Abstract

The invention discloses a process for producing a fluorite ball. The process comprises the following several steps of (1) raw material treatment: placing fluorite floatation powder into a drying box for drying, wherein the granularity of the fluorite floatation powder is 200 meshes, the drying temperature is 100-120 DEG C, and the temperature inside the drying box is 600 DEG C; (2) feeding: feeding the fluorite floatation powder into a stirring tank through a pit conveying belt, stirring and adding an additive at the same time, sufficiently stirring to obtain a mixture, wherein the additive comprises clay, sodium silicate and calcium stearate, and the weight ratio of the fluorite floatation powder to the additive is 10:1; (3) extrusion: placing the mixture into an aluminum semisphere press mould, and oppositely pressing and extruding by adopting a hydraulic pump to obtain a fluorite ball crude product; and (4) secondary drying: carrying out the secondary drying on the fluorite ball crude product under the condition that the temperature is 105-120 DEG C to obtain a final fluorite ball finished product, wherein the drying time is 40-60 minutes.

Description

Technical field: [0001] The invention relates to a co-solvent in metallurgy, in particular to a production process of fluorite balls. Background technique: [0002] Fluorite is widely used in the metallurgical industry. It can lower the melting point of refractory substances, promote the flow of slag, separate the slag and metal well, improve the desulfurization and dephosphorization process in the smelting process, and enhance the malleability and properties such as tensile strength. Therefore, it is widely used as a flux in iron and steel smelting and ferroalloy production, ferrochemical process and non-ferrous metal smelting. China is a big producer of fluorite products as well as a big consumer. At present, fluorite lump ore resources are few and of low grade. Domestic fluorite lump ore production is decreasing year by year, and the domestic fluorite lump ore market has a large gap. In recent years, the grade of fluorite lump ore supplied to domestic steelmaking is l...
