Multi-stage leakage-proof refining system based on gas protection

Abstract

The invention discloses a multi-stage leakage-proof refining system based on gas protection and relates to the technical field of refining devices. A refining tank is included. A leakage-proof sealingcover is welded on an upper surface of the refining tank. A feeding hole is welded at an upper end of one side of the refining tank in a penetrating manner. A discharge port is welded at a lower endof one side of the refining tank in the penetrating manner. A fixed plate is welded on one side of the refining tank. A gas tank box is welded on the upper surface of the fixed plate. A purification box is welded to the upper surface of the gas tank box, a gas tank is installed in the gas tank box, a gas inlet pipe is welded to one side of the gas tank box in a penetrating mode, a vacuum pump is installed on the upper surface of the gas tank, an exhaust pipe is welded to one side of the vacuum pump in the penetrating mode, and an access cover is installed on the upper surface of the leakage-proof sealing cover. According to the gas protection refining device, a gas protection structure is small, an exhausted gas can be purified, and due to arrangement of a protection component, molten gasleakage caused by a fact that a temperature of a joint is high is avoided.

Description

technical field [0001] The invention relates to the technical field of refining devices, in particular to a multi-stage leak-proof refining system based on gas protection. Background technique [0002] As we all know, the type, composition and size of non-metallic inclusions in steel often depend on the deoxidation system at the end of smelting. The gas protection device makes the gas transmission inside the device safer and avoids damage to the device due to the high internal pressure of the device. However, most of the gas protection refining devices currently on the market have poor leak-proof effects, resulting in gas escaping, resulting in incomplete reaction with materials and waste of materials. Most of the gas protection devices have large structures and cannot be easily installed on the refining device. , Most of the equipment exhaust can not purify the gas, and most of the connection between the gas protection component and the refining device has no protection com...

However, most of the gas protection refining devices currently on the market have poor leak-proof effects, resulting in gas escaping, resulting in incomplete reaction with materials and waste of materials. Most of the gas protection devices have large structures and cannot be easily installed on the refining device. , Most of the equipment exhaust can not purify the gas, most of the connection between the gas protection component and the refining device has no protection component, which is not conducive to the service life of the device, resulting in the leakage of molten gas at the connection
