Delta Refractories
Concrete in Vereeniging

The manufacturing process of many items which modern man is using on a daily basis, is somehow dependant on refractories. Refractory materials are heat-resistant materials used in furnaces, boilers, smelters, and other high-temperature structures. All industrial production processes are dynamic with regards to optimisation, implementation of new technologies, and the pressures of environmental demands and legislation. The need to cut production cost and time requires that the refractory products be adapted to meet these changes. Delta Refractories designs custom-made to suit each individual client’s needs. The products will require the least possible addition of water to achieve optimum flow characteristics. The products are categorized according to the maximum temperature, which they can continuously be subjected to without damage to the product or its principal properties. The raw materials on which the individual products are based, determines the important physical properties. Technical data sheets, mixing, installation, curing and pre-heating instructions, as well as material safety and handling documentations, are available upon request. This results in products with exceptionally impressive physical and chemical properties, especially at high temperatures. Some products are supplied as a two-component system, and if prepared according to mixing and installation instructions, products are easy to install, and very forgiving with regards to curing and pre-heating. The products are categorized according to the maximum service temperature, which they continuously can be subjected to without damage to the product or its principal properties. In order to achieve the least amount of temperature loss, the products are generally based on low-density raw materials with high melting temperatures. These products are easy to prepare and install, and very forgiving with regards to curing and pre-heating. The stainless steel needles provide the thermal shock resistance and the ceramic matrix acts as the binder system. The composition of the ceramic matrix and the grade of stainless steel can be adjusted for application. The products are based on a wide range raw materials, and normally supplied ready for use. The products are categorized according to the temperature at which they must coagulate the slag. The products are based on a wide range of raw materials, and normally supplied ready for use. The products are normally manually added as a dry additive to the slag. Technical Data Sheets, mixing, installation, curing and pre-heating instructions, as well as material safety and handling documentations, are available upon request. The products are designed to require the least possible addition of water to achieve optimum handling characteristics. This makes for quick and easy installation of big volumes of castables. In some case, the binder or wetting agent is supplied by the end user and mixed into the material just before installation.
