Oxygen separating system used for producing steel wooden door metal material

Abstract

The invention discloses an oxygen separating system used for producing a steel wooden door metal material. The oxygen separating system comprises an outer furnace shell, an inner furnace shell and an electric heating layer, a baffle is arranged in the inner furnace shell and internally divides the inner furnace shell into a melting chamber and a refining chamber, a charging pipe is arranged on the outer furnace shell, a connecting pipe, a discharging pipe, a first air inlet pipe, a second air inlet pipe, a second exhausting pipe, a first exhausting pipe and a conveying pipe are arranged outside the outer furnace shell, and a conveying shaft is arranged in the conveying pipe, penetrates through the end face of the conveying pipe to the outer space and is connected with a driving device, and a spiral blade is arranged around the conveying shaft. The feeding mode is improved, a workpiece can be conveyed to the melting chamber while preheated, the refining chamber and a casting box are arranged, mixed gas is introduced into molten aluminum in the refining chamber to remove aluminum oxide and hydrogen in the molten aluminum, the quality of the molten aluminum is improved, and it is ensured that the molten aluminum does not make contact with air in the casting process; the working environment is improved as a tail gas purifying device is further arranged.

Description

technical field [0001] The invention relates to a metallurgical device, in particular to an oxygen separation system used in the production of metal materials for steel and wooden doors. Background technique [0002] As objects that people often come into contact with in daily life, doors and windows not only play the role of shelter from wind and rain, heat insulation, sound insulation, lighting, ventilation, etc., but also an important part of architectural modeling. Their shape, size, color, shape, etc. It has a very important influence on the overall shape of the building. With the improvement of people's living standards, people's demand for doors and windows is increasing, and the requirements for doors and windows are becoming more and more diverse. [0003] Aluminum alloy doors and windows are an important branch of doors and windows. Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan mater...

Problems solved by technology

[0006] The technical problem to be solved by the present invention aims at the shortcomings of traditional melting furnaces, and provides an oxygen separation system for the production of metal materials for steel and wooden doors, which solves the problem of low production efficiency caused by the need for additional preheating furnaces in traditional melting furnaces, and the aluminum liquid contacts air during processing. The problem of low quality of aluminum alloy castings due to lack of refining effect

In the prior art, in order to solve the problem of preheating the workpiece to be melted, a preheating furnace is generally specially set up. The preheating furnace needs to be heated separately, which wastes energy, and after the preheated workpiece is taken out from the preheating furnace, since the workpiece is metal, it will Heat dissipation at a faster speed. The traditional method requires the operator to take out the workpiece from the preheating furnace and put the workpiece into the melting furnace, which reduces the production efficiency. This device improves the feeding method, and can transport the workpiece while preheating. When the workpiece enters The melting chamber has already been preheated in the conveying pipe, which saves process time and reduces the amount of work for workers; As a result, the quality of aluminum alloy castings is low. Even if the follow-up process is advanced, the initial quality defects cannot be eliminated. According to the defects of traditional melting furnaces, this device is equipped with a protective gas, which can be used in the feeding, preheating, melting and casting stages. The workpiece or molten aluminum is isolated from the air. The protective gas during processing is the first protection, and the refining chamber is the second protection. The oxidation in the molten aluminum can be removed by introducing a mixture of chlorine, carbon monoxide and nitrogen into the refining chamber. purpose of aluminum and hydrogen
