Degreasing apparatus for elongated materials

Abstract

A degreasing apparatus for an elongated member including a treatment room sequentially divided in an isolated fashion and along the feeding direction of the elongated member into a degreasing chamber, a predrying chamber and a finish drying chamber. At least one pair of rotary brushes are provided in the degreasing chamber. The degreasing chamber is also provided with means for jetting out a degreasing liquid in a direction toward the inlet side of a contact area between the brushes and elongated mechanism. Elastic degreasing members are provided, respectively, at the inlet and outlet sides of the degreasing chamber to remove oil or grease from the elongated member before it enters the degreasing chamber and to wipe off any degreasing liquid remaining on the elongated member prior to passing the same into the predrying chamber. The predrying chamber houses a mechanism for jetting out water or steam against the elongated member while the finish drying chamber is provided with a mechanism to blow hot air against the elongated material and to dry it completely. The above degreasing apparatus can be formed in a reduced size and convenient for coupling with drawing machine and/or roller straightening machine, thus enabling continuous treatment of elongated members. Owing to the mutual isolation of the chambers, their respective treatment media can be saved and the overall processing efficiency can be improved.
