Problems solved by technology
Another conventional method is that the hot bending pipe is arranged vertically on the moving trolley, and the moving trolley moves parallel to the connection line between the two processing stations. Two sets of pipelines are also required, and two sets of pipeline valves are also required correspondingly, or a combination of one set of valves and a moving pipe bending trolley is used. The investment and floor space of this method are still large. Due to the shortage of land resources, more and more The factory requires the equipment to occupy a small area. The problem of how to realize the process requirements in the effective area, save investment, and complete the work process reliably will be solved by the method of hot bending pipe moving process layout.

The invention relates to a moving device and a moving method of hot elbow pipes of a RH (Relative Humidity) refining furnace. The device at least comprises a first vacuum treatment slot, a vacuum air-pumping pipeline and a second vacuum treatment slot, wherein the vacuum air-pumping pipeline is arranged between the first vacuum treatment slot and the second vacuum treatment slot; the hot elbow pipes are connected between the vacuum air-pumping pipeline and the first vacuum treatment slot or between the vacuum air-pumping pipeline and the second vacuum treatment slot; the hot elbow pipes are positioned on a travelling car in parallel; and the hot elbow pipes are dynamically connected in a switching manner between the vacuum air-pumping pipeline and the first vacuum treatment slot or between the vacuum air-pumping pipeline and the second vacuum treatment slot under the centralized control of a driving device, a variable frequency motor and a braking mechanism. As the device is used, the investment is reduced; the production rate is expedited; the equipment assemblies are reduced; the reliability is improved; and the external refining equipment of the double-station RH furnace can be placed in a small space.
Description
technical field [0001] The invention belongs to a hot bending tube moving process arrangement method of an RH vacuum refining system, in particular to a hot bending tube moving device and method for an RH refining furnace. Background technique [0002] When the RH vacuum refining system performs double-station processing, one of the conventional methods is to switch the processing position with the vacuum tank mobile trolley. The hot bending pipe is fixed on the vacuum tank and travels with the tank mobile trolley, which makes The load of the car increases, and the hot bending pipe must have two sets of fixed devices. This method also requires two relatively large driving trolleys, which are large in size and heavy in weight. They require a lot of auxiliary equipment and occupy a large area. At the same time, the time for each car to move is relatively long. Another conventional method is that the hot bending pipe is arranged vertically on the moving trolley, and the moving...
