Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0030] Reference Figure 1 ~ Figure 7 As shown, in an embodiment of the present invention provides a method for installing a water-cooled cable for a refining furnace. The end of the water-cooled cable 4 connected to the short network 1 of the transformer 9 is the first terminal, and the water-cooled cable 4 is connected to the electrode cross arm 8. One end is the second end, and the installation method includes the following steps:
[0031] 1) Install and fix the transformer 9 and the cross arm 8 of the refining furnace motor;
[0032] 2) Put the clamps 5 on both ends of the water-cooled cable 4;
[0033] 3) The crane hook 6 hangs the second end of the water-cooled cable 4 through the steel wire rope 7, and the water-cooled cable 4 is lifted vertically, and then transported by the crane to the docking position with the short net 1;
[0034] 4) Park the first end of the ...

The invention discloses an installation method of a water cooling cable of a finery. The method comprises the following steps that the two ends of the water cooling cable are sleeved by clamps respectively, and hooks are mounted in an interface of a short network; a suspension hook of a bridge crane connects the water cooling cable with one end of an electrode cross arm via a steel rope and hangs up the water cooling cable; the other end, connected with the short network, of the water cooling cable is put vertically downwardly in a position under the interface of the short network; the hooks are mounted in the interface connected to the short network; the hooks are connected with the clamps via chain blocks respectively; the height of the suspension hook of the bridge crane is decreased, the end, connected to the short network, of the water cooling cable is changed from vertically downwards to vertically upwards; the chain blocks are contracted, aligned an interface of the water cooling, and connected with the interface; the suspension hook of the bridge crane is elevated so that the water cooling cable is accurately aligned with a port connected to the electrode cross arm of the finery and connected with the port; and the chain blocks, the clamps, the hooks and the steel rope are dismounted successively, and the water cooling cable is installed. The installation quality of the water cooling cable can be ensured, procedures are reduced, the construction difficulty is reduced, and the construction efficiency is improved effectively.
Description
Technical field [0001] The invention relates to the technical field of equipment installation, in particular to a method for installing a water-cooled cable for a refining furnace. Background technique [0002] In the equipment components of the LF refining furnace of the metallurgical steelmaking system, each water-cooled cable weighs about 1 ton, with a rubber hose on the outer layer and soft conductive metal inside. The thickness of the connecting copper plate with holes at both ends is about 50-60 mm, and one end is connected to The short net on the transformer side is connected, and one end is connected with the electrode cross arm. In the traditional method of installation, a soft sling is used to hoist the middle of the water-cooled cable, which causes the cable head to be unable to be vertical. The installation is difficult due to the influence of the site and the properties of the water-cooled cable itself. [0003] In view of the above problems, a method for installing w...
