Description
Technical field
The present invention relates to blast furnace operation technology field, more particularly to a kind of bottom house air port work based on fixed point radar
Make condition evaluation method.
Background technology
Modern blast furnace has the characteristics that bulky, reaction process are complicated as a kind of huge ironmaking production reactor.
Blast furnace production process loads furnace charge from top, and hot wind is blasted from lower part, after bottom house blasts hot wind, the O in hot wind2Meeting and Jiao
Vigorous combustion occurs for C in charcoal, generates CO gases, while release substantial amounts of heat so that and air port regional temperature reaches 2150~
2400 DEG C, the N brought into heat air2, CO and N2Collectively form high temperature blast furnace gas, these coal gas from bottom house by
Upper blast furnace is gradually risen to, on the one hand blast furnace heating gas heats furnace charge in uphill process, on the other hand reduces ore.Under blast furnace
Portion's blast velocity reaches more than 200m/s, and a large amount of hot-airs of such high speed blast bottom house, the O in hot-air2And coke
While chemical reaction, the coal gas of generation can rotate near air port, a coke phase is produced in air port region
To active space, this Spatial General 6 R is referred to as In Raceway Before Tuyere of Blast Furnace, and raceway zone has certain olive shape.Raceway zone
Depth is an important controlling indicator, and the size of the depth, change can directly affect the initial distribution of blast furnace gas, so that
VELOCITY DISTRIBUTION, the heat distribution of rising Gas Flow are influenced, the thermo parameters method inside blast furnace is influenced, so as to determine the reduction of blast furnace
Efficiency and operation of blast furnace quality.So blast furnace worker pays close attention to the control of In Raceway Before Tuyere of Blast Furnace.
《Ironmaking》1991.3 (43) .43~45. disclose the topic production practices of theoretical tuyere combustion temperature in order to control
Article, this article propose a kind of method using theoretical temperature combustion evaluation tuyere area working condition before air port.This method is
The heat input status before air port is evaluated using the theoretical temperature combustion of the coal gas to burn before heat balance theoretical calculation air port,
The index is a kind of off-line calculation pattern at present, and this method cannot calculate the length of tuyere area, and the length of tuyere area and Jiao
The calorific intensity of charcoal, Characteristics of Slags, coke size, air port incoming air area, air port setting angle etc. have relation, theoretical temperature combustion
Influence of these factors to Tuyere Raceway length can not be reflected.
The 1970s and 1980s in last century Wuhan Iron and Steel Plant iron-smelter uses a kind of method for directly measuring Tuyere Raceway length.The party
Method is in blast furnace course of normal operation, is depressured by checking, and air port tegillum is opened manually, and tuyere area is directly measured using drill rod
Length, the convolution region length in air port of measuring method measurement can not represent actual state, because being at this time conjunction measuring
Blast furnace reduced air blast, reduce pressure.This method can be with an examination, for internal volume in the case of small furnace, low top pressure
2000m3More than, the large blast furnace of more than top pressure 0.2MPa, it is very big to carry out convolution region measurement danger by opening air port tegillum.
