    摘要: A roll bending apparatus for use in a multi-stage rolling mill adapted for rolling a hard material or a thin sheet material with a high uniformity of thickness along the breadth, with a high degree of accuracy and low energy. The rolling mill has work rolls of a comparatively small diameter. The amount of bend of the small-diameter work roll is controlled by the roll bending apparatus for attaining the high degree of uniformity of thickness along the breadth of the rolled material. The roll bending apparatus has, for each of said work rolls, a supporting member having a work roll supporting portion for rotatably supporting the work roll and rockable vertically about a fulcrum, and a bending force generating means adapted for engaging the supporting member so as to cause a rocking motion of the supporting member thereby applying a substantially vertical roll bending force to the work roll through the supporting member.

    摘要: An apparatus for drain-casting a slip comprises a mold including at least two divisible mating mold portions to form a mold cavity, a slip tank, a pump, air compressors, suction pumps, valves and tubings to connect them accordingly, supporting means of the mold portions, and a moving stand to receive the molded article thereon. The mold portion includes an air-tight vessel and a filter member inside the vessel, the filter member contains a water-drainage means, and the drainage means is communicated with the outside of the vessel. One of the mold portions has a slip supply duct and one other mold portion has an overflow duct, which ducts are communicated with the outsides of the vessels. A method using such apparatus to form hollow ceramic or porcelain ware comprises pressurizing a slip introduced into the mold cavity and preferably depressurizing the water-drainage means to deposit the slip onto the filter members, draining an undeposited slip through the slip supply duct, removing one of the mold portions by applying compressed air to the water-drainage means of the mold portion to exude some water between the filter member and the resulting molded article, depressurizing the water-drainage means of the other mold portion to attract the molded article into the mold portion, hanging the molded article attracted into the mold portion, applying compressed air to the water-drainage means as described above, and thus demolding the molded article on the stand safely.

    摘要: A continuous rolling mill has horizontal roll stands and vertical roll stands disposed alternatingly with rolling guides between the work rolls of adjacent roll stands. The roll stands together with the rolling guides are movable in the direction crossing the rolling line to an exchanging position where the work rolls and the rolling guides are exchanged with new ones. The continuous rolling mill further has a supporting frame supporting the roll stands and movable to the exchanging position thereby to bring the roll stands and rolling guides to the exchanging position, and an offsetting device adapted to move one of the adjacent roll stands relatively to the other of the adjacent roll stands and to the frame in the exchanging position such that the rolling lines of the adjacent roll stands may be offset from each other. This arrangement permits a reduction of the pitch or interval of the roll stands and affords a quick exchange of the rolls and rolling guides with new ones, contributing greatly to the reduction in installation space and cost while improving the efficiency of rate of operation of the rolling mill advantageously.
