About Oniir Marketings
Oniir Marketings is a leading manufacturer and supplier specializing in high-performance refractory materials. With years of experience in the industrial supply sector, the company has built a strong reputation for reliability, technical expertise, and customer satisfaction. Oniir serves industries across Punjab, providing high-quality refractory castables that meet demanding industrial standards.What Are Refractory Castables?
Refractory castables are specialized heat-resistant materials composed of refractory aggregates, binders, and additives. They are supplied in dry, granular form and become hard when mixed with water, forming a strong monolithic lining capable of withstanding extreme heat. These castables are widely used in furnaces, boilers, kilns, and reactors due to their ability to resist thermal shock, corrosion, and mechanical wear.1. Maxheat-K (also known as Whytheat-K)
Maxheat-K, popularly known as Whytheat-K, is a high-quality high-alumina refractory castable designed for superior heat resistance and mechanical strength. Manufactured by Oniir Marketings, this castable is suitable for use in furnaces, kilns, and boilers where temperatures can exceed 1600°C.2. Maxheat-A (also known as Whytheat-A)
Maxheat-A (Whytheat-A equivalent) is a general-purpose refractory castable with excellent strength and durability at medium to high temperatures. It offers strong adhesion and long service life, making it ideal for industrial furnaces and ovens.3. Maxcrete Super (Equivalent to Firecrete Super)
Maxcrete Super, equivalent to Firecrete Super, is a high-strength refractory castable designed for high-performance furnace linings. It provides excellent resistance against chemical attack and thermal wear.4. Maxcrete-LT (Equivalent to Firecrete-LT)
Maxcrete-LT or Firecrete-LT equivalent is a low-temperature refractory castable known for its thermal stability and insulation properties. It offers good volume stability and is easy to apply for light-duty applications.5. Calcium Aluminate Cement Binder
Calcium Aluminate Cement (CAC) is a premium binding material used in manufacturing refractory castables and monolithic linings. It provides high early strength, low porosity, and excellent resistance to thermal and chemical attacks.Importance of Refractory Castables in Industries
In industries where temperatures exceed 1000°C, conventional materials simply can’t withstand the stress. That’s where refractory castables come in. They provide superior thermal insulation, protect steel structures, and improve energy efficiency — making them essential for steel plants, cement industries, foundries, and power plants.Types of Refractory Castables
1. Low Cement Castables (LCC)
LCCs have low calcium oxide content, offering improved mechanical strength and higher temperature resistance.2. Ultra Low Cement Castables (ULCC)
ULCCs contain even lower cement, providing high density and resistance against slag and corrosion.3. No Cement Castables (NCC)
Ideal for high-temperature furnaces, NCCs use advanced binders instead of cement, ensuring outstanding strength and durability.4. Insulating Castables
Lightweight and porous, insulating castables reduce heat loss, enhancing energy efficiency in furnaces and boilers.5. Conventional Castables
These are economical, easy to apply, and suitable for general-purpose applications.6. High Alumina Castables
Containing high alumina content, these castables offer superior strength, abrasion resistance, and stability at extreme temperatures.Technical Specifications of Refractory Castables
