Technical field
The present invention relates to electrothermal tube and cable processing technique field, refer in particular to a kind of production technology of stainless steel mineral matter heating cable.
Background technology
Stainless steel mineral matter heating cable, taking electric power as the energy, utilizes resistance wire to carry out heating power, and the variation of the working temperature of cable surface adopts thermostat setting, reaches best result of use.
Stainless steel heating cable, resistance silk is contained in the center of seamless stainless-steel pipe, insulate by height, high heat radiation, resistant to elevated temperatures mineral material reaches heating in vacuum, magnetic field radiation after cable energising is shielded completely, to human body and object, without any infringement, its thermal conversion rate is high, and the coefficient of expansion is little, mechanical properties strength is high, has good anti-riot performance.
The processing technology of current stainless steel mineral matter heating cable is:---" rolling again---" annealing---" drawing after steel pipe--" adds powder inlet pipe---" and adds resistance wire to fit together---" annealing is until reach finished product caliber and the requirement of rice power, the method is because the restriction of steel pipe length, adopt and manually put tube cell, cannot carry out continuous production operation, process-cycle is long, production efficiency is low, and cost is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the production technology of the mineral matter heating cable that a kind of speed of production is fast, efficiency is high, cost is low employing stainless steel band is raw material is provided.
For achieving the above object, technical scheme provided by the present invention is: the production technology of stainless steel mineral matter heating cable, described technique includes following steps: put band-cleaning-oven dry-pipe crimping-filler and resistance silk-argonaut welding-vibrations-rolling-high-frequency heating-cooling-rolling-high-frequency heating-cooling-rolling (Repeat-heating, cooling, rolling make heating cable reach dimensional requirement)-take-up-cable laying-blanking-peeling-cold and hot line connection-joint welding-joint rolling-finished product detection.
Described stainless steel band enters rolling machine by putting band machine, rinse bath, dryer, resistance wire and mineral matter are injected simultaneously, after moulding, weld, shake through over packing, enter roll mill, pass through again high-frequency heating and cooling system, after circulation rolling and annealing, reach finished size and rice power requirement.
