摘要： PROBLEM TO BE SOLVED: To provide a shape steel cutting method, by which a cut surface having a good shape and excellent smoothness can be produced at all times with excellent reproducibility and a cutting load can be reduced. SOLUTION: In the shape steel cutting method in which shape steel composed of a flange and a web is supported by a fixed blade and is cut by feeding a traveling blade having a flange-cutting blade and a web-cutting blade in the tilting direction with respect to the flange in a plane perpendicular to the longitudinal direction of the shape steel, the tip of the web-cutting blade comes into contact with the surface of the web and starts to cut the web with the cut-off speed more than 0.20 m/s when a depth of cut of the flange-cutting blade has exceeded 45% of the thickness of the flange.

摘要： PURPOSE: The titled machine capable of pushing out coke almost continuously with preventing the abrupt decrease in the pressure of the top of a furnace, only making a fan-shaped table reciprocate horizontally in the radius direction of the main body of a quenching furnace so that given amounts of coke are taken out.
CONSTITUTION: The fan-shaped tables 38W41 are arranged respectively below the plural opening parts 33W36 of an intermittent loop ordination which is formed by both the cylindrical distributor 31 set at the central position of the end opening part of the main body 30 of an quenching furnace and the opening edge 32A of the end of the main body of the quenching furnace. Each of the fan-shaped tables 38W41 is capable of reciprocating horizontally and freely in the radius direction of the main body of the quenching furnace through the rails 45 and the wheels 44, and when the fan-shaped tables 38W41 are reciprocated successively, given amounts of coke are taken out from the opening parts 33W36 successively.

摘要： PURPOSE:In a dry extinguishing furnace for coke, the secondary cooling gas is blown from the undermost part of the gas-blowing funnel in the cooling chamber to extend the cooling zone, thus enabling the contraction of the volume of the cooling chamber, resulting in increase in the cooling efficiency of the dry extinguishing of coke. CONSTITUTION:In a dry extinguisher for coke, the first cooling gas inlet 12 is formed with funnels 11 and 11a beneath the furnace 10. The circulation gas is heat exchanged, sent through a ring pipe 13 and the inlet 12 into the chamber and distributed by the distributor 15 on the center, thus cooling the red-heated coke in the furnace. Then, the secondary cooling gas is blown in through another inlet 22 for the secondary cooling gas at the undermost end of the funnel 11 and/or through the third inlets 23 on the upper hopper 18 which is placed beneath the funnel 11. The cooled coke is cut out by the cutting gate 17 into the upper hopper 18 and sent out to the lower hopper 20 by opening the upper trap 19.
