GRABE Metallkonstruktion in Herne
GRABE defines a chute as being a charging channel or a similar filling device which distributes the burden in the blast furnace in a targeted manner.
Depending on the burden throughput, which amounts to approx. 11 million tonnes per chute, the chute will have to be replaced sooner or later, in order to ensure a continuous blast furnace process. The chute normally comprises a number of wearing plates which are joined together. A prevention or deceleration of mechanical wear being caused by the material is achieved by installing the following:
