An automatic adding device for metallurgical exothermic agent for continuous casting final billet

Abstract

The invention discloses a device for automatically adding a metallurgical exothermic agent for continuous casting finishing billets, belonging to the technical field of metallurgical continuous casting equipment. The invention includes a control cabinet, a heating agent silo, a metallurgical heating agent feeding pipe and a nozzle. connected, and the nozzle is located at the edge of the crystallizer; the control cabinet is used to control the addition of the metallurgical heating agent in the heating agent silo to the crystallizer. The present invention adds the metallurgical heating agent into the crystallizer through the automatic adding device, and the whole process is controlled by the control cabinet, so that the metallurgical heating agent is sprayed into the crystallizer from the nozzle along the metallurgical heating agent feeding pipe, and the entire metallurgical heating is controlled The addition time of the agent does not exceed 3 minutes, the whole process requires less human participation, and the degree of mechanization and automation is high. At the same time, it can effectively ensure the performance of the metallurgical heating agent and improve the quality of the casting slab and the yield of molten steel.

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
