Embodiment Construction

[0015] The present invention is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0016] When the vacuum pump system of the refining furnace outside the molten steel RH furnace is not pre-evacuated after the molten steel treatment, the vacuum pumps are all shut down, the main steam valve is closed, and when the vacuum pump system is broken, the steam pressure in the steam drum (steam distributor) will be reduced. Will be transiently elevated and release to the atmosphere will be required.

Abstract

The invention provides a steam releasing method for an RH vacuum pump system steam dome. The method is characterized in that the releasing pipe of a steam dome is connected to the lower part of a condenser. When steam is released, the released steam is introduced into the condenser. The condenser is a third-stage condenser (C3 condenser) which is arranged on a platform near the steam dome. The C3 condenser is sealed and is communicated with condensate water. The upper part of the C3 condenser is provided with an upper sprayer; the middle of the C3 condenser is provided with a middle sprayer; and when released steam airflow is introduced into the C3 condenser, the steam airflow carries out heat exchange with the condensate water sprayed from the middle sprayer and the upper sprayer of the C3 condenser to be condensed into water.

Description

technical field [0001] The present invention relates to a steam release method, and more specifically, the present invention relates to a RH furnace vacuum pump system that reduces noise and releases steam in a safe and harmless manner by introducing steam into a C3 condenser (third-stage condenser) Diffuse method. Background technique [0002] The application of vacuum technology in steelmaking began in 1952. At that time, when people produced silicon steel with a silicon content of about 2%, slag often appeared during the pouring process. After various tests, it was finally found that hydrogen and Atmosphere is the main reason for slag escaping, unable to cast or produce waste products after rolling, and various vacuum refining technologies began to appear, such as vacuum ingot casting method, ladle trickle degassing method, ladle degassing method, etc., thus creating an industrial The emergence of large-scale vacuum treatment methods for molten steel, especially the stea...
