Production system for steel wooden door metal raw material

Abstract

The invention discloses a production system for a steel wooden door metal raw material. The production 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 divides the internal part of the inner furnace shell into a melting chamber and a refining chamber, a feeding pipe is arranged on the upper portion of the outer furnace shell, the outer side of the outer furnace shell is provided with a connecting pipe, a discharging pipe, a first gas inlet pipe, a second gas inlet pipe, a second exhaust pipe and a first exhaust pipe, the connecting pipe is communicated with the melting chamber and the refining chamber, the discharging pipe is communicated with a casting box and the refining chamber, the first gas inlet pipe is communicated with an external space, the melting chamber and the refining chamber, the second gas inlet pipe is communicated with the external space and the refining chamber, and the first exhaust pipe is communicated with the external space and the melting chamber. According to the production system, the refining chamber and the casting box are arranged, the purpose of removing aluminum oxide and hydrogen in molten aluminum is achieved by introducing mixed gas into molten aluminum contained in the refining chamber, and the molten aluminum quality is improved; in addition, a tail gas purifying device is arranged, and therefore the working environment is improved; it is guaranteed that molten aluminum cannot make contact with air in the casting process through the casting box.

Description

technical field [0001] The invention relates to a metallurgical device, in particular to a production system for metal raw materials of 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 materials. Aluminum alloy doors...
