Fixed molten pool smelting furnace manufacturing process

Abstract

The invention provides a fixed molten pool smelting furnace manufacturing process. A fixed molten pool smelting furnace comprises four parts of a furnace bottom, a furnace cylinder, a furnace body anda furnace top. According to the process, the different areas of the smelting furnace are constructed by adopting refractory materials of different materials, melt temperature and scouring of the corresponding areas are adapted, the service life of the smelting furnace is prolonged, ramming materials are smeared on the inner wall of a furnace body water jacket, the furnace body is effectively protected before furnace opening and slag adhering for the first time, the service life of the furnace body is prolonged, according to the furnace temperature and the material of the refractory materials,an expansion joint is reasonably arranged, high-aluminum ceramic fiber paper is laid between a refractory brick and the furnace body, expansion is effectively eliminated, the furnace body is prevented from being damaged, an inner side groove at the joint of the water jacket of the furnace body is blocked by round steel, the outer part is filled with refractory mortar, a corresponding anti-seepagelayer is arranged among layers of refractory materials, furnace leakage and smoke leakage are effectively prevented, the stopping maintenance frequency is reduced, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of smelting equipment, and in particular relates to a manufacturing process of a fixed melting pool smelting furnace. Background technique [0002] With the development of economy and technology, the market's demand for non-ferrous metals has increased. In the face of national energy conservation and emission reduction, small-scale and heavily polluting enterprises have been vigorously rectified. Therefore, increasing production capacity, reducing consumption indicators, reducing production costs, and carrying out large-scale production can enable enterprises to continue to develop. [0003] At present, due to the variety of refractory materials and their different physical and chemical properties, if the expansion is not effectively eliminated during the production process, the lining of the melting furnace will be seriously damaged, the water jacket and shell will be deformed, and the furnace will seep thr...

Problems solved by technology

[0003] At present, due to the variety of refractory materials and their different physical and chemical properties, if the expansion is not effectively eliminated during the production process, the lining of the melting furnace will be seriously damaged, the water jacket and shell will be deformed, and the furnace will seep through the joints of the furnace body. , Smoke leakage, not only affects the overall operating rate of the system but also pollutes the surrounding environment
