摘要： A titanium slab is appropriate for hot rolling, is produced by electron beam melting furnace, has superior linearity so that it can be fed into a hot rolling machine without performing breaking down process or other subsequent correcting process after production, and has good structure having no cracks at the corner parts. A process for production thereof is also provided. The titanium slab is directly produced by a mold of an electron beam melting furnace, and has the deformation of not more than 5 mm for the thickness direction versus the longitudinal direction and deformation of not more than 2.5 mm for the width direction versus the longitudinal direction, both per a length of 1000 mm of the slab. The process for production of this titanium slab for hot rolling has a step of using an electron beam melting furnace in which its rectangular mold has mold walls of a long side and mold walls of a short side, and a step of pouring molten metal from one of the mold walls of a short side. Furthermore, a mold having chamfered parts at the corner parts can be used in the process.

摘要： The present invention provides a titanium material for hot rolling that enables reduction of defects occurring on the surface (in the case of a flat material or strip coil, including not only the flat surfaces but also the side surfaces and edges) owing to the hot rolling, and a method of producing the same, particularly to a titanium material for hot rolling enabling omission of an ingot breakdown process, and a method of producing the same, characterized in that it is a titanium material for hot rolling having dimples imparted by cold plastic deformation whose mean value of the heights (Wc) of the undulation profile elements is 0.2 to 1.5 mm and mean value of the lengths (WSm) thereof is 3 to 15 mm, and makes it possible to minimize surface defects occurring in hot rolling even if a process for breaking down the ingot is omitted. The dimples are formed by plastically deforming the surface of the titanium under cold condition using a steel tool having a tip shape of a radius of curvature of 3 to 30 mm or a steel sphere of a radius of 3 to 30 mm.

摘要： High quality titanium ingot is produced by using recovered titanium scrap as a raw material and adding additives. Scrap, each having individual information of identification and process profile information, is passed through automatic reading means to obtain the information and to store it in a data server. A calculating means calculates a combination of the scrap, titanium sponge and additives and feed rate of each of them so as to satisfy chemical composition and producing rate of a target ingot product using the individual identification pieces of information stored in the data server, during a beginning step of the ingot production, and transmits electrical signals corresponding to calculated results of the combination and the feed rates from the calculating means to a feed rate controlling means of each feed means of the titanium scrap, titanium sponge, and additives and then starting supply of them, and detecting means equipped at an extracting part of the ingot product reads actual producing rate of the ingot product, after the beginning step of the ingot production. The calculating means controls feed rate of the titanium scrap, titanium sponge, and/or additives based on the actual producing rate.

The titanium slab concerned is produced using an electron beam melting furnace by casting at an extraction rate of 1.0 cm/min or greater.

The apparatus for production of the metallic slabs by the electron beam melting has a metal melting part and a metal extraction part mutually separated by an air tight valve; a metal melting part has a melting chamber, electron gun, hearth, a mold of variable wall distance, and an air tight valve; and the metal extraction part has a slab chamber, an extraction base, an extracting shaft, and an drive unit for extracting the metal slab. The method for production of the metallic slab using this apparatus has a step of pulling a previous metallic slab produced in the rectangular mold out of the rectangular mold, a step of moving the short mold wall(s) of the rectangular mold to change the width of the rectangular mold, and a step of producing a subsequent metallic slab.
