摘要： An immersion nozzle is employed for discharging material from a vessel to a mold and includes an upper section to be connected to the vessel and a lower section having a region to be immersed in material in the mold. The upper and lower sections have extending therethrough respective discharge channels that communicate and that enable material to be discharged from the vessel to the mold. The discharge channel of the upper section converges downwardly in a first vertical plane to join the discharge channel of the lower section. The discharge channel of the upper section also expands downwardly in a second vertical plane transverse to the first vertical plane to join the discharge channel of the lower section. Each of the upper and lower sections is formed by at least one respective separate member. The members have adjacent ends having mutually facing and fitting surfaces, and each pair of facing and fitting end surfaces has therebetween a seal.

摘要： A refractory ceramic stopper has therein a recess including an annular outwardly enlarged portion defining a stop surface. A stopper rod inserted into the recess in the stopper has a support surface. A plurality of spreadable members having opposite ends are positioned about the stopper rod and are inserted therewith into the recess in the stopper. The spreadable members are spread outwardly such that they enter the enlarged portion of the recess in the stopper with first ends of the spreadable members confronting the stop surface of the stopper and with second ends of the spreadable members confronting the support surface of the stopper rod. Thereby the spreadable members lock the stopper onto the stopper rod.

摘要： Iron ore pellets on a grid in a treatment chamber are hardened by contact with a heat treated, low calorific gas. The gas is generated in the gasification chamber of a slag bath generator. The generator receives a gasification agent and solid fuel that preferably further includes sulfur-binding materials, such as dolomite for generating a stream of low calorific gas. Inclined water-cooled pipes at the upper end of the slag bath generator extract liquid slag from the gas stream. The slag drips from the pipes into the slag bath generator. A mixing chamber receives the gas at a temperature of about 1450.degree. C passed beyond the inclined water-cooled pipes together with an air supply for heat treating the gas to a temperature of about 1100.degree. C. The heat treated gas is then passed into the treatment chamber for hardening the iron ore pellets contained therein.

摘要： A control system maintains a predetermined volumetric ratio between fine-particle fuel and a gasification agent which are fed separately into a reactor wherein the fuel is gasified under pressure. The control system includes a first measuring means responsive to the absorption of electromagnetic radiation by the fine-particle fuel in a fuel-feed line for producing a fuel-feed signal corresponding to the volumetric amount of fuel conducted by the line. A vehicle gas-feed signal is produced by a second measuring means in response to the volumetric amount of vehicle gas conducted by a line into the fuel-feed line for admixture with the fuel therein. Computing means is responsive to the fuel-feed signal and the vehicle gas-feed signal to produce a control signal according the expression:U.sub.1 . (U.sub.2 - U.sub.v)for all values of U.sub.2 greater than U.sub.v where U.sub.1 corresponds to the reciprocal of the fuel-feed signal, U.sub.2 corresponds to the vehicle gas-feed signal and U.sub.v is a predetermined comparison signal constant. Control valves respond to the control signal to vary the volumetric amount of fuel and gasification agent introduced into the reactor.

摘要： Fine-grain fuel is carbonized at a low temperature by feeding the fuel from a hopper downwardly into the gap formed between two vertically-arranged, plate-type conveyors. The plates of each conveyor move downwardly while their back face surfaces bear against the wall of a heating chamber. The position of the heating chambers is controlled to maintain a narrow gap, e.g., 10-30 millimeters between the plates of the conveyors. The conveyors and heating chambers are located within a container wherein a pressure of up to 100 bars is maintained and a clear gas is passed countercurrently to the downward advancement of the fuel in the gap between the conveyors. Breaker rollers below the conveyors subdivide the carbonized fuel issuing from the gap for passage into a gasification chamber. Part of the gas yield is used as fuel for the heating chambers.

摘要： Liquid slag passes from an overflow in a pressure vessel into an underlying collecting vessel where the liquid slag is transformed into solid granular material by quenching in a liquid coolant. A desired coolant level is maintained within the collecting vessel by control valves under a pressure above atmospheric pressure. Two slide valves in the bottom of the collecting vessel are opened to discharge the granular material after accumulating to a predetermined measured level which is below the liquid coolant in the collecting vessel. A discharge vessel, beneath the collecting vessel, receives the discharged granular material. The discharge vessel is filled with a liquid coolant under either atmospheric pressure or under the same elevated pressure as the pressure within the collecting vessel. When the pressure in the discharge vessel is at atmospheric pressure, two slide valves in the bottom of the discharge vessel are opened to discharge the solid granular material into an underlying container which includes a scraper conveyor to transport the solid granular material.
