摘要： PURPOSE: To prevent a wrong operation of a factory operator and simplify operations by determining the staritng order of equipment and its operation range in a sintering shop in automatic mode based on an operating condition which determines the staritng ranee and starts accordingly the equipment in the sintering shop in continuous mode. CONSTITUTION: Whether the raw material is loaded or not is determined based on tracking data of a raw material cut down from a mineral storage tank 1 as for a raw material system 19 and the information of a sintering machine 6 is determined based on tracking data of a raw material cut down from a drum feeder 4 in automatic mode. The presence of gas water sealing of an ignition lamp 5 and the operating conditions of a main blower 15 during its operation and suspension is also determined with a sensor in automatic mode. As for the operation conditions of the raw material system 19, the starting method of equipment demands for starting every equipment at a stroke in the case of loading while it demands for staritng in order the equipment from the upstream to the downstream in the case of empty loading. This construction makes it possible to prevent a wrong operation of an operator and dispense with a skilled technique of the operator.

摘要： PURPOSE:To provide a charging method for sintering raw material, in which the raw material for sintering machine is stably charged so as to eliminate rugged surface and to improve the quality and the gas permeability of sintered ore. CONSTITUTION:In the charging method for sintering raw material adjusting the opening of a sub-gate 3 in the charging device by detecting piling state 15 on an inclining surface for sintering raw material 20 which is charged on a pallet 16 by using a chute 4, the charged layer thickness 13 of the sintering raw material, which is charged on the pallet 16 at the downstream side of the chute 4, is detected. When the detected value is short of the setting aimed value, the opening of the sub-gate 3 in the charging device is adjusted to increase the aimed value of the piling state. By this method, the gas ignitability is improved and the yield due to uniform sintering is improved, and the quality of cold strength, etc., of the sintered ore and the gas permeability at the time of sintering the raw material can be improved.

摘要： PURPOSE:To control the raw material density in the transverse direction of a sintering pallet and to improve the product yield of sintered ore for a blast furnace by detecting the raw material density on the pallet, comparing the same with a set density and controlling the opening of divided gates of a drum feeder at the time of producing the sintered ore with a DL type sintering machine. CONSTITUTION:A raw material feeding gate 3 is formed of >=3 pieces of the divided gates 4 and gamma ray density meters 7 are inserted into the packed raw materials on the pallet corresponding thereto at the time of feeding the sintering raw material in a charge hopper 1 of the DL type sintering machine and igniting the material to sinter the same. The raw material density in the transverse direction of the pallet detected by the density meters 7 is inputted to a signal processor 8 which compares the number of the gamma ray counts determined by the same and the difference of the packing density in the transverse direction of the sintering pallet from a setting board 10 for the difference of the packing density in the transverse direction of the pallet. The opening of the divided gates 4 is so adjusted by a control device 11 to adjust the difference equal to the set density difference. The thermal hysteresis at both ends in the transverse direction of the pallet is uniformized over the entire part in the transverse direction, by which the sintering yield of the packed raw material is improved.

摘要： PURPOSE:To improve air permeability of a sintered raw material and to produce sintered ore having excellent reducibility in the stage of producing the sintered ore for a blast furnace by pelletizing pulverous iron ore and powdery lime with coarse granular iron ore as a nucleus and using the pellets in conjunction with a main raw material. CONSTITUTION:The main raw material 4 for the sintered ore is gurried from each storage tank and is charged into a primary mixer 7 and is mixed. The pulverous iron ore 1 contg. >=70% =1 or 2 kinds among limestone, quicklime and slaked lime having =1.0wt% of the sintered raw material. The limestone powder, etc. are used at >=0.5wt% thereof. The coarse granular ore such as the sintered returns of the blast furnace as the nucleus for pelletization is used at a ratio of 20/80-60/40 with respect to the total weight of the pulverous ore and the limestone. Such pellets 6 are mixed with the main raw material mixture from the mixer 7 in a secondary mixer 8. The sintering raw material having excellent air permeability is thus obtd.

摘要： PURPOSE: To provide a method for adjusting productivity of a sintering machine by which production by the sintering machine is adjusted to a target value while keeping inventory level in a charging hopper at a proper level. CONSTITUTION: Total amount of the material to be sintered extracted from respective storage tanks 1 is adjusted so that the inventory level in the charging hopper of the sintering machine 5 periodically approaches a target value, and further, speed of the sintering machine 5 is adjusted at a longer period than a period at which inventory level in the charging hopper is adjusted according to the difference between a target production and an actual production of sintered ore. In such a manner, productivity of the sintering machine 5 can be adjusted to the target value while stably keeping the inventory level in the charging hopper at a target value and avoiding disturbance of calcine caused by frequent changes of speed of the sintering machine 5.

摘要： PURPOSE:To measure the density of the surface-layer part of a sintered raw material loaded onto a pallet without contacting the sintered raw material. CONSTITUTION:A sintered raw material density meter 1 with one gamma ray source 2, a screen 3, and two gamma ray detectors 4 and 5 which are laid out at different positions is installed at a proper distance from a surface-layer part 7 of the sintered raw material. Gamma rays 6 are applied from the sintered raw material density meter 1 to the surface-layer part 7 of the sintered raw material and then the gamma rays 8 scattered by the surface-layer part 7 are counted for a certain amount of time by the two gamma ray detectors 4 and 5. Simultaneous equations with the density of the surface-layer part 7 and the distance from the density meter 1 to the surface-layer part 7 as unknown values are solved with the count as an input, thus measuring the density of the sintered raw material even if the layer thickness of the sintered raw material on the pallet changes.
