Section 1: Production Process

The production process of spherical asphalt mainly includes the following steps:


  1. Raw Material Selection: High-quality materials like coal are chosen to ensure the quality meets production standards.
  2. Preprocessing: Inspect and preprocess raw materials, removing impurities and substandard parts.
  3. Heating Dissolution: Add the raw materials to the asphalt dissolution kettle, heat to a molten state, and maintain a certain temperature range.
  4. Spray Cooling: Liquid asphalt is ejected from nozzles under pressure, simultaneously being atomized into fine particles by air, which then naturally cool in the cooling tower to form semi-finished spherical granules.
  5. Screening and Grading: Post-cooling semi-finished products are graded through screening equipment, removing particles that do not meet the particle size requirements, resulting in spherical asphalt products that meet the specifications.

Furthermore, spherical asphalt can be prepared through steps such as heat-shrink polymerization and spray granulation, based on specific production processes and formulas.

II. Performance Features

Spherical asphalt boasts the following performance characteristics:

  1. High Fixed Carbon: A higher fixed carbon content contributes to improved material resistance to high temperatures.
  2. Low Ash Content: Reduced ash content minimizes the impact of impurities on material properties.
  3. High resin content: The high resin content enhances the material's bonding and stability.
  4. Uniform particle size: Sifted and graded to ensure the spherical asphalt has a uniform particle size, meeting various application requirements.

Section 3: Application Fields

Spherical asphalt finds wide application in various fields:


  1. Refractory Materials: As the binder and carbon additive for high-temperature resistant materials such as blast furnace iron trough filling, spray patching, ramming, casting, and不定形耐火材料, enhancing their resistance to high temperatures and erosion.
  2. Metallurgical Industry: As an additive for products like ferroalloys, it improves furnace conditions and promotes reactions.
  3. Electrode Material: Used for manufacturing electrodes, featuring excellent conductivity and high-temperature resistance.
  4. Waterproof and Corrosion-Resistant: Has certain applications in waterproofing and corrosion resistance, enhancing the material's waterproof and anti-corrosive properties.

Four, Points for Selection

When selecting spherical asphalt, please note the following points:

  1. Parameters: Review parameters such as softening point, insoluble matter, ash content, coking value, etc., to ensure compliance with usage requirements.
  2. Product Grade: Choose top-grade or first-class products from authorized manufacturers to ensure stable and reliable quality.
  3. Packaging Specifications: Select an appropriate packaging specification based on actual needs, such as 25kg, 50kg, 100kg, etc.
  4. Price and Value for Money: Compare prices and value for money across different manufacturers and choose products that offer reasonable pricing and superior performance.
