Abstract
The utility model discloses a copper wire softening furnace and relates to a heating furnace for softening copper wire in the electrical wire and cable field. The utility model comprises a heat-resistance stainless steel heating tube. A magnesium oxide layer and an inner tube are arranged in sequence from the outside to the inside in the heat-resistance stainless steel heating tube; and the heat-resistance stainless steel heating tube, the magnesium oxide layer and the inner tube are in heat-conducting connection. The utility model adopts a controlling transformer with low voltage and large electrical volume to heat the heat-resistance stainless steel tube in the outer layer. In order to avoid the conduction of electricity between cable wire and the stainless steel tube in the outer layer caused by directly heating the stainless steel tube in the outer layer, a magnesium oxide tube is further arranged in the outer layer, and a seamless heat-resistance stainless steel tube is sleeved in the magnesium oxide tube. The stainless steel tube in the outer layer, the magnesium oxide layer, and the seamless heat-resistance stainless steel tube are in heat-conducting connection, and heat is transmitted to the middle magnesium oxide layer from the stainless steel tube in the outer layer, and then transmitted to the seamless heat-resistance stainless steel tube to heat the cable wire arranged therein. Compared with the prior art ,the utility model has high heating efficiency, can further save 20 percent energy, and has excellent insulating performance.
Description
Technical field
The utility model relates to the process furnace of softening copper cash in the electric wire field, relates in particular to the improvement of heating tube in the process furnace.
Background technology
At present, the softening furnace of wires and cables industry adopts semi-open shape electric heating tube directly the cable that is traveling in wherein to be heated mostly.Its calorific loss is bigger, and thermo-efficiency approximately has only 65%.
The utility model content
The utility model provides a kind of closed ring that can improve heating efficiency at above deficiency, and the copper cash softening furnace of good insulating.
The technical solution of the utility model is: comprise a heat-resistance stainless steel heating tube, also be provided with magnesium oxide layer and interior pipe from outside to inside successively in the heat-resistance stainless steel heating tube, heat conduction connects between heat-resistance stainless steel heating tube, magnesium oxide layer and the interior pipe.
Pipe is the heat-resistance seamless stainless steel tube in described.
The utility model utilizes the transformer of low voltage, big electric current, to outer field heat-resistance stainless steel pipe heating.Conduct electricity in order to prevent that thereby the outer stainless steel tube of direct heating from making between cable and the outer stainless steel tube, one deck magnesia tube is set in outer tube again, a sheathed seamless heat-resistance stainless steel pipe in magnesia tube, three's heat conduction connects, heat is led intermediate oxidation magnesium layer by outer field stainless steel tube transmission, transmit the seamless heat-resistance stainless steel pipe of leading internal layer again, the cable that wears, is traveling in is wherein heated.The utility model thermo-efficiency height, existing can energy-conservation again 20% for prior art; Good insulating.
