Description
Technical field
The utility model belongs to high melt field, especially relates to the high temperature resistant gate of a kind of high leakproofness.
Background technology
In some pyrometallurgical smelting devices, be provided with barricade at present, to isolate melt or flue gas, but barricadeBe fixed, cannot change its position and length, and in actual production, along with the change of technological parameterChange, often need a kind of adjustable barricade, such as gate, as a kind of regulating stove of fast and flexibleThe means of ore deposit, steady production. On the other hand, if gate installation on the furnace wall of pyrometallurgical smelting device,Require gate system itself to there is good sealing, in case high-temperature furnace gas or melt are revealed; Meanwhile,Conventional pyrometallurgical smelting device, smelting temperature generally can reach more than 1000 DEG C, and the melt in molten bath has oneFixed acid-base value, also has stronger erosion, and current gate system generally can not seal, and also cannot expireThe harsh environment of above-mentioned high temperature resistant, corrosion-resistant, the resistance to erosion of foot, does not also apply lock in pyrometallurgy fieldThe precedent of door. Thereby develop a kind of good airproof performance, can be applicable to high temperature, corrosion and erosion strong simultaneouslyValve system in harsh environment is one, high melt field problem anxious to be resolved.
Summary of the invention
