摘要:
The present invention provides an oven-width measuring apparatus which does not require any cooling water pipe so that the oven-width of a high temperature oven chamber such as a coke oven chamber can be measured rapidly and easily, and which is capable of resisting a high temperature during the time necessary for it to be in the oven chamber for the measurement. The oven-width measuring apparatus is used for measuring the distance between oven walls facing each other of an oven chamber, that is to say, the width of the oven chamber, and comprises a measuring unit 2 which includes an oven-width measuring instrument 8 and a power supply unit 10, and is accommodated in a endothermic box 3 the outside of which is covered with heat insulating material 4. The endothermic box 3 is a jacket filled with liquid 7 having endothermic ability, and the liquid 7 is preferably water. The measuring unit 2 also includes a data-recording unit 9, or a wireless transmitter 18 for transmitting the data of the measured oven-widths to an external data-recording unit 22. The endothermic box 3 is provided with an outlet, at the bottom thereof, from which the liquid 7 is discharged.

An object is to provide coke having a high strength and excellent extrusion capability from a coke oven and a method for manufacturing the coke. In addition, provided is a method for quantitatively evaluating homogeneity of a coal blend. Using a mixing apparatus having a capability of controlling a degree of mixing to be 0.85 or more at 60 seconds after the start of a mixing and stirring operation when stirring and mixing a coal blend makes it possible to disintegrate pseudo-particles in the coal blend in order to homogenize the coal blend. Therefore, it is possible to manufacture coke excellent in terms of coke strength and extrusion capability. The degree of mixing is defined by equation (1): degree of mixing = ÃC 0 ˆ’ ÃC / ÃC 0 ˆ’ ÃCf Here, the degree of mixing is a value calculated from the standard deviation of characteristic values respectively determined for the samples taken from the stirred and mixed coal blend. ÃC 0 denotes the standard deviation of a characteristic value when mixing is not entirely performed, ÃCf denotes the standard deviation of characteristic values when mixing has been completely performed, and ÃC denotes the standard deviation of respective characteristic values of the samples taken.

摘要:
An oven wall three-dimensional profile data (701) representing concave and convex amounts on all over oven walls (14R, 14L) at a right side and left side of a coking chamber (11) is generated by using image signals obtained by a wall surface observation apparatus (200). A resistance index "k" in which a resistance received by pushed coke (15) resulting from a rising gradient existing on the oven wall (14) is indexed is asked by using the oven wall three-dimensional profile data (701). It can be verified that there is a correlation between this resistance index "k" and a pushing load. Accordingly, it is possible to quantitatively evaluate a state of the oven wall (14) affecting on the pushing load.
