跟著社會發展和人們糊口水平的進步,鋁和鋁合金的用量呈顯著的增加趨勢。感應爐作為鋁和鋁合金的主要熔煉設備品種,越來越受到人們的正視,因而,感應熔鋁爐用耐火材料已成為鑄做功課者非常關心的技術題目之一。 在此,就本所多年來在這方面所作的研究工作作如下敘述: 2、感應熔鋁爐用耐火材料應具備的特點 2.1工頻有芯感應爐的工作特點 2.2無心感應爐的工作特點 2.3耐火材料應知足的要求 爐襯耐火材料,不論是用于有心感應爐,仍是無心感應爐,都應知足以下要求。 ?。?/span>1)有良好的化學不亂性 ?。?/span>2)有良好的抗沖洗性 ?。?/span>3)有較高的致密度和體積不亂性 ?。?/span>4)不易產生爐瘤 ?。?/span>5)不易被金屬液潤濕和滲透滲出 ?。?/span>6)耐急冷急熱機能好
With the development of society and the improvement of people's living standards, the consumption of aluminum and aluminum alloys has increased significantly. As the main melting equipment of aluminum and aluminum alloys, induction furnaces are increasingly being faced by people. Therefore, refractory materials for induction aluminum melting furnaces have become one of the technical topics that are of great concern to casters. Here, the research work done in this area by the Institute for many years is described as follows: 2. Characteristics of refractory materials for induction aluminum melting furnace 2.1. Working characteristics of power frequency cored induction furnace 2.2 Centerless induction furnace The working characteristics of 2.3 refractory materials should meet the requirements of the furnace lining refractory materials, whether it is used for the center induction furnace, or the centerless induction furnace, should be sufficient to meet the requirements. (1) Good chemical instability (2) Good flush resistance (3) High density and volume instability (4) Not easy to generate furnace knobs (5) Not easy to be wetted by metal liquid and Seepage and exudation (6) Good resistance to rapid cooling and rapid heating
