Nickel fibers.Converter is divided into alkaline (being liner with magnesia or dolomite) and acidity (with siliceous material by the refractory material property of furnace lining
Expect for liner) converter；The position being blown into by gas in stove is divided into bottom blowing, top blast and side-blown converter；The gas used by blowing, point
For air blown converter and oxygen coverter.Pneumatic steelmaking is mainly the method for making steel using liquid pig iron as raw material；It is mainly characterized by：By turning
Each component (such as carbon, manganese, silicon, phosphorus) is chemically reacted with the oxygen being sent into stove in the physical thermal and the pig iron of liquid pig iron in stove
Caused heat, metal is set to reach composition and the temperature that tapping requires.Furnace charge is mainly molten iron and slag material (such as lime, stone
English, fluorite etc.), to adjust temperature, steel scrap and a small amount of cold pig iron block and ore etc. can be added.In convertor steelmaking process, iron
Carbon in water generates the mixed gas of carbon monoxide and a small amount of carbon dioxide, i.e. coal gas of converter with the oxygen being blown at high temperature.Turn
The generating capacity of producer gas is in a smelting process and unbalanced, and composition also changes, generally by the multiple smelting process of converter
The coal gas of recovery inputs gas storage holder, is conveyed to user after mixing again through cooling, dedusting.
Type of attachment is the upper hang of three penalty kick hinged bearings between existing steelwork converter body of heater and backing ring, and ball pivot is
One T-shaped integral way, the ball pivot of this monoblock type determines to all ball pivots must disassemble and could change during replacing,
Ball pivot is a hidden danger point of converter, and multiple fracture accident easily occurs for converter ball pivot, and fracture location occurs in ball pivot pillar spiral shell
Bolt root, pillar bolt is once be broken, it is necessary to which blowing out is handled, it is necessary to all disassembled to three ball pivots, and converter is jacked up
After change ball pivot, long construction period, the general replacement ball pivot time is about 6 days, drastically influence being smoothed out for production.

Line, the other end are provided with T-shaped external screw thread a, and the T-shaped external screw thread a is used to be connected with body of heater.
Further technical scheme of the present utility model is that the T connector lower end is circular arc.
Further technical scheme of the present utility model is that the pillar bolt is cylinder.
Further technical scheme of the present utility model is, the pillar bolt lower end is connected by T connector with backing ring, on
End is connected by screwing on nut with body of heater.
Further technical scheme of the present utility model is that the backing ring upper end is provided with support corresponding with T connector, is used for
Connecting T-shaped head.
Further technical scheme of the present utility model is that the support is provided with pin shaft hole a corresponding with pin shaft hole, is used
It is connected in T connector.
Further technical scheme of the present utility model, which is that the body of heater edge is provided with, is used for pillar bolt precession T connector
Edge hole.
It is of the present utility model further technical scheme be, the T-shaped external screw thread a by screw on nut make pillar bolt with
Body of heater connects.
Beneficial effect
The utility model, which will be cut with scissors, is divided into disassembled T connector and pillar bolt two parts, makes simple, it is easy to accomplish, it is standby
It is convenient that part is changed, and reduces and changes man-hour, using reliable, and effectively reduces the replacing globe-hinge time, has ensured that production is carried out.
