Non-Oxidation Heat Treatment Furnace

Description

The following is non-oxidated heat treatment compared with traditional heat treatment. Producing one ton wire in traditional technics heat treatment 1) loss of oxidating: About 0.*5% equaled $1.*2 The price of wire is $**5.*1 per ton 2) loss of acid splitting: $2.*6 Amount to a: About $4.*0 Producing one ton wire in non-oxidated heat treatment 1) gas loss of ammonia resolved: About 5.*3m3, equaled $0.*2 ( one kg. Liquid ammonia may produce 2.7 m3 mixed gas of nitrogen and hydrogen, the price of one kg. Liquid ammonia is about $0.*7. ) 2) electricity: 0.*3 linear measure, $0.**8($0.**8/linear measure) Amount to about $0.*3 Conclusion: After the contrast of two terms, non-oxidated heat treatment may reduce cost $3.*6 for producing one ton wire than traditional heat treatment. The feature of non-oxidated heat treatment equipment: 1. The steel wire is not oxidated after heat treatment, steel wire reducing loss of oxidation about 0.*5%. 2. The steel wire do not require acid cleaning, reducing the cost of acid corrosion about $2.*6 per ton. 3. Do not require acid cleaning, being favorable to environment protection and improved operation condition for workers greatly. On the base of absorbed overseas advanced burning technology, domestic ripe ammonia resolved and purifying device, the technics of non-oxidated heat treatment steel and metal band is reformed and designed out. At present the technic is applied at many factories of stainless steel wire brightness heat treatment, non-oxidated heat treatment of aluminum wrapped steel wire, frontal processing of metal band hot galvanizing, frontal processing of soft steel wire electroplating, spring steel wire oil hardening or tempering.
