TECHNOLOGICAL LINE NITRIDING metals and alloys and the line boots and raw material drying

摘要

The invention relates to the field of ferrous metallurgy, in particular to the preparation of nitrided metal and ferro-alloys, the method of self-propagating high-temperature synthesis (SHS), which are used steel by alloying.; The production line nitriding metal and ferroalloy contains multireactor installation nitriding equipped with systems azotosnabzheniya and cooling reactors equipped with instrumentation connected to the central switchboard, with control and regulation of the central current shield to pilot light, temperature and pressure in the reactors, as well as lifting and transport mechanism and line loading and unloading of containers. Hoisting-and-transport mechanism is arranged to service reactors, as well as loading and unloading of container lines, storage of raw materials and finished products. In embodiments, the number of reactors is at least 4; azotosnabzheniya system provided with a heat-insulated cryogenic vessel, gasifying installation ramp nitrogen cylinders high pressure reducing gear, azotoprovodami azotoprovodami reactors and waste in the form of suppositories, the instrumentation of the system are designed as pressure gauges; cooling reactor provided with a main make-up and a distillate reservoir, the primary and secondary circulating pump, a filter, a blower fan of water cooler, the instrumentation of the system are designed as flow meters, thermocouples and pressure gauges; as a handling mechanism used with floor control valve; container load line is equipped with a three-position rotary table mounted in the crane service area; Container discharge line is equipped with a cutting table installed in the service area of ​​the crane.; raw material loading and drying line provided with vacuum means and technological vakuumprovodom containers, made with the possibility of connection to vakuumprovodu. These containers are provided with two sets of interchangeable caps, one group - to load the raw material, and the other - for drying of raw material. Instrumentation of this line are designed as vacuum gauges and electrified hydrometers connected to the central panel.; In preferred embodiments, the reactor container configured as a cylindrical body with detachable gas-permeable walls and is provided with a bag filter disposed within the housing; reactor container body made of a grooved metal sheet; means for creating a vacuum is made in the form of a pump fan type and at least one liquid ring pump with a feed pump connected via valves to a common vakuumprovodu equipped with a cyclone, with the suction line of the pump fan type filter is mounted, and on the liquid ring pump suction line a check valve;; pump-type blower and a water ring pump means for creating a vacuum connected to vakuumprovodu, with inclusion accordingly only when loading raw materials and only by drying the raw material; means for producing a vacuum is provided a backup liquid ring pump, connected in parallel to the main liquid ring pump.
