_ Blowing lance supply pipe manufacturer (certified) _ lance

Lance improve toughness, corrosion resistance and bending properties of the way! It is a consumable lance, is dedicated smelting, the study found lower carbon content improves the corrosion resistance of the lance, impact toughness and ductility. However lance spot price, in the case where the carbon content reduced to obtain 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 of the silicon can easily lead to decarburization, the supply of the lance and therefore, the silicon content is controlled to 1.6 ~ 2.1wt%; adjusted added Cr, Ni, Cu, corrosion pits morphology control, to improve the corrosion resistance, corrosion fatigue performance, obtain the required hardening and maintain adequate low-cost steel to ensure that the new economy; micro-alloying elements Ti, V, Nb steel can be finely dispersed in the distribution of carbon nitride precipitates, these precipitates particularly those containing V 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. Oxygen tube manufacturers Hot Dipped Aluminum is blowing process aluminized pipe manufacturers commonly used surface treatments, hot dipped aluminum is aluminized common means, how Oxygen tube manufacturers are operating it? Points on hot dipped aluminum craft: 1, surface cleaning lance attached to the surface to clean oil, rust and oxides. 2, fluxing in fluxing agent (hydrochloric acid for industrial use 1000 kg + zinc Block 2 ~ 5 kg) were immersed for several minutes, and then quickly dried at about 150 ℃. 3, hot-dip aluminum liquid hot-dip aluminum industrial aluminum liquid is generally 92% to 94% and 6% to 8% iron small-diameter thin-walled lance, also adding 0.5% to 2% of silicon, in order to increase liquidity aluminized layer and reduce brittleness. 4, the optimum temperature of hot-dip process parameters is 760 ℃ ~ 800 ℃; holding time is generally bulky 30 ~ 50 min, steel, wire even shorter; nickel-based alloy and heat-resistant steel holding only a few seconds. To corrosion for the purpose of blowing pipe, hot dip may not have the diffusion annealing. When in high temperature oxidation resistance for the purpose of holding 4 ~ 6h need at 950 ℃ ~ 1050 ℃, furnace cooling to below 500 ℃ baked cooled. Diffusion annealing will improve the aluminized layer brittle, increasing the thickness, so that the surface is smooth and beautiful lance.
