摘要： In the top-and-bottom blown converter steel making process, a process is provided wherein the position of the bottom-blowing tuyeres is set such that the maximum X.sub.0 among the distances X between the respective tuyreres and the center of the converter bottom is up to 1.3 times the horizontal distance Y between the central vertical axis of the converter and the outermost boundary of a hot spot region developed on the molten iron surface by the top-blowing oxidizing gas from the lance. By setting the position of the bottom blowing tuyeres in this manner, the interference of the bottom-blowing gas with the top-blowing gas is promoted to enhance the agitation between the slag and the metal to reduce the concentration of iron value (T.Fe) in the slag, thereby improving the iron yield.

摘要： Spray coating is performed utilizing a mixture of refractory material and a combustionable metal powder. The size of the particle of the metal in the mixture is selected so that the particle size is large enough to be treated safely and is small enough to be transported by means of a gas flow. As a carrier gas for carrying the mixture, a non-combustionable gas or fuel gas is used. A fuel gas and a combustion-assisting gas are discharged toward the section to be treated on the surface for directing a combustioning frame. The refractor material with the carrier gas is discharged into the frame established by the fuel gas and the combustion-assisting gas. The average size of the metal particle to be used in the spray coating is limited to be greater than 50 .mu.m. By enlarging the particle size of the metal, combustion of the metal particle becomes difficult. Combustion of such large particle size metal can be assisted by discharging the combustion-assisting gas together with the fuel gas. This compensates combustion efficiency to be dropped by utilizing the larger particle size metal.

摘要： A spindle motor having a bearing housing and a thrust bearing fitted in the bearing housing at the lower end of the latter, in which an inclined part is formed on the outer peripheral edge at the lower end of the thrust bearing, and the outer diameter part of the thrust bearing is fitted in a coupling bore formed in the end surface of the bearing housing, the end surface of the bearing housing being pressed uniformly in the axial direction over the entire circumference around the coupling bore to cause the bearing housing to plastically flow around the coupling bore in order to cover the above-mentioned inclined part of the thrust bearing. The above-mentioned covering part formed in the bearing housing through plastic flow can exhibit a high bonding strength between the bearing housing and the thrust bearing in the spindle motor without deteriorating the sealing ability of the spindle motor, due to a shearing force and a residual contact pressure of the covering part.
