Abstract
The utility model relates to an internal thermal nonferrous metal fusion heating furnace used for hot immersion plating, which is suitable for the hot immersion plating of nonferrous metal especially superhuge hot immersion plating engineering of the level of hundred tonnes. A furnace body is composed of a steel plate casing, a heat insulating material layer and a fireproofing material layer. A crucible is arranged in the furnace body; an immersion style heating pipe is arranged at the side of the crucible and is inserted into the crucible. A mud settler is arranged at the bottom of the crucible, and a drain hole is arranged at the end part of the mud settler. The utility model has the characteristics of long service life, high thermal efficiency, safe operation and maintenance and high quality of hot immersion plating.
Description
The utility model is a kind of internal heat type used for hot dip galvanizing non-ferrous metal melting heating furnace.Be applicable to the non-ferrous metal hot-dip, particularly hundred tonnes of oversized immersion plating engineerings.
The maintenance of dissolving and bathing temperature of non-ferrous metals such as aluminium, zinc during hot dip at present, be by means of outer hot cooking-pot type fusing immersion plating stove, outside having the following disadvantages: 1, the plating pot of this outer hot cooking-pot type immersion plating stove adopts cast iron, cast steel or is welded by steel plate, easy and the plating pot metal generation erosion of immersion plating molten metal, particularly aluminium and most of metal and nonmetal formation eutectic, fusing point is lower than 750 ℃.Use and to be bored a hole by corruption soon, thereby use the metal life-span short.2, outer hot cooking-pot type fusing immersion plating stove because take be the combustion heat by heating heating or fuel from the outside of plating pot to the mode of non-ferrous metal indirect, its thermal efficiency is very poor, in case plating pot etch leakage, high-temperature liquid metal flows out, and equipment breakdown will take place, even terrible disaster.4, external-heat plating pot is because be irony, and plating pot surface portion iron aluminide is dissolved in the molten aluminum, makes aluminium liquid polluted by iron, will influence the quality and the outward appearance of coating.
The purpose of this utility model is the weak point that exists at above-mentioned immersion plating stove, a kind of internal heat type non-ferrous metal melting immersion plating stove with internal heat type heating tube, crucible is provided, have long service life, thermal efficiency height, energy safety work, help improving the advantage of hot-dip quality.
The internal heat type non-ferrous metal melting soaks the blunderbuss stove and takes following mode to realize: immersion plating stove primary structure is by the immersion heating tube, and crucible, body of heater are formed.Crucible is contained in the body of heater, and body of heater is made of outer cover of steel plate, insulation material layer, refractory masses, and crucible is housed in the body of heater, and the immersion heating tube is installed in the crucible side, inserts in the crucible, and the sediment groove is arranged at the crucible bottom, and there is discharge port sediment groove end.The body of heater outermost layer is an outer cover of steel plate, and device has refractory material between outer cover of steel plate and the crucible, and heat-insulating material makes the crucible good heat insulating, and heat is not easy to distribute, and to reduce thermal loss, improves the thermal efficiency.Crucible adopts refractory material to make, and it is good to have a stability at elevated temperature, the characteristics that impermeability is good.The immersion heating tube is a kind of heating tube of internal heating type, and outermost layer is that anti-corrosion, heat resisting ceramic materials layer is installed in a pincers pot side, has some immersion heating tubes and is arranged in together, can be simultaneously to immersion plating metal material heating in the crucible.The immersion heating tube is plugged on good and have in the crucible that impermeable refractory material makes until the bottom by stability at elevated temperature, utilize the burning of coal gas in the hot or pipe that heating sends in the immersion heating tube, directly heating makes its fusing to non-ferrous metals such as aluminium zinc, and then keep certain bath temperature, to carry out the hot-dip operation.At crucible of the present utility model bottom lowest part, " ∪ " shape sediment groove is arranged, there is the gradient that glides and be inclined to the crucible bottom to the sediment groove, in an end of sediment groove discharge port is arranged, and the sediment groove is provided with to discharge port and flows to gradient.In the immersion plating operation, the sediment gradient of generation guiding sediment groove, and then flow out from discharge port.
The utlity model has long service life, thermal efficiency height (can bring up to 40～60%), operate, keep in repair safety, can improve the characteristics of hot-dip quality, be applicable to the hot-dip operation, particularly hundred tonnes of super-huge hot-dip engineerings.In addition, also be applicable to the non-ferrous metals casting industry.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an internal heat type non-ferrous metal melting immersion plating furnace structure schematic diagram.
Fig. 2 is an internal heat type non-ferrous metal melting immersion plating furnace structure cutaway view.
With reference to accompanying drawing, internal heat type non-ferrous metal melting immersion plating stove is made up of immersion heating tube (1), body of heater (2), crucible (6).Wherein the outermost material of heating tube (1) is that high temperature resistant, anti-molten aluminum, zinc corrosive nature are good, porosity is low, thermal conductivity factor is big, thermal coefficient of expansion is little, and has a material of high thermal shock stability, heating can be set in the pipe, adopt Electric heating, also can adopt the combustion gas mode of heating of coal gas at combustion inner pipe, heating tube is plugged in the crucible (6), up to its bottom (4).Body of heater (2) is made up of refractory material, heat-insulating material and outer cover of steel plate.Crucible (6) is good and have impermeable refractory material and make by stability at elevated temperature, is used for holding non-ferrous metal liquids (3) such as aluminium, zinc.Lowest part in crucible bottom (4) has " ∪ " shape sediment groove, and there is the gradient that glides and be inclined to the crucible bottom to the sediment groove, and deep gouge is provided with to discharge port and flows to gradient, discharges from slag-drip opening from deslagging with the guiding sediment.Crucible adopts stability at elevated temperature good and have impermeable refractory material and make.When the immersion plating operation, immersion heating tube (1) utilizes electric heating or the gas-fired heat sent in its pipe, by heat radiation conduction non-ferrous metals such as the solid aluminum that held in the crucible (6) or zinc is heated, be melted into plating bath (3) until it, thereby carry out hot-dip.The sediment that produces in the immersion plating in time deposits in " ∪ " shape groove, discharges from slag-drip opening along the slope.
The immersion heating tube is a kind of heating tube of internal heating type, and outermost layer is anti-corrosion, heat-resistant material layer.
