Problems solved by technology

It is too late to replace when the production is tense, which may overload the ladle car or cause the slag basin to overflow, which is not good for safety
This bearing method also has the following disadvantages in actual operation: ①The slag basin is easily damaged by sudden cooling and sudden heat
②The crane needs to cooperate with the operation in the process of replacing the slag basin, and the crane has potential safety hazards in the process of transferring the slag basin
③ It takes a long time to replace the slag basin, which brings passiveness to production
④Because there is a lot of slag accumulated on both sides of the lugs of the ladle car after the steel is placed, it is necessary to frequently get on and off the ladle car during manual cleaning, and the labor intensity of the workers is high. Hidden danger
[0003] At the same time, during the process of slag discharge, the high temperature waste slag will also cause the danger of burning the working cables of the ladle car

Embodiment 1

[0033] figure 1 , 2 shown.

[0034] A ladle car under a converter furnace, comprising a car body 1 and a ladle 2; the car body includes a ladle car seat frame 3 located under the ladle, and slag basin shelf frames 4 located on both sides of the steel ladle 2; Splash guards 5 are installed on both sides of the frame 4, and an inclined slag discharge channel 6 is arranged between the oppositely arranged splash guards 5. In the inclined slag discharge channel 6, the end far away from the ladle 2 is lower than the end close to the ladle 2. horizontal position.

[0035] The inclined angle of the inclined slag discharge channel 6 is 50°.

[0036] The bottom edge of the inclined slag discharge channel 6 is connected with a slag guide edge 7 protruding from the vehicle body. The slag guide edge is a steel plate or a fireproof board arranged horizontally.

[0037] The splash guard 5 is a 10cm thick steel plate.

[0038] The slag discharge channel 6 is a steel plate obliquely arra...

Embodiment 2

[0040] image 3 shown.

[0041] A ladle car under the converter furnace as described in Example 1, the difference is that the inclined angle of the inclined slag discharge channel 6 is 30°. The slag guiding edge 7 is an arc-shaped steel plate or a fireproof board. It ensures that the slag slides down to the bottom of the furnace smoothly, and protects the cables of the ladle car from being burned by the slag.

Embodiment 3

[0043] Such as Figure 4 , 5 shown.

[0044] A ladle car under the converter as described in Example 1, the difference is that an integral slag discharge mechanism including a splash guard 5 and an inclined slag discharge channel 6 is provided on the slag basin shelf 4; The slag discharge mechanism includes a vertical baffle 8 and a bottom plate 9 close to the ladle, and the splash baffle 5, the vertical baffle 8 and the bottom plate 9 together form a slag discharge area; the bottom plate 9 of the overall slag discharge mechanism is close to The position of the ladle 2 is provided with a rotating fixed shaft 10, and the integral slag discharge mechanism rotates along the rotating fixed shaft 10;

[0045] On both sides of the bottom of the integral slag discharge mechanism, and on the slag basin shelf 4 are respectively provided with assembly grooves 11 for placing hydraulic jacks 12, and a part of the assembly grooves 11 is exposed to the integral discharge On both sides of...

Abstract

The invention relates to a ladle buggy under a converter which comprises a buggy body and a ladle. The buggy body comprises a ladle buggy saddle under the ladle and a slag pot placement frame located on the two sides of the ladle, the two sides of the slag pot placement frame are provided with anti-splashing baffles, inclined slag discharging channels are arranged between the oppositely arranged anti-splashing baffles, and the ends, away from the ladle, of the inclined slag discharging channels are lower than the horizontal position of the ends, close to the ladle, of the inclined slag discharging channels. A traditional slag pot is replaced with the inclined slag discharging channels, the two sides of the ladle buggy body are provided with the inclined slag discharging channels, a certain slope is formed under the condition that crane hooking and unhooking are not influenced, steel slag can slide to the converter along the slope in the steel discharging process and cannot be accumulated in the buggy body, and the slag falling to the converter is directly pushed out of a slag aisle through a slag car. Meanwhile, in order to prevent high-temperature liquid from splashing and damaging and corroding staff and equipment, the two sides of the inclined slag discharging channels are provided with the anti-splashing baffles in an enclosed mode.

Description

technical field [0001] The invention relates to a ladle car under a converter and its application, belonging to the technical field of metallurgical equipment. Background technique [0002] At present, the ladle cars used by most steel mills carry the ladle and slag basin during use, and it takes time to replace the slag basin when it is full of converter slag. It is too late to replace when the production is tense, which may overload the ladle car or cause the slag basin to overflow, which is not good for safety. This bearing method also has the following disadvantages in actual operation: ①The slag basin is easily damaged by sudden cooling and sudden heat. ②The crane needs to cooperate with the operation in the process of replacing the slag basin, and there are potential safety hazards in the process of transporting the slag basin by the crane. ③ It takes a long time to replace the slag basin, which brings passiveness to production. ④Because there is a lot of slag accum...
