What Are The Surface Residues Of Titanium Valve Parts? How Do We Clean It Up?

What are the surface residues of Titanium Valve Parts? How do we clean it up?

Compared with other artifacts, Titanium Valve Parts does have some unique, but it also can't avoid Titanium Valve Parts forming after cleaning, the purpose is to remove residues in the process of making all kinds of bad phenomenon, to achieve excellent quality Titanium Valve Parts.

By cleaning, the dust on the surface of Titanium Valve Parts can be removed directly, because it is often made in the dust area, so it is inevitable that the casting will have dust. Although the dust on the Titanium Valve Parts can be removed with water or alkaline solution, it should be noted that high pressure water or steam is needed to clean up the adhesion of the dust.

Cleaner can effectively remove the Titanium Valve Parts floating on the surface of iron powder or embedded iron, these free iron if it is not completely clear in time, will be led to the main culprit of corrosion of castings erosion. The float powder can be removed with the dust, and some adhesion is strong and must be treated according to the embedded iron.

In addition to the above residue need to be cleaned, Titanium Valve Parts surface scratches, rust stains also need to be cleaned. But it is useless to rely solely on the cleaning of water, and need to adopt mechanical methods, such as polishing, polishing and so on, to restore the Titanium Valve Parts to a good surface.

As a typical titanium valve part, k-type Titanium Valve Parts have many advantages, such as the above cleaning link. With magnesium and rare earth magnesium combined with the golden ball, agents to join before pouring molten iron, the graphite spheroidizing, the stress concentration is reduced, the pipe material has high strength, elongation, impact resistance, corrosion resistance, good sealing, etc.

After cleaning the surface, K type titanium surface quality of the valve parts fitting ears can also comply with relevant standards, both its intrinsic quality and external quality, greatly improve the reliability of pipeline operation.

1, the power supply

(1) the power density configuration of the Titanium Valve Parts. High configuration, quick melting, good energy saving. Whether the Titanium Valve Parts can maintain high power factor to deliver the electricity in the furnace is also the difference of energy consumption;

(2) the efficiency of the induction Titanium Valve Parts and the electrical efficiency of the induction coil. (the total efficiency of advanced induction Titanium Valve Parts is as high as 75 %, the induction coil is as high as 85%, and the domestic is 73 % and 80 % respectively);

(3) conversion efficiency of medium frequency power supply. It is 97% ~ 98% abroad, domestic nearly 97%, mainly in the efficiency of reactance and capacitance;

(4) the arrangement of the Titanium Valve Parts unit. The distance from the power source to the furnace, the length of the copper discharge and the length of the water-cooled cable, the distance from the power supply to the voltage one high voltage transformer is the influence factor.

2. Melt

(1) the cleanliness of the surface of the furnace (e.g., 5% sundry, 5% of power to melt the impurities) will also affect the life of the lining.

(2) if the length of the furnace block is suitable, it will affect the electric efficiency and the melting quality of the Titanium Valve Parts, which are generally suitable for 200 ~ 300mm blocks.

(3) there is liquid metal in the furnace. The residual liquid takes up 15% of the capacity of the furnace, and too little of it will intensify the overheating of the iron water, which will reduce the effective use of the iron water and increase the energy consumption of the unit. When the molten iron is emptied, the power factor decreases and the melting speed decreases.
