A kind of converter tap hole installation device and tap hole installation method

Abstract

The invention discloses a converter steel tapping hole installation device which comprises a connecting plate, an oil cylinder, an oil cylinder support seat, an oil cylinder connecting handle, an oil cylinder connecting handle pin, a connecting piece, a U shaped shackle, an anchor chain, a hook, a steel tapping hole installation plate and a crowbar. A converter steel tapping hole installation method is as follows: the steel tapping hole installation plate is mounted to a steel tapping hole, a plurality of refractory brick heel blocks are arranged under a steel tapping hole abdominal brick, the steel tapping hole is lifted to a steel tapping hole seating brick inner cavity, the steel tapping hole installation plate is pushed to close to a connection plate; a steel tapping hole lining pipe sleeve penetrates into the steel tapping hole from the tail part; the steel tapping hole installation plate geometric center is provided with a hole; a driving oil cylinder pulls up one ends of the steel tapping hole installation plate and the steel tapping hole, and the lower parts are suspended in the air; and the steel tapping hole installation plate and the connection plate are tightly fitted. According to the converter steel tapping hole installation device and method, quick and accurate installation of the steel tapping hole is realized, he'' steel running '' risk and labor intensity are reduced, and the replacement efficiency of the steel tapping hole is improved.

Description

technical field [0001] The invention relates to steelmaking machinery, in particular to a taphole installation device and a method for installing a taphole of a converter. Background technique [0002] During converter steelmaking, the tap hole of the converter is scoured by the metal liquid, so its lifespan is limited and it is difficult to replace it. After the tap hole has reached its service life, the original tap hole needs to be bored out and a new tap hole installed. It is difficult to control the roundness and angle of the hole when the boring machine is boring. In addition, the gravity of the tap hole itself is large and the use of tools is limited. The installation is extremely inconvenient, so that the installation quality of the tapping hole cannot be effectively controlled, and the upper surface of the nozzle brick in the tapping hole cannot meet the flatness requirements, resulting in an increased risk of "steel running" between the slag gate valve mechanism an...

[0002] During converter steelmaking, the steel outlet of the converter is scoured by the metal liquid, so the service life is limited and it is difficult to replace

After the tap hole has reached its service life, the original tap hole needs to be bored out and a new tap hole installed. It is difficult to control the roundness and angle of the hole when the boring machine is boring. In addition, the gravity of the tap hole itself is large and the use of tools is limited. The installation is extremely inconvenient, so that the installation quality of the tapping hole cannot be effectively controlled, and the upper surface of the nozzle brick in the tapping hole cannot meet the flatness requirements, resulting in an increased risk of "steel running" between the slag gate valve mechanism and the connecting plate, and frequent accidents; operation The intensity of personnel is high and the efficiency is slow, which cannot meet the fast-paced requirements of converter steelmaking production, which will directly affect the downstream continuous casting production of the steel plant, resulting in large economic losses
