Due to their excellent thermomechanical properties and corrosion resistance against aggressive steel/slag systems, carbon-bonded magnesia (MgO–C), alumina-magnesia (AMC), and magnesia-alumina (MAC) bricks are the dominating refractories for the lining of the side walls and bottom of steel ladles, basic oxygen furnaces, and electric arc furnaces.
During the initial heating of Calcium Aluminate Cement (CAC)-bonded castables, physical and chemically-bonded water is released. Therefore, when the refractory’s permeability level is limited, pressure buildup inside the dense microstructure can take place, resulting in cracks and spalling of the ceramic lining.
Monolithic ladle linings are cost efficient and environmentally friendly because a significant part of the used ladle lining can remain inside the ladle for a long time while only the effectively worn out part needs to be replaced by a repair mix.
One of the most important and very possibly the most urgent issue facing society today, is the preservation of the environment to maintain the quality of all forms of life on the planet.
Continuously from 1850, PCO Zarów designs, produces and supplies refractory solutions that enable to burn, melt, mould or heat safely, allowing its clients to keep the heat under control.
China remains the largest producer of refractories, and is expected to account for more than two thirds of a global output of 37,3 Mt in 2019.
As part of its growing portfolio of specially designed products for foundry, casting and heat treatment, IPS Ceramics is now supplying ceramic casting plugs in a range of sizes, shapes and materials.
In Vietnam, the demand for products such as cement, glass or chemical fertilizers is constantly growing. The demand for energy, covered by oil and coal, is also rising. In many production processes, there are process stages that run at high temperatures.
Tenova/IT – a company of the Techint Group specialized in innovative solutions for the metals and mining industries – has concluded the selling process of the HTC Group, which includes four companies – IVA Schmetz/DE, Mahler/DE, Fours Industriels B.M.I./FR and IVA Schmetz Industrial Furnaces/CN – specialized in advanced technologies for heat treatment processes for components.
For ten years, Prof. Dr Peter Quirmbach was Managing Director of ECREF – European Centre for Refractories gGmbH in Höhr-Grenzhausen. In mid-April, he handed over the management to Dr Christian Dannert and Andreas Hermann.
