Title: Metallurgical refractory composition
Inventor: IMAGAWA HIROSHI
IPC: C04B35/48
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To enable dense packing of refractory aggregate particles to suppress the infiltration of slag, or the like, improve the melt damage resistance of the refractory and prolong the life by compounding a refractory aggregate containing a specific amount of ZrO2 or MgO together with graphite in a manner to attain a specific variation coefficient. SOLUTION: A metallurgical refractory composition containing graphite is compounded with a refractory aggregate in a manner to get a variation coefficient α defined by σ/X of 0.01-1.0, preferably 0.2-0.95 or thereabout wherein σis the dispersion of the particle size of the refractory aggregate other than graphite and X is the average particle diameter. Particles can be densely packed by this process to suppress the infiltration of slag, powder, or the like. Preferably, the amount of the refractory having particle diameter of >355 μm is adjusted to 0.5-6.0 wt.% to form a molten layer of the refractory aggregate and suppress the melt damage to the remaining refractory aggregate. Preferably, the refractory aggregate contains 70-98% ZrO2 or MgO to stably form the molten layer of the refractory aggregate.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To stably control negative drive force or negative drive torque over a wide range. SOLUTION: When a drive force command value or a drive torque command value is negative, the state of an engine is set to one of a throttle valve fully open and fuel cut forbidden state (state 1), a throttle valve fully open and fuel cut state (state 2), and a throttle valve open and fuel cut state (state 3). Thus, negative drive force or negative driving torque can be realized stably with high accuracy over a wide range in response to command values. When the command values are changed, negative drive force and negative drive torque can be smoothly changed without causing fuel cut-recover hunting or shock.
