A coater blade and backing roll combination contains a coater blade having an elastic steel blade with a wear-resistant coating formed thereon. The wear-resistant coating has a hardness greater than that of the elastic steel blade and is provided on an edge of the blade to define a coater surface for contacting with a moving surface of coated paper on the backing roll. The backing roll has a concave outer surface having a curvature corresponding to a quadratic equation and the coater surface has a concave curvature corresponding to the quadratic equation.

Coater blades and their manufacturing methods

A roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer is disposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.

Roll with composite coats

This invention relates to a production method of a mold for continuous casting comprising the steps of: providing a cooled water path in the mold water cooling mechanism; filling the cooled water path with a wax; making the wax surface uniform; providing a copper or copper alloy stratum on the wax surface by electrolytic plating; removing wax from the cooled water path and uniting the mold water cooling mechanism with the mold as one; and comprising the additional step of providing a copper or nickel plating on the surface on which is provided the cooled water path in the mold water cooling mechanism before depositing wax in the path.

Production method of a mold for continuous casting

A method of reproducing a composition of an electrolytic polishing solution for a niobium material, characterized in that, when the composition of the electrolytic polishing solution for the niobium material which is composed of HF, H.sub.2 SO.sub.4 and water is lowered in the concentration of HF, the composition is replenished with fluorosulfuric acid and water in an amount equimolar therewith or so in order to recover the concentration of HF while the content of water is maintained substantially at a constant level.
