AI Technical Summary

Technical Problem

The number and cooling area of ​​the existing iron smelting blast furnace cast iron cooling walls are limited, resulting in low heat exchange efficiency, high wall temperature and short service life.

Method used

The sweating cooling technology is adopted, and the gap between the cooling wall and the cooling water pipe is set up between the cooling wall body and the cooling water pipe, and the deodorization water seeps into these gaps under pressure at the pressure, exuded from the high temperature side to the cooler wall surface to achieve high -efficiency cooling.

Benefits of technology

The heat exchange efficiency of the cast iron cooling stave is improved, the wall temperature is reduced, the service life is extended, and the use of coolant is reduced.

Abstract

A sweating type cast iron cooling stave for an ironmaking blast furnace relates to the technical field of blast furnace cooling devices, comprising a cast iron cooling stave body and a plurality of cooling water pipes pre-set in parallel therein, the cast iron cooling stave body being located at the inlet and outlet ends of the cooling water pipes, and also provided with water injection cavities formed by protective pipes and cooling water pipes, the present invention injects deionized water into the cavity as evaporating water, and the deionized water penetrates into the cooling stave body through the gap between the cooling stave body and the cooling water pipes under pressure. The deionized water that penetrates into the body penetrates to the surface of the cooling stave through the microscopic gaps of the cooling stave body, and the seeped deionized water evaporates under heat to take away the heat of the cooling stave body, thereby providing efficient cooling for the cooling stave body.
