RH-MFB (Rockwell Hardness-Medial Forebrain Bundle) metallurgy reaction simulation test device

Abstract

The invention provides an RH-MFB (Rockwell Hardness-Medial Forebrain Bundle) metallurgy reaction simulation test device which comprises an RH (Rockwell Hardness) furnace vacuum chamber, a steel ladle, a control electric cabinet and a gas supply device, wherein an oxygen lance is connected at the upper part of the RH furnace vacuum chamber; a vacuum meter and a vacuum pump are arranged on a upper pipeline at the RH furnace vacuum chamber; an elevating pipe and a descending pipe are arranged below the RH furnace vacuum chamber respectively; a second alternative current motor drags one end of a screw binding device to be connected to the bottom of the steel ladle, and the other end of the screw binding device is connected to the control electric cabinet; a second electrode and a acidity meter are dipped into the liquid in the steel ladle; the second electrode is connected with a second conductivity ratio meter; the gas supply device comprises an air storage tank and a CO2 storage tank; the input pipeline of the air storage tank is connected with an air compressor; and a second quality flow controller of the output pipeline of the CO2 gas storage tank is connected with the oxygen lance. According to the RH-MFB metallurgy reaction simulation test device, the influence of different operation parameters and production conditions to the circular flowing property of the steel liquid in the RH steel ladle, the mixing property of a metallurgy reactor and the mass transfer property can be researched; and the device can also be used for education.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and relates to RH-MFB vacuum refining technology, in particular to a RH-MFB metallurgical reaction simulation test device. Background technique [0002] RH-MFB multifunctional vacuum refining equipment is the key equipment of the continuous casting and rolling production line. It has opened up broad prospects for the development of high-value-added varieties such as high-quality ultra-low carbon steel series thin plates and expanding market share. The line will play an immeasurable role. Whether it goes straight or not and its efficiency is directly related to whether it can achieve stable improvement of steel quality and high-efficiency and low-consumption production. [0003] The decarburization rate of molten steel in the RH vacuum refining process directly affects the vacuum refining efficiency and the composition of the refining end point, which is of great significance for stably improvi...
