Main parameter
2. Main structure and specifications 2.1 Furnace type Aim at heating feature of circular angle zinc bath, use side heating type, natural gas fired high speed nozzles are placed diagonal positions of the zinc bath, the outlet speed of high speed combustion products can reach 120~160m/s . Continuously heating the outside of zinc bath, through furnace inner space and original smoke mixed, the uniform heat conduction can uniformly deliver the heat to every part of zinc bath. Or that means, the circulating heat current absorb the partial heat from nozzles, and radial go around zinc bath outside, from top to down, from front to back, so can achieve uniform and high efficient heating effect, largely improve the lifetime of zinc bath. Steel structure of furnace body is welded by structural steel and steel plate. 2.2 Furnace lining structure Main lining structure of side heating area is combined heating insulation material with high temperature resistant ceramic fiber blanket and low temperature heat insulation plate. According to different part of zinc bath, use different combined material with economic consideration. Above zinc liquid, there is movable heat insulation cover, to make sure the minimum heat loss. 2.3 Heating supply Consider the thermotechnical features of the furnace, use the gas high speed nozzle to supply the heat. The nozzle is with small size, stable burning, big adjustable range, high burning efficiency, safe operation without tempering, low environmental pollution, and easy operation. Easily equip with high-tension ignition and flame monitor, to achieve automatic ignition and control. The nozzle together with mating air-gas ratio valve, use the pressure of combustion air as signal, to automatically control gas pressure, make the same pressure of gas and combustion air, accordingly keep the fixed ratio of both flows, to achieve stable air coefficient, stable burning and constant atmosphere. The system through pulse-combustion control is with easy structure, reliable running, easy operation and high precision, largely save the gas. 2.4 Smoke discharge system The smoke is discharged through the zinc bath bottom, then through air heat exchanger and furnace pressure adjusting valve into drying device. The smoke is used for drying steel wire. The waste air from dryer is collected by the fume discharge cover, then discharge through the metal fume pipe.The discharge meets the standard. 3 Portal frame The vertical portal frame is made of heavy steel structure, steel beam and steel column, enough strength and anti-vibration performance can reduce steel vibration. Around skidproof platform edge there is safety rail, to make sure the safety. 3.1 Roll shaft The roll shaft surface do the hardening treatment, with U channel, the elevation can be adjusted. On first water cooling there are two rollers, to adjust the wire, reduce the wire vibration, improve steel wire galvanized surface quality. Before entering liquid zinc, there is support-roller, through changing the position of support-roller, can adjust wire dipped length, to achieve reasonable zinc coat. 3.2 Sinker device Use SIC material, wear-resisting, anti-high temperature, anti-zinc corrosion, under normal running, the lifetime is long. Fan-shaped sinker surface is with single groove to keep wire fixed and stable wire pitch, Fan-shaped sinker surface is with zinc liquid lubricating groove, to reduce the wearing resistance between steel wire and sinker, meanwhile make sure wire not get scratched. Welding the structural steel and thick steel plate could supply enough strength for sinker supporting and lifting, and reduce the vibration to least. Immersed sinker can leave liquid zinc through turning hand wheel to run speed reducer gear box. Outlet shaft of gear box is connected directly with sinker supporter and damp device. Speed reducer gear box is installed on bottom at bath working side. Equipped with locking part can eliminate vibration and prevent sinker place abnormal changing. |
