Ways to enhance the life of the induction furnace

Ways to enhance the life of induction furnaces The principle of improving the life of induction furnaces is that for every foundry worker, the company will have serious implications. The 坩埚 medium frequency induction furnace is a refractory fabric, the process of the medium frequency induction furnace shop, the construction process, the use of ovens and skills and other skills, the following are introduced separately. First of all, the refractory fabric refractory fabric, its performance of the medium frequency induction furnace to play the basic effect of the quality of the day.

1) There is a brick building with good fire resistance. The demand for refractory materials has a very high degree of refractoriness, resistance to high temperature heat load, no softening, no melting; high dimensional stability, high temperature and low temperature heat load resistance, not only a consistent volume reduction and expansion; Very high temperature strength and high temperature heat strength. Under high load, the refractoriness is high in the high temperature, the heat load is together, there is no strength, the creep and the collapse will not suffer from the loss; the outstanding thermal shock resistance, the temperature resistance changes drastically. No cracking, no peeling; excellent slag resistance.

2) Refractory elements. The impurities of the refractory material can form a low melting point compound at a high temperature, thereby reducing the refractory material of the refractory degree. Following the refractory material, the degree of refractoriness is low, and the amount of impurities increases as the days are reduced. Therefore, the fabric quartz sand to ensure strict control of impurities, the composition of the sand lining below the workshop: ω (SiO2) is ≥ 98.0%; ω (alumina) ≤ 0.5%; ω (iron oxide) ≤ 0.5%; ω (titanium dioxide) ≤ 0.05%, ω (water) ≤ 0.5%.

3) The ratio of the size of the refractory particles. A reasonable planning of refractory materials, this process can easily be a disadvantage in the process of building a medium-frequency induction furnace high-density refractory layer is not easy. The refractory coarse, medium and fine particles will reduce the proportion of refractory materials used by professional workshop manufacturers. The thickness ratio is as follows: 3.35 mm? 5 mm, 0.85 mm? The point is 7 〇 mm, 0.1 mm to 0.85 mm, and the tax rate below 0.1 mm is 17%, 33%, 20%, 30%.

Second, the shop medium frequency induction furnace process The life expectancy and safety quality of the shop heater of the medium frequency induction furnace have important meaning. The IF induction furnace shop checks for damage, coils, if any, the insulating varnish is applied to the damaged part, repaired; then the glass wall is mixed with water and the medium frequency induction furnace refractory repairs and tidies the wall and bottom of the intermediate frequency induction furnace, Followed by the previous laying - mica board cut fine, alarm stainless steel wire mesh, asbestos cloth, through the outer stainless steel mesh with the intermediate frequency induction furnace coil through the copper wire connection alarm, and then in the third ring of asbestos medium frequency induction furnace medium frequency induction Laying under the furnace wall, top tension; flattening the intermediate frequency induction furnace should cover up to avoid debris falling to them.
