Oxygen supply system for blast furnace ironmaking taphole of iron mill

Abstract

The invention discloses an oxygen supply system for a blast furnace ironmaking taphole of an iron mill. The system comprises an oxygen supply gun, an air outlet pipe, a protection pipe, an air supplypipe, an air conveyor, an oxygen pipe and an oxygen conveyor, the oxygen supply gun is fixedly connected with an air outlet pipe; a gun head is fixedly connected to the right end part of the oxygen supply gun; the left end of the oxygen supply gun is fixedly connected with a gas supply pipe and an oxygen pipe; one end, deviating from the oxygen supply gun, of the gas supply pipe is fixedly connected with a gas conveyor; the end, away from the oxygen feeding gun, of the oxygen pipe is fixedly connected with an oxygen conveying machine, the oxygen feeding pipe and the oxygen pipe are communicated through a communicating pipe, a communicating valve is connected to the communicating pipe in series, and a stop valve, a third adjusting valve, a second barometer, an oxygen instantaneous flow metering totalizer and a fourth adjusting valve are connected to the oxygen pipe in series. Through the arrangement of the oxygen feeding gun, the gas outlet pipe, the protection pipe, the gas feeding pipe, the gas conveying machine, the oxygen pipe and the oxygen conveying machine, the problems that a traditional treatment method is unsafe, not environmentally friendly, not economical, not efficientand even illegal are solved.

Description

technical field [0001] The invention relates to the technical field of oxygen supply to a blast furnace ironmaking taphole, in particular to an oxygen supply system for a blast furnace ironmaking taphole in an ironworks. Background technique [0002] Newly built and put into use blast furnaces, blast furnaces restarted after major or medium repairs, or blast furnaces with relatively large abnormalities in furnace conditions due to major fluctuations in the physical and chemical properties of raw materials or improper operation during normal production, etc., If the furnace condition is abnormal, it often means that there is no wind, no slag, and no iron. Generally, there is no output, quality and benefit at all. Decades of practical experience in production have given birth to the fact that the implementation of oxygen supply to the iron hole has become an important means to quickly restore the furnace condition. The traditional method of dealing with abnormal furnace condi...
