Lance lance spot price _ _ Gray Industry

Lance improve toughness, corrosion resistance and bending properties of the way! It is a consumable lance, is dedicated smelting, the study found lance spot prices, lower carbon content improves the corrosion resistance of the lance, impact toughness and ductility. However, in the case of reducing the carbon content to achieve the same strength, the tempering temperature must be reduced, as far as possible to control the carbon content in 0.45 ~ 0.55wt%; silicon can increase the yield strength and toughness, but in the heat treatment process Silicon can easily lead to decarburization, therefore, the silicon content is controlled in 1.6 ~ 2.1wt%; adjusted added Cr, Ni, Cu, corrosion pits morphology control, to improve the corrosion resistance and corrosion fatigue properties of the lance, to obtain the desired The hardening and maintain sufficient to ensure that the new low-cost steel economy; micro-alloying elements Ti, V, Nb steel can be finely dispersed in the distribution of carbon nitride precipitates small diameter thin-walled lance, these precipitates particularly those containing V-phase precipitates is favorable for obtaining high hardness and yield strength. Nb, Ti and a small amount of V, the austenitizing process helps control the grain size, to obtain small tissue, thereby improving the lance toughness, corrosion resistance and bending properties. Shandong Liaocheng Grenada Pipe professional production of oxygen blowing lance is used as a steel pipe, usually with a small diameter welded steel pipe lance phone manufacturers, specifications -2 inch by 3/8 inch eight. Made 08,10,15,20 or Q195-Q235 strip. For corrosion, and some aluminized treatment. Aluminized refractory coating lance (PS Series) Ps series consists of a base layer, the inner wall of the aluminized layer of aluminized outer layer, inner layer and a topcoat, a total of five layers, the S series is developed on the basis and a combination of the actual needs of the current arc furnace steelmaking, high refractoriness, low consumption, and convenient operation. Before spraying (throwing) radio processing, using cleaning methods to remove grease and fouling lance surface, using oven preheated to 40 for a tube 60 ℃, so that the surface of the lance to keep dry. In spray (throwing) radio processing, due to oil and other free lance surface dirt, rust can enhance the effect of blowing dry tube surface is also conducive to steel shot, grit and separation of rust and scale, so lance surface rust after more clean.
