摘要:
The invention provides a modified protease such that a protease is coupled to a polysaccharide via a triazine ring. This modified protease is considerably stable, safe and active as compared with the conventional modified proteases and immobilized proteases. Therefore, cosmetic products containing this modified protease are less liable to undergo aging, easier to use and improved in effect on the skin.
摘要:
A continuous casting method of molten metal using electromagnetic force to improve the cast slab surface properties and reduce the nonmetallic inclusions and bubbles trapped inside the cast slab is provided. An alternating current is run through an electromagnetic coil arranged around a casting mold so as to surround a casting space to control the meniscus shape to improve the cast slab surface properties. The discharge ports of a submerged entry nozzle are oriented upward and the direction of the discharge flow from the discharge ports is above the intersection of the casting mold short side and meniscus.

In a insert-type continuous casting nozzle comprising a highly functional layer formed to have a high corrosion resistance, a high anti-attachment capability, etc., and provided to define an inner bore thereof, the present invention is directed to providing a refractory material (mortar) for an intermediate layer of the continuous casting nozzle, which has a property capable of fixing an inner bore-side layer to an outer periphery-side layer (a nozzle body) of the continuous casting nozzle, while preventing the occurrence of expansion splitting in the outer periphery-side layer due to a difference in thermal expansion between the inner bore-side and outer periphery-side layers, and a continuous casting nozzle using the refractory material for the intermediate layer. The refractory material for the intermediate layer contains a hollow refractory aggregate in an amount of 10 to 75 volume %, wherein a ratio of an average radius R of each particle of the aggregate to an average wall thickness t of the particle satisfies the following relation: R/t≧10. This refractory material is disposed between an inner bore-side layer (2) and an outer periphery-side layer (3, 4) of a continuous casting nozzle.

Disclosed is a continuous casting nozzle having a refractory portion formed to contain a dolomite clinker and arranged to define a surface region adapted to be in contact with molten steel, which is capable of protecting a working surface of the nozzle from alumina build-up due to alumina in molten steel, while improving corrosion resistance, even during long-term continuous casting of molten steel. The refractory portion is prepared by adding a binder to a mixed material and subjecting the obtained mixture to kneading, forming and heat treatment. The mixed material comprises a dolomite clinker which has an average particle size of 0.8 mm or less and a CaO content of 50 mass % or less. The mixed material has a ratio W1/W2 of 0.33 or more, wherein W1 is a content by mass of CaO, and W2 is a content by mass of MgO. The mixed material comprises a dolomite clinker and a magnesia clinker. Alternatively, the mixed material comprises a dolomite clinker and a magnesia clinker. The mixed material has a ratio WD/WM in the range of 0.5 to 15, wherein WD is a mass % of dolomite clinker particles having a particle size of 1 mm or less in a particle size distribution of the dolomite clinker, and WM is a mass % of magnesia clinker particles having a particle size of 1 mm or less in a particle size distribution of the magnesia clinker. Further, the mixed material has a ratio W1/W2 in the range of 0.33 to 3.0, wherein W1 is a content by mass % of a CaO component in the dolomite clinker, and W2 is a content by mass % of an MgO component in the magnesia clinker.
摘要:
A temperature measuring device, which is used in a continuous casting machine, measures the surface temperature of a part or all of a cast slab in a width direction of the cast slab, which is drawn from a mold and conveyed by rollers, in a secondary cooling zone of the continuous casting machine. The temperature measuring device includes a support member that is installed on the side of roller support parts by which the rollers are rotatably supported; an arm member of which a proximal portion is rotatably mounted on the support member; and a radiation thermometer which is provided at a distal end portion of the arm member and of which a light receiving opening is disposed at a position corresponding to a height in the range of 1.0 to 4.5 m from the surface of the cast slab.
