Abstract

The utility model discloses a flow guiding sand container which comprises a flow guiding pipe and a flow guiding head. The flow guiding pipe and the flow guiding head are mutually communicated. The flow guiding pipe is a hollow cylinder. A pipe cover is arranged at the end, far away from the flow guiding head, of the flow guiding pipe. The flow guiding head is a hollow conic body. The bottom of the flow guiding head is connected with the flow guiding pipe. The top of the flow guiding head is closed. According to the flow guiding sand container, a ladle nozzle can be accurately filled with flow guiding sand, pouring is accurate, and consumption of the flow guiding sand is reduced; the ladle nozzle whole cover-adding technology can further be achieved, heat loss is low, energy is saved, and the efficiency is high; meanwhile, the operation environment of a worker is improved.

Description

A kind of stuffing sand container

Technical field

The utility model belongs to technical field of ferrous metallurgy, relates to a kind of stuffing sand container.

Background technology

In steelmaking process, molten steel is poured ladle into from smelting furnace, and ladle winches to appointed place, opens ladle nozzle slide plate, pouring molten steel in conticaster tundish or various mould.Ladle nozzle has certain depth, and its numerical value is because of ladleful difference difference, generally in 400-600mm scope; Its diameter is generally in 35-80mm scope.If before slide plate is opened, molten steel enters the mouth of a river, can solidify very soon in the process moving at ladle, arrive after assigned address drainage molten steel smoothly.Need in the mouth of a river, to pour in advance stuffing sand, current technique is, after ladle has been cleared up for this reason, close upper slide, ladle is put and is transported to just afterwards assigned address, from ladle upper oral part, by artificial or mechanical drainage system, stuffing sand is poured into the mouth of a river, and then ladle is transported to roasting package location toasts.Its shortcoming is that the new technology that cannot realize steel ladle full stroke covering reaches energy-conservation target; Stuffing sand in the process pouring into because location difficulty consumes larger; It is lower that ladle cleaning and filling sand operate two step work operations efficiency; Need of work is in the face of ladle mouth high-temperature operation, and its temperature is up to more than 1300 ℃.

Utility model content

The purpose of this utility model is to provide, and to solve in the existing process that pours into stuffing sand, stuffing sand consumption is too much, heat loss many and the poor problem of manual work condition.

The technical scheme that the utility model adopts is, a kind of stuffing sand container, comprise the drainage tube and the drainage head that are interconnected, drainage tube is hollow cylinder, drainage tube is provided with pipe lid away from one end of drainage head, drainage head is hollow cone, and the bottom of drainage head is connected with drainage tube, the top seal of drainage head.

Feature of the present utility model is also,

The diameter of drainage tube equates with the bottom surface circular diameter of drainage head, and the diameter of drainage tube is identical with the minimum of a value of the diameter at the mouth of a river of ladle, the long 1～2cm of length at the Length Ratio mouth of a river of drainage tube.

The bottom surface of drainage head and the angle of its bus are 25 °～85 °.

The wall thickness of drainage tube, drainage head and pipe lid is 0.1～5mm.

The beneficial effects of the utility model are, by a kind of stuffing sand container of the present utility model, make stuffing sand can accurately be full of ladle nozzle, and lower filling is accurate, has reduced the consumption of stuffing sand; The technique that can also realize ladle mouth full stroke covering, heat loss is few, efficient energy-saving; Also improved workman's operating environment simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of stuffing sand container of the utility model;

Fig. 2 is the use schematic diagram of a kind of stuffing sand container of the utility model.

In figure, 1. drainage tube, 2. drainage head, 3. pipe lid, the 4. mouth of a river, 5. ladle, 6. lower skateboard.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The utility model provides a kind of stuffing sand container, its structure is referring to Fig. 1, comprise the drainage tube 1 and the drainage head 2 that are interconnected, drainage tube 1 is hollow cylinder, drainage tube 1 is provided with pipe away from one end of drainage head 2 and covers 3, drainage head 2 is hollow cone, and the bottom of drainage head 2 is connected with drainage tube 1, the top seal of drainage head 2.

Wherein, the diameter of drainage tube 1 equates with the bottom surface circular diameter of drainage head 2, and the diameter of drainage tube 1 is identical with the diameter minimum of a value at the mouth of a river 4 of ladle 5, the long 1～2cm of length at the Length Ratio mouth of a river 4 of drainage tube 1; The bottom surface of drainage head 2 and the angle of its bus are 25 °～85 °; Drainage tube 1, drainage head 2 and pipe cover 3 wall thickness and are 0.1～5mm.

During use, first stuffing sand is packed in drainage tube 1 and drainage head 2 into lid upper tube cap 3; Ladle 5 was fallen again, and with oxygen lance, purged the mouth of a river 4, and then the stuffing sand container of filling stuffing sand was filled in to the mouth of a river 4 from lower skateboard 6, and then closed lower skateboard 6, ladle 4 just hangs, and ladle 4 directly enters stand-by state; Because stuffing sand container is flammable material, as papery or plastics, so can burning under the high temperature of stuffing sand container when operation, then, just stuffing sand of its inner dress spill, can be completely and be full of accurately the mouth of a river 4.

Because stuffing sand adds before ladle 5 is standby, therefore can cover steel ladle cover directly to ladle 5, until before converter tapping, again steel ladle cover is opened, realized the complete full stroke covering that again fills with molten steel process to ladle of ladle 5 pouring molten steel in ladle, the exposed time of ladle mouth that has reduced ladle 5, heat loss is few, has saved the energy; While filling with sand work by a kind of stuffing sand container of the present utility model, operation is accurately simple, has reduced the loss of stuffing sand, has improved the operating efficiency of ladle 5, from cleaning ladle 5, to ladle 5, enters stand-by state, and the time can save more than 40%; Meanwhile, operating environment temperature is down to room temperature, has improved the condition of manual work.
