An object of the present invention is to provide a taphole cooling structure allowing to prevent the wear and deformation of peripheral bricks of a taphole for taking out solutions from a furnace body, and to maintain a stable operation of the furnace in a high copper matte grade operation and high-load operation.Means for Solving the ProblemsTo provide a structure for cooling a taphole provided with a hollow jacket body to be inserted into an opening penetrated on a furnace wall, wherein a water passage is installed in the internal of the said jacket body for circulating cooling water while a flange made of the same material as the above furnace wall is provided on the periphery of the said jacket body to be weldingly connected to the said furnace wall, wherein a refractory material is filled within a hollow of the said hollow jacket body and perforated with a taphole for draining the solutions from the furnace body.
摘要:
The present invention provides a method of operation and a facility for the same suppressing the generation of dioxins in the combustion exhaust gas and efficiently reclaiming heat from high temperature combustion exhaust gas when firing and reducing fines of chromium ore, iron ore, or other ore or pellets formed from dust sludge, etc. containing iron oxide or other metal oxides generated in the metal industry in a reducing rotary hearth furnace. This treats the combustion gas generated in the reducing rotary hearth furnace to make the temperature of the gas 800° C. or higher for at least a certain time, to make the concentration of the carbon monoxide not more than 200 ppm in terms of volume ratio and to achieve a sufficiently well developed turbulent state at least at one of the inside of the exhaust gas outlet duct and the vicinity of the exhaust gas outlet duct for at least a certain time, then rapidly cooling the gas. Further, it controls the total number of moles of zinc and lead, the total number of moles of alkali metals, and the total number of moles of halogen elements contained in the combustion exhaust gas to a predetermined ratio.

摘要:
An organopolysiloxane gum is prepared by polymerizing a cyclic organopolysiloxane with a low molecular weight linear organopolysiloxane end-blocked with a triorganosilyl group in the presence of a thermally decomposable catalyst. After the polymerization reaction, the catalyst is deactivated by heating the reaction product under a subatmospheric pressure of typically up to 500 mmHg.
