Product Description Hello everyone look at here!!! Please allow me to introduce our company and our products. Product Description It is used for melting gold, silver and copper. It is made of selected fused silica as the main raw material and processed by modern ceramic technology. It is mainly used for melting dental alloys, platinum, gold and other high temperature alloys. It can withstand high temperatures of more than 2800 degrees. The product has high purity, content of more than 99%, corrosion resistance, high strength, high thermal vibration resistance, 1100 oC water quenching reaction, and long service life.Next, let's talk about the data of the product.SpecificationsDiameterCapacity3 liang56mm150g5 liang76mm250g10 liang87mm500g15 liang97mm750g20 liang103mm1kg30 liang120mm1.5kg50 liang138mm2.5kg100 liang170mm5kg☆ The capacity of the above products is based on the capacity of gold as an example.There are many types of materials, which can be consulted according to your needs and technical indicators. We will provide you with product materials that meet your requirements.Detailed PhotosPrecautions for using fused gold bowls!A. The first use of the crucible is recommended to be placed in an oven at around 100 oC and baked for 120 minutes to remove moisture;B. Before melting gold and silver, evenly sprinkle borax on the bottom of the melting bowl to prevent sticking during the melting process;C. The use of a molten metal bowl involves using an open flame to aim at the metal inside the bowl and burning it. Gas should not be used to burn the bottom of the bowl, as most of the heat transfer is absorbed by the molten metal bowl, so it cannot reach the melting point of the metal;D. During transportation, there may be bumps in the fused gold bowl. Quartz fused gold bowls are fragile and can be used normally if their integrity reaches two-thirds. If you cannot accept bumps, please be cautious and sign for them after acceptance. Once signed, it is considered that the product is complete;E. When the heating and cooling rate of corundum products is below 1200 oC, it is recommended to be less than 5 oC/minute, and above 1200 oC, it is recommended to be less than 4 oC/minute;F. The speed of heating and cooling is adjusted according to the experimental equipment and the tested substance and properties. Due to the thermal expansion of the raw materials used to produce corundum products, excessive or uneven heating can easily lead to cracking of the corundum products. It is recommended to slow down the heating and cooling speed as much as possible when conditions permit during use, so as to evenly heat it, which will prolong the service life of the corundum products.
