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 feed mechanically and automatically a pipe for oxygen hole opening into a tap hole by inserting the pipe between a driving roller and driven roller, grasping the pipe by the pressure of the driven roller and turning the driving roller thereby feeding the pipe into the tap hole. CONSTITUTION:A stand 1 is installed near the tap hole of the blast furnace and the pipe 15 for oxygen hole opening is inserted between the driving roller 2 and the driven roller 7 in a casing 8 via guide rollers 18. A screw bar 10 is rotated to press a bracket 6 by a spring 11 (by a cylinder 14 if necessary) so that the pipe 15 is strongly grasped by the driven roller 7 and the driving roller 2. The roller 2 is then rotated to insert automatically the pipe 15 via a guide pipe 17 into the tap hole to be subjected to oxygen hole opening. Oxygen is supplied from a hose connected to the rear end of the pipe 15 into the pipe and the tap hole is opened by the oxidation heat. The inside of the casing 8 is cooled by supplying air from a nozzle 20.

摘要： PURPOSE:To eliminate the overcooling in the initial period of a furnace body and to enable stable operation by cooling the brick of a furnace wall by the evaporation of the cooling water supplied into cooling boxes when the bricks are relatively sound and by the force circulation of the cooling water into the cooling boxes when the bricks are heavily worn. CONSTITUTION:Water is supplied into cooling boxes 4a, 4b, 4c from a high pressure water feed pipe 10 and a specified amt. of the cooling water is stagnated in the pipe 10 in the initial stage of a furnace body when the bricks 2 of the furnace wall are relatively sound. The cooling water in the boxes 4 is gradually evaporated by the heat load born by the bricks 2 and cools the bricks. The steam generated in the boxes 4 is conducted to the pipe 10 and is discharged from a steam release pipe 14. The decreased portion of the cooling water in the boxes 4 is automatically supplied from the pipe 10 by utilizing a head and when the level of the water in the pipe 10 decreases down to a specified level or below, the water is replenished automatically therein. When the steam temp. measured with a thermometer 17 rises to a prescribed temp. or above, that is, when the bricks 2 are heavily worn, the coolng water from a water feed pipe 5 is forcibly circulated into the boxes 4a, 4b, 4c and is discharged into a discharging trough 8.
