摘要： PURPOSE:To adjust adequately the depth of a tap hole and to execute stable tapping and slag discharge operations by providing a blast control valve to a blast branch pipe of a tuyere positioned upper than a tap hole and adjusting the flow rate of hot wind. CONSTITUTION:The blast control valve 7 is provided to a blast branch pipe 6 for supplying hot wind to the tuyere 3 positioned upper than the tap hole 2 of a blast furnace 1. The opening degree of the valve 7 is decreased to decrease the flow rate of the hot wind when the depth of the hole 2 is lower than the prescribed value. Then the flow of the gas near the hole 2 is made inactive by while the slag, etc. sticks to the hole 2 and the depth of the hole 2 is increased. The opening degree of the blast control valve is increased to increase the flow rate of the hot wind when the depth of the port 2 is higher than the prescribed value. Then the flow of the gas near the hole 2 is made more vigorous by which the slag, etc. sticking to the hole 2 are stripped and the depth of the hole 2 is decreased. The level of the molten iron 9 and slag 10 in the hearth 4 is thus made uniform and the tapping operation is continued without clogging the hole 2.
摘要翻译：目的：充分调整龙头孔的深度，并通过向位于上方的风口的鼓风支管提供爆炸控制阀，并调节热风流量，从而执行稳定的排渣和排渣操作。构成：将喷气调节阀7设置到用于向位于高炉1的排气孔2上方的风口3供给热风的鼓风分支管6.阀7的开度减小，当孔2的深度低于规定值时的热风。然后，当孔等附着在孔2上并使孔2的深度增加时，孔2附近的气体流动变得无效。当端口2的深度高于规定值时，鼓风控制阀的开度增加，以增加热风的流量。然后使靠近孔2的气体的流动变得更加剧烈，通过该气流使粘附到孔2的炉渣等被剥离，孔2的深度减小。因此炉底4中的铁水9和渣10的水平均匀，并且继续敲打操作而不堵塞孔2。

摘要： PURPOSE:To permit the effective utilization of a wet type blast furnace dust by a method wherein spigot accumulated in the lower part of a waste water pit is blown into the furnace from respective tuyeres of the blast furnace by controlling the concentration of slurry. CONSTITUTION:Washing water from the cleaning equipment of a blast furnace is recovered to a waste water pit 6 through a pipe line 11 and is effected natural sedimentation, therefore, they are separated to supernatant liquid 12 and the spigot 13 containing the blast furnace dust. The spigot 13 is drawn up by a waste water pump 4 and the concentration of the slurry is controlled by 30% by a moisture control device 8, then, it is sent to a mixing device 9 while the slurry is stirred in order to prevent to become impossible to send the liquid due to sedimentation of the blast furnace dust contained into the liquid, next, it is blown to the blast furnace from respective tuyeres 14 through the distributing device 10 of the slurry. According to this method, the wet type blast furnace dust is treated easily, moreover, it can utilize as effective iron source and heat source. Further, it is blown together with water to the blast furnace, therefore, it can use instead of humidity conditioning steam and may be effected the rationalization of the blast furnace.
摘要翻译：目的：通过控制浆料浓度，通过将积水在废水坑下部的塞子从高炉各风口吹入炉内的方法，可以有效利用湿式高炉粉尘。构成：将来自高炉清洗设备的洗涤水通过管道11回收到废水坑6，并进行自然沉淀，因此将其分离成上清液12和含有高炉粉尘的插口13。插管13由废水泵4拉出，并且通过湿度控制装置8将浆料的浓度控制30％，然后将其送入混合装置9，同时搅拌浆料以防止由于包含在液体中的高炉灰尘的沉降而使液体变得不可能，接着从各个风口14通过浆料的分配装置10吹送到高炉。根据该方法，可以容易地对湿式高炉粉尘进行处理，而且可以用作有效的铁源和热源。此外，与水一起吹入高炉，因此可以代替调湿蒸汽，可以实现高炉的合理化。

摘要： PURPOSE:To prevent the trouble in the revolution of a valve shaft due to the coagulation of hot wind in a chamber by connecting the chamber formed between the valve shaft and the flange of a casing to a drain discharge part through a passage formed onto the flange. CONSTITUTION:In a flow-rate control valve, a valve body 2 is rotatably arranged into a casing 3 on which a flow passage is formed from heat-resisting material. The chamber A formed between the valve shaft 22 of a valve body and the flanges 33 and 35 of a casing 3 is connected to a drain discharge part 6 through a passage formed onto the flange. Therefore, even if the hot wind containing solvents, carbon powder, etc. intrudes into the chamber A from the gap (g) formed between the valve shaft 22 and the heat-resisting members 36, 36a, 37 and 37a, said hot wind is discharged outside, passing through the valve 62 in the drain discharge part 6, and coagulation or the formation of rust in the chamber A is prevented.
