Problems solved by technology

[0002] At present, the vacuum furnace for sintering manganese zinc ferrite materials has the problems of low output, high energy consumption, long cycle time and poor product performance consistency
However, the bell furnace also has the problems that the sintering process relies on the continuous supply of nitrogen and the uneven temperature distribution and product consistency deviation caused by too fast airflow.

specific Embodiment approach

[0039] Manganese-zinc ferrite power powder is pressed into EE30 blanks, stacked on 340X340X12mm sandwich setter boards, 325 pieces are stacked on each board, and the four corners of each setter board are supported by corundum pillars, chopped into a stack of 20 boards each. There are four stacks in one furnace. A total of 26,000 pieces. Each weighs 12.5g, totaling 325kg. After the four stacks are installed, the furnace door is closed.

[0040] Start the electric control cabinet switch, open the fan 2, the first valve 4, the fourth valve 7, and the second valve 5. Start heating up. Depending on the temperature, the air supply volume of the fan is different. The fresh air enters from the fan 2, passes through the first valve 4, the heat recovery device 10, and the fourth valve 7, and is divided into two routes: the first air inlet 12 and the second air inlet. 17 enters the furnace body 16, and the waste gas is discharged from the gas outlet 15 at the top of the furnace body ...

Abstract

The invention relates to a Mn-Zn ferrite sintering furnace, which comprises a furnace body, a heat energy recovery, a cooler, a condenser, an electrical control cabinet, a pump and a fan and the like, wherein the upper portion of the furnace body is provided with a gas outlet, the side surface of the furnace body is orderly provided with a gas inlet, a nitrogen and oxygen mixed gas inlet, a vacuum pump interface and an interface which is connected with the electrical control cabinet, the fan is orderly connected with the heat energy recovery and a fourth valve through a first valve, the fourth valve is divided into two circuits to connect with a first gas inlet and a second gas inlet of the furnace body, the other end of the heat energy recovery is connected with the gas outlet through the cooler, and a pipeline arranged between the heat energy recovery and the cooler is connected with a condenser. The Mn-Zn ferrite sintering furnace has the advantages of high purity nitrogen conservation, energy conservation and low manufacturing cost, and is an ideal device for meeting the demands of development of integrated small batch production of Mn-Zn ferrite materials.

Description

technical field [0001] The invention belongs to the field of industrial kilns, and in particular relates to a manganese-zinc ferrite sintering furnace and a sintering process thereof. Background technique [0002] At present, the vacuum furnace for sintering manganese zinc ferrite materials has the problems of low output, high energy consumption, long cycle time and poor product performance consistency. The bell furnace also has the problems of insufficient sintering process relying on continuous supply of nitrogen and uneven temperature distribution and product consistency deviation caused by too fast airflow. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a manganese-zinc ferrite sintering furnace and a sintering process thereof, which can save high-purity nitrogen, reduce energy consumption and manufacture cost. [0004] The present invention adopts following technical scheme to realize: [0005] A ma...
