Before using the crucible for the first time, place it in an oven at about 105 ° C for 120 minutes.Remove moisture. 2.Do not use gasoline spray gun, acetylene gun, alcohol torch to directly heat, avoid crucibleExplosion due to uneven heating. 3. The distance between the crucible and the heating body (such as carbon tube, silicon molybdenum rod, heating wire, etc.) should be greater than2cm. 4. The bottom of the large crucible should not be in direct contact with the bottom of the furnace. It is recommended to use corundum tablets, etc.The temperature-resistant material lifts the crucible to form air convection and prolongs the life of the crucible. 5. Do not heat or cool too fast. Below 1200 ° C should be <5 ° C / minute,Above 1200 ° C should be <4 ° C / min. It is recommended to reduce the temperature by turning on the power.High temperature directly shuts off the power supply, and the early cooling speed may cause cracking.     Over the past 20 years, we have gained the trust and support of many customers.
