摘要： PURPOSE:To obtain the title alloy having excellent oxidizing resistance and cracking resistance and having small compressive creep strain at low cost by specifying the compsn. consisting of C, Si, Mn, Cr, Ni, Fe, W and Co. CONSTITUTION:The heat-resistant alloy for a hearth member contains, by weight, =0.5% W together with Mo in the range of 0.25-3% Mo+1/2W or 0.001-0.02% B and the balance consisting of Co with inevitable impurities. The alloy has extremely excellent heat resistance, and its cost is lowered by the reduction of the used amounts in Co. The capacity and durability of a heating furnace can be improved in the use of said alloy.

摘要： PURPOSE:To provide a skid button having an excellent heat insulation characteristic and high-temp. compressive creep strength by forming the outside periphery in the corner part at the bottom end of a heat resistant alloy over the entire surface thereof and forming the remaining part of a heat resistant alloy into which ceramic grains are dispersed and incorporated. CONSTITUTION:The skid button 1 is attached by welding to a pedestal 3 welded atop a skid pipe 2. The bottom end of the skid button 1 is formed of the heat resistant alloy 4 to permit welding and the remaining part is formed of the heat resistant alloy 5 into which the ceramic grains are dispersed and incorporated. The ceramic grains having about 1-5mmphi grain size are used and the content thereof is preferably about 50-80% ratio by volume. The skid button 1 which has the excellent impact resistance and is free from the ceramic wear by reaction is thus obtd.

摘要： PURPOSE:To provide superior heat insulating properties, superior compressive creep strength at high temp. and superior shock resistance to a skid button, to enable the welding of the button to a skid pipe and to facilitate attachment by entirely coating the outside of the support base of the button made of ceramics with a metal to the required thickness. CONSTITUTION:The outside of ceramics 1 forming the support base of a skid button is entirely coated with a metal 2 to 0.5-2cm thickness. A Co alloy or a heat resistant alloy such as HS21, UMCo5, or S816 is used as the metal 2.

摘要： PURPOSE:To improve stably various properties such as wear resistance, creep- resistant characteristic, heat insulating characteristic, workability and strength by limiting the average size and volumetric packing fraction of the ceramic particles of a composite material formed by dispersing uniformly the ceramic particles into the matrix of a metal. CONSTITUTION:The ceramic particles 5 such as alumina particles having >=1mm average size are charged into a partition chamber 6 and the metal 3 for forming matrix such as heat resistant Co alloy is packed into a vessel 4. Electricity is conducted to a high-frequency coil 10 to melt the metal 3. The volumetric packing fraction of the particles 5 in this stage is made 15-85%. The metal 3 in the molten state enters the inside of the chamber 6 through apertures 7 in the lower part on the side wall of the chamber 6 and is gradually infiltrated among the particles 5 by the own weight or the pressurization of the liquid surface until the metal is finally spread to all part in the chamber 6. The always stable high performances mentioned above are exhibited by the above-mentioned constitution and therefore the above-mentioned composite material is adequate as a wear-resistant member for various machines, structures, etc.
