High temperature thermal container (high temperature crucible) solutions
Refractory metal tungsten, rhenium, molybdenum and their alloy materials are often used to make high-temperature heat vessels (high-temperature crucibles) above 2000°C. They have high melting point, high strength and hardness, good high-temperature performance, low resistivity, small expansion coefficient, and electronic escape. Feature such as small effort. As a container for high-temperature environments, this type of crucible is widely used in the field of sapphire crystal growth, rare earth smelting, coating and other industries. Tungsten, rhenium, molybdenum or their alloy crucibles have different production processes, such as sintering forming, welding forming, stamping forming, and spinning forming according to different dimensions and usage conditions. Among them, sintered forming products are the most widely used. For miniature and small crucibles, forged bars can be turned or stamped. The welding process adopts rolling sheet hot bending forming, and finally fixing by welding. Spinning forming is suitable for the production of thin-walled crucibles with high technological requirements. Rheniumet has many years of experience in the production of pure tungsten, rhenium, molybdenum or their alloy crucibles. It can be fully customized in terms of density, size, material grade, and service life to meet the needs of users in different working conditions.
