Steel/Stainless Steel Thermal Refining Along with more requirements of steel tube products, to ensure product quality while extend product quantity becomes key point of market competition, according to this key point, we design different thermal refining equipment to fulfill blank market inside, equipment mainly refers to fields of seamless steel tube, steel strand, stainless steel welded pipe, use in steel tube, steel bard thermal refining, stainless steel tube black solid melting, bright annealing. Product Introduction Equipment power and working frequency is most important technical specification, production capacity determine equipment power, heating effective thickness determine working frequency. According to client offered annual production capacity, we calculate by producing 320 days per year, working 20 days per day, calculate hardening heating module total power and tempering heating module total power by equipment power theory. Consider of practical use, to avoid unpredictable problems affect production efficiency, we design power to be 110% of theory power: For example, design hardening heating total power 2750kw, separate into 3 modules, one module is preheat module, rated power 1000kw, frequency 1000Hz, 2nd module is heating module, rated power 1000kw, frequency 1000Hz; 3rd module is average temperature module, rated power 750kw, frequency 2500Hz; 3 modules combination finish hardening and heating, and then finish hardening by spraying water. If design tempering heating total power 1800kw, separate into 2 modules, one is heating module, rated power is 990kw, frequency 1000Hz, another is heat preservation annealing module, rated power 900kw, frequency 1000Hz; total power of 2 modules is 4550kw, combine and finish tempering heating and heat preservation. Process of various materials, and also use in steel wire hardening, tempering and annealing treatment.
