New Launch: CR05F 25L Intensive Laboratory Mixer with Heating System for Continuous Casting Refractory R&D
Description: The CR05F 25L Intensive Laboratory Mixer is a dedicated temperature-controlled testing machine for continuous casting refractory three major components, supporting standard 30℃ dry powder mixing and 60℃ wet granulation process for stopper rod, long nozzle and SEN refractory R&D.
1. Product Introduction
The CR05F 25L Intensive Laboratory Mixer with Heating System is a newly upgraded professional testing equipment exclusively designed for continuous casting refractory research, formula verification and small-batch trial production. It targets the three core metallurgical refractory components: stopper rod, long nozzle (shroud), and submerged entry nozzle (SEN). Different from ordinary laboratory mixers, this intensive mixer supports full-cycle temperature-controlled mixing and granulation. It effectively solves common industry pain points including uncontrollable temperature rise, uneven material mixing, and poor experimental repeatability in alumina-carbon and alumina-zirconia-carbon refractory testing.
2. Industry Challenges in Refractory Lab Testing
The performance stability of continuous casting refractories largely depends on accurate temperature control and homogeneous raw material mixing during laboratory experiments. Traditional lab mixing equipment cannot match the spontaneous exothermic reaction characteristics of refractory powders. Uncontrolled temperature fluctuation during mixing easily causes inconsistent material reaction degree, unstable bulk density and porosity, and deviated test data. These problems greatly restrict the formula iteration and performance upgrading of high-quality stopper rods, long nozzles and SEN refractory products for steel continuous casting.
3. Standard Full-Cycle Temperature Control Process
The core advantage of the CR05F 25L Intensive Laboratory Mixer is its standardized full-temperature experimental cycle, which perfectly simulates the actual production reaction state of continuous casting refractories:
- Dry Powder Mixing Stage: Maintain constant internal temperature at 30℃, continuous mixing for 5 to 8 minutes. Ensure full uniform premixing of refractory raw materials without premature chemical reaction.
- Wet Mixing & Granulation Stage: Cooperate with material self-heating reaction, stably raise the material temperature to 60℃ within 20 minutes of wet mixing and granulation, realizing consistent and controllable material reaction.
This standardized process eliminates temperature deviation errors, ensuring laboratory test data is highly consistent with formal industrial production parameters.

4. Intensive Mixing Performance Advantages
Equipped with a 3D dead-angle-free intensive mixing structure and frequency conversion stepless speed regulation system, the CR05F 25L laboratory mixer realizes homogeneous integration of refractory powder, binders and auxiliary additives. The optimized mixing technology effectively reduces material internal porosity, improves finished product bulk density and high-temperature thermal stability. It provides stable, repeatable experimental data for formula optimization of stopper rods, long nozzles and SEN refractories, greatly improving the efficiency of refractory R&D and debugging.
5. Safety & Structural Configuration
All material contact surfaces adopt high-temperature resistant and corrosion-resistant stainless steel, which effectively avoids cross-contamination of precision refractory formulas and supports rapid cleaning and frequent batch switching.
Built-in over-temperature protection and power-off safety protection devices fully comply with international laboratory safety operation specifications. The equipment features low energy consumption and long service life, fully meeting the daily R&D, small-batch trial production and process verification needs of refractory manufacturers and metallurgical research institutions.
6. Application & Industry Value
With the continuous upgrading of high-standard continuous casting refractory demand in the steel metallurgy industry, standardized temperature-controlled laboratory mixing equipment has become a key guarantee for refractory product quality improvement.
As a professional dedicated mixer for continuous casting refractory three major components, the CR05F 25L Intensive Laboratory Mixer fills the market gap of targeted temperature-controlled refractory testing equipment. It standardizes the full-cycle mixing and granulation process of alumina-carbon and alumina-zirconia-carbon materials, shortens the formula R&D iteration cycle, and provides reliable technical support for the mass production of high-performance metallurgical refractories.
