Oxygen tube is used for steelmaking oxygen tube, generally with small diameter welding pipe, specifications by 3/8 inch - 2 inch eight. With 8, 10, 15, 20, or Q195 - made of Q235 steel strip. For corrosion protection, some aluminized processing.
Aluminized fire resistant coating oxygen tube (PS) series PS series consists of substrate layer, internal aluminized layer, the outer wall of aluminized layer, internal coating and coating, etc. A total of five layers, is based on S series product development, combined with the actual needs of the current electric arc furnace steelmaking, high refractoriness, less consumption, convenient operation, etc.
(1) in the eaf steelmaking oxygen or other gas, the electric arc furnace melting and refining of steel. (2) into the other powder additives, adjust the steel grade or refining special steel. (3) the removal of oxygen in the converter slag. (4) other USES, such as strong in  heat resistance, oxidation resistance, resistance to sulfide and corrosion resistance, etc.
The consumption is low. High temperature resistant coating together form a powerful heat resistance and oxidation resistance, can be up to * * * * limit oxygen consumption, reduce the cost.
High quality: from the screening of raw materials to finished products produced by each production process are in strict quality control management.
Low price: the advanced production equipment to form * * * * * *, has realized the product quality and cheap.
Oxygen tube is widely used in buildings and industrial areas such as, how oxygen tube is clean and warm up? Before spray (cast) shoot processing, adopt the method of cleaning to remove oil and scale on the surface of the oxygen tube, the heating furnace for preheating tube body a 60 to 40 ℃, the oxygen tube surface dry state. In spray (cast) processing, such as oil free oxygen tube surface dirt, can strengthen the effect of cleaning, dry the surface of the oxygen tube also is helpful for steel shot, steel grit and the separation of rust and scale, make after rust removal of oxygen blowing tube surface more clean.
Automobiles, machinery accessories have a high request for the precision of steel tube, bright and clean degree of the machinery. Precision steel tube users is not only for high precision and smooth finish demand users, for precision tube of high precision, tolerance can maintain in 2 -- 8, so a lot of machining the user to save the labor, material, at the time of the loss, the seamless steel tube or round steel is slowly into precision tube.
Precision tube elements on the effect of high temperature tempering brittleness is divided into:
(1) precision tube of high temperature tempering brittleness of impurity elements such as phosphorus, tin, antimony, etc.
(2) in different forms, different degree increase or decrease high temperature tempering brittleness of the alloy elements. Such as chromium, manganese, nickel, silicon promote role, and delay effect on molybdenum, tungsten, titanium, etc. Carbon also plays a promoting role.
General carbon precision tube of high temperature tempering brittleness. Sensitive, containing chromium, manganese, nickel, silicon binary or complex alloy steel is very sensitive, the sensitive degree depends on the alloy elements and different kinds and content.
Tempering precision tube of the original organization on the sensitive degree of high temperature tempering brittleness of steel has significant difference. Martensite high temperature tempering organization for high temperature tempering brittleness sensitivity is the largest, bainite high temperature tempering times, pearlitic structure is minimal.
Precision tube of high temperature tempering brittleness nature, generally regarded as phosphorus, tin, antimony, arsenic and other impurity elements in the original austenite grain boundary, lead to the result of grain boundary embrittlement. And alloy elements such as manganese, nickel, chromium and the impurity elements in grain boundary occur together, promote the impurity element enrichment and aggravate embrittlement. And molybdenum, on the other hand, with impurity elements such as phosphorus has strong interaction,
can make the intracrystalline phase precipitation and prevents the grain boundary of phosphorus together, can reduce the high temperature tempering brittleness of rare earth elements also has a role similar to that of the molybdenum. Impurities such as titanium more effectively promote the phosphorus element in the intracrystalline precipitation, impurities and decreases the grain boundary of partial poly slows down the high temperature tempering brittleness.
Lower precision tube of high temperature tempering brittleness measures are:
(1) cold oil or water fast cooling after high temperature tempering to suppress impurity elements in grain boundary to be partial to get together;
(2) using molybdenum precision light tube, when the content of molybdenum in steel up to 0. 7%, the high temperature tempering embrittlement tendency is greatly reduced, more than the limit of 20 # precision steel pipe in formation of molybdenum carbide special rich, molybdenum content in the matrix is reduced, precision tube embrittlement tendency but increases;
(3) the lower the content of impurity elements in the 20 # precision steel tube;
(4) components in the high temperature temper embrittlement area for a long term, single and molybdenum can also be difficult to prevent embrittlement, only lower content of impurity elements in the 20 # precision steel tube, improve the purity of precision tube, and supplemented by aluminum and composite alloying of rare earth elements, can effectively prevent the high temperature tempering brittleness.
