एल्युमिना अस्तर सामग्री ओभन प्रक्रियाले इन्डक्शन फर्नेसको सेवा जीवनलाई असर गर्नेछ

The oven is the process of obtaining a sintered layer for the alumina lining material. The quality of the sintered layer directly affects the service life of the furnace, and the oven is an important link.

After the oven cavity is built, the oven should be dried immediately; before the oven, check whether the electrical equipment and cooling water system are normal; the oven must be carried out in strict accordance with the oven process. The oven process is the key factor in the oven process, the specific points:

① यो तताउने गति नियन्त्रण गर्न आवश्यक छ, विशेष गरी ओभनको प्रारम्भिक चरणमा। यदि तताउने गति धेरै छिटो छ र भट्टीको अस्तरमा नमी धेरै छिटो डिस्चार्ज हुन्छ भने, दरारहरू सजिलै बनाइन्छ, जसले भट्टीको जीवनलाई धेरै छोटो बनाउँछ।

②When the furnace lining is heated to 573°C, the quartz will expand too fast during the phase transition process, which will easily cause cracks or even peeling. Therefore, the heating speed should be slowed down when heated from 400°C to 600°C, and the temperature should be kept for 1h~2h at 870°C. , So that it can slowly and completely phase change.

③अभन। पछिल्लो चरण sintering र होल्डिंग छ। sintering तापमान विशिष्ट अपवर्तक सामग्री मा निर्भर गर्दछ। सामान्यतया, यो आशा गरिन्छ कि अस्तर मोटाई को 30% को मोटाई संग एक sintered तह प्राप्त गर्न सकिन्छ। तसर्थ, sintering तापमान सामान्यतया 50-100 ℃ ट्याप तापमान भन्दा बढी छ।
