A steering knuckle with reduced mass and similar or improved strength, stiffness, and durability is contemplated. The knuckle relies upon a mussell-shell shaped body that is three dimensionally asymmetric and constantly curving, except for the hard connection points commonly encountered in such components. The body is made of a single-layer wall that has a substantially similar or constant thickness, and its perifpheral shape is non-linear.

A method of catching overflow of a liquid fluid utilized to cast a component is disclosed. Sand is compacted to form a mold. A cutter of a cutting device is in a disengaged position spaced from a top surface of the mold when the cutting device is in a first position and the cutter is in an engaged position engaging the top surface of the mold when the cutting device is in a second position. The cutter is actuated when the cutting device is in the second position and the cutter is in the engaged position to remove sand from the top surface to define a recess therein to catch overflow of the liquid fluid. The recess is spaced from an opening. At least one blocking mechanism, blowing mechanism and adjustment mechanism is utilized to assist the cutting device.

A method of operating a shaft furnace includes inserting a mixture including anthracite coal and coke into a cavity defined by the furnace, and disposing a metal feedstock within the cavity. The method includes injecting natural gas at a natural gas flow rate and a first quantity of oxygen gas at a first oxygen gas flow rate into the cavity simultaneously through at least one burner. The method also includes driving a second quantity of oxygen gas at a supersonic oxygen gas flow rate into the cavity through at least one lance, wherein the supersonic oxygen gas flow rate is greater than the first oxygen gas flow rate. The method also includes combusting the mixture within the cavity to produce a stack gas, melting the metal feedstock to produce a melted metal material, and monitoring the stack gas to thereby operate the shaft furnace. A shaft furnace is also disclosed.
