Casting nickel alloys
For casting molten steel is passed through a hole in the bottom of the ladle. Kipyaschayastal, cooling, gives shrinkage, which leads to considerable internal stresses. Compensate them refractory forms of silica sand mixed with refractory (fireclay) clay. The form must have a substantial compliance with the cooling of steel, so establish a special profit for casting power. To conserve metal often use small profits, but under gas pressure. The main disadvantage of steel castings — shrink sink. With proper heat treatment and removal of these evils cast steel acquires high strength, not conceding on quality forgings. There casting technology of thin-walled parts weighing a few grams, introduced the production of cast tool.
Iron and steel casting process on molding machines and peskometami. Use conveyors to fill the forms and tape feeding molding compounds. After the heat treatment threshold is reached the tensile strength of steel products of 200 kg / mm2 and elongation more than 10%.
Casting nickel alloys
Nickel alloys melted in electric arc furnaces usually with the addition of dopant materials. To improve the properties of nickel-chromium alloys is used: boron, vanadium, tungsten, magnesium, molybdenum, cobalt, niobium, silicon, manganese, copper and titanium. If the atomic weight of alloying elements and their crystal lattice parameters are similar in structure to the substrate steel, hard alloys obtained with the complete «dissolution» of all the components and form a material with new properties. Being uniformly distributed throughout a solid solution alloying elements give the required performance of the steel. So, carbide and nitride alloys have high heat resistance, chemical resistance, high hardness.
Reducing the carbon content in the steel below 0.03%, gives it ductility, corrosion resistance and the share of expensive master alloy is substantially reduced. Especially low-carbon brand can work in extremely harsh environments, use of the products in this period increased by 2 — 2.5 times. New casting technology allows to expand the assortment of smelted brands (today there are about 100), to improve the quality of castings allow to smelt low carbon chromium-nickel steel to the world standards of recycled without the addition of a fresh batch. The use of new technologies makes it possible to control the chemical purity and mechanical advantages of the product. Volume Converter allows you to custom orders volume of 3.5 — 5 tons.
