Embodiment Construction
[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0027] The steam discharge of the existing secondary cold room 1 of continuous casting uses a high-power motor to directly drive the fan device, which has problems such as large power consumption, high installation requirements, and high maintenance costs. In order to solve the above problems, the venturi tube steam exhaust device 4 and the waste heat steam pipeline 5 of the existing converter or electric furnace smelting in the production workshop are used to discharge the steam in the second cold room of continuous casting.
[0028] combine figure 1 , figure 2 As shown, the present invention provides a preferred embodiment of an energy-saving and environment-friendly ...

The invention relates to the field of metallurgical steelmaking continuous casting, in particular to an energy-saving and environment-friendly continuous casting machine secondary cooling chamber steam exhaust device and method. The energy-saving and environment-friendly continuous casting machine secondary cooling chamber steam exhaust device comprises a secondary cooling steam pipeline and a Venturi tube steam exhaust device, the secondary cooling steam pipeline is connected with a continuous casting machine secondary cooling chamber and the Venturi tube steam exhaust device, and the Venturitube steam exhaust device is connected with a waste heat steam pipeline. The invention further provides the steam exhaust method adopting the energy-saving and environment-friendly continuous castingmachine secondary cooling chamber steam exhaust device. Steam generated in the continuous casting machine secondary cooling chamber flows into the secondary cooling steam pipeline, the Venturi tube steam exhaust device is connected to the secondary cooling steam pipeline, waste heat steam is introduced into the Venturi tube steam exhaust device through the waste heat steam pipeline, a negative pressure zone is formed, and the steam in the secondary cooling steam pipeline is sucked by the negative pressure zone. According to the energy-saving and environment-friendly continuous casting machinesecondary cooling chamber steam exhaust device and method, energy consumption is low, the cost is low, and the structure is simple.
Description
technical field [0001] The invention relates to the field of metallurgical steelmaking and continuous casting, in particular to an energy-saving and environment-friendly secondary cooling room steam discharge device and method of a continuous casting machine. Background technique [0002] The continuous casting process is a production process of continuously casting high-temperature molten steel into billets with a certain cross-sectional shape and a certain size specification. To complete this process, a complete set of continuous casting equipment is required. Steel casting equipment, continuous casting machine body equipment, and cutting areas Equipment, conveying equipment, etc. constitute the core equipment of continuous steel casting, generally called continuous casting machine. [0003] Among them, the water vapor in the secondary cooling chamber of the continuous casting machine is formed after the molten steel in the tundish is injected into the crystallizer, and th...
