The reaction temperature needed is high, and energy expenditure is big, requires high to refractory material；Existing electric arc heated production calcium carbide technology can not utilize
Powder, causes the waste of powder, causes the increase of production cost indirectly；Produced in existing electric arc heated production calcium carbide technology
High-temperature flue gas, the heat that the high-temperature flue gas contains can not make full use of.Therefore, how designing one kind can utilize powdery former
Expect as raw materials for production, make full use of the heat of product, reduce reaction temperature, the calcium carbide production technology of low cost, turn into current
It is badly in need of the technical barrier solved.
