Embodiment Construction
[0024] Combine below figure 1 Specific embodiments of the present invention will be described.
[0025] The installation method of the converter vaporization cooling flue during maintenance, the method includes the following steps:
[0026] a. Set the sliding bracket 3
[0027] Install the track 4 at the hoisting position of the flue body 5 in front of the furnace, and install the sliding bracket 3 on the track 4. The track 4 is laid towards the center of the converter 6. The sliding bracket 3 can slide towards the converter 6 and is installed on the same level. The hoist 2 performs traction control on the sliding bracket 3 .
[0028] b. Install hoops and protective steel plates 7
[0029] Select a reasonable hoisting point for the flue body, install the hoops prefabricated in advance according to the hoisting angle of the flue body on the flue body, and install the upper hoop 8 and the lower hoop 9 on the pipeline in the upper half of the flue body, and the upper hoop 8 a...

The invention relates to an installation method of a converter vaporization cooling flue during overhauling. The installation method of the converter vaporization cooling flue during overhauling comprises the following steps of a, arranging a sliding bracket: installing the sliding bracket and a winch for carrying out traction control on the sliding bracket; b, installing a hoisting hoop and a protection steel plate: installing the hoisting hoop and the protection steel plate on a flue body, wherein the welding positions are reinforcing rings and other non-pressurized parts; c, hoisting the flue to the vertical hoisting position: using an overhauling joist barrow for upwards hoisting the flue body to run, using a converter for cooperatively pushing the flue body, sliding the sliding bracket to the center of the converter, using a truck crane for cooperatively hoisting and pushing upwards, and feeding the flue body into the flue vertical hoisting position; d, vertically hoisting the flue: using the overhauling joist barrow for vertically hoisting the flue body to the predetermined height, and using a manual chain block for adjusting the flue body to the predetermined position and the predetermined angle; and e, fixing the flue: after adjusting the flue body, fixing the flue body, disassembling the hoisting hoop and the protection steel plate, and finishing installing the flue. According to the installation method of the converter vaporization cooling flue during overhauling provided by the invention, the loss during overhauling can be effectively reduced.
Description
technical field [0001] The invention relates to a converter pipeline installation method, in particular to a converter vaporization cooling flue installation method during maintenance. Background technique [0002] The converter steelmaking system of iron and steel enterprises mostly adopts more than one parallel system, and the multiple converter systems are generally not completely independent, and there are some intersecting public systems (including medium pipelines and steel structure support systems); , in order to reduce the losses caused by the suspension of production, generally one of the sets of converter systems will be shut down for maintenance, the other sets of converter systems will continue to produce, and the intersecting public system will be temporarily refitted or isolated; the main frame structure of the plant and equipment is not allowed to be dismantled and changed, and the auxiliary frame If the support system is dismantled without affecting the safe...
