With high melting point, high thermal conductivity, and high strength at high temperature and other characteristics, in particular, its good heat resistance, tungsten products becomes the critical part of quart furnace. Tungsten tube, tungsten material bench, tungsten core rod, and tungsten shaper are the four parts which are most critical to quartz smelting furnace.
Quartz has a melting point of 1750 degree celsius. In order to melt quartz, it requires containers with higher melting points. Tungsten products then become the best choice. Through our many years of joint research and development with our customers, we've tailored an optimum tool for the whole quartz industry to manufacture high quality quartz.
Areas of Application
The quartz production process uses continuous melting method, that is, it needs continuous melting of quartz without stopping. Thus each stop will add high cost to the enterprise. Repeated studies prove that the properties of tungsten materials can meet the demand for quartz continuous melting process; therefore the materials are widely applied to quartz melting furnaces.
Note: For all specifications, we are able to adopt machining method to meet customers' high precision requirements.
Our company has diversified product lines for production and processing. We provide top products to our customers while carefully monitoring each production process, which ensures that we are able to provide the best quality products.
With the launch of our new technical equipment, we have successfully achieved densification process of materials in the field, Thus it meets the higher quality requirements for you. thus meeting the higher quality requirements for you. Density of tungsten material bench and core rod and other products can be up to 18. 6g/cm3 or above.
From the first tungsten tube with diameter of 200mm to 640mm today, each of our technical ability improvement can bring the quartz melting industry atechnological change.
We can produce the world's largest tungsten tube for quartz melting furnace, the inner diameter of which is up to 640mm.
We are very familiar with our customer's requirements regarding product quality; therefore we produce and deliver products with high purity and long service life.
Our technical and equipment capabilities can make sure every success of each of your technical reform.
