Domestic production of crucibles have any different? Here Otsu www.jindagg.com introduce domestic crucible has the following characteristics: 1, high-density graphite crucible makes crucible has the best thermal conductivity, thermal conductivity better than other import crucible; 2, the appearance of a special graphite crucible The glaze layer and forming a dense material, greatly improving the corrosion resistance and prolong its service life; 3, graphite crucible graphite components used in all natural graphite, thermal conductivity is very good. After heating the graphite crucible can not immediately be placed on a cold metal table to avoid it because of the rapid cooling and rupture. Many kinds of a small number of the most suitable melting alloy crucibles. When you want to change the type of alloy, graphite crucible only need to exchange. When other methods such as melting furnaces and non-reflective crucible induction melting furnace, suitable for a large number of single alloy melting, melting alloys if the conversion type, if you do not replace the lining of refractory metal contamination can occur. http://www.jindagg.com/products_view.asp?id=1064
