304 201 stainless steel kitchen sink bright annealing furnace

What is the function of stainless steel sink annealing?
Reduce the cold work hardening effect of stainless steel after processing. After deep stretching at room temperature, the hardness of the 304 stainless steel sink material will become much harder, affecting the next process and further processing. High temperature annealing is required to eliminate the hardening effect.
This continuous gas shielded bright heat treatment furnace is mainly used for continuous bright annealing of stainless steel water tanks. After being processed by equipment, the surface of the product is bright and free of oxidation. The furnace has a stylish design, reasonable structure, energy saving, high thermal efficiency, stable production quality, safe and convenient use, and does not produce industrial pollution.

    detail

    Furnace Characteristic:

    ①Advanced temperature control : Intelligent thermostat, silicon-controlled rectifier and schneider electrical switches ensure temperature control precision of ±1℃; 
    ②The heating hearth (muffle) is made of imported Sweden high-temperature resistance nickel alloy (310S); 
    ③Heating elements: High-temp. resistance wire is used, with alumina tube frame; heating elements are arranged in an upper-lower removable to ease repair or replacing; replacing resistance wire has no impact on production; 
    ④Protective gas: mixture (hydrogen 75% and oxygen 25%) decomposed from liquid ammonia gets into the hearth and reaches gas protection effect; Product surface will become brightness and won’t be oxidized after heat treatment.
