Title: Production process of monolithic refractory block using used refractory material as coarse aggregate
Inventor: TSUTSUI KOJI
IPC: C04B35/66
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a production process of a monolithic refractory block using a used refractory material as coarse aggregate, which involves mixing, as coarse aggregate of the block, a large amount of a nonmagnetic material in the used refractory material into a base mix for the monolithic refractory block, in order to avoid influence of the porosity and composition of the used refractory material and uniformly dispersing the coarse aggregate within the monolithic refractory block, and thereby enables enhancement of properties such as dissolution loss resistance and strength of the refractory block, reduction in amount of such a used refractory material to be disposed as waste and also reduction in refractory material cost. SOLUTION: This production process of the monolithic refractory block comprises: crushing a used refractory material; subjecting the crushed used refractory material to magnetic separation; thereafter mixing, as coarse aggregate 14, a nonmagnetic material which is separated from the crushed used refractory material and has 5-60 mm grain size, into a base mix for the refractory block in an amount sufficient to provide a 30-55 wt.% ratio of the nonmagnetic material to the resulting refractory block; wherein more specifically, the coarse aggregate 14 is charged into a form 13 beforehand, and then, the spaces among the grains of coarse aggregate 14 are filled with a slurry 15 obtained by adding water to a refractory raw material containing a hardening agent and a dispersant and mixing them together.

Filed: 2001-02-13
Abstract: PROBLEM TO BE SOLVED: To estimate not only a depth of a decarbonized layer in ferrite but also a depth of the whole decarbonized layer. SOLUTION: The depth of the decarbonized layer is calculated based on a decarbonization model corresponding to a low temperature area where decarbonization in the ferrite is generated from a substantial surface of a steel material to a depth ξ, an intermediate temperature area where the decarbonization in the ferrite is generated from the substantial surface of the steel material to the depth ξ, and where decarbonization in austenite is generated in a zone deeper than the depth ξ, or a high temperature area where the decarbonization in the austenite is generated from the substantial surface of the steel material. A property that a decarbonization concentration comes to c0, Calpha, or Cgamma in the depth ξ of the ferrite decarbonized layer is used in the calculation hereinbefore.

Abstract: PROBLEM TO BE SOLVED: To guide light to an indicating part 41 without degrading appearance by disposing a light receiving part 42 on the back side of a dial 2, in a speed meter 1 being a luminous pointer instrument. SOLUTION: The pointer 4 of the speed meter 1 is composed by assembling two components such as the indicating part 41 extended along the front side of the dial 2, and the light receiving part 42 for entering the light from a light emitting diode 6.

The diameter D1 of a through hole of the dial 2 for inserting a shaft part 41a of the indicating part 41 is set smaller than the diameter D2 of an incident surface 43 of the receiving part 42. Thereby, when the dial 2 is seen from the front side, the receiving part 42 of the pointer 4 can not be seen by being blocked by the dial 2, and only the indicating part 41 can be seen, so that the appearance is improved.  The indicating part 41 can be mounted to the receiving part 42 by inserting it into the through hole 2a from the front side of the dial 2, so that the mounting workability of the pointer instrument can be improved.
