Description
Technical field
The mobile fire-screen door device that air brick core steel bonding operation is burnt in a kind of ladle-pot hot-repair bottom blowing is the utility model is related to, belongs to steel
Bag hot repair technical field of auxiliary equipment.
Background technology
Molten steel tapped after Converter to continuous-casting steel pouring terminate during domestic demand to be placed in ladle, molten steel is warm during this period
Degree reduces, damaged portion heat.In order to reduce molten steel refining smelting procedure ton is reduced in intermediate link thermal loss, final realize
Steel electric quantity consumption purpose, steel mill generally using terminate from converter tapping to continuous-casting steel pouring link carry out ladle is capped,
Reducing temperature in the ladle memory storage molten steel unit interval reduces amplitude.
But in production period due to various odjective causes, it is difficult to realize and turnover ladle 100% is capped, be capped ladle
Ladle is not capped to be both needed to be had a swollen head bottom air brick core steel bonding, because bag mouth regional temperature is higher, capped steel with oxygen pipe in slide plate region
Bag slide plate work need to stand to be carried out grilling thoroughly gaseous core steel bonding operation on the ground beyond 2 meters of bag mouth, is not capped ladle and is difficult to stand
Carry out grilling thoroughly gaseous core steel bonding operation immediately ahead of bag mouth, and wrap Nei Wenduda 800~1000OC, it is internal discrete that oxygen lance stretches into bag
Quarter is red by burning, because the distance bag nearlyer spot temperature in bottom is higher, burns oxygen pipe and is burnt red be bent downwardly in the close bottom position leading portion that wraps
Deviate position immediately ahead of air brick core, influence slide plate work and burn air brick core steel bonding operation.Capping ladle burns oxygen pipe and rides over steel ladle cover
Drainage sand hole is added to carry out operation, if oxygen pipe leading portion, which is bent downwardly that the outer oxygen pipe of bag can be pushed, realizes that oxygen pipe leading portion and air brick core exist
Same level is completed to burn steel bonding operation.Uncovered ladle burning oxygen pipe can only ride over bag and wrapped along standing along the progress of the flank side surface of front two
Operation, if oxygen pipe leading portion is bent downwardly because bag is along from the ground compared with early work industry limited space, it is difficult to reached by will wrap outer oxygen pipe and push
To oxygen pipe leading portion and air brick core in same level situation, influence to burn air brick core steel bonding operation.If 2 meters immediately ahead of bag mouth
Block fireguard is put at place, can by burn oxygen pipe ride over fireguard grill thoroughly stomata main room stretch into bag in complete burn air brick core steel bonding operation,
But placing fixed fireguard influences to grill thoroughly gas brick core steel bonding operation to capping ladle, and placing or do not place fixed fireguard can not be same
When solve processing burn air brick core steel bonding shop problem, need further improvement badly.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mobile fire-screen door device of ladle-pot hot-repair bottom blowing processing,
The rapid translating of the ventilative steel bonding handling process of ladle-pot hot-repair can be realized to capping ladle and be not capped to this device, convenient, fast
Ladle bottom blowing porous core steel bonding processing is completed promptly.
Solve above-mentioned technical problem technical scheme be：
A kind of mobile fire-screen door device of ladle-pot hot-repair bottom blowing processing, it is by fire-screen door, moving cart, moving cart track groups
Into fire-screen door is upright rectangle, and fire-screen door top has rectangular fire-screen door to burn air brick steel bonding mouth, moving cart track
It is laid on hot repair to fall in front of steel ladle opening position, the length of moving cart track is more than twice of fire-screen door width, fire-screen door
Width matches with ladle mouth diameter, and the lower end of fire-screen door is fixedly mounted in moving cart, and it is small that moving cart is placed on movement
On track road.
The above-mentioned mobile fire-screen door device of ladle-pot hot-repair bottom blowing processing, the distance of the moving cart track and steel ladle opening are big
In 2 meters.
The beneficial effects of the utility model are：
The utility model can be placed on hot repair ladle and fall to hot repair platform, and capping ladle will move fire-screen door along rail
Road direction is pushed into place from position immediately ahead of ladle mouth, burns bottom blowing oxygen hose and through steel ladle cover grills thoroughly air-core hole and stretch into ladle and carries out
Gaseous core steel bonding is grilled thoroughly, ladle is not capped and mobile fire-screen door is pushed into position placement immediately ahead of ladle mouth along track, burn bottom blowing oxygen
Pipe stretches into ladle through the fire-screen door burning air brick steel bonding mouth in mobile fire-screen door and carries out grilling thoroughly gaseous core steel bonding, quickly and easily
Complete ladle bottom blowing porous core steel bonding processing.
The utility model have simple in construction, reliable operation, simple installation, it is light and handy flexible the advantages of, can effectively solve
Certainly it is capped ladle and is not capped the rapid translating of ladle bottom blowing porous core steel bonding processing.
Brief description of the drawings
Fig. 1 is the utility model and capping ladle ventilating processing schematic diagram；
Fig. 2 is Fig. 1 top view；
Fig. 3 is the utility model and is not capped ladle ventilating processing schematic diagram；
Fig. 4 is Fig. 3 top view.
Marked in figure as follows：Hot repair ladle 1, fire-screen door burn air brick steel bonding mouth 2, fire-screen door 3, moving cart track 4, shifting
