Abstract
The invention relates to a non-ferrous metal solution heating bar which comprises a refractory ceramic framework, a flat metal belt, a protection pipe, a metal part, a connection part and a junction box. A thermocouple is arranged in the refractory ceramic framework in a penetrating mode, and the outer surface of the refractory ceramic framework is provided with a flat threaded slot. The flat metal belt is in a flat shape and is wound into the slot in the radial direction to form a heating body. The protection pipe covers and is attached to the refractory ceramic framework and the outer layer of the flat metal belt in a sleeved mode. The middle of the metal part is provided with a connector, one end of the metal part is connected with the junction box, and the other end of the metal part is connected with the heating body through the connection part. According to the non-ferrous metal solution heating bar, medium-heat-conducting media are indirectly heated, the organic material protection pipe is applied to a furnace structure which is directly heated, in addition, the heating process is equivalent to direct heating of the protection pipe of a heating bar, the heating bar is used for directly heating target liquid, in other words, heat conduction is directly conducted, the temperature of the heating bar does not need to be far higher than the temperature needed by the target liquid, and therefore even in the dry-burning state, the heating bar cannot be seriously damaged.
Description
Technical field
The present invention relates to non-ferrous metals casting field, particularly a kind of non-ferrous metal solution heating rod.
Background technology
The heating means of existing non-ferrous metal solution (keeping aluminium liquid heating in stove as aluminium dissolves) mainly contain three kinds of electric heating, gas heating and fuel Heating, wherein electric heating stable with the heating-up temperature in its stove, control flexibly precisely, the advantage such as low and energy-conserving and environment-protective are nuisanceless to the degree of oxidation of non-ferrous metal solution, be more and more subject to industry and pay attention to.Traditional electrical heating is that electrically heated rod is installed in heating furnace, oil is burnt indirectly and to be completed to target transferring heat or the mode that directly adds thermal target liquid, reduce cost, heating-up temperature is precisely controlled, but heat transfer efficiency and heat conversion are lower, indirectly cause the inessential oxidation of non-ferrous metal solution, also shorten the useful life of heating furnace simultaneously; Directly add and hanker heating rod and can directly contact with target liquid, heat is absolutely conduction almost, and its heat transfer efficiency and conversion ratio are the highest, and the energy is fully used, energy-conserving and environment-protective, and heating rod and furnace chamber need ceaselessly clean, and this may realize hardly.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect that how to overcome prior art, and a kind of non-ferrous metal solution heating rod is provided.
For solving the problems of the technologies described above, this non-ferrous metal solution heating rod comprises refractory ceramics skeleton, metal bandlet, protection tube, metal portion, connecting portion and terminal box, wherein said refractory ceramics skeleton inside is equipped with thermocouple, on outer surface, have the flat wire casing of screw-shaped, described metal bandlet is flat, radially be wrapped in this wire casing, form heater, described protection tube jacket is also close to refractory ceramics skeleton and metal bandlet skin, described metal portion middle part is provided with joint, this metal portion one end connects described terminal box, the other end connects described heater by connecting portion.
As optimization, described refractory ceramics skeleton be the heat-stable ceramic that is mixed with electrically conductive particles, its can infrared emittance be high and resistance is less electro-conductive glass pipe substitute.
As optimization, this non-ferrous metal solution heating rod entirety is L-shaped, and described joint is right angle bending joint.
As optimization, this non-ferrous metal solution heating rod entirety is directly bar-shaped, and described joint is horizontal bidirectional joint.
