How to smelt Nickel copper using castable refractory?

Nickel copperis copper base alloy with added nickel, shows slivery white,has metallic lustre, so is named nickel copper.It may be smelted inner electric induction furnace with power frequency with iron core and furnace liner is constructed high alumina or magnesium refractory materials .In smelting processing,The furnace liner is used quartz sand of mainly materials with sio2 who will be corroded ,because NiO2 and Cu2O belonging basic anhydride produced by oxidationboth can react with SiO2 ,and then furnace liner will be corroded. The nickel content is higher, the more serious corrosion to the lining of the melt. In the process of smelting nickel in copper nickel alloy,they easy to absorb hydrogen, content of hydrogen in the melt increases with the increase of nickel content.On ordinary copper smelting in graphite crucible,even temperature get outside 1400℃,the carbon contents of metal will rapidly go up to 0.03-0.05%,and more and more. Using charcoal as covering agent processes nickel copper smelting, It takes more than 20 minutes in metals contact with charcoal
,leading to carbon content will be more than standard limits.Refractory mortar
AMD series special Ramming mass manufactured by enterprise is better processing and formula, on the premise of ensuring product quality and service life who reduce content of quartz sand that reduce or avoid to corroded furnace liner in productive process,at the same time solve the problem with high melting point and difficult to melt metal nickel,longing using life of furnace lining.Refractory mortar

Taurus Refractory ramming mass Factory mainly engaged in professional manufacturer of development, production and sales of the refractory mixture such as melting copper, aluminum and zinc furnace lining. And supply castable refractory for copper smelting, ramming mass for molten copper,fire clay,refractory mortar, refractory cement ,refractory mixture, refractory concrete and silica sand for copper smelting.
