High alumina bauxite in the Medium Frequency Induction Furnace

9 (2 。。。),moncler daunenjacke。 I one. . 58 a. 】 Af. Wide spread bark acidic medium frequency induction furnace lining for the life span of only about 20 heats the densification of sintered bauxite lining. I3 Q; Yan Xiao G 406 a 0: z furnace building, oven technology 『} {/『 fighting years production practice proves, its life of up to ~ heats and set a B \., a poor connection with 2 5 0. m. the layers of the smiling full cage: a short high temperature sintering process, as in: Die Pi Chart: 24h? 'wife next limonene Kettle: Xin Lei crucible like to write enhanced Yin The selection of a high performance cost Lvfan means: in practice in the production, content found in some cases A10,ugg prezzo, Fe0. Lining the content of life and directly affect the lining of the surface roughness. When Feo: content is too high the one hand, the surface lining caused by scarring, the smaller volume of the crucible; addition, reducing the lining slag erosion of antioxidant capacity, increased insecurity in the lining. Therefore, when the melting alloy. Al0 high-alumina in addition to controlling the content, must be strictly controlled Fe0 content of the specified range. 12 particle size ratio in order to obtain low porosity and high thermal shock resistance of the crucible size ratio must be selected (see Table 2) Table 2 alumina particle size alumina smelting alloy steel binder ratio of 1.3 AIO. a high purity SiO,moncler outlet, to reduce the sintering temperature by adding boric acid of 1.2 to 1.5 for industrial adhesives. sintering temperature is generally 1450 ~ 1550C. boric acid in the heating process, generate B: 0, melting at around 570C, from the bonding role in promoting high-cycle 1150kg baking furnace burning in the mantis technique Po 3 'lining maintenance and repair occurs when the lining Results scar, the time of the parts with the drill rod knock down the furnace. remove residual liquid metal, well with a little boric acid and water to wet the patched place. and then after the three particle size furnace building materials, repair and high-alumina ramming reality. In order to prevent feeding damage when fettling area. In make up a good furnace, the water glass furnace repair parts of bauxite to wipe the surface layer until the surface is dry before feeding. 4 Conclusion and production validation through practice, knot with a high-alumina lining, should be strictly controlled Al0 and Fe0 content,ugg milano, choose the right size ratio and binder content. and low temperature curing, high temperature short time baking Results fast heating process. The lining Acid Lining life is 2 to 4 times. and power saving, lower maintenance cost.
