Problems solved by technology

Such a long swinging slag adding pipe greatly interferes with the operation on the pouring steel platform
There is also a slag feeding pipe that does not move to adjust the position of the slag outlet (EP0011650). The disadvantage is that the adjustment range of the slag outlet is limited, and it is not suitable for many contemporary wide slab continuous casting machines.

Embodiment Construction

[0016] The first embodiment of the present invention is shown in Fig. 1 and Fig. 2 . The movable trolley (112) loaded with the slag adding device is pushed to the center of the inner arc casting platform of the crystallizer (101) close to the crystallizer (101) by the handrail (11), and the trolley (112) is braked by foot (13) position. Curved wheels (14) and straight wheels (116) are arranged below the dolly to facilitate the movement and direction change of the dolly. The motor (108c) on the trolley (12) drives the transmission screw (15) to rotate, and the nut pair of the transmission screw (115) drives the translation device (117) and the slag bucket (107) on it to move together. There are 2 collecting ports (106) below the slag hopper (107), and the 2 slag feeding pipes (105) connected to the collecting ports are respectively obliquely extended to both sides of the nozzle (103) of the crystallizer, which can shorten the slag hopper ( 107) length. The slag feeding port ...

Abstract

The present invention relates to an automatic slag-adding device for large-section crystallizer. It is composed of slag hopper, spiral slag-adding pipe, locating buggy for carrying slag hopper, drive motor, controller and touch display screen. The movement of slag hopper on the locating buggy can implement uniform addition of slag for crystallizer. In the course of slag hopper movement the synchronous oscillation of said spiral slag-adding pipe also can be implemented. The controller can be used for automatically regulating slag-adding speed and range according to the crystallizer section, steel quality and billet-drawing speed. The touch display screen positioned on the locating buggy can be used for setting, modifying and displaying parameters of automatic slag-adding device.

Description

technical field [0001] The invention relates to an automatic slag adding device for a crystallizer of a continuous casting machine. technical background [0002] The automatic addition of slag to the crystallizer plays a very important role in ensuring the quality of the billet. There are many ways to automatically add slag to the crystallizer, but the large-section mold usually uses a mechanical type with a slag feeder installed on the steel pouring platform of the continuous casting machine. , for a wider section, a longer slag feeding pipe is required to ensure that the slag at the slag outlet at the end of the slag feeding pipe falls into the crystallizer when the slag feeding pipe swings within a certain angle range. For example, when the section width is 1600mm, the two swinging slag feeding pipes installed in the inner arc of the continuous casting machine are as long as 4.7 meters (NUMTEC-INTERSTAHL GMBH, MOULD POWDERFEEDER for TISCO). Such a long swinging slag add...
