Magnesium alloy crucible is a important part of magnesium alloy melting and holding furnace and its relation with production safety. Our products are made of high-quality composite plates, with molding in integral and reasonable welding line. Material of our selected are confirmed base on the laboratory experiment many times and the high temperature strength(σbï¼ÂÂÂÂÂÂÂ89MPa) can be to meet the request of crucible under the 800C.There is self-developed new corrosion resistant alloy layer welded upon the liquid level, it can be improve gaseous corrosion efficiently and prolong the crucible service life greatly.
