Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Referring to the attached drawing 1, the embodiment of the invention discloses a method for manufacturing titanium-plated stainless steel by plating black titanium with water, which comprises the following steps:
step one, a water flow formed by titanizing liquid medicine is manufactured, and the cross section height of the water flow is more than 10 times of the thickness of stainless steel to be titanized. Wherein, the section height of the water flow determines whether the titanizing liquid medicine can completely and reliably cover the stainless steel to be titanized, so that the thickness of the stainless steel to be titanized is set to be more than 10 times to be ensured. In practical applications, there are many methods for forming the titanizing agent water flow, and the method recommended in this embodiment is as follows: the width-limited mode through the liquid medicine groove removes the preparation rivers, and titanizing liquid medicine flows in the liquid medicine groove promptly, under the certain prerequisite of liquid medicine groove width, only needs design import department discharge and exit discharge, can control the speed and the height of rivers in the liquid medicine groove, consequently high to titanizing process parameter control accuracy, the titanizing is effectual.
And step two, continuously penetrating the stainless steel to be titanized from one side of the water flow and from the other side at a set speed to form a contact state of relative movement of the stainless steel and the titanizing liquid medicine. Through the contact and reaction of the flowing titanizing liquid medicine and the moving stainless steel, the liquid medicine can be prevented from being layered and precipitated after being static for a long time, the solubility of the reaction liquid medicine is controllable in real time, and the stability of various index performances of the titanizing stainless steel is improved. More importantly, the titanizing liquid medicine water flow is separated from the stainless steel immediately after the first contact reaction with the stainless steel, so that the titanizing liquid medicine water flow is always in contact with the stainless steel and meets the solubility of new titanizing liquid medicine, and the condition of liquid medicine solubility reduction can not occur. In a preferred embodiment, the direction of the water flow is perpendicular to the direction of the stainless steel transmission, and in this case, the single unit of titanizing liquid medicine is in contact with the stainless steel for the shortest time, and the change of the solubility of the titanizing liquid medicine is the smallest, so that the control of the quality of the titanizing stainless steel is more beneficial.
Furthermore, the titanizing liquid medicine water flow is a circulating water flow, after the water flow is in contact reaction with the stainless steel for the first time, the solubility of the titanizing liquid medicine is compensated to reach the set solubility, and then the titanizing liquid medicine water flow is circulated until the titanizing liquid medicine is in contact reaction with the stainless steel for the second time. The liquid medicine can be recycled, the utilization rate of the liquid medicine can be improved, and the process cost is saved.
In the present method, the cross-sectional width of the water flow is inversely proportional to the delivery speed of the stainless steel. Because the reaction time required by the stainless steel and the titanizing liquid medicine is constant, when the cross section width of the water flow is wider, the distance that the stainless steel needs to move in a certain time is longer, and the transmission speed of the stainless steel needs to be faster; conversely, the narrower the cross-sectional width of the water flow, the shorter the distance the stainless steel must travel in a given time, and therefore the slower the stainless steel must travel. The practical application tests show that the production efficiency is improved by properly increasing the cross section width of the water flow and accelerating the transmission speed of the stainless steel.
And step three, finally, the stainless steel which penetrates out of the titanizing liquid medicine is the titanizing stainless steel, so that the required product is prepared.

Further, the flow direction of the titanizing liquid medicine in the liquid medicine tank 1 is perpendicular to the transmission direction of the stainless steel.
Further, be equipped with the solubility detector in the accumulator 2, still include supply tank 4, supply tank 4 is connected accumulator 2, be equipped with the compensation liquid medicine that the solubility is greater than titanizing liquid medicine solubility in the supply tank 4, but when the solubility detector detected the liquid medicine solubility in accumulator 2 and is less than titanizing liquid medicine, add the compensation liquid medicine in the supply tank 4 in accumulator 2 until the liquid medicine solubility in accumulator 2 equals the solubility of titanizing liquid medicine.
Further, the water inlet 11 comprises a plurality of water inlet holes evenly formed in the side wall of the liquid medicine tank 1, and the water outlet 12 comprises a plurality of water outlet holes evenly formed in the other side wall of the liquid medicine tank 1.
