Amorphous thin strip tundish molten iron metering and control system

Abstract

The invention discloses a tundish liquid iron metering and controlling system for amorphous thin strips. The tundish liquid iron metering and controlling system comprises a tundish system, a strip spraying pocket system and a computer control system. The tundish system comprises a tundish, a tundish cover, a tundish frame and a sensing coil, the tundish cover is arranged on the top of the tundish, the tundish is fixed by the aid of the tundish frame, the sensing coil is arranged on the tundish, the tundish frame is erected on a travel support, a weighing sensor is arranged at erection positions of the tundish frame and the travel support, a temperature sensor and a first stopper rod are arranged on the tundish cover, the temperature sensor extends into the tundish, a liquid iron flow guide groove which is communicated with an inner cavity of the tundish is formed in the tundish cover, the first stopper rod is connected with a stopper rod driving device, a bottom runner is arranged at the bottom of the tundish, a nozzle seat is arranged at the bottom of the bottom runner, and the tail end of the stopper rod is fittingly connected with the nozzle seat; the strip spraying pocket system comprises a spraying pocket shell, an upper spraying pocket and a lower spraying pocket, the upper spraying pocket and the lower spraying pocket are arranged in the spraying pocket shell in a serially connected manner in the up-down direction, and a spraying pocket cover is arranged on the top of the upper spraying pocket.

Description

technical field [0001] The invention relates to a measurement and control system for molten iron in a tundish of an amorphous thin strip. Background technique [0002] Amorphous alloy thin strip is a new type of high-efficiency and energy-saving material. Its key technology has been monopolized by Hitachi Metals for many years, and the technology and production equipment are very blocked. The measurement and control of molten iron in the production of complete sets of equipment is also the key to the quality of the spray belt. technology. The pressure generated by the liquid level height of the spray ladle will affect the flow velocity of the nozzle molten iron, and the instability of the nozzle molten iron flow velocity will directly cause the thickness of the sprayed thin strip to be uneven, so the liquid level accuracy of the spray ladle is ensured. Will guarantee the quality of strip products, the prior art does not have the introduction of molten iron metering and cont...

AI Technical Summary

Problems solved by technology

The pressure generated by the liquid level height of the spray ladle will affect the flow velocity of the nozzle molten iron. The instability of the nozzle molten iron flow velocity will directly cause the thickness of the sprayed thin strip to be uneven. Therefore, to ensure the liquid level accuracy of the spray ladle, It will ensure the quality of thin strip products. There is no introduction of molten iron metering and control system in the prior art, and further improvement is needed.
