Description
Technical Field
The invention belongs to the field of high-temperature structural materials, and particularly relates to a preparation method of a silica crucible for an induction furnace lining.
Background
Induction furnaces have been widely used in industrial production as melting equipment for melting high temperature alloys and special alloys because of their advantages of high melting speed, high temperature of the molten metal, uniform chemical composition, etc. The furnace lining is one of the important components of the induction furnace, not only plays a role of supporting a container, but also participates in the metallurgical physical and chemical reaction processes, and has important influence on the safe and stable operation of the intermediate frequency induction furnace and the quality of steel. Because the operating temperature of the alloy is high in the smelting process, the furnace lining is in a complex and severe working environment for a long time, and the high-temperature liquid is subjected to the scouring of the inner wall and the erosion of slag for a long time, so that the service life of the alloy is shortened, and the quality of the melt is reduced. Therefore, the selection of furnace lining materials and the preparation process directly influence the service life and the generation efficiency of the induction furnace. At present, corundum crucibles, magnesium crucibles and the like are generally used as lining materials of induction furnaces, and although the corundum crucibles, the magnesium crucibles and the like have the characteristics of high refractoriness, stable chemical properties and high strength, the anti-corrosion effect is not ideal in the repeated use process under the harsh smelting environment, and the furnace body needs to be further improved in use. Therefore, the method for preparing the high-performance induction furnace lining material is always concerned by domestic and foreign enterprises.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a preparation method of a siliceous crucible fired by silicon for an induction furnace lining, which has good strength and excellent thermal shock resistance and erosion resistance.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a preparation method of a silicon sintering crucible for an induction furnace lining is characterized by comprising the following steps:
(1) crushing high-quality silica mined in a mine to obtain a silica block material;
(2) sieving the silica block to obtain materials with particle sizes of 8-6mm, 5-4mm, 3-2mm, 1-0.074mm and below 200 meshes;
(3) mixing 15-25% of material with the granularity of 8-6mm, 15-25% of material with the granularity of 5-4mm, 15-25% of material with the granularity of 3-2mm, 15-25% of material with the granularity of 1-0.074mm, 20-30% of material with the granularity of less than 200 meshes and 2-5% of binding agent for 5-30min by mass percentage to obtain mixed material;
(4) placing the mixed material into a mold, and performing mechanical pressing molding at the pressure of 100-300MPa to obtain a molded blank body;
(5) drying the formed blank at the temperature of 100-200 ℃ for 24-40h to obtain a dried formed blank;
(6) and (3) firing the dried and molded blank at the temperature of 1400 ℃ and 1450 ℃ for 5-10h, and naturally cooling along with the furnace to obtain the siliceous firing crucible.
SiO in the high-quality silica in the step (1)2The content is more than 98 percent.
The binding agent in the step (3) is lime milk with the concentration of 20-50%.
The mixing equipment in the step (3) is a wet mill or a high-speed mixer.
The forming equipment in the step (4) is a single-shaft pressing brick machine or an isostatic pressing machine.
In the process of preparing the lining material of the siliceous sintering crucible, quartz can generate complex polycrystalline transformation, and the residual expansion can cause the joint cutting to be tightly adhered along with volume expansion, thereby ensuring that the material has good air tightness and bonding strength. The main crystal phase of the quartz in the material is tridymite which has a spearhead-shaped double-crystal interlaced network structure, and the thermal shock resistance and the mechanical strength of the product can be effectively improved. Meanwhile, a certain amount of bonding agent is introduced to promote the formation of tridymite phase, inhibit the quantity of cristobalite and residual quartz phase, and prevent the phenomena of product loosening and cracking in the sintering process.
Compared with the prior art, the invention has the beneficial effects that: the furnace lining material of the siliceous sintering crucible has low impurity content, obviously improves the anti-erosion capability of the furnace lining material in the smelting process, effectively prevents high-temperature melt from scouring the furnace lining material and slag, prolongs the service life of an induction furnace, greatly improves the thermal shock resistance of the material, ensures that the product quality is more stable and reliable, realizes long-term stable production operation in the furnace, improves the working efficiency and increases the enterprise profit.
