Problems solved by technology

Because the method of human observation is not very accurate, the surface pressure between the slides is unstable; moreover, because they are all pressurized parts as a whole, it is easy to produce gaps in the combination at high temperature due to excessive thermal deformation, so that the mechanism is in the output. During the steel process, there are often cases of uneven pressure on the surface of the slide plate and steel penetration, and even accidents of burning through the mechanism, which seriously affect the tapping production

Abstract

The invention discloses a sliding block type converter tapping hole sliding plate slag stopping device. A sliding frame is arranged between a fixed frame and a pressing frame, and is matched with a sliding groove of the fixed frame in a sliding manner; a fixed nozzle brick is fixed in the fixed frame, and a sliding nozzle brick is arranged on the sliding frame; spring pressing components are arranged on the pressing frame, and are used for pressing the sliding nozzle brick on the fixed nozzle brick by virtue of the sliding frame. By adopting the technical scheme, a plurality of groups of independent and uniformly-distributed spring pressing components and sliding bars are used for forming a pressing mode that a plurality of points are in elastic contact so as to ensure that stable and uniform surface pressure can be generated between nozzle bricks of the sliding plate, and generation of the steel leakage phenomenon can be prevented. The sliding block type converter tapping hole sliding plate slag stopping device is reasonable in structure, good in interchangeability, convenient in disassembly, simple in operation and safe and reliable in use.

Description

technical field [0001] The invention belongs to the technical field of steelmaking process produced in the metallurgical industry, and in particular relates to a sliding block type converter tapping hole sliding plate slag retaining device. In addition, the present invention also relates to the pressing method of the slide plate in the device. Background technique [0002] Sliding plate slag blocking is a new type of slag blocking technology in converter steelmaking production. [0003] In the prior art, most commonly used sliding plate slag retaining mechanisms at the taphole of the converter adopt the method of bolt compression, and the sliding fit is combined into two types: roller-slideway type and slideway-slideway type, and the pressure is transmitted through the entire spring bead , so that surface pressure is generated between the skateboard bricks. However, when these types of mechanisms are maintained and installed, the method of manually watching the scale is us...
