Tundish covering agent feeding device and method

Abstract

The invention relates to a tundish covering agent feeding device and a tundish covering agent feeding method. The feeding device comprises a stock bin, a fixed support, a swing mechanism, a rotary support, a motor, a reduction gear, a delivery pipe, a hose, a pitching adjusting mechanism, a delivery pipe flexible adjusting mechanism, a standby position support frame and a charge pipe support, wherein the stock bin is arranged above an operation room of a fixed operation platform; the rear end of the fixed support is fixed on the outside surface of the operation room of the fixed operation platform, and a through hole is formed in the center of the front end of the fixed support; the swing mechanism comprises a rotating shaft, and a U-shaped fixed block is arranged at the upper end of the through hole formed in the center of the front end of the fixed support; the rotary support is located above the fixed support, and the front end of the rotary support is connected with the upper part of the rotating shaft; the motor and the reduction gear are connected with the lower part of the rotating shaft; the delivery pipe is of a foldable structure and comprises first and second straight pipes and a hose; the hose is connected with the stock bin; the pitching adjusting mechanism is used for controlling the delivery pipe to do pitching motion; the delivery pipe flexible adjusting mechanism is used for controlling the delivery pipe to do straightening and folding motion; the standby position support frame is used for supporting the delivery pipe in a standby state, is arranged on the outside surface of the operation room of the fixed operation platform, and is located at one side of the fixed support; and the charge pipe support is arranged on the cover of the tundish.

Description

technical field [0001] The invention relates to a continuous casting process, in particular to a tundish covering agent feeding device and method. Background technique [0002] In the continuous casting process, it is necessary to add a covering agent to the tundish to protect the metal liquid level in the tundish. Different from the addition of mold flux to the continuous casting mold, the input of tundish covering agent is large. The conventional method of adding covering agent is manual bag feeding, and the operator throws the whole bag of covering agent into the hole of the tundish cover by throwing. This method requires the operator to have rich feeding experience, and the work intensity is high. Due to the short distance between tundishes, safety accidents such as molten steel splashing are likely to occur when the operation is inadvertent, and the dust when the covering agent is added is also likely to cause harm to the health of the operators.
