An apparatus for reading out a radiation image stored on a stimulable phosphor sheet comprises a read-out section, a monitor for reproducing a visible radiation image, an erasing section, and a section for releasably holding a magazine housing stimulable phosphor sheets. The apparatus also comprises a first conveyance system for conveying the stimulable phosphor sheets fed out of the magazine to the read-out section, a stacker disposed at the first conveyance system between the magazine holding section and the read-out section, for housing the stimulable phosphor sheets and transferring them one by one to the first conveyance system. A second conveyance system conveys the stimulable phosphor sheets passing through the read-out section to the erasing section, and a third conveyance system returns the stimulable phosphor sheets passing through the read-out section to the stacker. A distributing member distributes the stimulable phosphor sheets passing through the read-out section either to the second conveyance system or to the third conveyance system.

One of the difficulties in developing a metallic material which is corrosion resistant to caustic alkaline solutions is that the corrosiveness of these solutions is different depending upon the process for producing the same. The chromium alloyed steel developed according to the present invention, contains, from 29 to 31%, of Cr; not more than 3% of Mo; not more than 0.005% of C; at least one element selected from the group of Nb and Ta in an amount, which follows the equation20.times.C(%).ltoreq.Nb(%)+0.5.times.Ta(%).ltoreq.60.times.C(%);from 0.0005 to 0.02% of Ca and; not more than 0.02% of deoxidation products being present in said chromium alloyed steel and essentially composed of CaO, SiO.sub.2 and Al.sub.2 O.sub.3.Because of the combination of the reduction of C, N and the impurities of the steel with the addition of Nb and/or Ta, the corrosion resistance of the chromium steel is excellent with regard to the caustic alkaline solution produced by every kind of processes. This excellent corrosion resistance is not essentially degraded by the welding of the chromium steel pieces and, further, the ductility and workability of the chromium steel are improved.

A slaking property of a lime bearing agent for use in the refining, particularly in the injection refining, of a ferrous melt is essentially eliminated by providing the agent with a special form, i.e. an uncrushed, granular form solidified from molten drops. Hydrogen pick up of the ferrous melt from the refining agent is avoided and an excellent refining effect of the ferrous melt is achieved by the refining agent of the present invention.

A radiation image erase unit for erasing a residual image from a stimulable phosphor sheet with erasure light is disposed in the vicinity of an image read-out unit which converts light emitted from the stimulable phosphor sheet upon stimulation thereof into an electric signal. The radiation image erase unit comprises a box-shaped casing having a slot for passage of the stimulable phosphor sheet therethrough into the casing, and erasure light sources disposed in the casing for emitting the erasure light. A pair of rollers is mounted on the casing adjacent to the slot for introducing the stimulable phosphor sheet into the casing. The casing has reflective inner surfaces for reflecting the erasure light effectively, and a heat radiator for discharging out heat generated by the erasure light sources as they are energized.

The present invention relates to a refining agent used for deoxidation, desulfurization, and dephosphorization of molten steel by a ladle refining, as well as methods for producing such a refining agent. The general practice in ladle refining is to use for the refining agent both so-called flux, which is mainly composed of CaO, and a Ca-based metallic additive.In conventional practice, the flux and the Ca-based metallic additive are added to the molten steel separately.It is an object of the present invention to provide a refining agent, wherein the flux and metallic CaO component act highly effectively on the molten metal.A refining agent for metal according to the present invention essentially consists of: a Ca alloy, which essentially consists of Ca and at least one element selected from the group consisting of Al and Si, and a flux mainly composed of CaO and Al.sub.2 O.sub.3, the Ca-alloy phases and the flux phases being integrally bonded to one another.According to the method of present invention, the reduction of CaO by the metallic reducing agent allows the Ca alloy phase and flux phase to be very uniformly mixed with one another, with the result that the vaporization loss of metallic Ca can be suppressed to a high extent.
