Title: Castable composition
Inventor: SASAGAWA YUKIO
IPC: C04B111/28
Filed: 1991-04-24
Abstract: PURPOSE:To provide a monolithic castable composition by using a refractory aggregate consisting essentially of spinel to be used as a casting material for lining a steelmaking ladle or for a vacuum degassing furnace. CONSTITUTION:A refractory aggregate consisting essentially of spinel, alkali metal carbonates and alumina cement are mixed to constitute the castable composition, the working life of the composition when cast, i.e., the important characteristic of the monolithic castable, is necessarily and sufficiently increased, and the flowability is also improved without remarkably retarding its hardening. Consequently, the applicability is drastically improved without deteriorating the resistance to spalling and slag and durability of the castable using the refractory aggregate, and the hardening due to a shortage of the working life caused in a mixer or hopper is prevented.

Filed: 1991-05-24
Abstract: PURPOSE:To raise the usability of equipment by setting the ratio of air to fuel at the time of burner ignition in response to the temperature of the water supplied to a heat exchanger and igniting in a small number of ignition by reigniting with a different ratio of air to fuel when the ignition fails and using for the next ignition the new ratio of air to fuel by which the ignition is successful.

A drive circuit 12 controls a proportional valve 5 and a blower 6 according to the detection signal for the temperature of the supplied water. When the flame of the burner 4 is detected by a flame sensor 8 and the failure of ignition is detected by an ignition judging circuit 11, the memory circuit 10 instructs a next different ratio of air to fuel to improve the ignition performance. And the memory circuit 10 renews the ratio of air to fuel by the ratio of air to fuel in which the ignition succeeds. With this arrangement it is possible to adapt for conditions of installation that are different from the conditions of setting memory data.

IPC: B21B1/46
Filed: 1989-05-15
Abstract: PURPOSE:To cool the base of a base material in a high-temp. state in the same manner as for the other three surfaces and to prevent the transverse crack at the time of hot rolling by providing a receiving stand which receives the base material in plural longitudinal positions in a heat treating chamber and disposing the injection ports of a cooling liquid injecting pipe on the rear surface of the receiving stand so as to face the base of the base material. CONSTITUTION:The base material A in a high-temp. state which is immersed in a flowing cooling liquid is received in a linear contact state by the receiving stand 18 in the plural positions nearly orthogonal with the longitudinal direction thereof. The cooling liquid is injected from the injection ports 23 of the cooling liquid injecting pipe 22 to the base of the base material A to remove the steam sticking to the base. The disturbance of a rapid cooling effect by the steam sticking to the base F of the base material A is, therefore, obviated and the contact of the base F of the base material A and the receiving surface 20 of the receiving stand 18 is a linear contact to minimize the parts where the spread of the cooling liquid is not possible. The thickness of the effect layer of the rapid cooling of the base F is thus made nearly the same about the thicknesses of the other three surfaces L, N, S and the generation of the transverse crack at the time of the hot rolling is completely obviated.
