Great crucible Tianjin plant to produce nearly 40 years crucible of history, I plant the production of graphite crucible, carbonized Silicon crucible furnace crucible, export-oriented crucible, shaped crucible are exported abroad, and by the majority of friends of all ages. Preferential prices, excellent quality, good service, so our products are far more Tongji. Hoping to add a heat of your business booming, welcome friends to inquire, Tel: 15200015105 QQ: 1026542668 If crucible packed with special requirements friends please contact us for further discussion. Graphite crucible has good thermal conductivity and temperature resistance, high-temperature use, thermal expansion coefficient, for emergency heat, quench with certain anti-strain properties. Acid, alkaline solution of anti-corrosive, with excellent chemical stability. Graphite crucible, due to a more than excellent performance, so in the metallurgy, casting, machinery, chemicals and other industrial sectors, is widely used in smelting alloy tool steel smelting and nonferrous metals and alloys. And has a good technical and economic results. Domestic graphite crucible production has reached or even exceeded imports crucible, especially the Yangtze River Delta region's largest graphite crucible manufacturer, Tianjin large crucible factory production graphite crucible, as the domestic crucible representative has the following characteristics: 1, graphite crucible high density makes crucibles with a best thermal conductivity, thermal conductivity better than other import crucible; 2, a graphite crucible appearance of a special glaze layer and forming a dense material, greatly improving the corrosion resistance and prolong its service life; 3 graphite crucible graphite components of natural graphite used in all, a very good thermal conductivity. After heating the graphite crucible can not immediately placed on a cold metal table, in order to prevent it from being broken due to the rapid cooling. Many types of small number of the most suitable alloy melting crucibles. To change the type of the alloy when only need to exchange the graphite crucible. When other methods such as melting furnaces and non-reflective crucible induction melting furnace, suitable for a large single alloy melt, and if converted melting alloy types, if not replace the refractory lining, metal contamination can occur.
