The invention provides a precise forging-continuous rolling production technology of a large and heavy single molybdenum rod. The production technology comprises the following steps of: 1, carrying out billet forging on the molybdenum rod by a precision forging machine to obtain a precision forging bar; 2, heating the precision forging bar; 3, rolling for the first time by a Y-shaped three-roller continuous mill to obtain a rolled molybdenum rod; 4, heating the rolled molybdenum rod; and 5, rolling for the second time by the Y-shaped three-roller continuous mill and obtaining the large and heavy single molybdenum rod of which the piece weight is 45-50kg. Deep processing of a molybdenum bar is successfully achieved by setting and optimizing each parameter in precision forging, thermal treatment and continuous rolling processes; the large and heavy single molybdenum rod, which is suitable for subsequent wire drawing, and of which the piece weight is 45-50kg, is finally produced; and the production efficiency is obviously improved. The piece weight of the molybdenum rod produced by the production technology is much greater than that of the molybdenum rod produced by a traditional technology; and the precise forging-continuous rolling production technology has no welding spot on the whole, and is even in internal organization, high in product quality and suitable for large-scale industrial production.

The invention belongs to a ceramic under-glaze decoration process, and in particular relates to a ceramic silver plating process. The process comprises the following steps of: after firing a blank, rendering with white glaze; spraying solution A; and firing the blank at the temperature of between 1,100 and 1,500 DEG C; coating a silver foil on a fired product and producing a texture effect; and spraying silver glaze and performing tempering treatment, namely finishing a ceramic silver plating process. The solution A is obtained by the method of: fully mixing 100 weight parts of silver powder,90 to 120 weight parts of 783-isophorone, 0 to 1 volume part of sodium hydroxide aqueous solution with the mass concentration of 20 to 50 percent for 5 to 10 minutes. The ceramic silver plating process of the invention gets rid of the current situation of random construction, so that the quality is easier to control and the effect difference among batches of products is reduced; in addition, the ceramics obtained by the process changes the effect of a single color in the past and has very high craft appreciation.
