Cinder ladle raw material processing method suitable for copper smelting working conditions

Abstract

According to a cinder ladle raw material processing method suitable for the copper smelting working conditions, the flexibility of cinder ladle production raw materials is improved by controlling processing of the cinder ladle raw materials, and therefore the problem that cracks are likely to be generated when cinder ladles are subjected to the high-temperature action for a long time is effectively solved. According to the cinder ladle raw material processing method suitable for the copper smelting working conditions, by means of electric furnace steelmaking and LF furnace refining, the content of harmful elements and residual elements can be effectively reduced, the purity of molten steel is improved, and the content of P and S is smaller than 0.020% and lower than or equal to 0.040% of the national standard. The cracking tendency of the cinder ladle under the high-temperature condition can be effectively reduced. The molten steel is subjected to modification treatment (rare earth re), so that grains can be refined, the physical comprehensive performance of the material can be improved, through single-ladle pouring, on-site temperature measurement is performed before pouring and pouring temperature can be controlled within the range of + / -3 DEG C required by the process, the grains of the slag ladle are relatively uniform and fine, and the physical performance of the slag ladle can be effectively improved.

Description

technical field [0001] The invention relates to a storage device for industrial smelting waste slag, and more particularly relates to a slag ladle raw material processing method suitable for copper smelting working conditions. Background technique [0002] With the sharp increase in the demand for copper for industrial production, the supply of copper resources in my country is becoming increasingly tight, and the copper metallurgy industry is paying more and more attention to the dilution treatment of copper smelting slag. In order to further reduce the copper grade of waste slag, in the past 10 years, the number of domestic enterprises using the grinding float method to realize the slag separation of copper smelting furnaces has been increasing year by year, the scale of slag separation plants has continued to expand, and more and more slag bags have been used. [0003] During the use of the slag bag, when the slag is put into the bag, it is heated to above 700°C instantly...
