Automatic metallurgical heating agent adding device for continuous casting and collecting tailing billet

Abstract

The invention discloses an automatic metallurgical heating agent adding device for a continuous casting and collecting tailing billet, and belongs to the technical field of metallurgical continuous casting equipment. The device comprises a control cabinet, a heating agent bin, a metallurgical heating agent feeding pipe and a nozzle, the lower end of the heating agent bin is in communication with one end of the metallurgical heating agent feeding pipe, the nozzle is in communication with the other end of the metallurgical heating agent feeding pipe, and the nozzle is located on the edge of a crystallizer; and the control cabinet is used for controlling the metallurgical heating agent in the heating agent bin to be added into the crystallizer. According to the automatic adding device, the metallurgical heating agent is added into the crystallizer, the whole process is controlled by the control cabinet, the metallurgical heating agent is sprayed into the crystallizer from the nozzle alongthe metallurgical heating agent feeding pipe, the adding time of the whole metallurgical heating agent is controlled to be not longer than 3 min, the manual participation amount in the whole processis small, and the degree of the mechanization and automation is high; and meanwhile, the using performance of the metallurgical heating agent can be effectively guaranteed, and the quality of a casting blank and the yield of molten steel are improved.

Description

technical field [0001] The invention relates to the field of continuous casting technology and equipment in the metallurgical industry, and more specifically relates to a device for automatically adding metallurgical exothermic agents for continuous casting finishing blanks. Background technique [0002] The molten steel is poured by the continuous casting machine to form a continuous casting slab. When the current pouring time is about to end, it is necessary to finish the billet work, shut down the main equipment of the continuous casting machine head one after another, and make preparations for the next casting time. In the prior art, the solidification structure state and defects of conventional continuous casting tail billets are as follows: figure 1 shown. After the pouring of the tundish is completed, the liquid level drops as the billet drawing progresses, and the tail billet is pulled out of the crystallizer. Due to the spraying effect of the secondary cooling wat...

Problems solved by technology

However, due to the arbitrariness of adding powder manually, there are lags and differences in judging the timing of adding metallurgical powder manually. The manual control of the continuous adding time of metallurgical powder is not accurate enough, and the adding time may be too long or too short. Phenomenon, and it is not easy to control the entire adding time, which will affect the effect of the final finishing billet, resulting in large defects in the quality of the tailing billet; in addition, it is easy to appear that the amount of addition between different flows is different, resulting in the difference between different tailing billets The quality of the product varies greatly, thus affecting the overall quality of the product

[0004] Therefore, in view of the working process and technical requirements of the continuous casting final billet, it is necessary to invent a metallurgical heating agent automatic adding device, which can overcome the defects of manual work, thereby improving the use efficiency of the metallurgical heating agent for the continuous casting final billet, and solving the problem of tailing billets. quality defects and improve the yield of molten steel
