TL 852系列碳硫分析仪,系在TL 851系列碳硫分析仪的基础上,吸收国内外90年代仪器制造技术和碳硫分析技术,精心设计、精心制造的新一代分析仪器,技术先进,性能可靠,受到用户欢迎。 1 TL 852电弧燃烧炉 电弧炉已有25年的历史,它最大的特点是省电、省时,能对样品实现高速燃烧。但早期的电弧炉对样品的燃烧是不完全的,究其原因有二:一是电弧功率低,能量小,对样品的引燃效果差,尤其是特种样品,更是无能为力;二是采用铜锅燃烧样品。铜是热的良导体,样品燃烧过程中产生的热量(电弧炉热量的主要来源)绝大部分被铜锅传递吸收,燃烧温度达不到碳硫分析所需的高温,碳硫回收率低,且不稳定。 TL 852电弧燃烧炉,采用高频高能电弧,电弧功率达4kW。不仅适用于普通卷状样、屑样,对较难燃烧的粉末样和炉前甩片样等特种样品,均有很好的引燃效果,引燃率达100％。 TL 852电弧燃烧炉,采用陶土坩埚燃烧样品。陶土为保温材料,热传导率比铜低几个数量级,可充分利用样品燃烧过程中产生的热量,提高炉温和高温持续时间,有利于碳硫的充分完全氧化。
Based on the TL 851 series carbon and sulfur analyzer, the TL 852 series carbon and sulfur analyzer absorbs domestic and international 90s instrument manufacturing technology and carbon and sulfur analysis technology, elaborately designed and elaborate new generation of analytical instruments with advanced technology and performance Reliable, welcomed by users. 1 TL 852 Electric Arc Furnace Electric arc furnace has 25 years of history, its greatest feature is the power, save time, can sample high-speed combustion. But the early EAF combustion of the sample is not complete, for two reasons: First, the arc power is low, the energy is small, the ignition of the sample is poor, especially the special samples, but also powerless; second is the use of copper Pan burning sample. Copper is a good conductor of heat. Most of the heat generated during the combustion of the sample (the main source of heat in the EAF) is transferred and absorbed by the copper pan, the combustion temperature does not reach the required high temperature for carbon and sulfur analysis, the carbon and sulfur recovery rate is low, And unstable. TL 852 electric arc furnace, the use of high-frequency high-energy arc, the arc power of 4kW. Not only for ordinary roll-like samples, crumbs samples, the more difficult to burn powder samples and other special samples before throwing pieces, have a good ignition effect, the ignition rate of 100%. TL 852 electric arc furnace, using a clay crucible to burn the sample. Clay is a thermal insulation material, the thermal conductivity is several orders of magnitude lower than that of copper, which can make full use of the heat generated in the combustion process of the sample and improve the duration of the furnace temperature and the high temperature, which is favorable for the complete and complete oxidation of the carbon and sulfur.
