Boiler plate is used to manufacture superheater, main steam pipe and boiler fire chamber heating surface with hot rolled medium-thick plate material, the main materials are high-quality structural steel and low alloy heat-resistant steel, commonly used boiler steel are flat furnace smelting of low carbon sedentary steel or electric furnace smelting of low carbon steel, the carbon content of Wc in the range of 0.16% to 0.26%.The following is a detailed description of the boiler plate:
I. Performance requirements
As the boiler steel plate at medium temperature (below 350ºC) under high pressure, in addition to withstand high pressure, but also subject to impact, fatigue load and corrosion of water and gas, so the performance requirements for the boiler steel is mainly a good welding and cold bending properties, a certain degree of high-temperature strength and resistance to alkali corrosion, resistance to oxidation and so on.Second, the main steel and the implementation of standards
1. Main steel grades of boiler plate: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng.
2. Pressure vessel plate: 20R, 16MnR, 15MnNbR, 15MnVNR.
3. Implementation standards: GB713-1997, GB6654-1996.
Boiler container plate standards are different, the steel number is also different, of which the national standard classification includes Q345R, Q245R, etc., specific specifications and properties are as follows:
1.Q345R
Definition: Q345R is an ordinary low alloy steel, commonly used in boilers and pressure vessels, the delivery state is divided into hot-rolled or normalised.
Sign method: Q for "Qu" the first letter of hanyu pinyin, 345 for yield strength value, R for "Rong" the first letter of hanyu pinyin.
Properties: good overall mechanical properties and process performance, phosphorus, sulfur content is slightly lower than the low alloy high-strength steel plate Q345 (16Mn) steel.Tensile strength between (510~640), elongation greater than 21%, zero degree V-type impact work greater than 34J.
2.Q245R
Definition: Q245R is mainly used for pressure vessels, for the purpose of use, temperature, corrosion resistance of different, should be selected by the container plate material is different, the delivery state is hot rolled, controlled rolling, normalised.
Sign method: Q is the first letter of "Qu" Hanyu Pinyin, 245 is the yield strength value, R is the first letter of "Rong" Hanyu Pinyin.
In addition, the boiler plate also includes 16MnDR, 15CrMoR, 09MnNiDR, 12MnNiVR, 14Cr1MoR, 12Cr2Mo1R, 12Cr1MoVR, 13MnNiMoR, 18MnMoNbR, 15MniDR, 20MnMoR, etc. The thickness ranges from 8.5kg to 8.5kg.In terms of specifications, its thickness ranges from 8 to 300mm.
