大型工业转换炉用蓄热球 松承常年供应

蓄热球介绍

      蓄热球是通过高温烧结而成，它材质的主要成分是氧化铝。具有强度大，耐高温、耐高压、耐强酸碱腐蚀，抗震稳定性好的特点，以工业氧化铝和耐火高岭土为主要原料，经科学配方、成形和高温煅烧制成的，耐火瓷球较高耐热温度可达到1900度。按照滚制和机压成型法两种。密度高、热阻小、强度高、导热性能好、抗氧化、抗渣性强、导热率和热容量大、蓄热效率高；热稳定性好、温度剧变时不易破裂等优点.比表面积可达到240m2/m3。

      在使用时蓄热球将气流分割成很小流股，气流在蓄热体中流过时，形成强烈的紊流，有效的冲破了蓄热体表面的附面层，又由于球径很小，传导半径小、热阻小、密度高、导热性好，故可实现蓄热式烧嘴频繁且快速换向的要求。主要用于化工行业的高温、高压、腐蚀性强的工作环境，是广大石油、化工行业中转化炉、反应炉、填料塔中较为理想的填料。

Regenerative ball is through high heat sintering, its material mainly of alumina. Has the strength, resistance to high temperature, high pressure resistance, strong acid and alkali corrosion, seismic stability of good characteristics, industrial alumina and refractory kaolin as the main raw material, through scientific formula, forming and high temperature firing, made of refractory porcelain ball maximum heat resistant temperature can reach 1900 degrees. According to the roll system and machine pressure molding in two. High density, small heat resistance, high strength, good thermal performance, strong oxidation resistance, slag resistance, thermal conductivity and thermal capacity big, high thermal efficiency; Thermal stability, temperature change is not easy to fracture, etc. Specific surface area of 240 m2 / m3.

When use regenerative ball will flow into small flow, air flow in regenerator have been out of date, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and as the ball diameter is very small, small transmission radius, small heat resistance, high density, good thermal conductivity, which can realize regenerative burner frequent and rapid directional control requirements. Mainly used in chemical industry of high temperature and high pressure, strong corrosive environment, is in the petroleum, chemical industry conversion furnace, reactor, the ideal packing tower packing.
