REFRACTEC ENGINEERING PRIVATE LIMITED 
Precision Castable Lining for High-Heat Applications
Refractec Engineering Private Limited offers specialized castable lining by casting solutions for high-temperature industrial applications where conventional brickwork is either impractical or inefficient. Designed for complex geometries and large surface areas, castable linings offer superior performance in resistance to heat, abrasion, and corrosion, making them the go-to choice for a variety of industries including steel, cement, power, and petrochemical.
Castable refractory materials are highly suitable for areas where shaped bricks cannot be easily installed due to curves, intricate designs, or limited accessibility. Whether it’s a combustion chamber, cyclone separator, burner pipe, or duct, castable linings fill the void seamlessly, hardening in place to form a dense, monolithic structure that can withstand thermal shocks and aggressive chemical environments.
Precision Casting for Uniform Strength
We employ formwork casting techniques using high-quality molds that align perfectly with the geometry of your equipment. Our team ensures that the refractory mix is poured with consistent flowability, proper compaction, and zero voids. This results in an even density across the entire lining, minimizing weak points and increasing structural longevity. Our field engineers oversee every phase of the casting—from mold preparation to curing—ensuring a flawless execution.
High-Performance Castables Tailored to Application
Depending on your temperature and load conditions, we select from a range of low-cement, ultra-low cement, insulating, or dense castables. Each type is chosen to meet the mechanical, chemical, and thermal demands of your system. Whether you’re lining a waste heat recovery unit or a secondary combustion zone, we tailor the material properties to ensure optimal heat resistance, mechanical strength, and ease of maintenance.
Engineering Precision Meets On-Site Expertise
What sets Refractec Engineering Private Limited apart is our ability to combine engineering precision with hands-on expertise. We create detailed lining plans, thermal stress analysis, and installation procedures tailored to your equipment. All site work is executed by our trained refractory technicians under strict supervision, following global safety and quality standards.
Castable linings deliver strength, flexibility, and thermal efficiency where brickwork cannot be used effectively.
We utilize different castable formulations—dense, medium-weight, and insulating—based on the thermal and mechanical stress zones. Each type is carefully mixed and applied to achieve uniform density and strength, optimizing performance throughout the system while reducing material wastage.
From formulation to application, our castable lining by casting ensures flawless coverage, optimal strength, and durability—making it the ideal choice for static structures and heavy-duty thermal operations.
