Abstract
The utility model relates to a steel outer wall of an iron tap channel of a blast-furnace with a water cooling and monitoring function. Vertical steel plates on both sides on an outer metal wall of an iron runner are designed in a double-layered hollow structure, and cooling fins are arranged between the two steel plates. Then water is introduced, the steel plate is greater than 10mm thick, and the water temperature difference of temperature measuring sensors at inlet end and outlet end is monitored. Water cooling on both sides of a main runner is independent circulation. Through the water temperature difference, the thickness of a fireproof material on the iron runner wall is monitored, and the greater the water temperature difference between the inlet and outlet is, the thinner the fireproof material on the iron runner wall is. The steel outer wall provided by the utility model has the advantages that the service life of the pouring material in the iron runner is prolonged by way of water cooling; through measurement of the water temperature difference between the water inlet and outlet, the water temperature difference numerical value is transmitted to an information center in real time, and the using condition of the fireproof material in the iron runner is monitored, so that the safety is ensured.

The utility model proposes a kind of iron runner steel plate outer wall design that possesses simultaneously monitoring and refrigerating function.Except possessing general protection and fixed action, also possesses refrigerating function, can improve to a certain extent the iron runner life-span, cool off by water cycle, the warm gradient of refractory materials in the artificial increase ditch, heat in the ditch in the refractory materials conducts current through the outer wall steel plate, and heat is taken away by current; Possesses in addition temperature-monitoring function, pass through temperature-monitoring function, the monitoring feed-water end is in the water temperature difference of water side, because flow velocity substantially constant in the water cooler, by the water temperature difference, can monitor iron runner wall refractory thickness, the larger explanation furrow bank of the water temperature difference of import and export refractory materials is thinner, improves to a certain extent the accuracy to the iron runner monitoring.
Know-why of the present utility model is: 1, take away heat by the current in the Clad Steel structure of both sides; the thermograde of artificial increase ditch inwall refractory materials; thereby can form at inwall under the later stage limiting case and freeze the purpose that the iron layer reaches the protection refractory materials, improve iron runner work-ing life.2, the temperature probe of installing by the turnover water end (W.E.) of both sides water coolant reaches the purpose that water temperature difference is imported and exported in monitoring, infers the thickness of both sides iron runner refractory materials part by water temperature.
Key problem in technology principle of the present utility model is taken away heat by current, monitors iron runner running condition by the monitoring water temperature simultaneously.
The utility model has the advantage of:
1, prolongs the work-ing life of mould material in the iron runner by water-cooled method.
2, by measuring water-in in the water temperature difference of water outlet, the service condition of refractory materials in the monitoring iron runner is with the safety of guaranteeing.
