摘要:
A pickling plant for a steel strip and a method for controlling the pickling plant, including monitoring at least one quantity of state represented by thickness, width and quantity of scale of the steel strip, and at least one quantity of state of operation of a plant represented by concentration, quantity and temperature of acid supplied into a pickling tank of the pickling plant, line speed of the steel strip, and temperature of the steel strip immediately before entering the pickling tank calculating on the basis of values of said quantity of state and quantity of state of operation, at least one of concentration distribution of acid, concentration distribution of iron and descaling rate at optional plural positions, and on the basis of the calculating the optimum quantity of state for operation of the plant is determined.
摘要:
This invention relates to an improved apparatus and method for electrolytic descaling of steel strips. The apparatus comprises electrodes integrated with nozzles having jet openings for dispensing electrolyte onto the surface of the steel strips. By jetting the electrolyte to the steel strip in the air and applying a voltage to the electrode, the scale on the surface of the steel strip is removed. This jetting of electrolyte reduces the size requirement of the electrolyte tank storing the electrolyte because the required quantity of electrolyte decreases. The present invention does not require immersion of the electrodes in the electrolyte and thus avoids the problem of short-circuiting that occurs with submerged electrodes. This results in a significant improvement in electric power efficiency. By individually adjusting the jet pressure of the electrolyte jets, the waving and the flexure of the steel strip is prevented and the electrodes can be arranged close to the steel strip to reduce required electric power. With the reduction in short circuit currents, many electrodes can be provided and the speed of the descaling can be increased as a result of the increase in electric current to the steel strip.

A multilayer circuit board for a coordinate detecting apparatus has a sensor region having X-coordinate sensor lines which are equidistantly arranged in parallel and Y-coordinate sensor lines which are also equidistantly arranged in parallel; a processing circuit is in a periphery of the board. A first layer has signal lines which constitute the processing circuit. A second layer has grounded dummy sensor lines in a position corresponding to the signal lines on the first layer. The X and Y dummy sensor lines intersect to form mesh grounds on the second layer and cover the signal lines. Optionally, the mesh grounds are formed on a third layer, and the first layer is sandwiched between the second and third layers. The dummy sensor lines or the mesh grounds substantially block propagation of noise produced by the circuit board and help increase the size of the sensor region effective area.
摘要:
Sparkling low alcoholic beverage sake having light turbid, high transparent, refreshing and superior flavored properties, and the producing method thereof are provided. Steamed rice and malted rice (koji) are saccharified and fermented in the presence of multiple acids to produce low alcoholic unrefined sake (moromi). A part of the unrefined sake (moromi) is filtered through coarse mesh filter to separate turbid liquid containing yeast and having fermentation activity. The other part of unrefined sake (moromi) is pressed to separate clear transparent liquid. The turbid liquid and the clear transparent liquid are mixed and blended, then bottled. When the inner gas pressure in the bottle reaches 2-5 kg/cm2, the fermentation is terminated.
