The Development and Progress of Induction Furnace Ramming Materials on the Road of Science

Induction furnace ramming material is composed of silica sand, binder, boric acid, etc. The main components and mineral composition are relatively simple. It has been found through practice that if the ramming material of the quartz sand induction furnace is simply used, the service life of the furnace lining is still unsatisfactory no matter how the ratio is changed. The simple siliceous material furnace lining is not very ideal and cannot satisfy the smelting products.

In order to meet the needs of the majority of users for the production of smelted products, the majority of engineers and technicians have developed a new type of composite siliceous refractory after years of research on the basis of siliceous materials. The advent of this material has solved the problem of smelting furnace age. Low, anti-erosion, anti-corrosion melting problem.

The mineral composition of the ramming material for quartz sand induction furnace: it is made of quartz, ceramic composite binder, fused quartz, impermeable agent and other materials. It has the following characteristics after being verified by many enterprises of large tonnage and small tonnage:

1）焼結層が薄い。

2）熱効率を改善します。

3）高温での物理的および化学的変化は小さい。

4）優れた保温性能。

5）ライニングは良好な細孔密度と小さな膨張係数を持っています。

6）電気伝導率と熱伝導率が小さい。

7）表面構造は良好な強度を持ち、亀裂や剥離はありません。

8）安定したボリューム、耐侵食、

9）侵食防止;

10）長い耐用年数。
