Problems solved by technology

Due to the deep bottom of the ladle, dark light, and high temperature (about 800°C), it is difficult to accurately place the throwing drainage agent, the amount of throwing is large, the effective utilization rate is low, the throwing time is long, and the working environment is harsh; especially when installing or cleaning sliding During the nozzle and transportation process, the ladle turns and shakes, and the residues and debris in the ladle fall off, and it is easy to fall into the flow steel hole of the upper nozzle and the upper slide plate, or cover the upper nozzle, or the drainage agent is damp, etc. The reason is that the flow steel hole is often blocked; to deal with the flow steel hole blockage, it will take a lot of manpower, material resources and time, and it is not safe; even the drainage fails, and the whole package of molten steel is scrapped, which seriously affects the production.

Embodiment 1

[0023] Embodiment 1: As can be seen from Fig. 4, the sheath pipe is a graphic pipe, and the pipe wall is provided with a grid-shaped hole 5, which is made of a thin plate with a grid such as a steel plate, and a stopper 6 is provided in the head and tail. The tube 2 is clamped in the sheath tube 1, and the paper tube 2 is clamped by the blocking card. The wall of the sheath pipe 1 is grid-shaped and easy to melt.

Embodiment 2

[0024] Embodiment 2: As can be seen from FIG. 5 , the sheath pipe 2 can also be connected by a steel wire 7 and a ring 8 , welded into a fence shape, and a retaining card 6 is arranged inside. Such a sheath tube 1 is easily melted.

Embodiment 3

[0025] Embodiment 3: As can be seen from FIG. 6 , the sheath tube 1 can also be a thick round tube made of wood, with a stopper 6 inside. The wooden tube has toughness, heat insulation, and is easy to burn.

[0026] Figure 3 is a diagram of the use state of the armored drainage agent plug. It can be seen from the figure that the drainage agent plug 1 is placed in the steel hole of the upper nozzle brick 9, the upper nozzle brick 9 is fixed in the nozzle seat brick 10, and the drainage agent plug is 1 head The part is higher than the water outlet seat brick 10, and the afterbody is positioned on the top of the upper slide plate 11, and must not extend to the lower slide plate 12.

[0027] When using, first check the use of the nozzle and the slide plate, if it can be reused, clean it, otherwise replace the nozzle and slide plate; then insert the armored drainage plug from the lower part, debug the actuator, close the slide nozzle, and ensure the operation The performance is co...

Abstract

A jacketed draining agent plug for the sprue of casting ladle is prepared through loading the draining agent in packing bag, putting the packing bag in a paper pipe, and fixing the paper pipe in a protecting sleeve. Said draining agent plug can be directly inserted in the sprue of casting ladle.

Description

technical field [0001] The invention belongs to auxiliary equipment for ladle starting casting operation, in particular to a device for draining molten steel and a method for setting the draining agent when casting starts from the flow hole at the bottom of the ladle. Background technique [0002] Casting is an important process of steelmaking production. The smelted molten steel is cast directly or after refining through the ladle. In the early days, the pouring gate at the bottom of the ladle used a plunger valve, and the plunger plug was used to control the closing and opening of the pouring gate to control the flow of molten steel. Because the movement of the plug is difficult to control, and the plug is easy to fall off, it is gradually abandoned. In recent years, the casting gate at the bottom of the ladle mostly adopts a sliding nozzle. The sliding nozzle mechanism is installed on the outside of the bottom of the ladle, the upper nozzle is fixed in the nozzle block,...
