Description
Technical field
The utility model relates in metal plate and belt hot dip process process, and metal plating liquid temperature adjustment device relates in particular to quick, the real-time setting device of a kind of metal plating liquid temperature.
Background technology
Metal hot dipping is according to the difference of metal plating liquid, can roughly be divided into galvanizing, hot dip aluminum plating, hot dip aluminum plating zinc silicon etc., no matter be that metal plating liquid, the firm degree that the thickness of its coating, luminance brightness, density, coating are combined with base material etc. have close relationship with pre-treatment, the time length of hot dip process etc. of base material material, substrate surface, but have more directly and contact with the height of metal plating liquid temperature.Metal plating liquid temperature is high, and its coating is just thick and loose, overlay coating tarnish; Metal plating liquid temperature is low, and its plating solution and base material be not just in conjunction with firm.
In producing continuously, base material is to enter into continuously metal plating liquid, and the variation of the speed that the temperature of metal plating liquid enters with temperature (slightly higher than bath temperature) and the base material of the base material entering changes.This just need to control the temperature of metal plating liquid at any time, otherwise will have a strong impact on the quality of hot dip process.
Take galvanizing as example, hold the container of zinc liquid in zinc pot, the volumetric ratio of zinc pot large (generally having zinc liquid tens to hundreds of ton), the method that now improves zinc liquid temperature is more, and it is just very difficult to reduce in time the temperature of the so much zinc liquid of whole pot.If zinc liquid temperature reduces not in time, will greatly affect the quality of product.Now large multiplex reduction base material enters the speed of zinc liquid or carries out cooling to zinc liquid surface air blast in zinc pot with blower fan.But aforesaid method all cannot reduce zinc liquid temperature in time.
Utility model content
In order to solve the adjustment that metal plating liquid temperature in above-mentioned prior art cannot be real-time, and affect the problem of subsequent thermal immersion plating quality, the invention provides a kind of metal plating liquid temperature high-speed adjustment device, it is characterized in that being fixedly installed metal straight pipe logical in metal plating liquid, described metal straight pipe adopts the setting of sealing up and down, and connect water inlet pipe at described metal straight pipe top, in described metal straight pipe upper portion side wall, place arranges connection upflow tube.
This is novel be provided with one up and down the metal straight pipe of sealing be inserted in metal plating liquid, and fixed, the top of straight tube connects water inlet pipe, and the upper portion side wall of straight tube connects upflow tube, more than described water inlet pipe and upflow tube are all positioned at metal plating liquid liquid level, excessive water is discharged from upflow tube.Take galvanizing as example, in the time that the temperature of zinc liquid is greater than 470 ℃, in water inlet pipe, pass into cold water, and zinc liquid is stirred to cooling equally, so that zinc liquid temperature is even in zinc pot; In the time that zinc liquid temperature is less than or equal to 450 ℃, stop supplying water in water inlet pipe, reach the object to metal plating liquid cooling fast with this.
Preferably, described metal straight pipe internal diameter is that 200mm-300mm is advisable.
Preferably, described water inlet pipe internal diameter is 25mm-50mm, and described upflow tube internal diameter is that 50mm-80mm is advisable.
Preferably, the length that metal straight pipe is inserted in metal plating liquid is 1.2m-1.7m, and described metal tube bottom is not less than 500mm with the distance of plating pot bottom.
According to plating pot capacity and metal-plated liquid measure in plain metal strip continuous hot-dipping, calculate by simultaneous test and rate of temperature fall, determine above-mentioned metal straight pipe internal diameter, and the optimum parameter of water inlet pipe and upflow tube internal diameter, guarantee to pass into after heat-eliminating medium in metal straight pipe, the rate of temperature fall of its metal plating liquid can meet Production requirement, and avoids the waste for heat-eliminating medium as far as possible.
The utility model is skillfully constructed, and implements convenient and swiftly, is circulated in metal straight pipe by heat-eliminating medium, and metal plating liquid is carried out to depth heat exchange from shallow to deep, and its heat exchange efficiency is high, and cooling-down effect is remarkable.
Accompanying drawing explanation
The structural representation of the metal plating liquid temperature high-speed adjustment device that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.As shown in Figure 1, the metal plating liquid temperature high-speed adjustment device that the utility model provides, take galvanizing as example, in zinc pot 5, be fixedly installed a metal straight pipe 1 sealing up and down, and be inserted in galvanizing flux 4, metal straight pipe 1 its top is provided with water inlet pipe 2, upper side is provided with upflow tube 3, in the time that needs are lowered the temperature to galvanizing flux, in water inlet pipe 2, pass into heat-eliminating medium, it can be water coolant, water coolant flow into the inside of whole metal straight pipe 1 by water inlet pipe 2, because metal straight pipe 1 has adopted the setting of sealing up and down, therefore, excessive water coolant will be discharged from upflow tube 3, and more than upflow tube 3 is all arranged on galvanizing flux liquid level with water inlet pipe 2.Constantly in metal straight pipe 1, inject water coolant, and constantly from upflow tube 3, overflow through the water coolant of heat exchange, circulate with this, to reach the object to galvanizing flux 4 fast coolings.When metal straight pipe 1 is lowered the temperature to galvanizing flux 4, can also stir zinc liquid 4 with stirrer, so that zinc liquid 4 temperature are even in zinc pot.Warm when suitable (in the time that zinc liquid temperature is less than or equal to 450 ℃) when zinc liquid 4, stop supplying water in water inlet pipe 2.Insert the material of the metal straight pipe 1 in zinc liquid 4 and can use OOCr17Ni14Mo2 (316L) stainless steel, the corrosion with anti-Zn solution 4 to pipe, the work-ing life of prolongation pipe.
The present embodiment is used to the zinc liquid cooling of the metal plate and belt hot dip process of our company.Water inlet pipe 2 internal diameters are 32mm, and upflow tube 3 internal diameters are 50mm, and metal straight pipe 1 height is 2000mm, and internal diameter is 250mm, and upflow tube 3 is 250mm apart from metal straight pipe 1 top.More than water inlet pipe 2 and upflow tube 3 are all positioned at zinc liquid liquid level, the height of upflow tube 3 and zinc liquid leave certain distance, and the one, convenient installation, the 2nd, in zinc pot, the liquid level of zinc liquid has increase and decrease in the time producing, and need reserve the space of increase and decrease.Metal straight pipe 1 bottom is 500mm apart from the distance of zinc pot 5 bottoms.
The metal plating liquid temperature high-speed adjustment device arranging by above-mentioned parameter, by calculating, final definite, if galvanizing flux is 50 ton hours, the rate of temperature fall of this device is 2.48 ℃/min, that is to say, by this metal plating liquid temperature high-speed adjustment device, the galvanizing flux of 50 tons is lowered the temperature, can make zinc liquid per minute reduce by 2.48 ℃, meet the needs of actual production completely.
Above-mentioned is only ultimate principle of the present utility model, any restriction of not the utility model being made, and every equivalent variations of it being carried out according to the utility model and modification, all within protection domain of the present utility model.
