摘要： PURPOSE:To obtain unburned magnesia-carbon brick excellent in oxidation resistance without causing a rise in thermal stress and deterioration in corrosion resistance. CONSTITUTION:A method for producing unburned magnesia-carbon brick is characterized in that boron-modified novolak type phenolic resin prepared by modifying a novolak type phenolic resin with boron or boron oxide is added to 100wt.% blend of 3-40wt.% carbon and the remainder of magnesia clinker as principal materials and the resultant mixture is kneaded and then formed. No skew breaking is present at all in the magnesia-carbon brick produced by this invention and the formation of a decarbonized layer near the operating surface is extremely rare. As a result, excellent corrosion resistance held by the magnesia-carbon brick is satisfactorily exhibited and use durability remarkably improved as compared with that of conventional materials is obtained a obviously from the results of the aforementioned actual machine tests.

摘要： PURPOSE:To control the subject coal supply so that formed coal for production of uniform coke may be obtained by classifying crushed and dried coal, weighing the classified coal, determining the deviation between the mixture weight ratio calculated therefrom and the target value and controlling the classification point based on the resultant value. CONSTITUTION:Coal (C) piled up in the yard (Y) is stored in a mixing tank 1, crushed by a crusher 2 and then classified into fine particle coal and coarse particle coal using a drying and classifying machine 4. Formed coal is produced from the above- mentioned fine particle coal using a pressure forming machine 10 and the resultant formed coal is blended with the coarse particle coal in a prescribed ratio. The blended coal is charged into a coke oven and production of coke is carried out. In the above- mentioned processes, the coal supply to the pressure forming machine 10 is controlled by measuring the respective weights of the fine and coarse particle coals classified by the classifying machine 4 using a gravimeter 16, comparing the measured mixture weight ratio calculated from the above measured values with the target weight ratio value, determining the deviation between both the values and controlling the classification point of the classifying machine 4 based on the resultant deviation value.

摘要： PURPOSE:To mechanize the manually operated coke-digging work of a horizontal chamber coke oven in case of oven clogging or mending of oven wall. CONSTITUTION:A heat-resistant conveyor 5 is extended perpendicular to the length of an oven group on the bottom part of a vehicle 1 freely moving in front of coke ovens along the length of the oven group. A gyration member 6 freely rotatable around a vertical shaft is placed on the vehicle 1. A boom 7 freely rotatable around a horizontal axis is attached to a part of the gyration member 6, an arm 8 is connected to the other end of the boom 7 in a state freely rotatable around a horizontal axis and a bucket 9 is connected to the other end of the arm 8 in a state freely rotatable around a horizontal axis. A scattering prevention plate 17 is placed on the vehicle 1. The dug red-hot coke is safely transferred to a quenching vehicle or a bucket vehicle while preventing the scattering of the coke without necessitating the approach of a worker to the red-hot coke. The worker is relieved from heavy muscular labor and the digging work can be carried out with a small number of workers in a remarkably shortened time.
