Description

Bessemerize carbon monoxide rifle bit manipulation method
Technical field
The invention belongs to steelmaking technical field, be specifically related to one and bessemerize operation.
Background technology
In steelmaking technical field, the process of bessemerizing adopts Oxygen control method conventionally, and operative employee mainly relies on and observes flame variation, judges variations in temperature and change slag effect in stove. This kind of method operation easier is large, observes not intuitively, and error is larger, easily causes splash, returns the problems such as dry.
The object of this invention is to provide one and bessemerize carbon monoxide rifle bit manipulation method, large to solve prior art operation easier, to observe not intuitively, error is larger, easily causes splash, returns the problems such as dry.
The technical solution adopted for the present invention to solve the technical problems is to adopt the blowing of carbon monoxide rifle bit manipulation method, overall process can be according to the fluctuation of carbonomonoxide concentration, the variation of carbonomonoxide concentration is that numeral changes, change rhythmical adjustment rifle position in conjunction with flame, use overall process appropriate and can accomplish that slag does not return dry, not splash, and can control temperature in stove and evenly rise, can take measures in advance to reaction in furnace, be conducive to automation control, make converting process more steady. Concrete operation method is as follows:
Pack into and finish to falling rifle blowing from being blended into the metal charge such as molten iron, steel scrap, add after a batch of material, master control work is carried 100-200mm rifle position slag, then observe the variation of coal gas detection system carbonomonoxide concentration, if do not get rid of slag sheet in stove, carbonomonoxide concentration has met or exceeded 25%, and has the trend that continues rising; Need in stove, add the iron-stone of 200-500kg as early as possible, and suitably carry rifle 30-50mm, can control temperature rise too fast, avoid reaction between carbon and oxygen aggravation, be unfavorable for the fusing of a batch of material, in addition can help slag; In stove, add ore observation carbonomonoxide concentration to change downward trend into by rising, now press 50-100mm and reduce rifle position, carbonomonoxide concentration is reduced to 10% left and right, illustrates that slag progressively melts.
Described iron-stone is that sintering deposit, pellet, raw ore are wherein a kind of.
Adopt good effect of the present invention to be:
1. adopt the blowing of carbon monoxide rifle bit manipulation method, overall process can, according to the fluctuation of carbonomonoxide concentration, change rhythmical adjustment rifle position in conjunction with flame, uses overall process appropriate can accomplish that slag does not return dry, not splash. And can control temperature in stove and evenly rise, highly beneficial to process temperature control.
2. the variation of carbonomonoxide concentration is that numeral changes, and than observing, flame is more directly perceived, can take measures in advance to reaction in furnace, is conducive to automation control, makes converting process more steady.
