Problems solved by technology

Even so, it is also due to the instability of olivine materials, which also limits its development in gunning materials. The alkaline gunning materials on the market are mainly magnesia gunning materials.

Abstract

The invention relates to a synthesized olivine gunning mix and a producing method thereof. The synthesized olivine gunning mix is characterized in that the chemical compositions are: 60 to 70 percent of MgO, 25 to 30 percent of SiO2, 4 to 6 percent of Fe2O3, 0.001 to 2.5 percent of AI2O3, and 0.001 to 2.5 percent of CaO, and the ignition loss is 0.001 to 1.5 percent. The production technologies are material distribution, mixing, inspection and product packaging. The invention has the advantages that: a plurality of raw materials are adopted according to a certain proportion and treated with the procedures of material distribution, mixing, inspection, packaging and the like, thus causing the effective compositions of MgO, SiO2, Fe2O3 and the like to be uniform and have good dispersivity. The integration of common technical skills is adopted and the production technology is simple and convenient and reliable. Furthermore, nitrate, chloride and fluorite and the like which generate harmful gas to the environment and the equipment at high temperature do not exist in the raw materials, and the environment-protection and ecological benefits are good. In addition, the cost of the raw materials is low.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a synthetic olivine gunning material and a production method thereof. Background technique [0002] The olivine minerals commonly found in industrial products are forsterite, fayalite, calcium forsterite and manganese olivine. Forsterite is an island-shaped silicate, which is a kind of olivine mineral. [0003] Olivine group minerals include a group of minerals with similar composition and belonging to the orthorhombic system. The general chemical formula is R 2 [SiO 4 ]express. R 2+ Mainly divalent Mg 2+ , Fe 2+ , Mn 2+ . But when there is Ca 2+ As its composition, a double salt is formed. [0004] Due to the similar radius of divalent positive ions, they can widely form isomorphic series: Mg 2 SiO 4 -Fe 2 SiO 4 -Mn 2 SiO 4 . Among these isomorphic series, the most common in nature are forsterite and fayalite series: Mg 2 [SiO 4 ]-Fe ...
