The principle of the existing converter water-cooling system has defects: because the two-way water supply enters the water rotary joint arranged on the non-driving side and mixes together, then it is divided into two water-way outlets from the water rotary joint, and each is divided into several ways through their respective water distributors. Lead to the water-cooled furnace mouth and furnace cap respectively, and the two channels of water flow out through the water rotary joint after circulating through the water-cooled furnace mouth, furnace cap and trunnion support ring
Therefore, this water-cooling system does not separate the cooling water of the water-cooled furnace mouth and the furnace cap. In actual production, if there is a failure in one of the channels, the cooling water supply of the entire converter system must be stopped, thereby affecting the production of steelmaking.

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 , Figure 7 with Figure 8 As shown, a converter water cooling system according to the present invention includes a water rotary joint 11, a non-driving side trunnion 12, a furnace mouth coil, a furnace cap ring pipe, a driving side trunnion and a supporting ring. The water swivel joint adopts a separate two-in-two-out mode. This method mainly means that the water rotary joint is provided with two water inlet pipes and two water outlet pipes, and the non-driving side trunnion is provided with two in-shaft water inlet pipes and two in-shaft water outlet pipes. And the plane where the in-shaft water inlet pipe and a port of the in-shaft water outlet pipe are located and the plane where the outer ports of the water inlet pipe and the water outlet pipe in the water circulation joint are located are sealed and docked in the corresponding manner of...

The invention discloses a converter water cooling system and a water swivel for the converter water cooling system. The water swivel comprises a hollow shaft and a hollow shell, wherein the hollow shell is sheathed outside the hollow shaft to form a clearance space; the clearance space is divided into four annular diversion chambers through a plurality of space rings; the hollow shell is provided with four shell holes, and each shell hole is corresponding to one diversion chamber; two outer water inlet pipes and two outer water outlet pipes are respectively connected with the four shell holes; the hollow shaft is provided with four shaft holes, and each shaft hole is corresponding to one diversion chamber; two inner water inlet pipes and two inner water outlet pipes are arranged in the hollow shaft and respectively connected with the four shaft holes; and the inner and outer water inlet pipes and the inner and outer water outlet pipes are respectively communicated with one diversion chamber. The water swivel implements independent cooling water supply of the water cooling furnace hole and furnace cap, thereby implementing independent control; and the water inlet and water return of the converter water cooling system are arranged at the non-driving side of the converter, so the converter water cooling system has the advantages of simple and compact structure and installation space saving, is convenient to operate and maintain, and satisfies the practical production demands.
Description
technical field [0001] The invention relates to a water rotary joint for a converter water cooling system and the converter water cooling system. Background technique [0002] The water cooling system of the converter is an important guarantee to prolong the service life of the furnace equipment. The system is a device for cooling the water-cooled furnace mouth, furnace cap and trunnion support ring. The principle of the existing converter water-cooling system has defects: because the two-way water supply enters the water rotary joint arranged on the non-driving side and mixes together, then it is divided into two water-way outlets from the water rotary joint, and each is divided into several ways through their respective water distributors. They respectively lead to the water-cooled furnace mouth and the furnace cap, and the two channels of water flow out through the water rotary joint after circulating through the water-cooled furnace mouth, furnace cap and trunnion suppor...
