摘要： PURPOSE:To fix a liq. level by adjusting the amt. of the liq. to be discharged from the liq. discharge box at the lower part of a tank and surrounding a strip with a partition wall having many through-holes in the box. CONSTITUTION:A strip 1 is supported by a deflector roll, introduced into a vertical tank brought into contact with the liq., sent downward and discharged to the outside from a seal plate 3. The liq. is supplied from the upper part and discharged from the liq. discharge port 6 of a lower liq. discharge box 2. The flow rate is adjusted by the valve 10 of the discharge port 6 to fix the liq. level in the tank. A partition wall 5 is provided to surround the strip 1 in the box 2, and the partition wall 5 has many through-holes 5-1. The liq. is allowed to flow with respect to the strip 1 by the effect of the through-holes 5-1. Since the liq. level in the tank is fixed, plating and pickling are stably performed.

摘要： PURPOSE: To enhance liquid discharging efficiency and to improve liquid draining performance by forming many circumferential grooves on roll surfaces. CONSTITUTION: The surfaces of the liquid draining rolls 10 are provided with rubber linings having a thickness of 5 to 10mm, on which surfaces circumferential grooves 11 are formed. The pitch P of these circumferential grooves 11 is about 1.6mm the opening angle θ of the circumferential grooves 11 is 120 deg. and the depth of the circumferential grooves 11 is about 0.4mm. The contact state with a sheet 12 is roughened and the draining effect of the circumferential grooves 11 is lowered if the pitch P is too wide. Effective draining is not formed if the pitch is too narrow. About 0.5 to 2mm is, therefore, preferable. The depth (h) is preferably 0.1 to 1mm. The angle θ is selected from a range of 40 to 150 deg.. As a result, the slip between the rolls and the sheet is prevented and the deterioration of the sheet surface by generation of flaws, etc., is suppressed.

摘要： PROBLEM TO BE SOLVED: To improve the adhesion property of a plating metal and a metallic strip by an anodic treatment prior to a plating treatment at the time of electroplating the metal on the metallic strip subjected to the activation treatment by degreasing, washing and pickling. SOLUTION: The metallic strip S previously subjected to degreasing and washing is subjected to the activation of the surfaces by the pickling treatment and is washed again. At the time of transporting the metallic strip S by means of rolls 2a, 2, 2b and electroplating the metal on the surfaces by passing the strip in a plating cell 1, the metallic strip S is first passed through an inlet side pass section 8 and is subjected to the anodic treatment by supplying the current between the strip as an anode and an electrode 3 as a cathode, by which the surfaces of the metallic strip S are reactivated. In succession, the metallic strip S is passed through an outlet side pass section 9 and the metal is electroplated on the surfaces of the metallic strip S by supplying the current between the roll 2b as the cathode and the electrode 3 facing the roll as the anode. The plating layers having the excellent adhesion property to the metallic strip are thus obtd.

摘要： PROBLEM TO BE SOLVED: To provide a dipping type treating vessel which can make a belt-like material to pass in a treating liquid without causing deformation and always with maintenance of stable running even at the time of high speed running of the belt-like material. SOLUTION: The dipping type treating vessel 1 which makes the belt-like material A such as a steel sheet to pass by revolving around a sinkroll 3 is provided with a throat plane 5a arranged facing to respective peripheral surfaces of the sinkroll at the part where the running belt-like material A begins to come into contact with the peripheral surface of the sinkroll 3 and at the part where the belt-like material A parts from the peripheral surface thereof after revolving. The throat plane 5a is shaped so that the space between the throat plane and the sinkroll 3 at a side where the belt-like material A begins to come into contact with the peripheral surface of the sinkroll 3 is gradually reduced toward the running direction of the belt-like material A and the space between throat plane and the sinkroll at a side where the belt-like material A parts therefrom is gradually enlarged toward the running direction of the belt-like material. Thereby, pressure of flow accompanying the belt-like material at the side where the belt-like material A begins to come into contact with the peripheral surface of the sinkroll 3 is raised by flow passage throttling by the throat plane 5a and pressure of flow accompanying the belt-like material at the side where the belt-like material A parts therefrom is reduced by flow passage expansion by the throat plane 5a.

摘要： PURPOSE: To prevent the generation of arc spots by forming many circumferential grooves at a specified pitch on the surfaces of rolls for energization and forming these circumferential grooves in such a manner that the top parts of the peaks formed of the circumferential grooves exist on the circumference of the same radius. CONSTITUTION: A sheet material 13 is clamped and energized by the rolls 10, 10. The circumferential grooves 11 are formed on the surfaces of the rolls 10 and the top parts 12 of the peaks are positioned on the same radius. The liquid held and wrung between the rolls 10 and the sheet material 13 is discharged from the grooves 11. The discharge efficiency is enhanced and liquid films are hardly formed between the rolls 10 and the sheet material 13. The rolls 10 and the sheet material 13 come into stably contact with each other at the top parts 12 of the peaks of the rolls 10. The generation of the arc spots generated by the unstable contact of the rolls 10 with the sheet material 13 due to the liquid films is prevented. The slip between the rolls 10 and the sheet material 13 does not arise and the flaws on the surfaces of the sheet material 13 are not formed. The meandering of the sheet material 13 is thus prevented.
