Q: What kind of iron does it have? What is iron? What is iron?: The difference between the categories of iron and steel of carbon / impurities (such as sulfur and phosphorus) mechanical properties of 2-4.3 cast iron machining hard brittle cast forged steel 0.03-2 can not be less hard and tough, elastic cast steel is can exercise at high temperature, the oxidizer (such as oxygen) the iron contained in the too much carbon and other harmful impurities (such as sulfur and phosphorus) removal, provisions of the scope of them reach the steel content.

Q: The difference between iron and wrought ironDon't say one is raw, the other is ripe: Because the graphite is soft, with lubrication, so the cast iron has good abrasion resistance, cutting and casting performance. But it is not anti digital strength, it is not only used for producing all kinds of forging, casting, such as a variety of machine tool bed casting base, iron pipe. Ductile iron to carbon exists in spherical graphite morphology the mechanical properties of gray iron, far and close to steel, it has excellent casting, machining and wear resistance, has a certain flexibility, widely used in the manufacture of gear, crankshaft, piston and a variety of advanced casting machine parts. In addition to silicon, manganese, nickel or other elements of a particularly high amount of iron, alloy such as iron, ferrosilicon, ferromanganese, commonly used as raw material for steelmaking. In certain alloy steel-making pig iron, steel can improve performance.

Q: How to weld iron castings? Which welding method is adopted? What kind of electrode?: In the manufacture and use of cast iron parts, cracks, porosity and damage often occur. According to statistics, in normal circumstances, reaching the wear limit of this kind of parts, change its size is only 0.08% ~ 0.40%, quality loss is only 0.1% ~ 1.8%, the scrap parts, is undoubtedly very wasteful. Therefore, it is necessary to study and make use of the advanced repair experience to repair the cast iron parts reasonably. Welding is a very effective way to repair cast iron parts.

Q: What type of cutter car for NC lathe?: YG3X, in the hard alloy, the most wear-resistant, mainly the use of fine cars. The speed is about 300-400. The diameter is greater than 200 and the speed is under 200.CNC lathe processing is a high-precision, efficient automatic machine tool, using digital information to control parts and tool displacement machining method. It is an effective way to solve the problems of variety, small batch, complex shape and high precision of aerospace products and parts, as well as to realize high efficiency and automatic processing.

Q: Pig iron electrode welding high speed steel is good?: Suitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.

Q: What is the difference between pig iron and ordinary iron?: People often say iron refers to the steel and iron, the two is the main carbon amount divided, usually carbon content is less than 0.0218% that of pure iron and steel is between 0.0218% to 2.11% of the carbon content, carbon content of greater than 2.11% is cast iron.

Q: 307 can welding rod weld pig iron?: If the pig iron pieces more important, from quality assurance can be used on the cold welding welding process, selection of materials suitable for cold welding of cast iron electrode WEWELDING777 welding current, low current 90-110A welding.

Q: How can I get rid of the rust on pig iron?: Chemical treatment is actually a method of acid cleaning and rust removing. It uses acid solution and metal oxide (rust) to produce chemical reaction, which can produce salt and break away from metal surface.Commonly used acidic solutions are: sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid. Operation will be acidic solution coated on the metal rust parts, so that it slowly and rust chemical reaction and removed. Rust removal after the use of clean water erosion, and weak alkaline solution for neutralization and reflection, and then rinse with clean water after drying and drying, in case of rust soon

Q: What's the difference between pig iron and nickel iron?: Pig iron is an alloy of iron and carbon carbon content more than 2%, pig iron carbon content is generally in 2.11%--4.3%, including C, Si, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products. According to the different form of carbon in pig iron, it can be divided into several kinds, such as steelmaking pig iron, casting pig iron and nodular cast iron. Pig iron performance is hard, wear-resistant and casting good, but pig iron is crisp, can not forge.

Q: How is pig iron tempered?: Iron is rich in natural reserves, accounting for 5% of the total content of the earth's crust, ranking fourth in the earth's material. Iron is very active and easily combined with other substances.
