Canal of stainless steel solder solders the solution of clearance

1, canal of stainless steel solder solders temperature control. Solder the effect that temperature basically suffers high frequency backset to heat up power, formula is knowable related the basis, high frequency backset heats up power to basically suffer the effect of voltaic frequency, the square of eddy current hot power and voltaic drive frequency becomes direct ratio; and voltaic drive frequency suffers the effect of incentive voltage, electric current and capacitance, inductance again. Incentive frequency formula is: F=1/[2 π (in CL)1/2] type: F- incentive frequency (the capacitance in Hz);C- incentive loop (F) , capacitance = n / the inductance in voltage;L- incentive loop, inductance = flux / the type on electric current is knowable, square root of the capacitance in incentive frequency and incentive loop, inductance becomes inverse ratio, perhaps become direct ratio with the square root of voltage, electric current, the capacitance in wanting to change loop only, inductance or voltage, electric current can change the size of incentive frequency, achieve control to solder thereby the purpose of temperature. To mild steel, solder temperature control is in 1250~1460 ℃ , can satisfy solder of tube wall thick 3~5mm to show a demand. Additional, solder temperature also can solder through adjusting speed will come true. When input quantity of heat is insufficient, temperature solders along short of by the side of the welding line that is heated, metallic organization still carries solid state, when form incomplete fusion or was not worth, the welding line brim that is heated solders more than temperature, generation is burned too or frit drips, make welding line forms fusion hole. 2, the control of extruding force. Two margins that provide semifinished product heat to solder after temperature, below the extruding of compression roller, form collective metallic grain to be permeated each other, crystallization, form firm welding line finally. If extruding force is too small, the amount that forms collective crystal is small, strength of welding line metal drops, if extruding force is too large,the meeting after getting power produces craze; , will make the metal of melt condition is squeezed to give welding line, not only reduced welding line intensity, and the burr of inside and outside with meeting many generation, cause even solder build seam wait for blemish. High frequency induction encircles positional adjusting control. Circle of high frequency induction should be close to compression roller position as far as possible. If inductive circle is apart from when compression roller is further, heat effectively time is longer, hot influence area is wider, welding line intensity drops; conversely, welding line brim heats insufficient, extruding epigenesis undesirable.
