Removal of burrs by high-pressure fluid jet and appropriate industrial device In compliance with this invention, burrs are removed from machined part (44) by high-pressure fluid jet and high rate forced from high-pressure jet nozzle (30) connected with high-pressure fluid circuit (32). Intake tank (16) for removal burrs includes filling inlet (48) connected with high-pressure fluid circuit for filling of said intake tank (16) and including cleaning fluid bath (46) used in operation. Prior to burrs removal said intake tank (16) is filled with cleaning fluid via filling inlet (48). Then, burrs are removed from machined part (44) by fluid jet without gas shell at dipping both said high-pressure high-rate fluid jet and machined part into bath with cleaning fluid. |

Invention pertains to coke furnace operation method. According to the method coke gas generated in coking process is supplied as useful gas to processing of raw materials, at that hydrogen is separated from coke gas, and in order to generate thermal energy required for coking process synthetic gas is supplied as combustion gas, which is produced from fossil fuel by gasification process, at that the first share of the obtained synthetic gas is used as combustion gas, at that extra share of the obtained synthetic gas is used for further synthesis with hydrogen separated from coke gas. |
