Dickinson Group Companies and Delta Refractories (Pty) Ltd are pleased to announce the conclusion of an alliance between the two companies. This development will allow for the provision of integrated services to refractory consuming industries across the region. A complete range of custom-made, high performance and cost effective precast refractory shapes that are manufactured using Delta Refractories material will be efficiently extended to various industries.

Delta Refractories was founded in 2001 and has become a leader in reliable, cost effective refractory solutions for a variety of industries. Delta Refractories’ main products include the tried and tested standard monolithic refractory products and refractory bricks. The company also supplies special research-intensive products, tailor made for every industry, client and application. Delta Refractories’ range of products and services can be summarised as follows:

  • Ramming, gunning, plaster, pumpable, mortars and others.

  • Dense and light weight castables (acid and basic)

  • Special monolithics for continuous casting

  • Consultancy services with regards to process development in pyro-metallurgical industries


Dickinson Group of Companies’ Precast Division was established in 1986, specialising in the design, manufacture and installation of customised precast refractories shapes. With world-class production facilities and advanced design capabilities; the company has established itself as a leader in the field, having the capacity to manufacture a wide range of precast shapes for various applications. The revolutionary concept of precast refractory shapes has been well received in different industries. It involves the design, casting and dry-out of complete sections of refractory blocks off-site, under controlled conditions, in purpose-designed production facilities. The precast shapes are manufactured under stringent quality control procedures, ensuring that consistent mixes of the refractory material are casted in highly accurate moulds, dried at suitable temperatures to allow for the formation of a ceramic bond and are properly cured as to achieve enhanced service life. Precast shapes offer the added benefit of ease of installation and shortened repair times and are characterised by the following:

  • Consistent and controlled manufacturing process.

  • Unique purpose developed materials and shapes for each application.

  • Work done off site resulting in minimum interference with production.

  • Areas of higher wear can be engineered with optimal refractory materials.

  • Easier slag or dross removal due to lower porosity.

  • Less down time due to quicker installation and heat-up times are minimized.

  • Shapes from 1 kg to 9 metric tons, resulting in less joints and faster installation.


The range of refractory precast refractory solutions includes the following:

  • Furnace roof-panels;

  • Screw conveyors,

  • Furnace feed-pipes;

  • Blast-furnace combustion stove ceramic burners, elbows, down legs & blowpipes

  • Anode-baking furnace top blocks;

  • Tundishes;

  • Holloware;

  • Burner quarls;

  • Launders, well and seating blocks;

  • Coke-oven roof, regenerator, corbel & flue walls bricks.

  • Cement plants

  • Cooler and bullnose

  • Kiln hood

  • Cyclone roofs

  • Burner pipes

  • Tertiary air duct dampers
