厚板・形鋼兼用自動ショット塗装設備の開発

Development of Automatic Shot Blast and Spray Painting Line for both Plates and Shapes at Mizushima Works of Kawasaki Steel Corp.

瀬戸 恒雄(Tsuneo Seto) 柴田 克已(Katsumi Shibata) 大部 素宏(Motohiro Obu) 中西 輝行(Teruyuki Nakanishi) 要旨 : 1978 年 7 月より稼動している形鋼の自動ショット・塗装設備は,鋼板用として使用してい たものを形鋼兼用設備に改造したものである。従来H 形状の自動ショット・塗装に対して は除錆の不確実なことと塗膜厚みむらが問題とされていたが,プローオフ装置を用いた除 錆方法,ショット粒除去方法の確立および,塗膜厚みのばらつきが少なくなり塗料原単位 の低い 3 頭ガン方式の開発による優れた自動塗装技術の確立により解決し,形鋼の鋼板の 兼用設備として国内で初めて実用化に成功したものである。 Synopsis :

An automatic shot blast and spray painting equipment, the first of its kinds in Japan as available for both plates and H-shapes, has been successfully operating since July, 1978 when it was remodeled from the one solely for plates. Difficult problems involving descaling, uniform painting, and others were solved by the following method; decaling by the use of blowing-off mechanism, development of cleaning method of blasted shot and development of tripple gun system for uniform paint film thickness and lower paint consumption.

The importance of our present work is, in order to construct many new traveling wave solutions including solitons, periodic, and rational solutions, a 2 1-dimensional Modi-

A variety of powerful methods, such as the inverse scattering method [1, 13], bilinear transforma- tion [7], tanh-sech method [10, 11], extended tanh method [5, 10], homogeneous

In this paper, we apply the modified variational iteration method MVIM, which is obtained by the elegant coupling of variational iteration method and the Adomian’s polynomials

Based on these results, we first prove superconvergence at the collocation points for an in- tegral equation based on a single layer formulation that solves the exterior Neumann

We show that for a uniform co-Lipschitz mapping of the plane, the cardinality of the preimage of a point may be estimated in terms of the characteristic constants of the mapping,

Furthermore, we also consider the viscosity shrinking projection method for finding a common element of the set of solutions of the generalized equilibrium problem and the set of

To derive a weak formulation of (1.1)–(1.8), we first assume that the functions v, p, θ and c are a classical solution of our problem. 33]) and substitute the Neumann boundary

The Dubrovin–Novikov procedure is well justified in the averaging of the Gardner–Zakharov–Faddeev bracket on the m-phase solutions of KdV for any m and provides a local
