Abstract

The invention provides a device for measuring surface tension by using a high-temperature melt maximum bubble method. The device comprises a gas delivery and control system, a heating furnace, a lifting system, an atmosphere control system, a temperature control system and a control system. The gas delivery and control system is used for controlling delivery of the produced bubble gases and acquiring the maximum pressure data; the heating furnace is used for providing a data extraction environment; the lifting system is used for controlling the gas delivery and control as well as a relative position of a measuring object in the heating furnace; the atmosphere control system is used for guaranteeing a reaction atmosphere of the heating furnace; the temperature control system is used for guaranteeing a reaction temperature in the heating furnace; a control display system is used for processing the measured data to calculate the surface tension of high-temperature melt and displaying the tension. According to the device, the surface tension of the high-temperature melt can be rapidly and accurately measured under high temperature rise rate and accurate temperature control.

Description

technical field [0001] The invention belongs to a measuring device, in particular to a device for measuring the surface tension of high-temperature melt physical properties by using the maximum bubble pressure method. Background technique [0002] The surface tension of high-temperature melt is a very important parameter of high-temperature melt, and it is one of the key factors affecting mass transfer and reaction of multi-phase system. For metallurgical slag, especially high-titanium slag, measuring its surface tension has important guiding significance for the cause and control of foaming. [0003] At present, the measurement methods for measuring the surface tension of high-temperature melts mainly include the maximum bubble pressure method, the pulling method, and the static drop method. Among them, the pulling method is the simplest device, but it cannot meet the measurement accuracy requirements. The maximum bubble pressure method was proposed by Simon in 1851, and l...
