IPC: C10B21/10
Filed: 1985-08-05
Abstract: PURPOSE:To reconstruct an oven for repair with minimized drop in production without affecting adjacent ovens and equipment, by decreasing the temp. of an coke oven to a repairing temp. while maintaining the difference in temp. between the oven to be hot recenstructed and repaired, and that of ovens adjacent thereto. CONSTITUTION:When a coke oven is hot recenstructed and repaired, the temps. of ovens A0-B0 to be repaired are decreased from an operating temp., e.g., 1,200 deg., at a rate of 40 deg.-60 deg./day to about 800 deg. while maintaining a temp. difference of 80 deg.-120 deg. between the ovens to be repaired and a series of adjacent oven provided on both sides thereof e.g., A1-A3 on the left side and B1-B3 on the right side.After completion of repair, the temps. of the ovens are raised at the same rate at which the temps. of the ovens have been decreased. Thus, the recenstruction and repair can be made without affecting peripheral ovens with minimized drop in production to such an extent that 3-4 ovens arranged on the right side and left side of the ovens to be repaired are suspended or slowed down.

Abstract: PROBLEM TO BE SOLVED: To improve workability by fixing one ends of connectors to upper and lower grooves formed to a support for coupling a panel and engaging the other ends to a panel body from upper sections and connecting both the panel and the support. SOLUTION: When the upper sections of a panel body 1 and a support 3 are coupled, the engaging sections 10A of an upper-end connector 10 are retained to the upper-lower groove sections 8A of the support 3 and slid downwards, and a vertical plate section 10D hung down from the upper end section of the connector 10 to a lower section is engaged with a hole 1B formed at the upper end of the panel 1. A top cap 5 is fitted at the upper end of the support 3 while pawl sections 5E formed to the cap 5 are fitted into openings among the connector 10 and the groove sections 8A. Since the pawls 5E are formed in a tapered shape, in which wall thickness is thickened towards the upper-end section side, at that time, the panel 1 and the support 3 are joined firmly. An upper cover 4 is fitted at the upper end of the panel 1, and the upper section of the connector 10 is covered. Accordingly, the panel 1 and the support 3 can be connected easily and rapidly without using a bolt, the looseness of a connecting section can be prevented, and cost can be reduced.

The heated plates are rolled and joined at >=70% draft and are then reduced in thickness by rolling at >=400 deg.C if necessary. The rolled plates are subjected to softening annealing at 650-750 deg.C in succession to the rolling. The decrease in strength owing to the brittle intermetallic compd. formed between the Ti and the steel, the embrittlement arising from absorption of hydrogen by Ti and the decrease in the strength arising from the diffusion of C in the steel plate to the Ti plate and the precipitation of brittle TiC are prevented according to the above-mentioned method.

IPC: B25B7/10
Filed: 1995-06-14
Abstract: PURPOSE: To easily change a width of an opening in a clamping part to an optional dimension by arranging shaft supporting bores crank-shapedly. CONSTITUTION: Three or more shaft supporting bores 3 are arranged in an engaging groove 4 in a clamping body 1, and respective bores are crank-shapedly connected to each other by means of grooves each of which is provided with a width narrower than the diameter of the bore, so that in an edge part or edge parts 9 of one side or two sides in the engaging groove 4, circular arcs of the shaft supporting bores 3 continue wave-shapedly. In the engaging groove 4, diameters of the grooves connecting the shaft supporting bores 3 allow a supporting shaft 5 to freely move in the engaging groove 4 when a flat face part of the supporting shaft 5 is matched with the longitudinal direction of the engaging groove 4 and the clamping parts 6, 7 are opened. However, the supporting shaft 5 is temporarily stopped in a crank part 8, as the engaging groove 4 is formed crank-shapedly.  Therefore, a dimension of an opening between the clamping parts 6, 7 can be adjusted while preventing the supporting shaft 5 from moving directly from the bore 3 in the end part of the engaging groove 4 to the bore 3 in the other end part.
