Problems solved by technology

For example: in the process of producing TP2 tube billet, the content of Fe element in the 7-ton melting furnace reaches 150ppm, which is much higher than the international standard of 50ppm. It takes 7-8 hours to wash and dilute the furnace with traditional technology, and the unqualified products are as high as 30-35 Tons, in order to reduce the content of Fe element in the furnace liquid to less than 50ppm, this process will undoubtedly greatly increase the manpower, material resources and financial costs

Abstract

The invention discloses a production method capable of rapidly removing impurities in red copper furnace liquid. The method comprises the following steps that 1, the furnace temperature of a red copper furnace is controlled to be 1190-1200 DEG C; 2, a special covering agent on the surface of the furnace liquid covering in the red copper furnace is fished out, and sampling detection is carried outon the impurity contents of Fe and Zn in the furnace liquid every 8-12 minutes; 3, the special covering agent is added into the red copper furnace for covering adsorption, then TUP14 is then added fordeoxidizing treatment, slag is fished out after an interval of 8-12 minutes, and then the furnace liquid is well covered; 4, sampling detection is carried out on the impurity content of the Fe and the Zn and the content of P in the furnace liquid after an interval of 15-25 minutes, sampling detection is carried out every 8-12 minutes, and sampling is continuously carried out twice; and 5, the twosampling detection results are compared, and if the decrease value of the content of the P in the furnace liquid is less than 40ppm, in addition, the impurity contents of the Fe and the Zn are less than 20ppm, the components of the furnace liquid are qualified. Compared with a traditional process method, the production method has the advantage that cost of manpower, material resources and financial resources can be greatly lowered.

Description

technical field [0001] The invention relates to the technical field of impurity removal technology, in particular to a production method for rapidly removing impurities from copper furnace liquid. Background technique [0002] In the process of producing TP1 / TP2 / T1 / T2 / TU1 / TU2 and other copper pipe and wire products, due to impurities in raw materials or improper operation, the impurities such as Fe and Zn in the copper furnace liquid exceed the standard. The traditional way to remove impurities such as Fe and Zn in the copper furnace liquid is to wash the furnace and dilute it. For example: in the process of producing TP2 tube billets, the content of Fe element in the 7-ton melting furnace reaches 150ppm, which is much higher than the international standard of 50ppm. It takes 7-8 hours to wash and dilute the furnace with the traditional process, and the unqualified products are as high as 30-35 tons, in order to reduce the Fe element content in the furnace liquid to below 5...
