Description
Technical field
The present invention relates to cable preparation field, particularly a kind of mineral fireproof cable rolling preparation method andRoller mill.
Background technology
Along with the increase year by year of electrical fire incidence in fire generation, therefore to electric wire fire protection requirementIncreasingly urgent, the fireproof cable of domestic production at present all adopts traditional mineral insulation copper sheath drawing process,Have following shortcoming: the length of 1, producing cable is short, larger cross-section maximum length is tens of rice only, while layingNeed have many transition joints, not only expense is high, to lay difficulty large, and it is in service greatly to have increased cablePotential faults. 2, the cable material utilization rate of drawing process is low, and loss is large, and cable cost is high, averageWaste of material is 4.2%, and product percent of pass is up to 85%. 3, the repeatedly electric furnace in cable drawing processAnnealing, power consumption is large, and average power drawn accounts for 60% of fuels and energy. In view of above situation, passThe popularization of the fireproof cable that the drawing process of system is produced and use have all been subject to certain restriction.
For this reason, having at present China Patent Publication No. is that CN101315819A discloses a kind of large size mineralThe preparation method of insulated cable, this preparation method mainly solves existing drawing molding cable production processPower consumption is large, cable length is received restriction, need the technical problem of transition joint. This preparation method comprise withLower step: carry out pickling after the alignment of package copper strips, then indulge and be bundled into circle, weld longitudinal joint by argon arc weldingForm copper conductor; In above-mentioned copper conductor, after filling magnesia powder, carry out copper conductor alignment; Copper conductor is enteredRow 4, to rolling, carries out high frequency annealing after first rolling, San road rolling He tetra-road rollings; RightCopper conductor after mill-annealed carries out putting in storage as finished product packing after surperficial inspection, rolling, detection.
Also having China Patent Publication No. is that CN101315821A discloses large size mineral insulation fireproof cablePreparation in the calendering process of copper sheath. The technical scheme of this calendering process is: large size mineral insulation is anti-The calendering process of copper sheath in the preparation of thermoelectricity cable, comprises the following steps: a. is by filling magnesia powderCopper sheath carries out first roll-in, then carries out high frequency annealing; B. after cooling bath is cooling, carry out secondRoad roll-in, then proceeds the roll-in of San road, then carries out high frequency annealing for the second time; C. through cooling bathAfter cooling, carry out the roll-in of Si road, then carry out that the laggard cooling bath of high frequency annealing is cooling for the third time.
But the preparation flow of above-mentioned two patents and equipment complexity, occupation of land space is large, and needs several timesHigh frequency annealing just can complete, and has greatly increased energy consumption, increases production cost.
Summary of the invention
One of technical problem to be solved by this invention is, for the deficiency of the problems referred to above and defect, to provideA kind of mineral fireproof cable rolling preparation method.
