Abstract
The utility model belongs to a changing device of a ladle nozzle brick of a steel ladle used in a steel plant, and particularly relates to a ladle nozzle brick changing device. A steel ball is fixedly connected to the end part of a round steel with the diameter of 30mm, and the diameter of the steel ball is larger than the aperture of a nozzle of the ladle nozzle brick. The device has a simple structure and is convenient to operate, the ladle nozzle brick is convenient to change, the working condition can be improved, and the time and labor are saved.
Description
Technical field
The utility model belongs to the steel ladle that steel mill uses, the more changing device of its ladle nozzle brick, and particularly a kind of ladle nozzle brick is changing device more.
Background technology
Converter steel water-coating port brick just must be changed after using and reaching the life-span, ladle bag labour life-spans 95 stove/bag, ladle nozzle brick life-spans 10 stove/, converter production requirement ladle must use under the condition of high temperature continuously to reduce temperature loss, need carry out in the condition of high temperature so change.Original ladle nozzle brick is changed and is removed with pneumatic pick.
Change ladle nozzle brick environment temperature height (1100 ℃); Worker's labour intensity is big; After refractory material used, intensity was bigger, removed difficulty; Use pneumatic pick to need dynamic medium expense height.
The ladle nozzle brick adopts outer dress method, is installed in the pocket block, and is full in order to guarantee to fill pug between brick cup and nozzle brick, satisfies the requirement that steel is not worn in the nozzle brick assembling, is cone match between brick cup and nozzle brick.It must be removed from the outside when changing the ladle nozzle brick.Because the ladle nozzle brick is a magnesia carbon refractory, middle to fill pug be high-alumina chamotte, do not have impetus again through high temperature sintering intensity is higher in process of production, has only to smash the back with pneumatic pick and take out.
Summary of the invention
The purpose of this utility model is to provide more changing device of a kind of ladle nozzle brick, and it is simple in structure, and it is convenient, easy to operate to change the ladle nozzle brick, can improve working conditions, time saving and energy saving.
The purpose of this utility model is achieved in that more changing device of a kind of ladle nozzle brick, at diameter be the end of round steel of 30mm affixed steel ball, the diameter of steel ball is bigger than the aperture, the mouth of a river of ladle nozzle brick.
The ladle nozzle brick is changing device more, because of method of operating is that the utility model is inserted from the ladle mouth, utilize aperture, the ladle nozzle brick mouth of a river poor with the device steel ball size, steel ball is stuck in the nozzle brick front portion, utilize the inner small and outside big conical surface characteristics of nozzle brick appearance and size, catch round steel to be pulled outwardly, then just can pull out nozzle brick integral body very smoothly.
The utility model is simple in structure, and it is convenient, easy to operate to change the ladle nozzle brick, has improved condition of work, time saving and energy saving.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing,
Fig. 1 is a structural representation of the present utility model;
Fig. 2 changes the working state schematic representation of ladle nozzle brick for the utility model.
The specific embodiment
A kind of ladle nozzle brick is changing device more, as shown in Figure 1, at diameter be the end of round steel 1 of 30mm affixed steel ball 2, the diameter of steel ball 2 is bigger than the aperture, the mouth of a river of ladle nozzle brick 3.The diameter of steel ball 2 is 70mm.The length of round steel 1 is 2000-4000mm.As shown in Figure 2, cooperate for taper seat between brick cup 4 and the nozzle brick 3.When changing ladle nozzle brick 3, the utility model is inserted from the ladle mouth, utilize the diameter of ladle nozzle brick aperture, 3 mouth of a river and steel ball 2 poor, steel ball 2 is stuck in front portion, aperture, the mouth of a river, utilize the inner small and outside big taper seat characteristics of nozzle brick 3 appearance and sizes, can pull out nozzle brick 3 easily.
