摘要： PURPOSE:To stabilize the classification performance of cyclones by providing a mechanism which maintains the water levels in receiving tanks for projected high pressure water and iron sand slurry always constant and maintains a specified concn. of the slurry to be returned to the cyclones. CONSTITUTION:Projected high pressure water and iron sand slurry are received in receiving tanks 3, 3' and the slurry levels therein are detected with level gauges 13, 13'. When the water levels decrease, valves 12, 12' are opened by circuits 14, 15 and 14', 15' to feed the water so that always the specified water levels in the tanks are maintained. Return pumps 20, 20' of constant discharge capacity for low concn. slurry are installed and further detectors 17, 17' for slurry concn. are mounted on the suction side. When the concn. of the inlet side of cyclones by the concn. ratio of the cyclones exceeds a specified value, water supply valves 19, 19' are opened to feed water to prevent the entry of the high concn. slurry exceeding the designed conditions into cyclones 6, 6'.

摘要： PURPOSE:To detect accurately the meandering direction of a sheet in an early stage, by irradiating light to a rolling reduction part of the sheet wrapped around the upper and lower rolls of a differential speed rolling mill, and detecting the amount of light passing through both ends of a gap between both rolls. CONSTITUTION:Light is irradiated toward a gap between rolls 1, 2 from a luminous source 4 provided to one side, a central part at the outlet side for instance on a pass line of a sheet 3 which is running while being wrapped around the upper and lower rolls 1, 2. Image sensors 5, 5' are provided by making their heights adjustable to the opposite side of the luminous source 4 placed on the pass line, both side ends at the inlet side for instance; then wrapping differential-speed rolling is performed while receiving the light irradiated from the source 4 and detecting the amount of receiving light by these sensors. When the opposite side of the meandering direction of the sheet 3 at the inlet side floats from the roll 2 wrapping part as a premonitory sign of the meandering of sheet 3 at the inlet side, the amount of detecting light of the sensor 5 placed at the floating side decreases and that of the sensor 5' does not change. Further, when the sheet 3 at the inlet side deviates to the side end from the center of the gap 6, the same change in the amount of detecting light as mentioned above occurs. Accordingly, the meandering of sheet 3 is leveled and prevented by changing the draft positions at the left and right sides basing on these detected results.

摘要： PURPOSE:To obtain a prescribed concentration of slurry in high efficiency and high accuracy and permit stable scale-removing operation by controlling at least one out of slurry level and stirring speed by feeding grinding material. CONSTITUTION:A concentration (a) of slurry supplied, slurry level (b), and stirring speed (c) are input into a controller 10, and each signal of a slurry concentration setting apparatus 11 and of a memory apparatus 12 related with the slurry concentration and slurry level for each stirring speed is input further, and a stirring-speed adjusting signal (d) and an iron-sand feeding amount adjusting signal (e) are output. The signal (a) of the actually measured value of the slurry concentration is a confirmation signal, and it is not required to be used as control signal. With such an adjusting method, slurry concentration can be adjusted easily. Thus, a prescribed concentration can be secured, and the efficiency of scale-removing operation can be improved.

摘要： PURPOSE:To carry out uniform surface treatment to a strip material, by controlling high pressure water for jetting abrasive, in such a way that the rotational speed of a high pressure water pump is decreased to control a flow control valve in a low pressure range, but the flow control valve is opened to control the rotational speed of the pump in a high pressure range. CONSTITUTION:The open degree of a flow control valve 2 is adjusted in such a condition that the pressure of high pressure water is decreased by limiting the rotational speed of a high pressure motor 4. In a high pressure range B the flow control valve 2 is fully opened so that the adjustment of the open degree of the flow control valve 2 is not made, and therefore, by using a valve having satisfactory flow characteristics for the flow control valve 2, the jetting pressure of high pressure water may be accurately controlled.

摘要： PURPOSE:To obtain a descaled steel strip having surface residue and plating characteristics in the same level as those of a steel plate descaled by pickling, by mechanically grinding the surface of the hot rolled steel strip after blasting a slurry on it, in descaling the strip by wet blasting. CONSTITUTION:In descaling a hot rolled steel strip by blasting a slurry, prepared by mixing water and abrasive grain, while accelerating the slurry with highly pressurized water, the surface of strip just before or after the descaling is ground by a mechanical operation such as buffing, sanding, and brushing, for making up the descaling. Then grinding mark in the surface of strip, caused by the collision between the surface and grinding material at the time of blasting, is improved, and sticking of the grinding material crushed into fine particles is removed. Thus, a steel strip, having surface residue and micro-cross-sectional profile and plating characteristics in the same level as those of a steel strip descaled by pickling, is obtained.
