A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.

A method for protecting an inner wall (12) of a shaft furnace, the method comprising the steps of: providing at least one injection device (28) through the inner wall (12) of the shaft furnace, the injection device (28) being configured to inject protective material into the shaft furnace; and injecting on demand the protective material into the shaft furnace through the injection device (28), in such a manner that the protective material builds up to form a protection wall between the interior of the shaft furnace and the furnace wall (12).

A refractory spraying robot in iron steel production plants, detecting the worn areas of the units such as arc furnace, induction furnace, converter, ladles and other similar units, due to fluid steel effects, by a measurement instrument, processing the obtained data by PLC and mapping the worn faulty sections automatically, transferring the discovered coordinates to a spraying head and performing fully automatic repair work by spraying refractory materials onto the faulty sections without human touch.

Method for determining the state of a fire-resistant lining of a vessel containing molten metal in particular in which maintenance data, production data, and wall thicknesses at least at locations with the highest degree of wear are measured or ascertained together with additional process parameters of at least one identical/similar vessel after the vessel has been used. The data is collected and stored in a data structure. A calculating model is generated from at least some of the measured or ascertained data or parameters, and the data or parameters are evaluated using the calculating model using calculations and subsequent analyses. Thus, related or integral ascertaining processes and subsequent analyses can be carried out, on the basis of which optimizations relating to both the vessel lining as well as the complete process of the molten metal in the vessel are achieved.

A method for repairing a refractory lining of a metallurgical vessel in the hot state. This repair takes place using a supplying apparatus. In addition, recording of at least the worn regions and monitoring of the repair are carried out by a monitoring device. Before, during and/or after the supplying of material, at least a partial region of the areas of the refractory lining of the vessel or the gunning jet is recorded photographically with visualization of the temperature ranges. This results in an evaluation with regard to different parameters such as properties, layer thickness and/or distribution of the supplied material. It has been demonstrated that visualization of the temperature ranges of the areas to be repaired and of the refractory material during supplying of material enables different parameters to be established very accurately, and as a result, optimal coating of the wall lining can be achieved.

A method relates in particular to the repair of a refractory lining of a metallurgical vessel (10) in the hot state. This repair takes place here by means of an supplying apparatus (15). In addition, recording of at least the worn regions and monitoring of the repair are carried out by means of a device (20). Before, during and/or after the supplying of at least a partial region of the areas (13) of the refractory lining (12) of the vessel (10) to be repaired or the gunning jet (18) is recorded photographically here with visualisation of the temperature ranges (26, 27, 28), and this results in an evaluation with regard to different parameters such as properties, layer thickness and/or distribution of the supplied material. It has been demonstrated that by means of this visualisation of the temperature ranges of the areas to be repaired and of the refractory material during supplying different parameters can be established very accurately, and as a result optimal coating of the wall lining can be achieved.
