, and prevent fertilizer loss. In the electrical industry, asphalt can be used as insulating material and cable protection layer, especially underground cables and underwater cables are inseparable from asphalt. In addition, if the asphalt is further processed, petroleum coke necessary for the steelmaking industry can be obtained, and carbon fibers necessary for the manufacture of spacecraft can also be provided. It can be seen that asphalt has a wide range of uses, and it can be called an unknown hero in the transformation and conquest of nature by human beings.
