Title: Attachment for hydraulic shovel
Inventor: YAMADA MASAO
IPC: E02F3/36
Filed: 1994-12-26
Abstract: PURPOSE: To enhance the safety, by providing a hydraulic oil supply system for separating the distance between the movable claw and the fixed claw or closing it, in the cylinder for the control thereof and providing a cut-off valve in the hydraulic oil supply system for separation to usually keep it in the cut-off condition. CONSTITUTION: When a bucket is attached, the fixed claw of the attachment is hooked at one of the bucket pins of the bucket. Next, the claw 233 of movable claw 23 is positioned to the other bucket pin. Then, an operating switch is put on to open an electromagnetic cut-off valve 25 and to supply hydraulic oil for separation of the claws to the hydraulic cylinder 24. After the claw 233 has been hooked at the bucket pin to fix to the bucket, the valve 25 is held closed. The hydraulic oil pressure in the cylinder 24 is kept by the valve 25 as long as the operating switch is not put on and the movable claw 23 is never loosened even though the hydraulic pipes would be broken. Moreover, even when the bucket is operated to remove by mistake, the valve 25 keeps out the hydraulic oil from the cylinder 24. In this way, the falling accident of the bucket can be prevented.

Title: Refractory for adsorbing and removing inclusion in molten steel
Inventor: YAMAMURA HIDEAKI
IPC: C04B41/87
Filed: 1989-12-28
Abstract: PURPOSE:To remove the inclusion of molten steel and to improve the quality of a product by applying a thin layer of CaF2 coating material on surface of lime quality refractory. CONSTITUTION:CaF2 is applied on surface of the lime quality refractory, and alumina powder is put on the surface, and by heating the refractory at and for the prescribed temp. and time, a large quantity of alumina is absorbed into the lime quality refractory. Coating material 5, weir 6, granular refractory for addition and plate-like refractory of a tundish 1 formed by applying the coating material containing CaF2 as an essential component on the surface of lime quality refractory (w) efficiently remove the inclusion in molten steel by coming into contact with the molten steel. Then, the thickness of the coating material should preferably be a specified thickness and if it is thin, the above effect cannot be expected and on the contrary, if it is thick, the coating may be molten down and becomes the inclusion. Adsorbing quantity of alumina into the lime refractory becomes more, as the CaF2 content in the coating material is higher, but by adding CaF2, the corrosion resistance is lowered. In the case of the coating material, which the corrosion resistance and strength are not required, the upper limit of this content does not exist. By this method, large effect of removing inclusion in the molten steel is obtd. and the cast slab having little inclusion can be produced and the quality of product can be improved.
