Abstract: A weighing bridge used for weighing of large vehicles. The plate is the part of the weighing bridge onto which the vehicles drive and are parked during the weighing. Apart from the plate, the weighing bridge will also comprise a foundation, weighing cells and other electronic equipment which is necessary for the modern weighing of vehicles, but which together are known in the art. The weighing plate is distinguished in that all exterior surfaces are made from a compact composite material. By not having exterior steel surfaces and also utilising the extremely good durability of the composite material against influences from the environment, this together reduces and in some cases alleviates altogether the need for frequent maintenance works in order to renovate or restore the weighing bridge.

Abstract: A lining for use in a blast furnace preferably for use in furnaces burning bio fuels, e.g. straw or wood chips or wood shavings and the like as well as ovens in power stations where fuel having a biological origin is used includes an interior surface which is in contact with slag particles. The interior surface is clad by elements (3, 4, 12) made by a ceramic or semi-ceramic material and an insulation of a cement based foam material is arranged in one or more layers (17). The foam material is advantageously placed between the interior surface and an exterior load carrying construction which for example can be a steel pillar arranged exterior of the blast furnace. With a lining for blast furnace as describes above the risk of a collapse in the insulating material is avoided at the same time it is avoided that the interior wall deteriorates due to the chemical composition of the slag particles which are present in the bio fuelled oven.
