Abstract

The invention relates to the technical field of converter slag stopping, and discloses a converter slag stopping device capable of being quickly replaced online. The converter slag stopping device comprises a fixing plate, wherein an oil cylinder is fixedly arranged on the side wall of the upper end of the fixing plate, and a positioning block is fixedly connected to an output shaft at the lower end of the oil cylinder; a slag stopping plate is slidably connected to the front side of the fixing plate, and two clamping blocks which are symmetrically arranged about the positioning block are fixedly connected to the upper end of the slag stopping plate; the front side of the fixing plate is symmetrically and fixedly connected with two L-shaped limiting plates which are connected to the outerside of the slag stopping plate in a pressed mode; the positioning block is of a hollow structure, a through hole is formed in the front side of the positioning block, and a rotary drum is rotatably connected into the through hole in a sleeved mode through a ball bearing; an extension rod is movably inserted into the rotary drum in a sleeved mode; and a same thrust spring is fixedly connected between the end, located in the rotary drum, of the extension rod and the bottom of the rotary drum. The slag stopping plate can be rapidly mounted and limited, and the use efficiency of converter slag stopping is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of converter slag blocking, in particular to a converter slag blocking device that can be quickly replaced online. Background technique

[0002] The sliding plate slag blocking method is to install a set of compact and durable sliding plate slag blocking gate valve device on the outer end of the converter tapping hole, and open or close the tapping hole mechanically, so as to realize the purpose of avoiding slag during tapping. The slag blocking effect of the skateboard slag blocking process is stable, and the success rate can basically reach 100%. It realizes the full control of the slag in the early stage of converter tapping and quickly prevents the slag in the later stage at the first time. The thickness of the slag layer of the ladle under the furnace can be stably controlled below 50mm, and it also prevents the steel slag from overflowing again when the furnace is lifted after tapping. It realizes cle...
