Embodiment Construction

[0052] The present invention will be described in further detail below.

[0053] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "horizontal", "inner", "outer", etc. is based on the orientation or position shown in the drawings The relationship is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implici...

Abstract

The invention relates to a comprehensive measurement device used for measuring the sulfur capacity of slag and the melting characteristic. The comprehensive measurement device comprises a heating furnace, an atmosphere control system, a temperature control system, a melt melting characteristic measurement system and a control display system; a sample is put into the heating furnace to react; the atmosphere control system is used for controlling the reaction atmosphere in the heating furnace; the temperature control system is used for controlling the reaction temperature of the sample in the heating furnace; the melt melting characteristic measurement system is used for measuring the melting characteristic of the sample in the heating furnace; and the control display system is used for calculating the oxygen partial pressure PO2 and the sulfur partial pressure PS2 according to the air flow measured by the atmosphere control system, and calculating the sulfur capacity of the slag according to the formula in the description. The comprehensive measurement device not only can be used to measure the sulfur capacity of the slag through slag-air balance, but also can be used to measure the melting characteristic of a melt.

Description

technical field [0001] The invention relates to a metallurgical process testing instrument, in particular to a comprehensive device for measuring the sulfur content and melting characteristics of molten slag. Background technique [0002] The sulfur capacity and melting characteristics of high-temperature slag are very important properties of high-temperature slag, which have an important impact on desulfurization in the metallurgical process, the smooth operation of the furnace and the improvement of product quality. At present, the experimental devices for measuring the sulfur content of slag mainly include the preparation atmosphere device and the horizontal heating furnace. The experimental device for measuring the melting characteristics of the melt mainly consists of a horizontal heating furnace and an independent video imaging device. At present, there is no connection between these two measurement devices, and it is extremely inconvenient to use. Therefore, a device...
