Recently, China Environmental Industry Association held an expert review meeting in Beijing to review the low-temperature denitration technology of vanadium-vanadium sintering flue gas in Xichang and passed the vote without a vote. This marks the Xuanchang steel vanadium vanadium titanomagnet sintering flue gas NOX control technology in the sintering machine flue gas denitration technology innovation has been recognized by the authority.

"Vanadium titanium magnetite sintered flue gas NOX control technology" from Xichang Steel and Vanadium, Institute and Sichuan Environmental Protection Science and Technology Co., Ltd., Landing Environmental Protection Technology Co., Ltd. and other units jointly developed. In view of the current immature, high-cost and unsuitable process route for sintering high-sulfur vanadium-titanium magnetite flue gas at low temperature, the research group has been researching and solving several series of sintering process parameters to continuously control and reduce the sintering process parameters Sintering NOX generation, take full advantage of the unique advantages of vanadium-titanium magnetite, containing a unique vanadium, titanium and other metal particles in the sintering ash to add a certain amount of material, developed a multi-stage dense phase semi-dry method Calcium-based desulfurization system used, cheap denitrification catalyst, Xichang steel and vanadium sintering flue gas to effectively solve the problem of low-temperature denitrification to achieve a multi-stage dense phase semi-dry desulfurization and denitrification device integration, to ensure the efficiency of the desulfurization , Denitrification efficiency up to 58%, the export of flue gas NOx concentrations far below the current national emission standards, the current technology has been the patent declaration.

Experts pointed out that the R & D application of this technology has played an extremely important role in exploring the application of the low-temperature denitration technology for sinter flue gas, and has resulted in the reduction of NOx formation during sintering and the integration of desulfurization and denitration in a multi-stage semi-dry desulfurization tower Key technology, the development of efficient, low-cost low-temperature denitrification catalyst, denitrification in the sintering of flue gas technology blooms splendid.

Die Guide Components

Guide sleeve

Guide sleeve is a mold accessory which is used together with guide pillar to play a guiding role.

Mold Components, used together with guide pillars, play a guiding role. Generally, the fit clearance is very small, within 0.05mm; generally, they are mostly used in molds or some machines to ensure the accuracy of movement.

Die guide sleeve, also known as die guide sleeve, high-strength brass bearing, is on the base of high-strength brass. A high performance solid lubricant product embedded with graphite or MoS2 Solid lubricant. It breaks through the limitation that the general bearing relies on oil film lubrication. In the process of using, the solid lubrication and the shaft are rubbed by the friction heat, forming the excellent condition of oil and powder coexisting lubrication, which not only protects the shaft from wear, but also makes the solid lubrication characteristic eternal. Its hardness is twice as high as the common copper sleeve, and its wear resistance is also twice as high.

shape
There are five basic shapes of solid inlaid bearings: straight sleeve, flange sleeve, sliding block, thrust gasket and bearing bush. In case of good hardness, high wear resistance, no oil supply, high load and low speed, it can give full play to superior performance, superior drug resistance, corrosion resistance, flexible design, simple, convenient and rich standard products, which can be used with standard axis.

application
It is widely used in high temperature, high load, low speed and heavy load occasions such as metallurgical caster, train support, steel rolling equipment, mining machinery, ships, steam turbines, etc.
