World leader for refractory products and solutions RHI Magnesita announced that a new tunnel kiln was fired up at the Urmitz plant in Germany last month. The 122 meter long lightweight kiln generates temperatures of up to 1550 degree Celsius and represents the heart of modern refractory production. It is primarily used to fire bricks for the refractory lining of aggregates, which are essential for the steel, glass, cement, lime, energy and chemical industries. This is the first time in decades that a tunnel kiln for shaped and fired refractory products has existed at the Urmitz plant. The tunnel kiln will burn continuously for several decades and its performance will increase the plant’s capacity by around 25,000 tons per year. The new tunnel kiln significantly expands the plant’s product range and serves to further enhance offerings in non-basic refractory products.RHI Magnesita has invested a total of 23 million euros in the site. This will re-equip and expand the traditional plant as a central European hub for the manufacture of non-basic refractory products. In addition to the costs for the construction of the tunnel kiln, the investment is accompanied by the modernization, automation and all-encompassing digitalization of the plant, which are decisive factors for the optimization of the value chain. This will grow the plant’s production volume and at the same time increase its energy efficiency by 10 percent.
