Title: Steel for age hardening type high strength and high thermal expansibility bolt
Inventor: SATO KOJI
IPC: C22C38/12
Filed: 1992-05-14
Abstract: PURPOSE:To inexpesively manufacture a high strength bolt having high thermal expansibility by incorporating specified amounts of C, Si, Mn, Ni and V. CONSTITUTION:The compsn. of the objective steel 15 formed of, by weight, >0.65 to 1.15% C, <=1% Si, 4 to 20% Mn, 8 to 25S Ni and >0.5 to 3% V and satisfying Ni+0.5XMn+30XC--5.3X>=21, and the balance substantial Fe. C is an element for forming austenite, furthermore forms vanadium carbide with V and brings about an age hardening effect. For this purpose, its addition by is needed >0.65% at the lowest. In the case its content exceeds 1.15%, its ductility is reduced, and the header workability of a bolt is deteriorated. Mn stabilizes the austenitic phase and imparts high thermal expansibility thereto. At the time of subjecting the bolt to cold header working, it is excellent in formability because of its low proof stress and high ductility, and by the subsequent aging treatment, sufficient high proof stress can be obtd.

IPC: B21B1/16
Filed: 1981-08-05
Abstract: PURPOSE:To reduce the original unit of rolls advantageously by considerable decrease in the use of costly caliber rolls by using flat roll passes frequently in reducing of blooms or billets to bar steel, and rolling the bar steel with the caliber roll passes disposed partly. CONSTITUTION:A blank material 8 having a square section is rolled continuously >=2 times with flat rolls 9, 9', 9''. The rolled material 8 is subjected to a process for trimming the sectional shape of the material 8 by a single pass of box type rolls 10 or combined passes of diamond caliber rolls 11 and square caliber rolls 12 repeatedly each time when needed, whereby the section thereof is reduced. In this way, the twists and overturns produced when the material is subjected to continuous passes of 2 times or over with flat rolls are corrected with  the caliber roll passes, so that the continuation of the succeeding rolling is made easy. The life of the caliber rolls is remarkably prolonged by the said method and the rolling efficiency for the bar steel is improved considerably.

Subsequently, the output of the A/D converter 6 and the digital value (f) are added by an adder 7, and a new digital value (l) is calculated. Also, by an external clock (m), a new digital value (f) is updated. Said operation is repeated and an error sin(theta-phi) is added to the digital value (f) until theta=phi, and a synchro signal can be converted to a digital value. In such a way, the device can be allowed to follow up the synchro signal for rotating at a high speed.
