Converter main body water, gas and hydraulic medium direction layout structure and a converter

Abstract

The invention relates to a converter body water, gas and hydraulic medium direction arrangement structure and a converter including the arrangement structure, the arrangement structure is specifically: the cooling water enters the cooling water channel arranged inside the trunnion of the non-driving side, and flows from the trunnion of the non-driving side The upper panel of the support ring of the shaft block is pierced to distribute to each cooling water point, and then the cooling water points are converging into the cooling water channel inside the drive side trunnion for discharge; the gas medium and hydraulic medium are arranged on the non-drive side trunnion The external gas medium channel and hydraulic medium channel lead into the corresponding medium pipeline, and the medium pipeline is attached to the annular outer surface of the support ring and extends to the corresponding medium use point. This layout structure is reasonable in design, reliable and safe, avoids the situation that the cooling water pipeline is smashed by slag, and facilitates the repair and maintenance of various medium pipelines, which can greatly reduce investment and production costs.

Description

technical field [0001] The invention belongs to the technical field of steelmaking converters, and in particular relates to a converter body water, gas and hydraulic medium orientation arrangement structure and a converter including the structure. Background technique [0002] Converter water cooling system, bottom blowing system and hydraulic medium system provide important guarantees for the normal operation of the converter. There are mainly two types of existing converter cooling water, gas and hydraulic medium system settings: (1) all medium pipes are arranged inside the support ring trunnion at the support ring trunnion, and directly pass through the support ring panel; (2) At the trunnion of the trunnion, all the medium pipes are arranged outside the trunnion of the trunnion, along the outer ring end of the trunnion to each user point. [0003] There are mainly the following problems when the converter cooling water, gas and hydraulic medium systems are all arranged ...

AI Technical Summary

Problems solved by technology

[0003] There are mainly the following problems when the converter cooling water, gas and hydraulic medium systems are all arranged inside the trunnion of the support ring: (1) An anhydrous area needs to be set at the trunnion of the support ring for water, gas and hydraulic medium pipelines, which reduces the The water cooling effect of the support ring, so that the service life of the anhydrous part of the support ring will be significantly lower than that of the water area; (2) If the cooling water, gas and hydraulic medium pipes inside the support ring are damaged, special maintenance channels must be set up for the support ring. The inside of the support ring is very narrow, so it is very inconvenient to replace and overhaul; (3) When the medium channel in the support ring trunnion is damaged in the later stage of the converter service, the entire support ring trunnion needs to be replaced. Due to the large number of equipment, replacement is very difficult and expensive high

There are the following main problems in setting all the medium systems outside the trunnion of the support ring: (1) If the external cooling water, gas and hydraulic medium pipelines of the support ring are damaged, especially if the cooling water pipeline is damaged, if it encounters molten steel for smelting, it will cause Major safety accidents, so it is best not to set the waterway outside the support ring; (2) If slag falls between the support ring and the dog house (ie, the converter airtight cover) during the rotation of the converter, it is very easy to damage the medium pipeline; (3) ) When the medium pipeline is arranged outside the support ring, it needs to be welded on the support ring trunnion. Once the medium pipeline is damaged, the entire support ring trunnion needs to be replaced, resulting in time-consuming maintenance and replacement, and high maintenance costs
