Description
Technical field
The utility model belongs to machinery equipment field, and in particular, to a kind of equipment for the repairing of mixed iron blast tapping hole.
Background technique
Mixed iron blast is steel mill storage molten iron, is homogenized the elevated temperature vessel of hot metal composition and temperature, while there is adjustment to produce
Save the function of gathering.Therefore, the long-life of metal mixer liner is the pursuit that each steel mill is common, unremitting.It is domestic to have mixed iron blast at present
About 500, capacity has 300 tons, 600 tons, 900 tons, 1300 tons to differ.
Before 2000, the inner lining material of mixed iron blast is fairly simple --- magnesia brick, clay brick, high-alumina brick.2000 extremely
More than ten years in 2014 are the stages of China's steel industry rapid development, and iron and steel output becomes 800,000,000 tons from 1.5 hundred million tons, resistance to
Fiery material yield becomes 29,000,000 tons from 12,000,000 tons.Yield, kind and the construction technology of refractory material have also obtained very big
Development.
The inner lining material of mixed iron blast has high-alumina brick, corundum brick, corundum-mullite brick, aluminum silicon carbide brick, corundum-mullite to pour
Material feeding, aluminium silicon carbide castable, high-strength light castable etc. build furnace technology also from single brick technological development to brick work
Skill, mixing furnace building process, integrated poured three kinds of technique are simultaneously deposited.
No matter which kind of technique and material make the mixed iron blast of liner, use as a servant the later period in furnace, tapping hole bottom is often damaged（It invades
It loses, wash away）Comparatively fast.Blowing out repairing takes time and effort, and works under hard conditions and dangerous, upsets subsequent STEELMAKING PRODUCTION section and gather.Such feelings
Under condition, most effective method is directly had a snack to the position.Material used by having a snack has refractory brick and castable refractory, and resistance to
Firebrick is difficult in conjunction with liner body itself, it is necessary to fixation is combined using castable.Comprehensively consider, simpler method is direct
It is had a snack with castable.
Mixed iron blast tapping hole frontage dimension is 400mm × 600mm, extends 2.5 ~ 3m into furnace, is 1250 DEG C or more in furnace
High temperature liquid iron and gas, apart from ground about 10m height, surrounding is hanging.How the castable being stirred, which is transferred to mixed iron blast, goes out
It is a difficult point in iron mouth.Using pumping machine equipment conveying, of a high price, uneconomical, waste of material is also big.Expected by artificial station
On bucket, material is got rid of into furnace with spade, dangerous, large labor intensity, speed are too slow and effect is also bad.
