Abstract

The invention belongs to the technical field of metallurgy, and relates to a runner type online degassing device, which comprises a runner shell, a degassing chamber, gas permeable bricks, a heat insulating cover, a vent, a first baffle plate, a second baffle plate, a middle baffle plate, a gas inlet, an inlet and an outlet; the degassing chamber is arranged in the runner shell; the heat insulating cover is movably connected with the runner shell, and is provided with the vent; two ends of the degassing chamber are provided with the inlet and the outlet; the middle of the degassing chamber is provided with the middle baffle plate; the first baffle plate is arranged between the middle baffle plate and the inlet; the second baffle plate is arranged between the middle baffle plate and the outlet; gaps are reserved between the bottoms of the first and second baffle plates and the degassing chamber; the bottom of the middle baffle plate is fixedly connected with the degassing chamber; the gas permeable bricks are embedded on the bottom of the degassing chamber and arranged between the first baffle plate and the middle baffle plate and between the second baffle plate and the middle baffle plate; and the bottoms of the gas permeable bricks are provided with the gas inlet. The runner type online degassing device has low requirement on space, is provided with the submerged baffle plates and the heat insulating cover, reduces gas absorption again and surface oxidation of degassed aluminium liquid, and has good degassing purification effect.

Description

technical field [0001] The invention relates to a device in the technical field of metal smelting, in particular to a launder-type online degassing device. Background technique [0002] With the continuous development of aluminum alloy applications, the requirements for its inherent quality are also getting higher and higher. Clean melt is the key to ensure the metallurgical quality of aluminum alloy materials. Among the factors affecting the purity of the melt, the precipitation of hydrogen in the melt during the solidification process will lead to defects such as pores and porosity, which is fatal to high-quality aluminum materials, and it not only destroys the internal continuity, reduces the effective cross-sectional area and is the source of cracks. Therefore, degassing plays an important role in the production of high-quality aluminum. [0003] In the aluminum industry, the degassing effect is mainly ensured by the online degassing device outside the furnace, and th...
