THREADED Connector

1) oxygen lance: Blows the oxygen is the modern strengthening smelting fast steel-making must the method, at present, the domestic and foreign open hearth furnaces, the ectric steelmaking fire door blows the oxygen to use traditional mostly the line pipe and aluminizes the tube. In order to reduce trades the tube number of times, reduces the worker labor intensity, reduces the smelting time, decreases the steel tubing consumption and the steel-making cost, my factory and the scientific research department develop the production to be newest highly effective, the energy conservation coating fireproof oxygen lance. This product has the oxidation resistance, the anti-high temperature heat shock, undergoes the multiple temperature change, but does not burst, and has the thermal conductivity to be high, the heat expansion rate is small, intensity higher characteristic. 2)STL oxygen lance use: (1) in the arc furnace steel-making transports the oxygen or other gas, in arc furnace melting and fining steel and iron. (2) pours into other powdery chemical additives, adjusts the aluminum or refines the special steel. (3) eliminates in the oxygen converter's gangue. (4) other uses, like in strong heat-resisting, aspects and so on oxidation resistance, anti-curing and corrosion resistance. STL oxygen lance characteristic: thelow consumption - - thermostable coating forms the formidable thermal stability together and the oxidation resistance, may achieve the threshold oxygen lance consumption, reduces the cost expense. high grade - - from raw material screening to end product manufacture each production link in strict quality control management. thelow price - - advanced production equipment forms the production line, has realized the product high quality at low price. thewholesale showed that theunderstanding wholesale details please relate seller .
