Title: Block holder in single-sided lapping machine
Inventor: TAKEUCHI YOSHITOSHI
IPC: B24B37/10
Filed: 1980-08-25
Abstract: PURPOSE:To prevent unsymmetrical wear in a surface plate, by ranging the movement of the contact surface of a work over the whole surface of a surface plate in such a manner that an arm of a roller supporting a block is horizontally swung and the work is reciprocated in the radial directions of the surface plate. CONSTITUTION:A block 29 to which a work is secured, is set in a predetermined position of a surface plate 24, the lateral surface thereof being made contact with the lateral surfaces of supporting rollers 30, 31. The surface plate 24 rotates when a motor is started, and both blocks 29, 29' supported by the rollers 30, 31, 30', 31' also rotate so as to initiate a lapping process. When motors 43, 48 linked to an arm 26 are stated, the roller 30 rotates due to a shaft 39 rotating. Therefore, rotation of block 29 is smoothly performed without irregularity. While when a projecting pin 52 in an eccentric position is made circular movement by a motor 48, a lever 45 swings with a rotating cylinder 28 as its axis, the arm 26 swings in a predetermined range, and the block 29 reciprocates relative to the surface plate 24 in the radial directions, thereby unsymmetrical wear in the surface plate 24 can be avoided.

Abstract: PURPOSE:To enable prevention of explosion of a constructed body of monolithic refractory due to a sudden rise of a vapor pressure inside the constructed body by a method wherein a plurality of hollow pipes having a large number of thin holes are buried on the non-operating surface side of the constructed body, in parallel to an operating surface thereof, and one end of each hollow pipe is opened in the air. CONSTITUTION:On the occasion when monolithic refractory is constructed inside a trough, a plurality of hollow pipes 1 having a large number of thin holes are provided on the non-operating surface side of a constructed body 2, i.e., on the steel shell 3 side, in parallel to an operating surface, and the monolithic refractory is so constructed that one end of each hollow pipe projects from the top surface of the constructed body of the monolithic refractory and is opened in the air. Thereby an excessive moisture in the constructed body is made a water vapor and released into air through the hollow pipes having a large number of thin holes on the occasion when the constructed body is dried by heating and cured, and therefore the constructed body can be prevented from being exploded or cracked by a sudden rise of a vapor pressure. Accordingly, a time for drying by heating and a term of construction of the monolithic refractory can be shortened by increasing the speed of a rise in temperature.
