Abstract

The invention discloses a method for predicting high-temperature viscosity and wire drawing temperature of basalt melt through viscosity modulus. The method comprises the following steps: determiningthe viscosity modulus of each component in a basalt raw material according to the mole percentage of the component; predicting the viscosity of the basalt melt at each high-temperature point accordingto the viscosity modulus; further obtaining a prediction formula of the viscosity of the basalt melt at any temperature point within the range of 1250-1550 DEG C; and defining the wire drawing temperature as the temperature at which the melt viscosity is 318 dPa.s, so that the wire drawing temperature can be solved. According to the method, the accurate prediction of the high-temperature viscosity of the basalt ore and the wiredrawing temperature can be simply, conveniently and quickly predicted, and compounding of basalt raw materials can be quickly realized; basalt ore which is originally not suitable for producing continuous basalt fibers can be continuously used after viscosity optimization, and the problems that in the prior art, high-temperature viscosity testing of basalt consumestime and labor, the wire drawing temperature is manually set according to experience, and product quality improvement and stability control are not facilitated are solved.

Description

technical field [0001] The invention relates to the field of basalt wire drawing preparation, in particular to a method for predicting high-temperature viscosity of basalt melt and wire drawing temperature through viscosity modulus. Background technique [0002] Basalt is the most important component of the earth's oceanic and continental crust, and it is also a mineral resource widely distributed on the earth's surface. It has extremely important research and application values. Continuous basalt fiber is made of volcanic rocks such as basalt, diabase and gabbro as raw materials. It is ground to a certain fineness, then continuously melted at high temperature, and finally drawn quickly through a bushing plate made of high temperature resistant platinum-rhodium alloy material. A continuous fiber material. Because of its good flame retardancy, high temperature resistance, acid and alkali resistance, low hygroscopicity, and excellent mechanical properties, continuous basalt f...
