Title: Production of temperated glass
Inventor: TOKI MOTOYUKI
IPC: C03B19/12
Filed: 1986-04-15
Abstract: PURPOSE:To make it possible to temper silicate glass or quartz glass chemically without adding sodium to a glass composition, by immersing a plate of wet gel in a metallic compound-containing solution, diffusing the solution into the surface of the wet gel, drying and calcining the plate. CONSTITUTION:A plate of wet gel obtained by sol-gel method using a metallic alkoxide and silica fine powder as raw materials is immersed in a solution containing a metallic compound. Then, the wet gel is dried into dry gel and sintered to give tempered glass. By the procedure mentioned above, the metallic compound is diffused into the surface of the wet gel and density at the diffused part is made higher than that at undiffused part.

CONSTITUTION:For example, a slab of a silicon steel containing 2.4-4.5% Si is introduced into a heating furnace with inert-gas atmosphere of nitrogen, etc., and soaked and held, and the slab is immediately hot-roughed into a sheet bar of 30mm thickness. The surface scales are removed from the hot rolled sheet bar by means of descaling spray, and successively a hot rolled steel plate of 2mm thickness is produced by means of a finish tandem mill 1-7 of seven stands. At this time, the regulation of hot finishing temp. is done in the former stage 1-4 preceding the tandem mill 1-7 by gradually decreasing water spraying. Subsequently, the plate is pickled and finished to the final sheet thickness of 0.23mm by exerting cold rolling once or twice while performing process annealing between the cold rolling stages. After decarburizing annealing is applied to the resulting sheet, a separation agent at annealing composed essentially of MgO is applied and then finish annealing for the purpose of secondary recrystallization and purification is done.
