Introduction
In the world of coal and coke testing, understanding the plastic properties of coal is vital to predicting its coking behavior and performance in industrial furnaces. The Plastometer PF-12 is a state-of-the-art instrument designed to determine the plasticity characteristics of coal, a key factor in assessing its suitability for metallurgical coke production.
For laboratories and industries that demand accurate and repeatable results, the PF-12 stands as a reliable, efficient, and precise testing solution. It simplifies the process of determining plastic range, softening temperature, and resolidification points — parameters that directly influence coke strength and yield.
What Is a Plastometer?
A plastometer is a specialized coal testing instrument that measures the plastic properties of coal as it undergoes heating. When coal is heated under controlled conditions, it softens, becomes plastic, and eventually resolidifies. This behavior is critical in determining the coal’s coking potential — that is, how well it can form a strong, porous coke structure required for blast furnace operations.
The Plastometer PF-12 specifically measures the plastometric index (Y-value) and softening temperature range, offering valuable data for coal blend optimization and quality control in the steel and metallurgical industries.

Applications of the Plastometer PF-12
The Plastometer PF-12 plays a crucial role in several industries and laboratory environments, particularly those involved in coal and coke quality analysis.
Here are some key applications:
1. Metallurgical Industry
In coke-making operations, the PF-12 helps identify coals with optimal plasticity for producing strong metallurgical coke. It assists in blending coals with complementary characteristics to achieve desired coke quality.
2. Coal Research Laboratories
For researchers studying coal behavior, the PF-12 provides detailed data on softening, plastic, and resolidification stages. This information is vital for developing new methods to enhance coal utilization efficiency.
3. Steel and Iron Production
By determining coal’s coking properties, the PF-12 helps steel manufacturers ensure consistent furnace performance, fuel efficiency, and product quality.
4. Quality Control Facilities
Routine testing of incoming coal batches ensures that only coals meeting the required plasticity standards are used in coke production, minimizing waste and optimizing yield.
Understanding Coal Plasticity and Why It Matters
When coal is heated in the absence of air, it undergoes thermal decomposition. During this process, it passes through a plastic stage before resolidifying into coke. The extent and duration of this plastic phase determine how well the coal particles fuse and form a strong coke structure.
Poor plasticity can lead to weak, crumbly coke — unsuitable for blast furnaces. On the other hand, optimal plasticity ensures uniform fusion, high strength, and better gas permeability in the furnace.
The Plastometer PF-12 allows scientists and engineers to quantify this behavior, making it easier to predict coal performance and adjust blends to achieve ideal coke strength.
Why Choose the Plastometer PF-12?
The PF-12 isn’t just another lab instrument — it’s a complete coal testing solution designed with precision and user efficiency in mind. Here’s why laboratories prefer it:
- Accuracy You Can Trust: High-sensitivity measurement ensures precise determination of coal softening and plastic ranges.
- Automation for Reliability: Automated heating, data capture, and analysis reduce operator error and ensure consistency.
- Versatility: Suitable for all types of coal used in metallurgical, energy, and research applications.
