Continuous basalt fiberThere are several questions that we write on paper!Please let me know if you have any information about itHow to choose the heating system for the crucible furnace?The commissioning process of the furnace?
Glass fiber drawing machine is a kind of mechanical equipment which is made by winding glass fiber at high speed.Wire drawing apparatus for making glass fibresThe drawing parts are mainly crucible, pool furnace, wire drawing machine and temperature control system.
Platinum crucible platinum rhodium alloy made by. Platinum is soft and should not be used alone. In order to increase its hardness, mechanical strength, or the rigidity of the crucible, 7%-10% rhodium is generally added, and more than 10% alloy is more brittle. The platinum alloy doped with 10% rhodium has a mechanical strength of 3 times the original.Platinum rhodium alloy with a high melting point, high temperature can well withstand the molten glass liquid. The utility model is an excellent resistance heating material, which can generate heat after the current is used to melt the glass liquid and rise to the temperature suitable for wire drawing. Platinum alloys have excellent high temperature oxidation resistance and chemical corrosion resistance.
Generation of platinum crucible and its only bushing connected electrode made of platinum rhodium alloy, and the crucible body and its relevant subsidiary components from refractories and. Liquid glass crucible by molten glass itself as an electrically heating resistor, or by a platinum alloy heater placed in the crucible for heating glass, can also use the resistance heater (with silicon carbide) by radiation heating glass in the glass, the glass liquid reaches the required temperature.
