After building of a new refractory-lined industrial furnace or equipment, or refractory maintenance or relining of existing equipment, a necessary step is the start-up of the operation, which usually involves heating-up the unit in a controllable way, in order to prevent spalling or shortening of the materials' predicted lifetime.
Fondu Fyre, sometimes called Fondue Fyre, is a refractory concrete developed for specialist application. Fondu Fyre is a heat and erosion resistant concrete developed during the Apollo space program. It was developed to withstand the supersonic plume of a rocket engine during launch and hot-fire tests [citation needed].
Concrete pipes for sewerage can be made either with full mass calcium aluminate cement concrete or with an internal liner of calcium aluminate cement mortar. Rehabilitation of man-accessible sewer infrastructures with 100% calcium aluminate mortar using one of the following placing methods: low pressure wet spray, spinning head wet spray, or ...
Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]
Cement plant clinker dust is more abrasive than sand. In high temperature ducts, or ducts with wear potential, 2 + 1 ⁄ 2-inch refractory, is often anchored to the duct plate with V anchors at 6" O.C. (+/-) to resist a) temperature, or b) wear at elbows or a combination of these effects. Occasionally ceramic tiles or ceramic mortars are ...
The purpose of the refractory lining is to insulate the steel shell from the high temperatures inside the kiln, and to protect it from the corrosive properties of the process material. It may consist of refractory bricks or cast refractory concrete, or may be absent in zones of the kiln that are below approximately 250 °C (482 °F).
Ketton Cement Works is a large cement plant and quarry based in the village of Ketton in the county of Rutland in the United Kingdom. Now owned by HeidelbergCement, the plant produces around one tenth of the UK's Portland Cement needs. Ketton works employs around 220 people. [citation needed]
Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity ...
