Description
Technical Field
[0001] The present invention relates to the technical field of synthetic furnace equipment, and specifically relates to a rotary anode synthetic furnace for producing copper-nickel anode plates. Background Art
[0002] Currently, the pyrometallurgical smelting of solid copper-nickel matte containing copper, nickel, tin, etc. includes two steps: blowing and pyrometallurgical refining, which are completed in different smelting furnaces. For example, blowing mostly uses a PS converter, and pyrometallurgical refining mostly uses a reverberatory furnace, a rotary furnace, etc. The high-temperature melt containing copper and nickel produced by blowing is added to the refining furnace through a traveling crane and a ladle, and finally cast into copper-nickel anode plates. The high-temperature process flue gas generated by the two furnaces needs to be treated by respective supporting flue gas treatment systems. The blowing slag or refining slag produced by the two furnaces is cooled separately. The cooled blowing slag is sent to the slag selection system, and the refining slag is sent to the slag recovery system.
[0003] The current process flow is long, the investment is large, and the floor area is large. The high-temperature molten materials containing copper and nickel are transported by a traveling crane between the two furnaces and in the workshop, which not only increases the operation time but also reduces the low heat utilization efficiency.

[0022] As Figure 3 shown, in this solution, the rotary anode synthesis furnace further includes furnace body software. The furnace body software includes a synthesis furnace control module, a production process management module, a materials and equipment verification module, and a power management module. The synthesis furnace control module, the production process management module, the materials and equipment verification module, and the power management module are all provided inside the control panel and are respectively communicatively connected to the control panel.

[0023] The furnace body software further includes a furnace body heating system: an efficient electric heating system or a gas heating system is adopted to ensure uniform temperature inside the furnace. The temperature inside the furnace is monitored in real time through a temperature sensor and adjusted through an automatic control system to ensure that the temperature during the synthesis process is within the optimal range.
[0024] The furnace software also includes an airflow control system: the uniform distribution of airflow in the furnace is crucial to the uniform fusion of the alloy. The Zhuanyang synthesis furnace is equipped with a rotating airflow system, which adjusts the direction and speed of the airflow to evenly distribute the heat and material in the furnace, thereby achieving uniform alloy composition and good synthesis effect.
[0025] like Figure 1-Figure 3 As shown, in this scheme, the production process of copper-nickel anode plates produced by using a positive conversion synthesis furnace is as follows: Step 1: Prepare the required raw materials in advance: solid copper-nickel matte, quartz stone, and coke powder are sent to the furnace side silo for batching. After the batching is completed, they are sent from the furnace mouth 5 to the positive synthesis furnace through the furnace top feeding device. The main components of the solid copper-nickel matte are Cu 30%, Ni 4%, S 22%, Fe 25%, and Sn 1%; Preparation method of solid copper-nickel matte in step 1: Raw material selection: First, select Cu and Sn as the main raw materials. According to the composition requirements of the target alloy, weigh the required weight of raw materials; Melting furnace selection: Use electric furnace or induction furnace for melting, which provides a stable high temperature environment and helps to fully mix copper and nickel; Melting temperature control: put Cu and Sn into the melting furnace according to the required proportion, heat the temperature to 1300°C-1600°C, and heat for 2-5 hours to ensure that the metals are fully melted and mixed. During the melting process, add the required weight of Fe and S to improve the properties of the alloy; Casting process: The molten copper-nickel alloy liquid is poured into the mold and cooled to obtain a rough billet. The alloy billet after casting needs to be cut and trimmed, and further processed by forging. The temperature is 900°C-1200°C, and it is kept heated and forged for many times; Cooling annealing: After the forging and rolling process, the alloy needs to be slowly cooled, the cooling time is 3-7h, the annealing temperature is 600°C-900°C, and the cooling time is 1-2h; Use spectral analysis, chemical analysis and other methods to ensure that the composition of the alloy meets the design requirements. At the same time, the surface of the copper-nickel alloy is electroplated, sprayed and other treatments are performed to obtain the final product, which is used in conjunction with step 1.
[0026] Step 2: Blow oxygen and natural gas into the furnace through the combustion burner 8, use natural gas as fuel to melt the cold material, use full oxygen combustion technology to reduce fuel consumption, add materials into the furnace from the furnace port 5 in batches, and cut off the air and oxygen supply of the burner after all the cold materials are melted; Step 3: oxygen-enriched air is blown in from the tuyere 2 at the rear of the furnace to form slag. The end point of the slag forming reaction is determined by the fluidity and appearance color of the slag and the content of copper-nickel alloy is tested by sampling. After the reaction is completed, the air supply is stopped and most of the impurity metals are oxidized into the blowing slag and poured into the slag bag from the furnace port 5; Step 4: Continue to blow in oxygen-enriched air through the tuyere 4 behind the furnace to make copper-nickel. During the copper-nickel making period, the copper-nickel matte remaining in the furnace reacts with the oxygen in the blown oxygen-enriched air to form a copper-nickel alloy. After the copper-nickel alloy is formed, some cold materials such as crude copper can be added to make full use of the excess heat in the furnace. Samples are taken to detect the S content in the copper-nickel alloy. When it is lower than the set threshold, the surface roughness and color of the liquid alloy in the furnace are observed as a basis for judging the end point of the copper-making period. Step 5: After the oxidation operation is completed, the furnace pressure is adjusted to a slightly positive pressure, and refining reduction is performed. A reducing agent is introduced to reduce the oxidized copper-nickel to obtain a copper-nickel alloy. The reduction end point is determined by the surface roughness and color of the liquid alloy. The reducing agent is sprayed from the reduction port 1 in front of the furnace to maintain a reducing atmosphere in the furnace; Step 6: The high-temperature liquid copper-nickel alloy flows into the tundish through the chute, and is automatically and quantitatively cast into copper-nickel anode plates of qualified shape and weight by a single disc casting machine, and then transported to the yard by a forklift. The main components of the copper-nickel anode plates are Cu 81%, Ni 7.7%, and Sn 0.13%.
[0027] The converter synthesis furnace invented this time solves the problems of not being able to supplement heat, reduce and refine in the blowing furnace, and not being able to be directly cast into plates. The traditional converter is modified by adding a combustion burner at one end of the furnace body, through which fuel can be sprayed for combustion to supplement the heat in the furnace; a reduction port is added in front of the furnace, through which a reducing agent can be sprayed into the furnace for reduction and refining; a copper-nickel outlet is set at the other end of the furnace body opposite to the burner, through which copper and nickel can be directly discharged, and directly cast into copper-nickel anode plates through a chute to a disc casting machine. At the same time, the blowing and refining processes are completed in one furnace, seamlessly connected, which can shorten the process flow, reduce heat loss in the furnace, heat loss of high-temperature melt, and also reduce low-altitude pollution.
[0028] The present invention realizes the blowing and refining process of solid copper-nickel matte in the same furnace, shortening the process flow. At the same time, since the crane reverse transportation of hot molten body is omitted, the problems of heat loss and low-air pollution in the transportation process are solved, the operation efficiency and operation safety are effectively improved, the investment and production cost are reduced, and the invention has the advantages of short process, low investment, low energy consumption, high environmental protection and high efficiency, and continuous process.
[0029] The present invention is provided with furnace hardware and furnace software for use together, which makes it convenient for staff to control the entire furnace on site and remotely, thereby improving the flexibility of equipment use and the overall intelligence level. When problems and abnormalities occur in one of the equipment or processing links, they can be located in the first time and handled accordingly, reducing unnecessary losses.
