摘要： A method for spray-working refractory composition solves the problems encountered in conventional dry or wet spraying method. The novel method comprises previously mixing a refractory composition with 1/5 to 3/4 of water necessary for the spray working and adding the rest of water to the mixture in a spray nozzle of a dry spraying gun to mix therein. This method affords a sprayed object with a high density and a high strength of the sprayed layer.

摘要： This invention relates to an apparatus for inspecting the inside of a hot furnace. In an apparatus for inspecting the inside of a hot furnace provided with a camera (1) placed in a case (2) whose inner periphery is cooled by cooling water and to the inside of which cooling air is blown, the present invention disposes sequentially quartz glass (6), heat-ray reflecting glass (7), heat-ray absorption glass (8) and a heat-ray transmitting mirror (9) in the optical path of the rays of light coming from the front surface of the case (2) to the camera (1) and disposes also an illumination lamp (13) on the front surface of the case (2) so as to make remote-control of brightness. In this manner, the inside of the camera case (2) is kept below 50 C, damage to the camera (1) by the heat of radiation from the glass surface is prevented and remote control of brightness of the illumination lamp (13) is made so that the inspection inside the hot furnace can be made at a temperature ranging from normal temperature to 1,200 C.
