Description

[Detailed description of the invention] Conventionally, metallurgical furnaces, ceramic furnaces, metal heating furnaces, converters, ladles,
The refractory layer for the inner lining of tongues, tap troughs, tap troughs, and slag troughs can be formed by layering bricks, or by molding or lining castable refractories mixed with fine refractory powder at the work site or by transporting them. It had been.

Therefore, a lot of working time and labor is required, and the manufacturing cost is also high.

The present invention aims to eliminate these drawbacks and provide a castable refractory lining device that can form a refractory layer mechanically and in a short time.

In this invention, a device stand 1 is installed above metallurgical furnaces, ceramic furnaces, metal heating furnaces, converters, ladles, etc., and a lifting platform 2 that can rise and fall and rotate freely is attached to the bottom of the device stand. This relates to a castable refractory lining device in which a pouring pipe 4 communicating with a castable refractory supply pipe 3 is pivotally attached to a lower part of the refractory so as to be able to change its inclination angle.

In the figure, 5 is a lifting platform support frame that holds the lifting platform 2, and 6 is a lifting support frame 5 that is positioned below a holding frame 30 vertically installed on the lower surface of the equipment table 1 in order to allow the pouring pipe 4 to rotate freely. The attached gear 7 is a worm that is attached to the lifting platform 2 and meshes with the gear 6, and is driven by an electric motor or the like to rotate the lifting platform 2 and the pouring pipe 4, and 8 is a worm that allows the pouring pipe 4 to be raised freely. 9 is a wheel for making the equipment platform 1 moveable; 10 is a rotary joint; 11 is an operation room; 1
2 is a television camera attached to the tip of the pouring pipe 4 to observe the pouring state of the castable refractory vIJ13, 14 is a converter, 15 is a formwork, 16 is a supply hose, 17-
27 is a device part for producing castable refractories, 17 is a pressure pump, 18 is a water pressure pump, 19 is a material hopper, 20 is a mixer, 21 is a motor that drives the mixer, and 22 is a part that measures and mixes water. water meter, 23
2 is a weighing tank for weighing powdered refractory raw materials; 24 is a powder supply device; 25 is a powder tank for storing powdered refractory raw materials; 26 is a container bag for carrying powdered refractory raw materials;
7 indicates a rail.

In this device, the castable refractories 13 in the form of clay are sent from the castable refractories supply pipe 3 to the pouring pipe 4, and poured between the converter 14 and the formwork 15 to perform lining. Since the angle of inclination of the converter 4 can be made variable by a hydraulic cylinder 8 or the like, it can be lifted upward according to the laminated thickness of the castable refractory 13.
, it is possible to adjust the closeness between the wall surface and the formwork 15, and furthermore, by rotating the lifting table 2 and the pouring pipe 4, it is possible to uniformly inject the castable refractory 13 along the inner circumference of the converter 14. Castable refractories 1 are removed by raising and lowering platform 2.
The vertical height of the spouting pipe 4 can be adjusted according to the laminated thickness of the spouting pipe 4.

Therefore, the castable refractory lining device according to the present invention has the following effects.

(1) Since the pouring pipe 4 can be raised and lowered and the angle of inclination can be changed, it can easily enter the inside of a container with a small opening such as a converter, and after entering, it can be tilted at the desired angle. A desired lining can be formed simply by turning.

Furthermore, since the angle of inclination is freely variable, lining can be performed easily and quickly regardless of the size of the container.

(2) Furthermore, since the pouring pipe 4 rotates integrally with the lifting platform 2 on which the worker and others are placed, the worker can always monitor the construction site of the pouring pipe 4 from a fixed position. .
